Heat resistance of carbon steel weld neck flanges

　　High impact resistance: Because the carbon steel weld neck flanges unique impact strength function has been significantly improved compared with other solid-walled pipes, its ring stiffness is 1.3 times that of solid-walled pipes.

　　Long service life: under the rated service temperature and pressure, the service life of carbon steel weld neck flanges can reach more than 50 years, with anti-ultraviolet, anti-radiation, so that the product will never fade.

　　Good corrosion resistance: Except for a few hydrides, it can resist the corrosion of various chemical media. The ANSI B16.5 Class 600 Forged Carbon Steel Weld Neck Flanges has excellent acid resistance, alkali resistance, corrosion resistance, no rust, no corrosion, no bacteria, no electrochemical erosion.

　　Good thermal insulation: because the material of carbon steel weld neck flanges thermal conductivity is low, 20 degrees Celsius thermal conductivity is 0.21-0.24 W/mk, than steel pipes (43-52W/mk), purple steel pipes (333W/mk) much smaller, so PP-R pipe insulation is good.
