What Are Flanges?
Flanges connect pipes, valves, and equipment, forming secure, leak-proof joints. PetroPipe offers flanges for high-pressure and corrosive applications.
Types of Flanges
Explore our range of flanges:
| Flange Type | Material | Sizes | Uses | Advantages | Certifications |
|---|---|---|---|---|---|
| Weld Neck | Carbon Steel, Stainless Steel | ½” to 48” | High-pressure pipelines | Durable, reduces stress | ASME B16.5 |
| Slip-On | Carbon Steel, Duplex | ½” to 36” | Low-pressure systems | Easy to install | ASME B16.5 |
| Socket Weld | Carbon Steel, Alloy Steel | ½” to 4” | Small high-pressure pipes | Strong joint | ASME B16.5 |
| Lap Joint | Carbon Steel | ½” to 24” | Frequent maintenance | Easy disassembly | ASME B16.5 |
| Blind | Carbon Steel, Nickel Alloys | ½” to 48” | Pipeline termination | Secure closure | API 6A |
| Threaded | Carbon Steel | ½” to 6” | Non-welded systems | No welding needed | ASME B16.5 |
