What are the implementation standards for seamless steel pipes?

2023-11-27

The outer diameter of hot-rolled seamless steel pipes is generally greater than 32mm and the wall thickness is 2.5-75mm. The outer diameter of cold-rolled seamless steel pipes can be up to 6mm and the wall thickness can be up to 0.25mm. The outer diameter of thin-walled pipes can be up to 5mm and the wall thickness is less than 0.25mm. Rolling has higher dimensional accuracy than hot rolling

Hot rolled seamless steel pipe production principle

2023-11-16

A pipe production process in which a heated solid ingot is rolled into a hollow pipe body with no seams around the perimeter. The hot rolling method can be used to produce carbon steel, alloy pipes, high alloy steel and some non-ferrous metal seamless pipes, with an outer diameter ranging from 16 to 1600mm and a wall thickness of 2 to 200mm.
