Hot finished seamless steel pipe
Hot Finished Seamless (HFS) as differentiated from Cold Drawn Seamless (CDS) pipes and tubes are made by heating a solid billet or bloom and then punching or piercing it to make a hollow out of it. This hollow is subsequently passed through one or multiple stands with or without a tool inside to give it the final pipe or tube dimensions.
It is possible to manufacture large diameter and thick pipes of various grades in high volume through the HFS process. With the improvement in technology, HFS pipes & tubes now come with close dimensional tolerance & good surface finish.
HFS tubing is a cost effective alternative to cold drawn with a wider tolerance range. Hot Finished Seamless mechanical tubing is manufactured to OD and wall dimensions.
Benefits of Hot Finish Seamless (HFS):
Cost effective heavy wall tubing
Excellent candidate for most processing techniques.
Wide range of sizes available
HFS tubing is made from 1020/1026 Steel
Meets ASTM A519 & A106 standards
Cut to length service available
Applications of hot finished pipes & tubes.
HFS tubes are for high pressure and heavy duty applications that require strength. They are used in a broad range of applications, including hydraulic cylinders, drilling equipment, bushings, spacers, axles, rollers and sleeves.
