High hardness wear resistance steel pipes are composed of the wear base material and the wear layer, the wear layer is generally accounts for 1/3or 2/3 of total thickness; .
The wear layer and the base material is combined through metallurgy, so that the wear layer can’t fall off, and can bear stronger impact.
The pipes are processed and molded by two methods, one is that chromium carbide overlay wear plate is rolled by roller press. the other is that we firsthand weld in the seamless steel pipe.
The performance of wear layer in the pipes is the exactly same with chromium carbide overlay wear plate.
The pipes wear resistance steel pipes connection methods are flange connection and welding;
The pipes can be processed into elbow,tee branch,Square to round Transitions,frustum,Square tube,etc
