What is ERW Pipe? The Complete Guide from a Factory Perspective
By understanding the manufacturing process, standards, and applications of ERW steel pipes, you can save your project from high costs without compromising on quality.
LSAW Pipe is subdivided into UOE, RBE, JCOE steel pipe according to its different forming methods.
LSAW Pipe has the characteristics of relatively simple process and fast continuous production, and has wide use in civil construction,petrochemical, light industry and other sectors.
Mostly used to transport low-pressure fluids or made into various engineering components and light industrial products.

The difference between ASTM A333 steel pipe and ASTM A106 steel pipe is that ASTM A333 is a low-temperature carbon steel pipe that can be used as a structural pipe, while ASTM A106 is a non-structural carbon pipe that is used in high-temperature applications.
Carbon steel pipe/ tube, also called CS pipe, are widely used in heavy industries like infrastructure, shipping, stills, mineral, oil, gas, and fertilizer industry pipeline systems.
Hot rolled seamless pipe is processed at high temperatures, resulting in a rougher surface and looser tolerances but lower cost. Cold drawn seamless pipe undergoes further processing at room temperature, delivering tighter tolerances, higher strength, and a smooth finish, though at a higher price point.
