- Flange joint is a kind of appliance used for flange sealing.
- For bolted flange joints that have been working at high temperatures for a long time, due to the creep relaxation of the gaskets and bolts, the residual stress on the gaskets is gradually reduced, the reliability of the sealing of the flanged joints is gradually reduced, and eventually the leakage fails. To solve the problem of sealing flange joints, high temperature sealants can be used for sealing. It is suitable for working conditions that require high temperature and pressure on smooth and flat sealing surfaces (butt joints). Particularly suitable for sealing metal joints: steam turbines and gas turbines, compressors, pumps, housings, flange joints, etc. Resistance to hot steam, gas, hot and cold water up to 900 , light fuel oil, lubricant, crude oil and natural gas. Excellent adhesion at the sealing surfaces and joints ensures pressures up to 250 bar (255kg / cm2). Applicable to: equipment and pressure vessel flanges, bearing races, bolt flanges, bearing rings, looper flanges, support washers, sealing washers, manhole flanges, flat flanges, butt-welded flanges.
