This article introduces four types of pipes suitable for air lines: black steel pipe, galvanized pipe, aluminum alloy pipe, and stainless steel pipe.

Cold drawn precision seamless steel pipe refers to processing steel plates or steel strips into various types of steel through cold drawing, cold bending, cold drawing and other cold processing at normal temperature.

In order to improve the surface hardness and wear resistance of a500 square and rectangular tube, it can be heat treated.

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.
