API 5L ERW Pipe is a resistance welded pipe produced according to the API 5L executive marking standards.

304/304L ss(stainless steel) seamless pipe is one of the very important raw materials in the manufacture of stainless steel pipe fittings. It is a common chromium-nickel alloy stainless steel with good corrosion resistance and high temperature resistance, and is very suitable for manufacturing pipe fittings.

A500 ERW (Electric Resistance Welded) steel pipe refers to a type of steel pipe that is made using the electric resistance welding process and meets the specifications outlined in ASTM A500.

Theory and practice have proven that ERW tubes have the characteristics of reliability, safety and economy in oil and gas transportation applications.

The flattening test of ERW welded pipes can effectively and quickly uate the quality of welds and raw materials.

ASTM black steel pipe refers to a black steel pipe that conforms to the ASTM (American Society for Testing and Materials) standards.
