Notes
- All dimensions are in millimetres.
- Flange outside diameter, bolt circle and drilling are common to all EN 1092-1 flange types of the same DN and PN, so flanges of different types mate with each other.
- Bolt sizes are metric (ISO). Bolt holes are 2–6 mm larger than the bolt, as tabulated.
- Up to DN 150, PN10 flanges use the PN16 dimensions; from DN 200 the PN10 drilling differs. Flange thickness depends on the flange type — confirm against the standard for your type.

Frequently asked questions
What are the main types of pipe flanges?
Weld neck (WN), slip-on (SO), blind (BL), socket weld (SW), threaded (THD), lap joint (LJ) and plate flanges. Special types include orifice, long weld neck, reducing flanges and spectacle blinds.
When should I use a weld neck flange instead of a slip-on?
Use weld neck flanges for high pressure, high or cycling temperature, and lines with vibration or fatigue loading. The tapered hub and full-penetration butt weld spread stress smoothly. Slip-on flanges are cheaper and easier to align, but their fatigue life is roughly one third of a WN.
What does Class 150, 300 or 600 mean on a flange?
The ASME class is a pressure-rating designation, not a pressure in psi. The allowable pressure depends on the material group and temperature. A Class 150 A105 flange is rated 19.6 bar at 38 °C but 13.8 bar at 200 °C.
Is a 150# flange rated for 150 psi?
No. A Class 150 carbon-steel flange is rated about 285 psi (19.6 bar) at ambient temperature, and about 170 psi (11.7 bar) at 260 °C. The "150" is a class number.
