Product Description

Forged Steel RF Socket Weld Flange ASTM A105 150# B16.5

 

1. Product Description 

Forged steel flanges are high‑integrity connectors produced by hot forging from carbon, alloy, or stainless steel, with a dense, grain‑refined structure. Manufactured to ASME, EN, JIS, DIN, and GB standards, they are available in all standard types and pressure classes.

2. Product Applications 

These flanges are used in oil and gas pipelines, chemical plants, power stations, shipbuilding, water treatment, and pharmaceutical facilities. They connect pipes, valves, pumps, and vessels for conveying steam, hydrocarbons, chemicals, water, and cryogenic fluids under both normal and severe service conditions.

3. Product Advantages 

 

Forged steel flanges offer higher strength and impact resistance than cast or plate flanges. Their fine‑grained structure ensures excellent corrosion resistance and sealing reliability. Precision‑machined faces guarantee leak‑tight joints, while full traceability and compliance with international standards provide quality assurance.
