The TX20.20 is a gasket composed of a metal ring having the function of “centering ring”, a support for the sealing material and an anti-vortex element in correspondence with the flanged joint.
Confined Gaskets
Standard flange gaskets
Graphite confined by synoidal edges, gives the gasket a high and fast elastic recovery, which is essential where sudden changes in pressure and temperature are expected.
The high compressibility of the graphite used allows it to be applied even on surfaces with a varied and irregular finishing range.
The metal ring makes the gasket sturdy and easy to handle.
The thermal stability of the graphite, in conjunction with the metal support, guarantees the constancy of the elastic characteristics of the TX20.20 even at high temperatures and also does not place limits on chemical compatibility with the circulating fluids.
Special gaskets
TX 20.21 and TX 20.22 gaskets, derived from TX20.20, have been designed to replace doule jacketed gaskets in particular, and non- confined spiral wound gaskets.
Properties and Applications
- The TX20.21 and TX20.22 gaskets have a seating load ‘y’ equal to 6.20 N/mm2, much lower than the metal jacketed and spiral wound gaskets ranging from 37.9 up to 68.9 N / mm2 allowing application on uneven surfaces.
- Also the factor ‘m’ equal to 2, is lower than metal jacketed and spiral wound ones, these last which is between 3.25 and 3.75.
- TX 20.21 is covered by a graphite thk. 1,6 mm while TX 20.22 is covered by graphite thk. 0,8 mm.
