1. Light weight: The density of stamping elbow fittings is 0.89-0.91g/cm, which is only one-tenth of that of steel pipes. And because of its light weight, it can greatly reduce the transportation cost and the construction intensity of installation.

　　2. Good corrosion resistance: Except for a few hydrogenating agents, stamping elbow fittings can withstand the erosion of a variety of chemical media, have excellent acid resistance, alkali resistance, corrosion resistance, will not rust, will not corrode, and will not breed Bacteria, no electrochemical corrosion.

　　3. Good thermal insulation: Due to the low thermal conductivity of stamped elbow pipe fittings, the thermal conductivity at 20 degrees Celsius is 0.21-0.24W/mk, which is much smaller than steel pipe (43-52W/mk) and purple steel pipe (333W/mk). Therefore, the PP-R pipe has good thermal insulation.

　　4, good heat resistance: When the working water temperature of the stamping elbow pipe is 70 degrees, the softening temperature is 140 degrees.

　　5. High impact resistance: The unique impact strength performance of stamping elbow fittings has been significantly improved compared to other solid-wall pipes, and its ring stiffness is equivalent to 1.3 times that of real-wall pipes.

　　6. Hygienic and non-toxic: The stamping elbow pipe fitting material is completely composed of carbon and hydrogen without any toxic heavy metal salt stabilizer. The hygienic performance of the material has been tested by the national authority.

　　7. Long service life: Under the rated temperature and pressure, the service life of stamping elbow pipe fittings can reach more than 50 years. It has anti-ultraviolet and radiation protection, so that the product will never fade.
