Carbon Steel Forged Flange Socket Weld ASME B16.5 150# Raised Face
1. Product Description
Forged steel flanges are premium pipe connectors manufactured by hot forging from carbon, alloy, or stainless steel. The process ensures a dense, grain‑oriented structure with no internal defects. Conforming to ASME, EN, JIS, DIN, and GB standards, they are the industry standard for reliable, high‑integrity piping joints.
2. Product Applications
| Flange Type | Best Suited For |
| Weld Neck (WN) | High-pressure, high-temperature, or cyclic service; pipelines, boilers, power plants, refineries. Tapered hub reduces stress concentration. |
| Slip On (SO) | Low-to-medium pressure, non-critical service; water, air, steam lines; cost-effective and easy to align. |
| Blind (BL) | Closing pipe ends, pressure vessel manways, and test connections; provides easy access for inspection. |
| Socket Weld (SW) | Small-bore lines (NPS ≤ 2″) carrying high-pressure fluids; hydraulic systems, instrument lines. |
| Threaded (THRD) | Small-bore lines where welding is not permitted; galvanized piping, explosive environments. |
| Lap Joint (LJ) | Systems requiring frequent dismantling; low-pressure, non-corrosive media; used with stub ends. |
| Orifice | Flow metering applications; installed between orifice plates with pressure taps for differential pressure transmitters. |
3. Product Advantages
✅ No porosity – Forging eliminates casting defects, ensuring zero leakage risk.
✅ Higher strength – Superior tensile, yield, and impact values vs. cast/plate.
✅ Better fatigue life – Grain flow follows component shape, resisting cyclic loads.
✅ Corrosion resistant – Low carbon and alloy options withstand aggressive media.
✅ Interchangeable – Dimensional accuracy ensures fit with mating flanges globally.
✅ Full traceability – Heat number, mill certificates, and NDE records provided.
