SA210-A1 Internally Threaded Steel Pipe

Henan Beibang Steel is a professional manufacturer of internally threaded steel pipes.
Key Product Advantages:
Structural Features:
Internal helical thread design enhances fluid turbulence and improves heat transfer efficiency (suitable for heat exchanger tubes).
Strong resistance to deformation; the threaded structure increases pipe body rigidity, and pressure resistance is superior to smooth pipes.
Materials and Processes:
Material options: carbon steel (Q235, 20#), alloy steel (15CrMo), stainless steel (304/316L), suitable for different media (corrosive/high temperature).
Cold-rolled/cold-drawn precision forming, thread accuracy up to ±0.05mm, ensuring sealing performance.
Application Scenarios:
Boiler heat exchange tubes: threads increase the heat transfer area, improving thermal efficiency by 15%-30%.
Hydraulic systems: internal threads reduce fluid resistance and pressure loss.
