In terms of price, pb pipe has significant economic benefits: low cost, low investment, compared with metal pipes, can reduce engineering investment by about 1/3. Make pb tube become the material of choice of project. So where is the pb tube generally used? What are the pb tube specifications ? Next Xiaobian will introduce it to everyone.
What are the characteristics of pb tube?
1. Light weight, good flexibility, PB tube weight is 1/20 of galvanized steel pipe, easy to handle, soft material, minimum bending radius is 6D (D: tube outer diameter)
2. Durability is good, 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 and anti-corrosion: The PB tube is resistant to UV rays and microorganisms, and can make the stored water not deteriorate for a long time.
4. Good resistance to freezing and heat resistance: Under the condition of -20°C, it has good low temperature impact resistance, and 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. Smooth wall, no scaling: Compared with galvanized pipes, the water flow can be increased by 30%.
6. Good thermal expansion and advanced connection methods: The thermal expansion of the PB tube is approximately 1/60 of that of the metal tube, and its expansion coefficient is similar to concrete. The connection method is an integrated hot melt connection, so that when the pipe is buried, the movement of the pipe and the leakage at the connection due to the temperature change and the water hammer phenomenon can be avoided.
[pb tube application areas]
1. Water supply (sanitary pipes) and hot water pipes: In terms of tap water and hot water pipes, PB pipes are recognized as non-toxic, odorless, and optimally durable pipe materials.
2. Heating pipe: Due to its good insulation, construction and permanent durability, it is most suitable for the connection of the building and underfloor heating piping system.
3. Industrial-use air-conditioning pipe: Because of its strong corrosion resistance (resistance to acid and alkali salt), non-toxic and tasteless, it is the best pipe for chemical engineering, food processing engineering, general hospitals, industrial water and so on. Due to its high compressive strength, it is most suitable for use in air conditioning duct systems.
4. Agricultural and horticultural tubes: Used for irrigation, sprinklers in golf courses, underground heating for farms, and piping for spraying because of their strong corrosion resistance, softness, and UV-blocking properties.
5. Snow removal pipe: With permanent life and strong impact resistance, it is especially suitable for snow removal pipes for roads, parking lots and playgrounds. Engage in good impact pipe.
6. Hot spring tube: outstanding heat and pressure resistance, no rust and scale, as a hot spring tube with unparalleled effect.
What are the pb tube specifications?
    For the specifications of the PB tube, it is divided into six series of S3.2, S4, S5, S6.3, S8 and S10 according to the size. Polybutylene (PB) pipe system according to the provisions of GB/T 18991-2003, according to the use of conditions selected 1,2,4,5, four application levels, see Table 2 below, each level corresponds to a specific range of applications And 50 years of service life, in practical application, should also consider 0.4MPa, 0.6MPa, 0.8MPa, 1.0MPa different design pressure. The quality of the pipe is mainly determined by the pressure capacity and wall thickness of the pipe. Tubes produced by different manufacturers have different thicknesses. Level 1 pb tube, TD °C60 use time 49 years Tmax °C80 use for 1 year, supply hot water range 60 degrees. In the medium 20oC, system pressure 16bar, medium 70oC, system pressure 10bar and medium 95oC, system pressure 6bar under three different conditions can guarantee safe and reliable operation for 50 years, safety factor 1.5.
Conclusion: After listening to the introduction of Xiao Bian, we must have a more in-depth understanding of the specifications of the PB tube . For more relevant knowledge, please continue to pay attention to this website information platform.
