The seven advantages of stamping elbow:
The first, light weight, stamping elbow density of 0.89 0.91 g/cm, is only one over ten of the steel pipe. And because the light weight, can industry greatly reduce the transportation cost and installation of construction strength.
The second, good corrosion resistance, stamping elbow with a few hydrogenation agent, resistant to various chemical media, excellent acid resistance, alkali resistance, corrosion resistance, will not rust, corrosion will not, will not breed bacteria, no electrochemical corrosion.
Third, good heat preservation, as a result of the stamping elbow materials, low thermal conductivity, the thermal conductivity of 20 degrees Celsius 0.21 0.24 W/mk, than steel pipe (43 to 52 W/mk), purple steel pipe (333 W/mk), so the pp-r pipe heat preservation is good.
Fourth, heat-resisting performance is good: stamping elbow working temperature is 70 degrees, softening temperature is 140 degrees.
Fifth, high impact, because the impact strength of the stamping elbow unique performance than other solid wall pipe have markedly improved, the ring stiffness is equivalent to 1.3 times that of the solid wall.
Sixth, health, non-toxic: stamping elbow materials completely consists of two elements carbon, hydrogen, did not add any toxic heavy metal salt stabilizers, material of health has been through the national authoritative department detection performance.
Seventh, long service life: stamping elbow under the rated temperature and pressure, the service life of up to 50 years, has the uv protection, radiation protection, make the product that never fade.
