Haff sealing rubber ring plays an important role in pipeline connection and repair

Haff sealing rubber ring plays a vital role in pipeline connection and repair. They are mainly used for the socket connection of pipes, which is a common pipe connection method used to connect pipes with other fittings or valves. In addition, Haff sealing rings also play a key role in pipeline repair, especially when pipeline leaks need to be quickly repaired. These aprels can be wrapped directly at the leak point and sealed by squeezing the pipe wall.

The water diverting clip gasket is a sealing device used in piping systems

The water diverting clamp gasket is a sealing device used in the pipeline system, and its main function is to prevent the leakage of liquid or gas inside the pipeline. It is usually made of rubber, plastic and other materials, with good sealing and corrosion resistance. During use, the water diverting clip gasket needs to be tightly attached to the inner wall of the pipeline to ensure the sealing effect. When the pipeline leaks, the water distribution clamp gasket can block the leak in time to avoid further loss of liquid or gas.

Sealing rubber ring is a kind of rubber products used for sealing

Sealing rubber ring is a kind of rubber product used for sealing, which is widely used in various machinery to prevent liquid or gas leakage. According to the different materials, the sealing rubber ring can be divided into fluorine rubber, butyl rubber, silicone, ethylene propylene rubber, double fluorine rubber and so on. These materials have good high temperature resistance, high pressure resistance, chemical corrosion resistance and other properties, but also have poor elasticity, easy aging and other shortcomings. The use of sealing rubber ring pressure range of 10MPa (hydraulic), 1MPa (pneumatic) and 16MPa (static seal) Ding Qing rubber and gasoline.

Thermal pipeline polyurethane insulation pipe

The polyurethane insulation pipe wall is smooth, the drainage performance is good, the fluid resistance is small, and the scale is not the big advantage compared to other pipelines, which can greatly reduce the loss. At the same time, the linear expansion coefficient of large-diameter thermal insulation steel pipe is very small, which makes it very advantageous as the main water pipe, which greatly overcomes the defects of other plastics and ordinary pipes with large linear expansion coefficient. Large diameter insulation steel pipe is the traditional steel pipe, galvanized pipe upgrade type of cost-effective products. It has comprehensive characteristics, that is, high strength, high elongation, good low-temperature brittleness, small expansion coefficient, and plastic pipe corrosion resistance, wear resistance, low fluid resistance and other advantages. The mature technology of anti-corrosion and thermal insulation steel pipe belongs to a new type of water supply and drainage, anti-corrosion green large-diameter pipe, which is more and more widely adopted by various industries in China. In order to reduce the heat dissipation of the pipeline to the soil, the thermal insulation composite layer is added to the outside of the pipeline. The commonly used thermal insulation material is rigid polyurethane foam, and the applicable temperature is -185~120 ℃. This material is soft and soft. In order to improve its strength, a high-density polyethylene layer is added to the outside of the insulation layer to form a composite structure to prevent groundwater from penetrating into the insulation layer. High-pressure polyurethane foaming equipment is used to carry out shot blasting derusting treatment on the outer surface of the steel pipe and corona treatment on the inner surface of the outer protection pipe to improve the bonding performance of the insulation pipe. Insulation layer material for the density of 60kg/m3 to 80kg/m3 of rigid polyurethane foam, fully filled with the gap between the steel pipe and the casing, and has a certain bonding strength, so that the steel pipe, the outer casing and the insulation layer between the three to form a solid whole. Polyurethane foam has good mechanical properties and thermal insulation properties, usually temperature resistance of 120 ℃, by modification or combination with other insulation materials can be temperature resistance of 180 ℃.

Material of polyurethane directly buried insulation pipe for district heating

Polyurethane directly buried thermal insulation pipe for heating is a combination of steel pipe for conveying medium, anti-corrosion outer steel pipe and rock wool filled between steel pipe and outer steel pipe. It can also be compounded by graphite, silicon calcium tile shell and polyurethane foam filled. Steel casing (steel casing) burying technology is a new technology of waterproof, leak-proof, anti-seepage, anti-pressure and fully enclosed burying. It is a major breakthrough in the use of direct burying technology in areas with high groundwater level. The primary problem of the protection pipe of the directly buried pipeline is the reliability of tight waterproofing. In addition, it must have good mechanical strength. The steel casing adopts welding connection due to high strength, and the reliability of waterproof sealing performance is very high. In addition, its high temperature resistance is also unmatched by other external protection pipes. In areas with high groundwater level, in order to ensure that the groundwater does not affect the normal operation of the directly buried steam pipeline, the outer protective layer adopts a solid and closed steel pipe shell. Insulation pipeline is widely used in liquid, gas pipe network, chemical pipeline insulation engineering petroleum, chemical, central heating heating network, central air conditioning ventilation pipeline, municipal engineering, etc. High temperature prefabricated direct buried insulation pipe is a kind of good insulation performance, plus safe and reliable, low cost of the project buried prefabricated insulation pipe. It effectively solves the problems of insulation, sliding lubrication and waterproof of exposed pipe ends of prefabricated directly buried insulation pipes for high temperature transmission of 130 ℃-600 ℃ in urban central heating. High temperature prefabricated directly buried insulation pipe not only has the advanced technology and practical performance which is incomparable to the traditional trench and overhead laying pipeline, but also has significant social and economic benefits, which is also a powerful measure for heating energy saving.
