high temperature steam pipe insulation

steam insulation pipe 1.Usage of the steam pipe:      1) urban centralized heat supply        2) warm room      3) coal mine      4) petroleum      5) chemical and other anti-corrosion insulation field   2.Medium teperature: 150-350°c 3.Working pressure: 2.5Mpa 4.Laying method:     1) direct bury     2) built on stilts     3) trench   5.Produce technical:     1)Advanced Corona treatment     2)Impeller blasting     3)Leakage alarm line 6.Advantage:     1)good insulation properties ,low heat loss (the 25% of traditional pipes),     2)energy saving     3)waterproof and corrosion resisdence     4)no trench,be directly buried in ground or water    Related pictures of the steam pipe insulation:   Diameters variation
