Technical requirements for steel bending pipes and analysis of factors affecting the quality of steel bending pipes
Steel bending pipes are produced step by step, and then made into finished products. In the whole production process, because the pipes are required to be curved, and the bending of the pipes requires some technology, the degree of bending is also different. Then What are the ...Read more -
Deviation and Forming Method of Large Diameter Steel Pipe in Production
Deviation of large-diameter steel pipes in production: common large-diameter steel pipe size range: outer diameter: 114mm-1440mm wall thickness: 4mm-30mm. Length: according to customer requirements can be made in fixed length or indefinite length. Large-diameter steel pipes ar...Read more -
The difference between hot-rolled seamless steel pipe and cold-rolled seamless steel pipe
In terms of processing technology: hot rolling is hot processing, and cold drawing is cold processing. Hot rolling is rolling above the recrystallization temperature, and cold rolling is rolling below the recrystallization temperature; Distinguish from the appearance: the surf...Read more -
