ANSI Carbon Welding Neck Flange factory
Carbon welding neck flange has advantages in performance and good thermal insulation: due to its low thermal conductivity, the thermal conductivity at 20 ℃ is 0.21-0.24w/mk, which is much smaller than steel pipe (43-52w/mk) and purple steel pipe (333w/mk), so PP-R pipe has good thermal insulation.
