Manufacturing Process of Stainless Steel Pipe - mcneil Instruments Inc.

Manufacturing Process of Stainless Steel Pipe

Steel pipes are lengthy, hollow tubes with a multitude of uses. They are made using two different processes that yield seamless or welded pipes. Raw steel is initially cast into a more manageable initial form in both techniques. The steel is then stretched into a seamless tube or the edges are forced together and sealed with a weld to form a pipe. Early in the 19th century, the initial techniques for making steel pipe were created, and they gradually developed into the contemporary procedures we employ today. Millions of tonnes of steel pipe are produced annually. Because of its adaptability, it is the steel industry’s most widely utilized product.

There are many different locations for steel pipes. Because of their strength, they are utilised underground to move gas and water between towns and cities. They are also used in construction as a way to safeguard electrical cables. Steel pipes can be lightweight even though they are powerful. They are therefore ideal for use in the production of bicycle frames. They are also useful in, among other places, cars, street lamps, flagpoles, refrigeration units, heating and plumbing systems, and medications.

Raw Materials Using for Pies Manufacturing

Steel is the main raw material used in the manufacture of pipes. The main component of steel is iron. The alloy may also contain other metals such as manganese, aluminium, titanium, tungsten, vanadium, and zirconium. Occasionally, finishing materials are utilised in the production process.

if the pipe is coated, used. At the final stage of the production line, steel pipes are usually coated with a little amount of oil. In doing so, the pipe is more protected. A production stage involves the use of sulfuric acid to clean the pipe, even though it is not a component of the final product.

Design & Diameter of Pipes

Steel pipe comes in two varieties: seamless and with a single welded seam running the length of it. Each has a distinct purpose. The walls of seamless tubes are usually thinner and they weigh less. They are employed in the transportation of liquids and bicycles. Sealed tubes have greater rigidity and weight. They are usually straighter and more consistent. They are employed in plumbing, electrical conduit, and gas transportation, among other things. They are usually employed in situations when there is little pressure placed on the pipe.

During manufacture, several pipe qualities can be adjusted. For instance, the pipe’s diameter is frequently altered based on its intended application.  Small pipes used to create hypodermic needles and big pipelines needed to move gas throughout a metropolis can both have different diameters. It is also possible to regulate the pipe’s wall thickness. Often, the strength and flexibility of pipes will also depend on the type of steel used. Additional modifiable attributes encompass dimensions, type of coating, and final polish.

Maine Process of Pipes Manufacturing

There are two distinct methods used to create steel pipes. There are three steps in the entire production method for both processes. First, a more workable structure is manufactured from raw steel. After that, a continuous or semi continuous production line is used to create the pipe. In order to satisfy the needs of the customer, the pipe is finally chopped and altered.

Manufacturing of ingots (Metal Bar, Plate, or Sheets)

Iron ore and coke, a carbon-rich material produced when coal is burned without air, are melted together in a furnace to create molten steel. The carbon is then mostly removed from the liquid by introducing a high oxygen content. After that, the molten steel is poured into sizable iron mould with thick walls, where it cools to form ingots.

Ingots are formed between massive rollers under extreme pressure to create long items like bars and rods or flat products like plates and sheets.

Manufacturing slabs and blooms

The ingot is run through two stacked steel rollers with grooves to create a bloom. We refer to these kinds of rollers as “two-high mills.” Three rollers are used occasionally. The rollers move in opposing directions and are placed such that their grooves meet. The steel is compressed and stretched into longer, thinner pieces as a result of this motion. The steel is drawn back through, becoming longer and thinner, when the rollers are turned by hand. Until the steel takes on the required shape, this process is repeated. In order to process the steel evenly on both sides, devices known as manipulators flip the material.

Another method that can be used to roll ingots into slabs is related to the bloom-making process. The steel is stretched by passing it between two stacked rollers. To regulate the slabs’ breadth, there are additional rollers affixed to the side. The uneven ends of the slabs or blooms are chopped off and the steel is cut into shorter pieces once it takes on the required shape.

Additional processing

Before being turned into pipes, blooms are usually subjected to additional processing. By passing them through more rolling mechanisms that lengthen and narrow them, blooms are transformed into billets. The flying shears are the tools used to cut the billets. These are two synchronized shears that cut the moving billet by racing against it. This enables effective cutbacks to be made without pausing the production process. After stacking, these billets will produce seamless pipe.

Rework is also done on slabs. They are first heated to 2,200° F (1,204° C) to make them pliable. As a result, the slab’s surface develops an oxide layer. Using a scale breaker and high pressure water spray, this covering is removed. The slabs are subsequently turned into thin, narrow steel strips known as skelp by running them through a series of rollers on a heated mill. This mill has a maximum length of 0.5 miles. The slabs get longer and thinner as they go through the rollers. A single slab of steel may be transformed from a 6 in (15.2 cm) thick piece of material into a thin steel ribbon that can be as long as a quarter mile in roughly three minutes.

The steel is pickled after stretching. In order to clean the metal, it must pass through a number of sulfuric acid-filled tanks. After that, it is dried, rinsed in both hot and cold water, wrapped up on big spools, and packaged for shipping to a pipe manufacturing factory.

Manufacturing of Stainless Steel Pipes

Pipes are made from billets and skelp. Welded pipe is created from skelp. First, it is set up on an unwinding device. The steel spool becomes hot as it is unwound. After that, the steel is run through several rollers with grooves. The skelp’s edges curl together as it goes by due to the rollers. This results in an unsealed pipe.

Next, welding electrodes are placed over the steel. These fittings bind the pipe’s two ends together. After that, a high pressure roller is used on the welded seam to help ensure a tight weld.  The pipe is then stacked for additional processing after being cut to the required length. The continuous method of welding steel pipe can produce it at a rate of up to 1,100 feet (335.3 metres) per minute, depending on its size.

Square billets are produced when seamless pipe is required. They are formed into what is known as a round or cylinder shape by heating and molding. The circular is then exposed to extreme heat in a furnace. The hot round is then vigorously rolled. A hole forms in the middle of the billet as a result of the high pressure rolling. A bullet-shaped piercer tip is forced through the middle of the billet during rolling because of the irregular shape of this hole. The pipe may continue to have inconsistent thickness and shape after the piercing stage. It goes through an additional set of rolling mills to fix this.

The final stage of processing

Both kinds of pipes can go through a straightening machine once they are manufactured. In order to link two or more pieces of pipe, they may also be equipped with joints. Threading, which consists of tight grooves carved into the pipe’s end, is the most popular kind of junction for pipes with smaller diameters. Additionally, the pipes pass via a measuring device. The pipe has this information automatically painted on it along with other quality control data. Next, a thin layer of protective oil is sprayed onto the pipe. The majority of pipe is usually treated to stop corrosion. This is accomplished by galvanizing it, or applying a zinc coating. Other paints or coatings may be used, depending on how the pipe will be utilized.

Quality Control

Numerous steps are taken to guarantee that the final steel pipe satisfies requirements. For instance, steel thickness is controlled using x-ray gauges. Two x-rays are used for the gauges to function. A single beam of light is aimed toward a known thickness of steel. The other is aimed at the steel that is moving along the production line. The gauge will automatically cause the rollers to resize in order to make up for any differences between the two rays.

After the operation is complete, pipes are examined for flaws as well. Using a specialized machine is one way to test a pipe. This apparatus inserts water into the pipe and then raises the pressure to test the pipe’s capacity. Pipes that are broken are sent back for scrap.


In conclusion, steel pipes are versatile and widely used in various industries due to their strength and adaptability. They are made using different processes and are utilized for transporting gas and water underground, protecting electrical cables, manufacturing bicycle frames, and in various other applications. Steel is the main raw material used in their production, and they are often coated with oil for added protection.

Different Types and Uses of Stainless Steel Pipes - mcneil Instruments Inc.

Different Types and Uses of Stainless Steel Pipes

Stainless steel pipes are used to transport gas, hot and cold water, and other fluids in a safe manner. Small pipes have a welded joint in the middle of the length that you can’t see. Bigger pipes have either a welded joint or a riveted joint. Once such pipes have been manufactured, they are soaked in zinc solution. This process is referred to as Galvanizing, and is employed to prevent rusting of the pipe. The average lifespan of such pipes ranges from 25 to 50 years.

These pipes are lightweight and welded joints are used. They are installed on Open Supports and are also joined with Flanged Joints. These pipes are prone to bending and can be easily damaged by acids and alkali water. Repairing these types of pipes is challenging. Because of their lower wall thickness, these pipes are susceptible to external pressure.

There are five different types of stainless steel Pipes

Stainless steel is used in a variety of piping applications. Stainless steel is second only to carbon steel in Process industries due to its superior corrosion resistance characteristics. Stainless steel is an alloy steel with a chromium content of at least 10.5% and a carbon content of at least 1.20%.

SS is super corrosion-resistant and super easy to work with. It’s made by coating the surface of stainless steel with a non-reactive film of chromium oxide called Cr2O3. This film sticks to the metal and stops it from corroding. When the microstructure of Stainless Steel changed, its properties changed as well. Based on these changes, Stainless Steel can be categorized as follows;

1. Austenitic stainless steel

Stainless steels are made with a lot of different metals like chromium, nickel, manganese, and nitrogen, which are added to the iron base to give them their unique look.

AusteniticStainless steel has some really great qualities. Here’s a list of some of them.

  • Austenitic Stainless steel is magnetic-free and highly corrosion-resistant.

It doesn’t attract magnets and is immune to rust and corrosion due to exposure to moisture, chemicals and acids.

  • Excellent weldability, Formability, Fabricability & Ductility

Austenitic Stainless steel is known for its high weldability, which means it’s easy to join or weld onto other materials. It’s also really versatile, meaning you can shape and bend it into all sorts of different shapes without it losing its shape.

  • High Corrosion Resistance at 1500°F High corrosion resistance at 1500°F

It’s a special kind of stainless steel that won’t corrode at high temperatures, so it’s great for use in places where temperatures are high, like industrial furnaces or processing plants.

  • Austenitic Stainless Steel is suitable for both low and high temperature service.

Austenitic Stainless steel has excellent mechanical properties over a broad temperature range, allowing it to be used in both low and high temperature applications.

  • This form of stainless steel is resistant to corrosion through cold working.

Cold working processes, including rolling, bending, and hammering, can cause plastic deformation in Austrian stainless steel, thus increasing its strength and hardness and improving its mechanical properties.

  • The FCC is a cubic structure that is centered around the face.

Austenitic Stainless steel has a special structure called face-centered cubic, which means the atoms are all in one place. This helps it to be strong, ductile, and tough.

  • This Pipes has a lot of power when it comes to dealing with cold temperatures.

Stainless steel can withstand even the coldest conditions, which is great for cold conditions or when it’s exposed to sudden shocks or loads. It’s used a lot in process industries and in industrial settings, and even cookware is made from austenite stainless steel.

These types of stainless steel are used in a lot of different industries and have different compositions and properties depending on what they’re used for. Check out the graph below to see what types of stainless steel you can use.

2. Ferritic stainless steel

Ferritic stainless steel is a more cost-effective and corrosion-resistant steel than galvanized steel. Ferritic stainless steel has a magnetic nature and high carbon content, which can cause it to be brittle and not as corrosion-resistant as austenitic stainless. Carbon can cause carbides to form, which makes it harder for the material to resist corrosion and more likely to crack and break.

  • Ferritic Stainless Steel is not capable of being hardened by heat treatment.

Ferritic stainless steel isn’t as easy to harden as other stainless steel types because its microstructure doesn’t change much when it’s heated and cooled, so it’s not as easy to improve its mechanical properties with heat treatment.

  • Body-centered cubic (BCC) structure:

Ferritic stainless steel is made with a structure called body-centered cubic, which means all the atoms are in a lattice, with one atom in the middle of each one. This has a negative effect on the material, making it more fragile and less ductile than regular stainless steel.

  • High resistance to chloride stress corrosion cracking exists in ferritic stainless steel.

Ferritic stainless steel has a strong resistance to chloride stress corrosion cracking, which is a major benefit. This kind of corrosion manifests itself in chloride-rich settings, such as those that are marine or include chemical chlorides.

Ferritic stainless steel is frequently utilized in applications including naval equipment, petrochemical facilities, heat exchangers, and furnaces because of its resistance to this particular type of corrosion.

Ferritic stainless steel comes in types 409, 430, 439, 444, and 446. See the graph provided below.

3. Martensitic stainless steel

Martensitic stainless steel is an alloy of stainless steel that has a crystalline structure called martensitic. It can be aged and treated with heat to harden and soften it. One of the toughest forms of stainless steel now available, martensitic stainless steel is well known for its exceptional hardness. However, compared to austenitic stainless steel, it often exhibits inferior corrosion resistance.

  • High degrees of hardness are heat treatable:

Martensitic Stainless steel can be treated with heat to make it really tough, which is called quenching or tempering. Steel is heated up quickly to harden it and then cooled down again to make it softer. This process gives you more control over how hard the steel is and how tough it is.

  • Structure with altered crystallographic shape

When heat treatment is done on Martensitic stainless steel, the crystallographic structure changes from face-cantered to body-cantered. This causes the lattice structure to be distorted, which makes the material stronger and harder.

  • Uses of Manufacturing sports knives and multipurpose tools.

Stainless steel is a popular choice for sports knives, multipurpose tools, and more because it’s so tough and durable. It’s great for keeping your knife sharp and cutting, and it’s also tough enough to handle tough jobs.

Stainless steel isn’t great for things that need to be super resistant to corrosion or in harsh conditions, like knives and cutting tools. But it’s strong and tough, so it’s great for use in places where wear and tear is more important, like industrial applications. Check out the graph below to see examples of Type 405, Type 410, and Type 420.

4. Precipitation Hardening (PH) stainless steel

Precipitation Hardening Stainless Steels with are a type of alloys that resist corrosion. Some of them can be heated up to give you tensile strength of 850 MPa to 1700 MPa and yield strength of 520 MPa to over 1500 MPa.

Precipitation-hardened stainless steel, or PH stainless steel, is a special kind of stainless steel that has a special set of qualities.

  • Precipitation-hardened stainless steel can be heat-treated to a high strength and is magnetic:

PH stainless steel is usually magnetized because of its martensitic composition. It can also be heat treated to reach high tensile strength levels through precipitation hardening. Heat treatment is a process that causes fine particles to be precipitated into the steel matrix, making it stronger and harder.

  • Strong corrosion resistance and a very high strength-to-weight ratio:

Precipitated hardened stainless steel is super strong and lightweight, so it’s great for applications where you need to reduce weight without losing strength. Plus, it’s corrosion resistant, which is something you’d expect from stainless steel. It might not be as tough as austenitic steels, but it’s still pretty good.

  • It’s used to make parts and springs for planes.

The combination of high tensile strength, corrosion resistance, and low weight make precipitation hardened stainless steel an ideal material for aerospace applications.

Stainless steel is a popular material for making a lot of different parts of planes, landing gear, engines, and fastenings. It’s really strong, so it’s great for use in springs that need to be strong and resistant to corrosion. Popular examples of this type of steel are 17-7H and 17-4H.

5. Duplex or Super Duplex stainless steel

Duplex or Super Duplex stainless steels are built on a 25% chromium alloying addition, whereas duplex stainless steels are built on a 22% chromium alloying addition.

A well-balanced blend of austenite and ferrite phases defines the microstructure of Duplex and Super Duplex stainless steel. Austenitic and ferritic stainless steels’ respective characteristics are combined in this dual-phase structure.

  • Benefits of austenite and ferrite stainless steel are combined in this grade:

Stainless steel made from both ferrite and austenite phases has some great benefits. It’s stronger and more resistant to corrosion than ferrite steel, and it’s also more durable and formable than austenite steel. This means it’s better for a lot of different uses.

  • Excellent resistance to pitting and crevice corrosion

Crevice corrosion is a type of corrosion that can occur in confined areas or in crevices, where corrosive solutions have the potential to accumulate. Durable stainless steel, such as Duplex or Super Duplex, has a dual phase microstructure, which increases its resistance to these types of corrosion and makes it suitable for use in harsh conditions, such as in seawater.

  • High resistance to stress corrosion cracking and high strength:

Stainless steel made from Duplex or Super Duplex has a lot of strength, so it’s great for building materials that need to be strong. Plus, it’s really tough when it comes to corrosion, since it can handle a lot of stress and corrosion. That’s especially important when you’re working in tough places like oil and gas drilling.

  • Used in heat exchangers, structural applications, and the seawater system:

Duplex and Super Duplex stainless steel are widely utilized in a variety of industries because of their higher corrosion resistance, strength, and resistance to stress corrosion cracking.

Stainless steel is used in a lot of different types of marine applications, from offshore platforms to desalinated plants. It’s strong and corrosion-resistant, so it’s great for heat exchancers, structural parts, and other tough jobs in the oil and gas industry, chemical production, pulp and paper, and more. Examples of stainless steel made from Duplex or Super Duplex include EX-UNS (S32205), SEC (S31803), and SEC (S32760).
