What are the functions of the Ministry of Standardization?

Partial standard pipe, also known as spiral welded pipe, is made by winding the steel strip of low carbon structural steel or low alloy structural steel on the tube blank at a certain helical angle (called the forming angle), and then welding the tube after sewing. Large-diameter steel pipes can be produced from narrow strips. Then, let's learn about the functions of the lower standard pipes!

The difference between spiral welded pipe and straight seam submerged arc welded pipe

The main difference between spiral welded pipe and longitudinal welded pipe is the difference in welding form. Spiral welded pipe is to roll low carbon structural steel or low alloy structural steel strip at a certain helix angle (also called forming angle) into a tube blank, and then weld it to form a pipe seam. Large diameter pipes can be produced from narrow strip steel. Spiral welded pipes are mainly spiral submerged arc welded pipes (SSAW), which are frequently used in the construction of various gas pipelines in my country. Its specifications are represented by "outer diameter * wall thickness". Spiral welded pipe has single-sided and double-sided welding. The welded pipe shall ensure that the hydrostatic test, tensile strength and cold bending performance of the weld meet the requirements.

Characteristics of spiral welded pipe

Spiral welded pipe is a spiral seam steel pipe with strip steel coil as raw material, which is often warmly extruded and bent into a spiral shape. The raw materials are strip coiling, welding wire, and flux. The quality and performance of the spiral welded pipe are determined according to the needs, and the content and types of different elements must be matched according to the needs. Then, let's learn about the characteristics of spiral welded pipes!
