Corrosion in steel pipes occurs because metals are sometimes susceptible to chemical reactions that weaken them. Once the metal is weakened, it becomes susceptible to rust and can form cracks and holes, which is a big problem. Therefore, it is vital that steel pipes are protected against corrosion,

As a terminal technology product in the steel pipe industry chain, anti-corrosion steel pipes have always occupied a very important position in the industry. In recent years, with the development and application of new anti-corrosion technologies for steel pipes, anti-corrosion steel pipes have beco

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

1. Welding seam defects: Welding seam defects are serious and need to be compensated by manual mechanical grinding. The resulting grinding marks will cause the surface to be uneven and affect the appearance. Only pickling and passivating the welds also result in uneven surfaces.2. Scratches are diff
