It is widely used in chemical companies, oil fields, gas storage, and various places where high-temperature pressure medium leakage may occur. It can effectively treat leaks in pipelines, flanges, valves, elbows, tees and other parts. The temperature range of the pluggable medium is -200 ℃ -600 ℃, suitable for the variety of medium, covering almost all kinds of acids, alkalis, salts, water, oil, gas and various chemical solvents; the upper limit of leaking gap width and upper limit of aperture: 5mm; manual High-pressure pump pressure; 62MPa (up to 76MPa) blockable medium pressure: 20MPa (up to 30MPa). According to different requirements, they are divided into ZR (heavy) and ZRI (portable). They all include: manual high-pressure pumps, high-pressure glue guns, high-pressure oil pipes, plug valves, various types of glue-injection joints and rust inhibitors, and sealants. Among them, the sealant is divided into white, blue and other colors, and the shelf life is two years.
