Pb pipe (Polybutene) is a polymer inert polymer. It was born in the 1970s. PB resin is a polymer composite synthesized from butene-1. It has high temperature resistance and durability. Chemical stability and plasticity, odorless, non-toxic, odorless, temperature range -30 ° C to 100 ° C, with cold resistance, heat resistance, pressure resistance, no rust, no corrosion, no scaling, long life (reachable 50-100 years), and has long-term aging resistance, is one of the most advanced chemical materials in the world. It has been widely used in many countries in the world. There is a reputation for "gold in plastics". Characteristics 1. Light weight, good flexibility, PB pipe weight is 1/20 of galvanized steel pipe, easy to handle, soft material, minimum bending radius is 6D (D: pipe outer diameter) 2. Durable, non-toxic and harmless: Because it is a high-density polymer, the molecular structure is stable, the service life can reach 50-100 years, and it is non-toxic and harmless, and no chemical reaction occurs. 3. Anti-ultraviolet, anti-corrosion: PB tube is resistant to ultraviolet rays and microorganisms, and can make the water stored therein not deteriorate for a long time. 4. Good resistance to freezing and heat resistance: in the case of -20 °C, it has good low-temperature impact resistance, the pipe will not freeze and crack, after thawing, the pipe can be restored to the original, and can withstand high temperatures below 100 °C. 5. The pipe wall is smooth and non-fouling: compared with the galvanized pipe, the water flow can be increased by 30%. 6. The thermal expansion is good, and the connection method is advanced: the thermal expansion of the PB pipe is about 1/60 of the metal pipe, and the expansion coefficient is similar to that of the concrete. The connection method is an integrated hot-melt connection, so when the battery is buried, the movement of the pipe and the leakage at the joint due to temperature changes and water hammer can be avoided. 7. Energy saving: When the PB pipe is used for low-temperature ground radiant heating, energy can be saved by 30%. 8. Easy to repair and reform: When the PB pipe is buried, it will not be bonded to concrete. application 1. Water supply (sanitary pipe) and hot water pipe: In terms of tap water and hot water pipes, PB pipe is recognized as a non-toxic, odorless and best durable pipe material. 2. Heating pipe: Because of its good insulation, construction and permanent durability, it is most suitable for the connection of the building and the underfloor heating pipe system. 3. Industrial pipe for air conditioning: Because of its corrosion resistance (acid and alkali resistance), it is non-toxic and tasteless. It is the best pipe for chemical engineering, food processing engineering, general hospital and industrial water. Due to its high compressive strength, it is most suitable for use in air conditioning duct systems. 4. Agricultural and horticultural tubes: Because of their corrosion resistance, softness and UV blocking properties, they are used for irrigation, golf field sprinklers, underground heating of farms, and spraying of sprays. 5. Snow removal pipe: It has a permanent life and strong impact resistance, and is especially suitable for snow removal pipes for roads, parking lots and playgrounds. Engage in good impact pipe. 6. Hot spring tube: It has outstanding heat and pressure resistance and will not produce rust and scale. It has an unparalleled effect as a hot spring tube. 7. Pipes for automatic sprinkler systems for fire protection: For the first time in non-metallic pipes, they have passed the UL specification of the United States and have been approved by FM. They are widely used as pipes for automatic sprinkler systems in developed countries.
