Heat resistance of carbon steel slip on flange

　　2. Long service life: Under rated operating temperature and pressure, the service life of carbon steel slip on flange is over 50 years, with anti-ultraviolet, anti-radiation, so that the product will never fade.

　　3. Good corrosion resistance: Except a few hydrogenating agents,carbon steel slip on flange can resist the corrosion of various chemical mediums. The carbon steel slip on flange has excellent acid resistance, alkali resistance, corrosion resistance, no rust, no corrosion, no bacteria, no electrochemical corrosion.

　　4. Good thermal insulation: PP-R pipe has good thermal insulation because of its low thermal conductivity, the thermal conductivity of 20 degrees Celsius is 0.21-0.24W/mk, which is much smaller than that of steel pipe (43-52W/mk) and purple steel pipe (333W/mk).
