Spiral steel pipe oil and gas pipeline

Spiral welded pipe: It is made by rolling low-carbon carbon structural steel or low-alloy structural steel strips into pipe blanks at a certain spiral angle (called forming angle), and then welding the pipe seams. It can be made of narrower pipes. Strip steel produces large diameter steel pipes. Its specifications are expressed as outer diameter * wall thickness. The welded pipe should ensure that the hydraulic pressure test, tensile strength and cold bending performance of the weld meet the regulations.

Product Description

Spiral welded pipe: It is made by rolling low-carbon carbon structural steel or low-alloy structural steel strips into pipe blanks at a certain spiral angle (called forming angle), and then welding the pipe seams. It can be made of narrower pipes. Strip steel produces large diameter steel pipes. Its specifications are expressed as outer diameter * wall thickness. The welded pipe should ensure that the hydraulic pressure test, tensile strength and cold bending performance of the weld meet the regulations.

Spiral welded pipes are mainly used in water engineering, petrochemical industry, chemical industry, power industry, agricultural irrigation, and urban construction. Used for liquid transportation: water supply, drainage, sewage treatment engineering, mud transportation, ocean water transportation. Used for gas transportation: gas, steam, liquefied petroleum gas. Used as a structure: as a pile driving pipe, as a bridge; Pipes for docks, roads, building structures, ocean pile driving pipes, etc.
