We are engaged in providing RTJ Gasket, a class of energetic gasket designed for use in high-temperature and high-pressure environments. It is extremely strong mechanically or heat resistant. According to API 6A, API 17D, and ASME B16.5/B 16.20 requirements, standard size gasket is produced. To prevent flange deformation, we make sure that the hardness of the ring is always lower than the hardness of the flanges.
