The service life of the spiral welded pipe is related to the surface decarburization of the spiral welded pipe. If the surface is decarburized, the strength and wear resistance of the spiral welded pipe will be reduced, which directly affects the service life of the spiral welded pipe. If the decarb

Industrial Steel Round Bar ExportWhen the mechanical performance requirements are high, after tempering and tempering treatment. Cold deformation plastic medium, annealing and normalizing have better machinability than quality. Used to manufacture high-strength parts, such as gears, shafts, piston p

Steel pipe processing and furnace installation:1. Workpieces that are easily deformed during heat treatment should be heated on a special fixture.2. The workpiece should be placed in the effective heating zoneWarm-up:1. For workpieces with complex shapes or sharp changes in cross-section and large e

There are many reasons for the formation of "sagging" of steel pipe anti-corrosion coatings, so there are also many issues that must be paid attention to. These are the key points that need to be controlled. The following points must be ensured:1. Anti-corrosion coated steel pipes must ensure a cert
