Stainless Steel 304 Seamless & ASTM A312 TP304 ERW Pipe

Check Dimensions of Schedule 40 304 stainless steel pipe, Supplier of Stainless Steel 304 Pipe and SS 304 Welded Pipe

Stainless Steel 304 Pipe is a steel pipe made up of chromium nickel alloyed austenitic stainless steel used extensively in stainless steel applications. The 304 is the most commonly used stainless steel in the world. The pipes come in different types and manufacturing methods and Roopam Steel supplies all types. The Stainless Steel 304 Seamless Pipe is drawn from a single billet to form the pipe. This makes the pipes seamless and to have higher dimensional accuracy. The material is strong with 215 MPa minimum yield strength and 505MPa minimum tensile strength. The Stainless Steel 304 Pipe & SS 304 Welded Pipe unlike the seamless pipes is made from welding a strip or plate from end to end either spirally or longitudinally.

Most electric resistance welded pipes are welded spirally from strips. The ASTM A312 TP304 ERW Pipe  therefore is strong but has seam and is less accurate in wall thickness. The electric fusion weld is used to produce larger diameter pipes. There are ASME SA 312 Grade 304 Square Pipe and other shapes of pipes. These pipes can operate under elevated temperatures as high as 889 degrees Celsius. There are different pressure classes such as UNS S30403 schedule 40 pipe and other schedules. The DIN 1.4307 AISI 304 Rectangular Pipe is used in applications that require structural strength. Please feel free to contact us for more product details and for any inquiries. Roopam Steel one of the biggest 304 stainless steel pipe supplier in India, We stock and supply different sizes and standards of pipe such as schedule 40 304 stainless steel pipe, schedule 10 304 stainless steel pipe, astm a312 tp 304, astm a312 tp304 erw, asme sa 312 tp 304 in different countries like UAE, Saudi Arabia, Oman, Qatar, South Africa.
