Clamp Ring Closure The Clamp Ring Closure
provides a quick opening
access point to pipelines
or pressure vessels, for the
installation / removal of
equipment.
The clamp ring closure is
designed in accordance
with ASME VIII Divison 1,
ASME B31.4 (Oil & Liquid
Products Code) & ASME B31.8
(Gas Pipeline Code).
The design consists of six
main components:
Hub (Pressure Retaining)
Door (Pressure Retaining)
Clamp (Pressure Retaining)
2 x vent/bleeder screws
(Pressure Retaining)
2 x operating screws
O-Ring seal (Pressure Retaining)
Features of the Clamp Ring Closure:Range from 4"ns up to to 48"ns
ANSI Class rating up to ANSI Class 600
Standard wall thickness range dependent upon ANSI Class rating
Dual pressure alert vent/bleeder system
Meets code requirements of external, visible pressure warning device
Operating screws manufactured from stainless steel 316, for corrosion resistance
Screw inserts manufactured from carbon steel & xylan coated for corrosion resistance
Temperature range up to 392°F (200°C)
Pressure retaining parts in accordance with NACE MR0175
O-Ring seal easily replaced
Suitable for both left and right hand orientation
