HTG System

TG Flange Insulation System

Description:

The  TECSON  HTG  flange  insulating  kit  is  comprised  of an insulating  gasket,insulating  sleeves,  insulating  washers and metal  backing  washers.  The  insulating  gasket  is constructed from serrated metal core ,faced with SONMAX 700, a proprie-

tary high temperature sealing material. Correct gasket location is ensured by the use of a SONMAX 700H ring, located around the periphery of the serrated metal core.

HTG  high  temperature  flange  insulation  sets  are specifically designed  to  create  a  seal  and  maintain  electrical isolation across a wide range of seating stresses and flange classes in elevated  temperature  service.  The  SONMAX  sealing material pushes the performance of the HTG insulation kit beyond the temperature  capability  of  traditional  insulation  sets  based on vermiculite  or  glass/epoxy  sealing  technology.  SONMAX is

designated as fire safe, complying with the requirements of the oil and gas industry recognized API 6FB fire tests.

dvantages:

- Operational  pressure  :  From  Full  vacuum  to  ASME  B16.5 1500lb (26.0MPa)

- Operational temperature -200°C to 500°C

- SONMAX  is  suitable  for  sealing  across  a  wide  range  of chemicals  (pH  0-14)  and  sweet  and  sour  gaseous  and  liquid

hydrocarbons.

- Standard core and washer metallurgy are NACE (MRO175) compliant.

- Dielectric Strength (ASTM D149) : 10.0 kV/mm
