1. Light weight: the density of the stamped elbow pipe is 0.89-0.91g/cm, which is only one tenth of the steel pipe.And because of the light weight, can greatly reduce the industry transportation costs and installation of construction intensity.

2. Good corrosion resistance: stamping elbow fittings in addition to a few hydrogenating agents, can withstand the erosion of a variety of chemical media, with excellent acid resistance, alkali resistance, corrosion resistance, no rust, no corrosion, no bacteria, no electrochemical corrosion.

3. Good thermal insulation: due to the low thermal conductivity of the material of the stamped elbow fittings, the thermal conductivity of 20 degrees Celsius is 0.21-0.24W/ MK, much smaller than the steel pipe (43-52W/ MK), purple steel pipe (333W/ MK), so the PP-R pipe has good thermal insulation.

4. Good heat resistance: when the working water temperature of the punching elbow pipe is 70 degrees, the softening temperature is 140 degrees.

5. High impact resistance: due to the unique impact strength performance of the stamped elbow pipe, its ring stiffness is equivalent to 1.3 times that of the solid wall.

6. Health and non-toxic: stamping elbow pipe fitting material is completely composed of carbon and hydrogen without adding any toxic heavy metal salt stabilizer.

7. Long service life: the stamped elbow pipe has anti-ultraviolet and anti-radiation under rated service temperature and pressure, so that the product will never fade.
