| Type | Standard | Typical use |
|---|---|---|
| Weld neck | ASME B16.5 (NPS ½ to 24), B16.47 Series A and B (NPS 26 to 60) | High-pressure and high-temperature lines |
| Slip-on | ASME B16.5 | Lower-pressure services where welding is simpler |
| Blind | ASME B16.5 and B16.47 | Closing line ends and nozzles |
| Socket-weld and threaded | ASME B16.5 | Small-bore lines |
| Lap joint with stub end | ASME B16.5 and B16.9 | Lines that need easy bolt-hole alignment |

- Material grade
- Standard: B16.5 or B16.47 Series A or B
- Quantity, certificates and required date
Frequently asked questions
What is the difference between ASME B16.5 and B16.47?
B16.5 covers flanges from NPS ½ to 24. B16.47 covers large-diameter flanges from NPS 26 to 60 in two series, A and B, which are not interchangeable, so your enquiry should state the series.
Do you supply RTJ flanges and ring gaskets?
Yes. We supply ring-type joint flanges and the matching R, RX or BX ring gaskets.
Can weld neck flanges be bored to our pipe schedule?
Yes. Include the pipe schedule or wall thickness and the flange bore will be matched to it.
Do you supply duplex and stainless flanges?
Yes, including ASTM A182 F304, F316 and F51 duplex.
