Steel Pipe for Rollers
Steel pipes for rollers are crucial elements designed specifically to meet the demands of roller applications across numerous sectors.
Cold-rolled seamless steel pipes have high dimensional accuracy, it is a common material for rollers due to its high strength, good toughness, and excellent weldability.
HAOTAN is a seamless steel pipe manufacturer and supplier, offering uniform strength in all directions and being easy to bend and form into different shapes

Seamless Steel Pipe Manufacturing Process
The round steel bar is used to produce seamless pipe. After heating the bar to a high temperature, a probe is put into the bar to produce a hole. The cylinder is then moved to rollers that shape it to the required diameter and wall thickness.
