seamless steel pipe
What is seamless steel pipe?
A seamless steel pipe is a circular pipe having a hollow section and no seams around it. Seamless pipes are considered superior to welded pipes as they are built using monolithic steel billets, with intrinsic mechanical strength, without seam welds.
How is seamless steel pipe made?
seamless steel pipes are produced by two distinct methods which result in either a welded or seamless pipe. In both methods, raw steel is first cast into a more workable starting form. It is then made into a pipe by stretching the steel out into a seamless tube or forcing the edges together and sealing them with a weld.
Where is seamless pipe used?
Seamless steel tubes for low and medium pressure boilers: used in the manufacture of various low and medium pressure boilers, superheated steam pipes, boiling water pipes, water wall pipes and superheated steam pipes for locomotive boilers, large smoke pipes, small smoke pipes and arch brick pipes.
Seamless Pipe Application:
Transporting oil & gas
Boiler and condenser tubes
