Steel Pipes
Home / Products / Steel Pipes
Steel pipes and tubes are use in a wide variety of industries such as marine, mechanical, oil and gas and many more other industries. They are made using two different processes that lead to either welded or seamless pipes. In both processes, the raw steel is first formed into a more elastic initial form before being stretched out into a seamless tube or pressed together and joined with a weld to make a pipe. All pipes are measured by nominal inside diameter and wall thickness based on a schedule number. The thicker the wall, the higher the schedule number.
Welded Pipe
Description:
Welded pipe is a round pipe that has been electrically welded with raised weld seam inside the pipe. It is a structural grade tube appropriate for a broad range of applications where dimensional accuracy and precision tolerances are not of highest concern. The difference between seamless pipes and welded pipes are mainly the different in molding process where welded pipes are generally though the flat plate by welding after the bending. There are 4 class of welded pipes, which consists of ‘AA', 'A', 'B' and 'C'

Size Range:
15mm to 150mm
API Seamless Pipes / API ERW Pipes
Description:
Electric resistence welding, or ERW, is a welding technique that produces pipes with a more precise surface by just heating the edges. Pipes up to 0.4m in diameter might be manufactured more affordably in this way. The difference between seamless pipes and welded pipes are mainly the different molding process where seamless pipes are generally the molten steel through the annular slit of the backlog by stretching out before treatment processes. They are utilized for a variety of engineering reasons, including sewage, gas pipelines, LPG and other non-toxic gases, etc., as well as agricultural and irrigation.
