One is buried pipe insulation and outer tube filled with polyurethane foam insulation between the pipe and the outer pipe by pipe transport medium and high density polyethylene closely together . Just after the steel rust corrosion sets in the polyethylene casing, intermediate injected polyurethane foam , making it fully fills the gap between the casing pipe and polyethylene , and finally to pipe , casing, forming a solid insulation overall , to corrosion insulation effect.
Pipe Inspection - rust corrosion - wear tube forming - head repair - product testing - finished stacking
Pipe buffer platform , dial pipe unit , transmission line , pipe preheating furnace , shot blasting machine host test drive turntable and substandard steel return line , fast forward roller set , tractor, wearing a tube machinery, high pressure foaming machines , repair platform faster wheel inspection platforms.
Product Features :
Buried prefabricated pipe insulation than traditional types of pipe insulation has a very distinct advantages :
1 , good insulation properties, heat loss is only 25 % of the traditional pipe insulation , long-term operation can save a lot of energy , significantly reducing energy costs.
2 , has a strong waterproof and corrosion resistance , without attached trench can be directly buried in the ground or water , construction easily and quickly , and lower total cost .
3 , at low temperatures also have good corrosion resistance and impact resistance, and can be directly buried in permafrost .
4 , life of up to 30-50 years , proper installation and use can make the pipe network maintenance
