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. So, let's learn about the characteristics of spiral welded pipes!

The difference between spiral welded pipe and ordinary steel pipe
Small-diameter welded pipes mostly use straight seam welding, and large-diameter welded pipes mostly use spiral welded pipes to bend the hot-rolled strip into a spiral shape, and perform inner and outer seam welding through submerged arc automatic welding to form spiral welded pipes. The difference between spiral welded pipe and ordinary steel pipe specifications!
Complete solution of main hardness index of spiral welded pipe
The steel pipe with the ratio of the outer diameter of the steel pipe to the wall thickness is less than 20 is called a spiral welded pipe. Mainly used for petroleum geological drilling pipes, petrochemical industry cracking pipes, boiler pipes, bearing pipes and high-precision structural pipes for automobiles, tractors, aviation, etc. Then, let’s learn about the main hardness indicators of spiral welded pipes.
