What is the difference between CG and CGI gasket?
Style CG gaskets are suitable for use in mild to moderate service conditions. Style CGI – In addition to an outer metal ring the CGI style gasket is fitted with an inner metal ring, constraining the sealing element on both internal and external diameters.
What is BCD in gasket?
Full face gaskets are a bit more difficult to measure because there are five things that you need to verify correctly: Inside Diameter (ID), Outside Diameter (OD), Bolt Circle Diameter (BCD), bolt hole diameter and the number of total bolt holes.
What is a flexitallic gasket?
The Flexitallic Spiral Wound Gasket is the precision-engineered solution for flanged joints, heat exchangers, boiler handholes, manholes and other high temperature, high pressure applications—providing resistance to virtually every known corrosive and toxic element.
What is CGI gasket?
The CGI spiral wound is standard spiral wound gasket per ASME B16. 20 . The Style CGI is for use with flat face and raised face flanges. This gasket features increased compressive force for blow-out prevention and is specified for high pressure/temperature service or where corrosive or toxic media are present.
What is PTFE gasket?
PTFE GASKETS (TEFLON GASKETS) Teflon, a synthetic fluoropolymer with excellent dielectric properties and a low coefficient of friction, is the DuPont brand name for polytetrafluoroethylene (PTFE). Teflon gaskets provide excellent thermal insulation and resist corrosive chemicals.
How are gaskets measured?
When measuring a circular gasket, think of it as a clock. Use a tape measure or ruler and measure across the gasket from the 9:00 position to the 3:00 position. Measure the inside edges for the I.D. and the outside edges for the O.D. Next, count the number of BH (Bolt Holes) around the face of the gasket.
How do you measure a flange gasket?
To measure such circle measure from the center of one bolt directly across to the center of the other bolt. The Outside Diameter is the measurement of the outside of the Flange or Gasket. The Inside Diameter is the measurement of the inside of the hole of a Flange or Gasket.
What is Thermiculite gasket?
Thermiculite® 835 is a critical service gasket designed for use in applications involving high temperatures and/or aggressive chemical media. It is comprised of a spirally wound sealing element composed of a metal winding wire in combination with a vermiculite based filler material.
What is a Garlock gasket?
Garlock’s BLUE-GARD Style 3700 gasketing material is a compressed, non-asbestos gasket made from aramid fibers with an EPDM binder. These gaskets drastically lowers emissions levels, fluid loss, and energy consumption. The…
