1. Duplex stainless steel 316L bleed ring definition
A bleed ring, vent ring, or drip ring can provide a beneficial way of draining piping, taking samples, attaching instruments or even bleeding of a valve. They can also be used with a valve and/or blind flange, which allows you to reduce and dispose of the pressure for your valve before you remove the flange.
HT pipe Bleed Rings are designed to withstand any pressure –
temperature combination that an ASME flange will withstand.

Multiple taps can be provided but must be orientated by customer.
Thickness of ring may be affected if larger taps are required.
• One coat of standard shop primer will be applied to all carbon
steel rings unless specified differently.
