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.
