Detail

                        

 

  Abrasion Resistant Steel Pipe is produced by inner wall welding machine, the smallest pipe we can produce is diameter 80mm, thickness of the pipe wall is 5~30mm, the wear resistant pipe has dual metal characteristics, work layer is wear resistant and the base layer is flexible. Wear resistant layer contains high carbon and high chromium, also wear resistant layer with temperature resistance contains Mo, W, V, B, Nb, Ti and other alloy elements, the microstructure of wear resistant layer is eutectic +M7C3 carbide or complex carbide, the product with very good wearability and it can be applied under the circumstance of room temperature, high temperature, medium impact, low stress impact.
