Wear-resistant Composite Steel Pipe

Our company independently developed a new type of wear-resistant pipe with domestic advanced level. It is a super wear-resistant alloy material with steel pipe as the base, and the wear-resistant layer and the base form a solid metallurgical combination. It is fully automatic through the inner wall numerical control. The surfacing welding machine is directly surfacing on the inner wall of the steel pipe, which is suitable for wear-resistant pipes with small diameters; our company can produce all the inner diameters above 80mm. So far, the wear-resistant composite steel pipe can be divided into two types, one is the inner wall surfacing steel pipe, and the other is the rolled wear-resistant composite steel pipe.

The difference between them is that the rolled wear-resistant composite steel pipe can only be deformed and rolled into a tube when it is strongly squeezed by the rolling machine, so the adhesion between the wear-resistant layer and the base plate will be seriously damaged, resulting in falling off and falling blocks. The impact resistance and vibration resistance performance will be greatly reduced. Due to the plasticity of the substrate and the brittleness of the wear-resistant layer, and all the rolled tubes have joints, it is inevitable that the ovality error will be large.
