Products Details

The parts of high temperature flanges often need to be sealed at high temperature. If there is no good sealant for additional sealing in a separate pressure area, the pressure will cause inaccuracy or deformation of the production, that is to say, the pressure in the separate pressure area will be Leakage occurred underneath and required unplanned repair. The best application in the field of high-temperature flat sealing is Bocus high-temperature sealant. Its special formula makes it inert in standard applications of steam, gas turbines and high-temperature flanges, so it can withstand hot air, steam, water, and light fuel. Oil and lubricants are resistant to crude oil and natural gas. It is a one-component, paste-like sealant, industrial use, high-quality sealing mixture, suitable for working conditions that require high temperature and pressure on smooth and flat sealing surfaces (butt joints). Use a plaster knife or rubber spatula to spread on a dry surface. Since the sealing product will not solidify, but its consistency will change slightly to maintain flexibility and elasticity, so there is no time requirement in use, and it can be put into operation immediately after the construction is completed, without waiting.
