Polyurethane foam insulation pipeline
Coated steel pipe
Polyurethane foam insulation pipe is combined of high functionality polyether polyols, and formed after the chemical reaction.
Composition of the insulation pipe:
1. Steel pipe.
2. Polyurethane insulation.
3. High-density polyethylene
Application: Widely used in the urban centralized heat supply, warm room, coal, petroleum, chemical and other industries’ anti-corrosion insulation work.
Medium temperature 50-140centigrade
Working pressure < 1.6Mpa
Working lifetime 30-50years
Feature: Light Weight, High strength, thermal insulation, sound insulation, fire retardant, cold resistance, anti corrosion, non water absorbent, easy installed, keep the temperature
Technology: 1. Advanced Corona treatment. 2. Impeller blasting. 3. Leakage alarm line
Insulation pipe Standards CJ/T114-2000, CJ/T155-2001, EN253: 2003,
Advantages of the fireproof underground insulation pipe
1. Good insulation properties, low heat loss (the 25% of traditional pipes),
2. Energy saving
3. Waterproof and corrosion resistance
4. No trench, be directly buried in ground or water
