1.Carbon steel flange high impact resistance: due to the unique and special impact strength function than other solid wall pipe has significantly improved, its ring stiffness is commensurate with the solid wall 1.3 times.

2.Carbon steel flange use to save the life of the number of years: pipe in the quota of the use of temperature and pressure, use to save the life of more than 50 years, with uv, radiation, make the product fade.

3.Carbon steel flange corrosion resistance: in addition to a small amount of hydrogenating agent, can withstand the corrosion of a variety of chemical media, the flange has a particularly good acid resistance, alkali resistance, corrosion resistance, will not rust, will not erode, will not breed bacteria, no electrochemical erosion.

4.Carbon steel flange heating: due to the low heat transfer coefficient of the material, the heat transfer coefficient 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 heating is good.
