Product Description

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

 

1. Product Description 

Forged steel flanges are high-strength disc‑type connectors made by hot‑forging carbon, alloy, or stainless steel. The forging process refines grain structure and eliminates voids, ensuring uniform density and reliable mechanical properties. They are manufactured to ASME, DIN, JIS, EN, and GB standards, in all standard types and facing styles.

2. Product Applications 

Used to connect pipes, valves, pumps, and equipment in oil & gas, chemical, power generation, shipbuilding, water treatment, and food/pharma industries. Suitable for steam, oil, gas, water, chemicals, and cryogenic fluids under normal to extreme conditions.

3.Product Advantages 

  • Higher strength and impact resistance than cast or plate flanges.

  • Excellent corrosion and erosion resistance due to low carbon and fine grain.

  • Reliable sealing with precision‑machined faces, suitable for high pressure and temperature.

  • Longer service life and reduced maintenance costs.

  • Full traceability and compliance with international standards.
