ASTM A312 TP304 Stainless Steel Pipe

ASME SA312 304 Stainless Steel Seamless Pipe and SS 304 ERW Pipe manufacturer in India

We produce variations like the ASTM A312 Tp 304 Sch 10s which is a low pressure class. The pipes are used in the high temperature service industry. Due to the addition of titanium and molybdenum in the composition, the Stainless Steel Pipe ASTM A312 Tp304 is stronger and is also corrosion resistant. Our ASTM A312 Tp304 Efw pipes are electric fusion welded and are less vulnerable to localized corrosion. The A312 Tp304 Material has carbon, manganese, phosphorous, sulfur, silicon and titanium. This mixture makes the A312 Tp304 Smls pipes to be used in unique industrial applications.

The A312 Tp304 Pipe is either pushed or pulled to form the shape from usually a round billet of the raw material. It is more resistant to corrosion than the ordinary 304 Stainless Steel Pipe. Our 304 Stainless Steel Seamless Pipe low carbon content which makes it highly weldable and formable. The Stainless Steel 304 Welded Pipe can come in different shapes such as the SS 304 Round Pipe or the SS 304 Square Pipe. The SS 304 Erw Pipe is used in long service chemical and industrial applications. There are different schedules such as the SS 304 Sch 40 Pipe. Our products are made in superior quality and have highly competitive pricing in the market. You can contact us for a full price list and product list.

Manufacturing process of tp304 cold worked pipe and annealed pipe

The stainless steel pipes are one of the most used products in the piping applications. The pipes differ in material grades, dimensions and in the finishing and mechanical properties. 304 is the most used stainless steel product. There are cold worked and annealed types of pipes in the 304 grade of steel.

There are different procedures involving the making of these different types of pipes. The cold worked pipes are drawn from raw material. They are not forged or formed through welding. They are drawn to shape during production. This process involves heating and allowing the material to cool while drawing it to the desired shape. There are ¼ hard, ½ hard, ¾ hard and full hard types.

The cold worked pipes could be reheated to gain temper and to increase ductility. The annealing process can be solution annealing or bright annealing. These processes involve heating of the material to certain temperature and then allowing the material to cool rapidly but not faster than the rate at which it would cool under air. The solution heat treatment on 304 grade steel can take place in the range of 1010 – 1120 degrees Celsius of heat.
