ASTM A691 Alloy Steel Welded Pipes Manufacturing Process
The performance of alloy steel welded pipes depends greatly on controlled manufacturing methods and quality procedures.
The manufacturing process includes:
Raw Material Selection
High-quality alloy steel plates are selected according to required grades and specifications. Chemical composition and mechanical properties are verified before production.
Plate Forming
The steel plates are shaped into cylindrical form using advanced forming equipment while maintaining dimensional accuracy.
Electric Fusion Welding (EFW)
The formed plates are joined using the electric fusion welding process. This creates a strong welded structure suitable for pressure applications.
Heat Treatment
Heat treatment improves mechanical properties, reduces welding stresses, and enhances overall performance.
Finishing & Sizing
The pipes are straightened, sized, and finished according to dimensional requirements.
Final Inspection
Every pipe undergoes testing and inspection before dispatch to ensure quality and specification compliance.
