Polyurethane insulation steel pipe for insulation reasons
Polyurethane insulating steel pipe exterior protection pipe is mainly made of polyethylene, so people are also accustomed to call polyethylene exterior casing.
Polyethylene outer sleeve is made of high density polyethylene material, which has high mechanical strength and excellent corrosion resistance. It can maintain the pipeline in transportation, installation and application process to prevent damage caused by external factors. The outer tube should be added with antioxidants, UV stabilizers and carbon black.
At present, polyurethane insulation pipes are mainly used as insulation pipes.
1., we can reduce the project cost. According to the calculation of relevant departments, the cost of double-control heating pipeline can generally be reduced by 25% (using FRP as maintenance layer) and 10% (using high density polyethylene as maintenance layer).
2. use polyurethane heat preservation steel pipe, low heat loss and energy saving. The thermal conductivity of polyurethane insulating pipe is much lower than that of other commonly used pipe insulating materials in the past, and the thermal insulation effect can be increased by 4-9 times.
3. polyurethane thermal insulation steel pipe corrosion resistance, good insulation function, long service life. Polyurethane heat preservation steel pipes, because the rigid polyurethane foam insulation layer is tightly bonded to the outer skin of the steel pipe, can separate the air and water from entering, and can play an excellent anti-corrosive effect.
The service life of polyurethane insulating steel pipe can reach more than 50 years, which is 3-4 times longer than that of traditional trench laying and overhead laying. Ultimately, but also the most important point: the use of polyurethane insulation steel pipe occupies less land, construction is fast, conducive to environmental maintenance. Polyurethane insulating steel pipe is directly buried underground, which greatly reduces the project area and shortens the construction period by more than 50%.
In summary, all the above-mentioned Shandong Hipper Pipe Technology Development Co., Ltd. provides, want to know more polyurethane insulation pipe manufacturers, welcome to pay attention to our website: https://www.sdhpgy.com Thank you for your support!
