Technical requirements for ERW steel pipe

　　With its special technical production process, ERW steel pipe can be applied in various qualities, wall thicknesses, and diameters of the finished pipes. This would be the contribution of the technical technology. Today, we will discuss the technical requirements of this kind of tube mainly.

　　Yield strength would have the customized range. For ERW steel pipe, we would control it higher than the J55 up to 173 ~ 206 MPa.

　　If your tube products under the same size, orientation, minimum size, then we will figure out that relative products can absorb lower than N80 steel grade.

　　Of course, for the nondestructive testing methods of seamless pipe, coupling stock, welded steel pipe like ERW one would be different from them.

　　Of course, the color would be different due to the technical requirement’s difference.
