Seamless pipe introduction:

Seamless steel pipe is formed by forcing molten metal through a circular die with a plug in the center to form a long tube of continuous metal, which is then cut to the proper length; usually 21 feet or 40 feet.

Unlike seam-welded rolled and welded pipe, seamless pipe has a more uniform consistency. Seamless pipe can withstand higher working pressures and temperatures than welded pipe, and fluid flow through seamless pipe is generally less turbulent than that of welded pipe.

This carbon steel pipe is a kind of pipe that is extruded or rolled in one piece and has no welded joints and welding points. Seamless steel pipe because of its no weld manufacturing process, can greatly reduce the stress, which also creates its uniform wall thickness, the overall strength of high characteristics, so seamless steel pipe is very suitable for high temperature and high pressure environment, as well as corrosive environment applications.

Application info:

Seamless steel pipes are a suitable choice for applications involving elevated, or corrosive substances. They find utility in a wide range of scenarios, such as heat exchangers, chemical plants, power generation facilities, shipbuilding, and oil and gas sectors, as well as for applications requiring high pressure resistance.

Seamless steel pipe has a very wide range of application markets, in the selection of seamless pipe, it is necessary to choose according to the environmental conditions of the project and the performance requirements of the pipe.

Aerospace: ASTM B241 6061 Seamless steel pipe for light weight and high strength.-- Oil and gas industry: API 5L seamless steel pipes are often used in pipe systems such as drill tubes. --Reactor piping: ASTM A312 316L seamless steel pipe has good resistance to high temperature and corrosion.
