The Jiangsu Iron Flange is a forged carbon steel piping connection solution manufactured to ASME B16.5 standards. Available in pressure classes 150LB through 2500LB and sizes from ½ to 24 inches, these flanges deliver exceptional strength and reliability. Two sealing face options—Raised Face (RF) and Flat Face (FF)—accommodate diverse system requirements. The forging process ensures dimensional precision and structural integrity, making Jiangsu Iron Flange components suitable for water distribution networks, oil gathering systems, and natural gas transmission pipelines.
Types and Technical Specifications
| Flange Type | Pressure Range | Temperature Range | Sealing Faces | Key Application |
| Slip-On (SO) | 150LB–300LB | -29°C to +200°C | RF, FF | Low-pressure, non-critical systems |
| Weld Neck (WN) | 150LB–2500LB | -29°C to +425°C | RF, RTJ | High-pressure, high-temperature, critical services |
| Threaded (TH) | 150LB–300LB | -29°C to +150°C | RF | Small-diameter, welding-not-permitted areas |
| Blind (BL) | 150LB–2500LB | -29°C to +425°C | RF, RTJ | Pipe end sealing, equipment closures |
| Lap Joint (LJ) | 150LB–300LB | -29°C to +200°C | RF | Frequent maintenance, easy alignment |
| Socket Weld (SW) | 150LB–2500LB | -29°C to +425°C | RF | Small-bore, high-integrity welded systems |
Thread Standard (TH): NPT or BSP. Welding methods: SO and SW use single-sided fillet welds; WN uses double-sided butt welds.
