Product Description
Carbon Steel Pipe/Tube are used to transport fluids, such as pipelines that transport oil, natural gas, gas, water, and certain solid materials. The seamless steel pipe with high carbon content is high -quality carbon structure steel. The seamless steel pipe 35# and 45# is most commonly used. The main purpose is to create a parent material for high -pressure wear resistance such as general mechanical shells.

1.Carbon Steel Square Tube
2.Carbon Steel Rectangular Tube
3.Seamless Square/Rectangular Tube
The square tube is divided according to the production process: hot rolled seamless square tube, cold drawn seamless square tube, extruded seamless square tube, welded square tube. Among them, the welded square tube is divided into:
(a) According to the process-arc welding square tube, resistance welding square tube (high frequency, low frequency), gas welding square tube, furnacewelding square tube
(b) According to the weld seam-straight seam welded square tube, spiral welded square tube
