Differences from welded pipes:

7 Jan 2019

1. Production process
Seamless pipes are made through hot rolling or cold rolling processes, while welded pipes are made through welding processes.
2. Strength
Seamless pipes have higher strength and better pressure resistance.
3. Surface quality
Seamless pipes have smooth surfaces, while welded pipes have weld seams on their surfaces.
4. Cost
Seamless pipes have higher production costs, but they offer better performance.
5. Application scenarios
Seamless pipes are mostly used in high-pressure, high-temperature or corrosive environments, while welded pipes are mostly used in low-pressure, normal-temperature environments.

Raw material preparation Heating

Select high-quality steel billets as raw materials, heat the billets to high temperatures (about 1200°C) to soften them.

Perforation Rolling

The billets are punched into hollow tube billets by a perforator. Hot rolling, cold rolling, cold drawing.

Heat treatment

Annealing or normalizing treatment is performed to improve the mechanical properties and processing properties of the material.

Straightening and cutting

Adjust the straightness and roundness of the seamless pipe by a straightener. Cut into specific lengths according to requirements

Surface treatment

Pickling, polishing or coating treatment is performed to improve surface finish and corrosion resistance.

Packaging

Use anti-rust paper and steel strapping to prevent damage during transportation.

Our product - seamless steel pipe
