Leakproof sealant

Pressure Sealing refers to a method of stopping leaks in pressure管道s and containers with internal stored or transported media, which may occur due to corrosion, perforation, dripping, or human damage, by sealing while the medium is in motion without stopping the flow or emptying the tank. This process often involves operations that can produce sparks, such as electric welding or electric sanding, as the term "pressure sealing" does not imply a fire-free approach. However, during actual sealing, flammable and explosive media may be present, which must not produce any sparks. Therefore, domestically, pressure sealing has generally been renamed to "fire-free pressure sealing" to more clearly explain the industry's essence. Despite this, people often simplify it to "pressure sealing," but today, "pressure sealing" is widely understood to mean "fire-free pressure sealing." Since the pressure sealing industry lacks standardization, there are various names for it. Many people believe that pressure sealing is an injection-sealing method, but in reality, injection-sealing is just one technical process within pressure sealing technology. Injection-sealing is limited to straight pipes and is ineffective on fittings like tees, elbows, reducers, flanges, and large containers, where it cannot be applied.
