In recent years, with the accelerated development of electric power construction in China and the continuous promotion of new technologies and new materials, seamless elbows have been applied to dozens of new power plant projects in China. The following editor introduces you to the relevant knowledge of seamless elbow standard. Features of seamless elbow: Seamless elbows have the following advantages: hygienic, non-toxic, light weight, good heat resistance, good corrosion resistance, good thermal insulation, good impact resistance, and long service life 1. Hygienic and non-toxic: the material is completely composed of carbon and hydrogen, and no toxic heavy metal salt stabilizer is added. The hygienic performance of the material has passed the inspection of the national authority. 2. Light weight: The density of stamping elbow is 0.89-0.91g / cm, which is only one tenth of the steel pipe. Due to its light weight, it can greatly reduce the transportation cost and the construction intensity of the installation. 3. Good heat resistance: when the working water temperature is 70 degrees, the softening temperature is 140 degrees. 4. Good corrosion resistance: In addition to a few hydrogenating agents, it can resist the erosion of various chemical media, has excellent acid resistance, alkali resistance, corrosion resistance, no rust, no corrosion, no breeding bacteria, no electricity Chemical corrosion. 5. Good thermal insulation: due to the low thermal conductivity of the material, the thermal conductivity at 20 degrees Celsius is 0.21-0.24W / mk, which is much smaller than the steel pipe (43-52W / mk) and purple steel pipe (333W / mk), so PP-R The tube has good thermal insulation. 6. High impact resistance: Because of its unique impact strength performance has been significantly improved compared to other solid wall pipes, its ring stiffness is equivalent to 1.3 times that of solid walls. 7. Long service life: Under the rated service temperature and pressure, the service life of the pipe reaches more than 50 years. It has anti-ultraviolet and anti-radiation, so that the product will never fade.
