A bleed ring is a ring section with one or more radial pipe connections designed to fit between standard flanges within the bolt circle, using conventional gasket material. The ring normally comes with a 1/2 inch socket weld or 3/4 inch tapped for connecting with valves and instruments. The face of the ring can also be made to matched with any flange type, and has different sizes based on the ASME flange rating of the process piping.

Bleed Rings 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, this allows you to reduce and dispose of the pressure for your valve before you remove the flange. This is usually done with a replacement for a leaky valve.

The bleed ring can come in any material or size, and is designed for connecting valves and instruments. The face of the bleed ring can be manufactured to match with any flange type. The standard sizes for a bleed ring are NPS 1 to NPS 24 and ASME Pressure Classes 150 through 1500. It comes in many different materials such as carbon steel, stainless steel etc.

Drip Rings, or Flushing Rings, are used in the oil or gas line. They are coupled between two seals.

The Drip Ring is circular, as a ring, with one or two holes. They may have one or two branches, based the usage that is made for.

In the branch’s hole can be inserted instruments: pressure gauge, thermowell or it can be free to allow the drainage of condensate.

In correspondence to each hole the Drip Ring can be welded to a Weldoflange or a branch connector. 

The flushing rings are used for flushing solution combined with diaphragm seals. This type of flushing flange or ring is clamped between process nozzle and diaphragm seal. The reducer flange is used to mount a larger diaphragm seal to a smaller process connection. This type of reducer flange is clamped between process nozzle and diaphragm seal.

Diaphragm Seal Accessories are carefully designed to optimise the use of the Diaphragm Seal in your process conditions, or to ease the installation and protect it against damaging during installation.
