Description

Siphon tube protects your pressure instrument, gauge, switch and transmitter from high temperature process fluids. Siphon tube is used to protect those directly coming in contact with high temperature process fluids or vapors. This reduces steam or other process media temperature prior to enter into the instrument.

Specifications
Connection:  1/4″ & 1/2″NPT, BSP, or BSPT
Body: stainless steel sch. 40
Type: Pig tail & U type
Pressure rating: 3,000 psi

Protection
– If pressure gauges are to be used for steam service, a siphon tube filled with water must be installed between gauge and line to prevent live steam from entering the Bourdon tube.
– A gauge cock should be installed in the pressure line. This might be the standard shut-off valve or a needle valve for throttling pressure pulses.
– If severe pulsation exists, the gauge should be protected by adding a throttling orifice
screw in the gauge socket or by addition of a pulsation damper, such as a snubber.
– A diaphragm seal should be used in applications where process media should not come in contact with gauge.
