Difference between Stainless Steel Seamless Pipe and Stainless Steel Welded Pipe

Stainless steel seamless pipe is a long steel with a hollow cross section and no seams around it. The wall thickness is uneven, and the internal and external brightness of the pipe is low.

It is generally used as a material for high strength and high pressure structures.

The blanks of stainless steel welded pipes are mainly steel plates and strip steel, which are generally divided into spot welded pipes, welded pipes, automatic arc welded pipes or spiral welded pipes and straight seam pipes according to the welding form.

Stainless steel seamless pipes can be divided into hot-rolled seamless steel pipes and cold-drawn seamless steel pipes according to the manufacturing process.

From the perspective of production technology, stainless steel welded pipe production equipment is simple, and it is relatively easy to change the product specifications and varieties. The welding process generally uses inert gas shielded arc welding, which reduces the cost by 25% compared with the seamless pipe of the same specification. The manufacturing process is relatively complicated and requires high production equipment. Each link will affect the quality of stainless steel seamless pipes.

From the perspective of production use, welded pipes are mainly used to transport water, oil, gas, air, and generally lower pressure fluids such as hot water or steam, and other uses. Some welded pipes can also be used for mine pressure, drainage, shaft fangs and other aspects.

Stainless steel seamless pipe can be used in engineering and large-scale equipment to transport fluid pipelines, and can also be used in power station and nuclear power plant boilers to withstand high temperature and high pressure fluid transport headers and pipes.
