Keywords :Details of large diameter 3pe anti-corrosion steel pipe Update : 2024-01-24 View(s) : 398
The base materials of large-diameter 3pe anti-corrosion steel pipes include seamless steel pipes, spiral steel pipes, and straight seam steel pipes. Anti-corrosion pipelines can be divided into two categories: lined anti-corrosion steel pipes and outer wall anti-corrosion steel pipes. The most commo...
Keywords :Spiral steel pipe submerged arc welding process instructions Update : 2024-01-23 View(s) : 389
Submerged arc automatic welding is a new welding method invented in 1940. The same thing as the previous manual welding is that it still uses slag protection, but this slag is not the coating of the welding rod, but a specially smelted flux. This flux system consists of a funnel that carries the flu...

The strip steel is bent into a spiral shape, and the inner and outer seams are welded by submerged arc automatic welding to make a spiral seam steel pipe. It is widely used in the production of large-diameter steel pipes for the following reasons: 1) As long as the forming angle ...
Keywords :Causes and improvement measures of surface cracks in stainless steel continuous casting slabs Update : 2024-01-18 View(s) : 441
During the continuous casting process, the crystal strength of the slab pulled out from the mold is very small at the solidification interface. When the external force (thermal stress, bulging force, pull roller pressure, straightening force) on the slab exceeds the critical value, cracks are genera...
