In recent years, with the continuous development of petrochemical and shale gas, new energy is also in coutinuous development. The market demand and development of hydrogen energy is also increasing, posing many challenges to our transportation and development processes. As an indispensable component in transportation and driving equipment, sealing components play an important role in ensuring the safety and stability of the equipment. The working conditions of hydrogen energy compression transportation equipment are extremely harsh. Nowadays, seals composed of fluororubber elastomers, modified polytetrafluoroethylene, and rectangular backup rings made of polyetheretherketone are commonly used in the market. This sealing component has low flow rate and high failure rate in practical applications under hydrogen energy sealing conditions.

JST Seals has developed multiple solutions, developing and designing hydrogen seals through internal and external testing, suitable for new hydrogen compression equipment, especially equipment related to hydrogen compression and transportation; Hydrogen seals are developed to solve environmental problems Application of hydrogen compression and transportation under high temperature and high pressure conditions of 135℃ (excluding friction heat) and 45MPa pressure.

(1) The L-shaped retaining ring can not only fix the modified polytetrafluoroethylene slip ring, but also prevent the axial extrusion of the fluororubber elastomer. Moreover, when the reciprocating speed is fast, it can also play a guiding role and improve the sealing life;

(2) A new type of elastomer material has been developed, which can withstand high temperatures and gas explosions and continuously provide elastic sealing;

(3) The slip ring material is modified polytetrafluoroethylene material, which is resistant to high temperature and wear, and has good sealing performance and service life.
