High temperature prefabricated buried pipe insulation consists of four parts.

(1) Pipe work: according to the technical requirements of the transmission medium were used pipe joints, seamless steel tubes, double-sided spiral submerged arc welded steel pipe.

(2) Insulation layer: rigid polyurethane foam.

(3) Protective shell: high density polyethylene or fiberglass.

(4) Leakage alarm line: the manufacture of high temperature prefabricated buried pipe insulation, the insulation layer near the pipe, buried alarm line, once the pipeline leakage occurs somewhere through the alarm line conduction, can be a dedicated instrumentation on alarm and show the exact location and size of the level of leakage leakage, in order to notify maintenance personnel to quickly deal with a leaky pipe, heating network to ensure safe operation.

High temperature prefabricated buried pipe insulation - Advantages

1. Highly resistant to corrosion and water capacity, and lower total cost.

2. Low heat loss and save energy. Heat loss of only 25% of traditional pipe.

3. Long life.

4. Covering less fast construction are environmentally friendly.
