Hot Finished Seamless Mechanical Tubing ( HFS Tubing)

In the production of pipes, tubes, and fittings, hot finished seamless tubing is used. It is used in the pipe industry to produce seamless pipes. Other industries, such as automotive and construction, have also used it. Many industries use hot finished seamless tubing.

The hollowing out of Cold Drawn Seamless (CDS) and Hot Finished Seamless (HFS) pipes and tubes is accomplished by heating a solid billet or bloom and punching or piercing it. The hollowed out pipe or tube is passed through one or more stands with or without a tool.

Large diameter and thick pipes can be manufactured in high volumes using the HFS process. With improved technology, HFS pipes & tubes now have tight dimensional tolerances and good surface finishes.

construction, have also used it. Many industries use hot finished seamless tubing.

The use of seamless tubing is varied, and it is a specialized material that is used when necessary. As a production line item or high quality material, it has been used to make pipes and tubes without seams where the quality of the pipe, tube or fitting cannot be enforced on other materials. 

Pipes, tubes, and fittings are made with the hot finished seamless tubing, which offers a high level of quality and is extremely cost-effective.

Hot finished seamless tubing is used in the automotive industry for the production of pipes and tubes without seams, where precision manufacturing is crucial. Different sizes of pipes, tubes, and fittings can be produced with it. Using special machines, it can be made into one seamless tube or pipe with no seams using hot finished seamless tubing.

There are two primary types of hot finished seamless tubing which are the high-temperature (hot) finish and the high-pressure (hot) finish. High-pressure hot finish seamless tubing has a pressure below 3,000 PSI while high-temperature hot finish seamless tubing has a pressure higher than 5,000 PSI. Hot-finished seamless tubing has a high degree of flexibility and strength.

The high-temperature seamless tubing can be used in hydraulic or hydraulic pressure pipes as well as hydraulic oil piping. Rubber hoses are difficult to find if you need them as emergency tools.

At competitive prices, USPTF offers a wide variety of elastic high temperature hot finished seamless tubing in different sizes and types of fittings. We can provide high-temperature hot finished tubing with a variety of fitting types, as well as the right size and type. At competitive prices, we provide high temperature hot finished seamless tubing in different sizes and fittings.

 

With a wider tolerance range than cold drawn tubing, HFS tubing offers a cost-effective alternative. OD and wall dimensions of hot finished seamless mechanical tubing can be specified. Hot finished seamless (HFS) pipes with an OD of 26.7mm – 88.9mm and a WT of 3mm – 15mm.

 

Hot Finished Seamless mechanical tubing is made from SEA 1026 carbon steel and produced using the same extrusion process, but without the final step of drawing at room temperature. Steel tubes produced by HFS are easily machinable and are ideal for applications without tight dimensional tolerances or smooth surfaces. In order to meet ASTM A519 standards, HFS steel tubing has thicker, heavier walls.4140
