End Fitting Specification
- BS4825 Pt 3
- ASME-BPE-a
- Others to Special Order
Temperature and Pressure Ratings
For Standard Clamp and Standard (EPDM) Gasket
- Pressures up to 16 Bar (230 psi)
- Temperatures up to 120˚C (250˚F)
- Higher Pressures and Temperatures with Special Clamps and Gaskets.
End Fitting Materials
- Fittings in Grade AISI 316L = EN 1.4404 = BS 316 S11
- Internal Bore average 15µin Ra, Electropolished if required
- Ferrules, most in Grade 304 SS, some sizes in Grade 316L SS
Outlet Diameters
The outlet diameters as listed are in accordance with BS4825. The ASME specification, however, requires these diameters to be 0.005” (0.125mm) less in each case. An Outlet Diameter tolerance of +0.000 -0.005” has therefore been applied, so that the same fitting satisfies requirements of both specifications.
