1. Fake and inferior thick-walled steel pipes are prone to folding.2. Fake and inferior thick-walled steel pipes often have pockmarked surfaces.3. Fake and inferior thick-walled steel pipes are prone to scarring on the surface.4. Fake and inferior materials are prone to cracks on the surface.5. Fake

1. Reasonable selection of materials. For precision and messy molds, micro-deformation mold steels with good materials should be selected, and mold steels with serious carbide segregation should be reasonably cast and quenched and tempered. Reasonable selection of heating temperature and control of

Large-diameter steel pipes are steel pipes with an outer diameter of more than 1000MM. Large-diameter seamless steel pipes are made of steel ingots or solid tube blanks through perforation to make capillaries, and then hot-rolled, cold-rolled, or cold-drawn.1. Chain cooling bed. In the past, a chain
