Manufacturing of tp304 cold worked pipe and annealed pipe

Mcneil Instrument offers a wide range of AISI 304 stainless steel pipes, renowned for their versatility and reliability in various piping applications. These SS 304 pipes come in different material grades, dimensions, finishes, and mechanical properties to suit diverse needs.

Among the varieties available, cold worked and annealed pipes stand out. The cold worked pipes are meticulously crafted by drawing raw material into shape without the need for forging or welding. During production, the material undergoes heating and controlled cooling to achieve the desired shape. Variants like ¼ hard, ½ hard, ¾ hard, and full hard cater to specific requirements.

In the case of cold worked SS 304 pipes, reheating is an option to enhance temper and ductility. Annealing processes, including solution annealing or bright annealing, are employed for this purpose. These procedures entail heating the material to precise temperatures, followed by controlled cooling, ensuring it cools at a rate similar to that under normal air conditions. Solution heat treatment typically occurs within the temperature range of 1010 to 1120 degrees Celsius.

Mcneil Instrument a top manufacturer, supplier, and exporter is committed to delivering top AISI 304 stainless steel pipes, manufactured using advanced processes to meet stringent quality standards and exceed customer expectations.
