Spiral Wound Gasket Pipe Unions resist temperatures up to 1,850°F.

Press Release Summary:



Able to be supplied to meet such standards as MSS-SP-83 and ASME B16.20, spiral wound gasket unions provide Class 3000 Service. Seal is formed with replaceable spiral wound gaskets without need of ground joint, and flat face design provides turbulence-free fit across seats. Graphite spiral wound gasket union withstands up to 850°F for hydrocarbon, superheated steam service, and more, while silicate spiral wound gasket union resists up to 1,850°F for superheated and chemical service.

HART Industrial spiral wound gasket unions are engineered to provide Class 3000 Service in extreme temperature and environmental conditions.  Operational conditions such as temperature, pressure, and media will dictate selection of the proper spiral wound gasket for your application.



Unions containing spiral wound gaskets can be supplied to meet national standards such as MSS-SP-83 and ASME B16.20.  The pipe union design is similar in principle to flange joints, but outperforms the difficulties associated with standard "ground-joint" pipe unions.  This is accomplished by forming the seal with replaceable spiral wound gaskets without the need of a ground joint (ball & cone).  Our flat face design provide turbulence-free fit across seats.  This design is ideal where piping requirements dictate the necessity of having a flat face seal to make and break the pipe line.



All HART Unions are Made in the USA!
