ASTM A252 ERW Carbon Steel Pipe Tube

ERW Carbon Steel Pipe Tube Used For Low Pressure Liquid Transportation

ERW (Electric Resistance Welding) is a process used to manufacture pipe, and the result is ERW pipe. These pipes can be identified by looking for a stencil on the side of the pipe that says “Type E.” The American Society of Mechanical Engineers (ASME) provides the guidelines and specifications for all pipe manufacturing, meaning that pipes manufactured using the ERW process can safely transport gases and liquids as well as provide structural support. The main use of ERW steel pipe is in low to medium pressure applications. A common example would be the transportation of water or oil. Another common use of this type of pipe is pipe piling and in the cable pipe systems.

Low pressure fluid conveying with welded steel pipe and galvanized welded steel pipe, low pressure fluid conveying in welded steel pipe, is made from carbon mild steel, is one of the most commonly used in pipeline engineering of small diameter pipe material, is suitable for conveying medium such as water, gas, steam, according to its surface quality is different, divided into galvanized pipe (commonly known as galvanized iron pipe) and the galvanized pipe (commonly known as black pipe). Internal and external wall coating a layer of zinc on the maintenance, but also about the galvanized layer of 3% 6%. According to the pipe wall thickness of different can be divided into: thin wall pipe, the common pipe and thickening. 

Usage:Used for construction field, low pressure liquid transportation, in various engineering purposes, fencing, scaffolding etc.
