Purchase description
CLASS 1500 STUD BOLTS, 10"", ASTM A193 B7 / A194 2H, ASME B16.5
Available materials: ASTM A193 B7 / A194 2H, ASTM A320 L7 / A194 7, ASTM A193 B8M / A194 8M, Hot-dip galvanised B7.
Notes
- Lengths are in millimetres for a 2 mm raised face (Class 150 and 300) or 7 mm raised face (Class 600 and above), and for ring-joint flanges with the standard ring.
- Stud lengths are those tabulated in ASME B16.5 and do not include the height of the points.
- Different lengths are needed for lap joint flanges, for spectacle blinds or orifice plates in the joint, and when bolt tensioners are used.

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.
