High Temperature Sealing Wax for Industrial Equipment Flange Sealing (HT-180 Equivalent)
High Temperature Sealing Wax is a heat‑resistant formulated sealing wax as direct replacement for HT‑180. After melting and solidifying inside flange gaps, it forms a rigid heat‑stable sealing layer. This wax blocks gas and medium leakage at flange joints of high‑temperature industrial equipment, suitable for flange sealing during equipment commissioning, pressure testing and temporary service.
Product Overview High Temperature Sealing Wax (HT‑180 Equivalent) is a specially engineered heat‑resistant sealing wax dedicated to industrial equipment flange applications. In molten condition, the wax flows into narrow flange clearances. After cooling and curing, it builds a rigid, heat‑resistant sealing barrier within flange gaps. It effectively inhibits gas and fluid leakage from flange joints under moderately high‑temperature working environments. The wax maintains stable sealing capacity during equipment pressure‑testing, trial run and temporary operation. It is widely adopted in chemical, petrochemical and thermal power facilities for flange gap sealing work.
Key Features ‑ Designed high‑temperature resistance for flange joint sealing under elevated service temperature ‑ Good molten flowability to penetrate narrow irregular gaps between flange mating surfaces ‑ Forms rigid solid seal after cooling to suppress gas and fluid leakage ‑ Stable sealing performance after repeated short‑term thermal cycling ‑ Compatible with carbon‑steel and alloy flange metal substrates
Typical Technical Properties ‑ Chemical Type: Modified high‑melting hydrocarbon‑based sealing wax ‑ Appearance: Dark brown to black solid blocks or pastilles ‑ Melting Range: Refer to TDS ‑ Softening Point: Refer to TDS ‑ Sealing Pressure Resistance: Refer to TDS
Applications ‑ Petrochemical plant: Temporary flange sealing for process pipeline equipment ‑ Thermal power facility: Flange gap sealing during equipment pressure‑testing procedure ‑ Industrial machinery: Auxiliary sealing for high‑temperature reactor flange joints ‑ Equipment maintenance: On‑site flange sealing for overhaul and commissioning jobs
Processing Recommendation Adopt controlled heating for wax melting and avoid local over‑heating and carbonization. Thoroughly clean flange mating surfaces before wax filling. Allow sufficient cooling and complete solidification of sealing wax before conducting pressure testing. Run on‑site trial sealing to verify performance prior to large‑scale maintenance operations.
Storage & Handling Store in cool, dry and ventilated warehouse, keep away from intense heat sources and open flame. Reseal packaging after opening. Wear heat‑resistant gloves when handling hot molten wax and solid wax stock.
