Spiral welded pipe in the economy as a whole the application scope is extremely broad,played a great role in conveying gas, transportation and as a structure.
What is the Spiral Welded Pipe？
Spiral welded pipe(SSAW pipe, also called HSAW pipe). The pipe is formed by spiral submerged arc welding technology,made using narrower sheets or hot rolled coils.It is to roll low carbon carbon structural steel or low alloy structural steel strips into tube blanks at a certain helical angle (called forming angle), then weld the tube seams together. It can be produced with narrower strips and Large diameter steel pipe. Its specifications are expressed by the outer diameter and wall thickness,the welded pipe should ensure that the hydraulic test, the tensile strength of the weld and the cold bending performance meet the requirements.Commodities implement APISPEC5L, EN10217, GB/T9711.1, GB/T9711.2 standards.
Spiral welded pipe Inspection process:
