Flush Ring

Flush Ring

Flushing Rings are designed to be sandwitched between the process flange and the disphragm seal in order to avoid the formation of deposits or blockages by the process conditions and the geometry of the connection which could make the medium into deposites or blockages.

Bleed Ring

Bleed Ring

Bleed Rings is similar to a Spacer Ring, but it doesn’t have a handle. Bleed Rings have one or more radial pipe connections and are fitted inside the circular bolts between the standard flanges that connect valves or instruments. Used to relieve pressure or drain fluids.

Flush Ring Mounting

Flush Ring · Drip Ring · Bleed Ring · Diaphragm Seal Accessories

Flush Rings also known as Drip Ring or Bleed Ring or Diaphragm Seal Accessories supplied by Siddhagiri Metals and Tubes, have the same diameter as the flanges, bringing the valves clear of the flanges and eliminating the need for flushing port extension adapters. Drip Rings are held in place by through-bolts or captive studs, making them easy to install. The captive stud versions have the added advantage that the drip ring stays in place if either the process valve side or the diaphragm side requires removal. Bleed Rings also have the benefit of allowing for size reduction. Siddhagiri Metals and Tubes produces a variety of tapered bore Flush Ring or Drip Ring or Bleed Ring, typically with a 2” process-side flange and a 3” diaphragm-side flange to allow use of larger diaphragms for improved measurement accuracy without having to employ unnecessarily large and heavy valves. Material collected in front of diaphragm can be flushed out through the flushing ports, or the pressure volume can be vented. Various nominal sizes and forms allow adaption to the respective process flange. Flushing Rings also reffered to as drip rings, are used between an isolation valve and the diaphragm seal of a pressure transmitter. Flush rings are used for diaphragm seals in order to prevent clogging of the instrument connection. Flushing Ring also known as calibration ring, as it is used to apply known pressure and calibrate transmitter against known pressure. Flushing rings are simply mounted between the flanged process connection and the diaphragm seal. The two flushing ports allow washing out of particles accumulated in front of the membrane and the pressure space can be vented or drained according to requirement. Side ports on the rings allow media to be injected/ejected so that the diaphragm can be flushed free of deposits that affect transmitter measurement accuracy.

Difference Between Drip Ring and Bleed Ring

There is not much difference between a Bleed Ring and a Drip Ring. Majority of companies call them bleed rings because they allow bleeding pressure or mount pressure gauges or other sensors into a piping system. Drip 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. Bleed 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 Drip 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. Drip Rings 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 Drip Ring can be manufactured to match with any flange type. The standard sizes for a Bleed Ring or Drip Ring are NPS 1 to NPS 24 and ASME Pressure Classes 150 through 1500.
