180 Degree Steel Elbows
- Wide material range: Carbon steel, stainless steel, alloy steels, and special corrosion-resistant grades for harsh media and high-pressure service.
- Mature forming technology: Controlled medium-frequency heating and forming process keeps dimensions stable and bend radius accurate.
- Back wall thickness control: Strict process control ensures the critical back wall remains within specified tolerance.
- Reliable performance in service: Smooth internal curvature minimizes pressure loss, turbulence, and erosion at the direction change.
