Pipe and Tube

It is used in various part of industry including piping, water supply, engineering, construction and it can be divided into several products based on each field.

│Description│

WELD PIPE (ERW/ EFW, Literal, ERW/ EFW)
There are divided into comparably lower pressure welding pipe which is used in the water supply, steam, air, oil and high pressured welding pipe which used for high pressure about 30~120kg/cm²

SEAMLESS PIPE (SML'S, Literal)
The Seamless Steel Pipes(SML'S) have no seam unlike welded pipe and it tis a absolute necessary pipe for special purpose such as machine structure service and heat exchange service including high pressure, high temperature, low temperature which cannot be used as the welded pipe.
It is widely used in varios industrial machine, chemical plant, nuclear, aerospace, automotive, shipbuilding, refrigeration condenser, boiler, and especially extensive and precision seamless steel pipe is used in the pneumatic cylinders, and semiconductor equipment piping, ship-piping.

Tubes (Welded, SML'S)
Mainly, it is used in non-ferrous metals or non-metal and because the thickness of pipe does not have to be thick as the ordinary pipe. It is divided into also Welded and SML'S tube like ordinary pipe.
It is widely important used in the small internal manufacturing service in heat exchangers, survey instrument, compressors, boilers and coolers.
