Difference between seamless and seamed stainless steel pipe

Stainless steel seamless and seamed pipe production process:

Stainless steel pipes are pipes used to transport various fluids. They are usually divided into two types: seamless pipes and seamed pipes (also called welded pipes). Stainless steel seamless pipes are manufactured by cold drawing or cold rolling methods and have the characteristics of short production cycle and smooth appearance. Stainless steel seamed pipes are manufactured by welding and other methods, and the production cycle is longer, but the price is relatively more affordable.

Performance characteristics of stainless steel seamless and seamed pipe:

1. Different pressure thresholds
Seamless stainless steel pipes have high strength and can withstand high pressure and high temperature conditions; while stainless steel seam pipes have a lower pressure threshold and are suitable for some low pressure and low temperature situations.

2. Reasonable selection
The two have different application scopes. Stainless steel seamless pipes are suitable for industrial fields with higher requirements, such as petroleum, chemical and other industries; while stainless steel seam pipes are suitable for some domestic and general industries, such as water supply, heating and other occasions.

3. Different corrosion resistance
Stainless steel seamless pipes have good corrosion resistance and will not rust, while stainless steel seamed pipes are prone to corrosion due to the oxide scale produced by the steel plates during welding.

Scope of application of stainless steel seamless and seamed pipe:

Based on the above performance characteristics, stainless steel seamless pipes are suitable for transportation pipelines in high-pressure and high-temperature environments, such as petroleum, chemical and other industries; while stainless steel seamed pipes are suitable for some low-pressure and low-temperature situations, such as water supply, heating, etc. In addition, stainless steel seamless pipes are also widely used in construction, transportation, machinery and other fields, and have broad application prospects.

In summary, stainless steel seamless and seamed pipes each have their own characteristics, and the appropriate pipe should be selected according to the actual situation. In the future, with the continuous advancement of science and technology, the application scope of stainless steel pipes will continue to expand, driving the development of the stainless steel industry.
