Steel Pipe Insulation

components of the insulated duct:

1.inner steel pipe

2.polyurethane insulation layer

3.outer HDPE protection pipe

Application of the steel pipe insulation:

1.district heating and cooling

2.for hot water and chilled water insulation

3.crude oil and gas insulation

4.chemical and other anti-corrosion insulation field

Medium temperature:50-140centigrade

Working pressure:≤2.5MPa

Working lifetime:30-50years

PU foam density:≥60kg/m³

Laying method:

1.direct bury

2.built on stilts

3.trench

Technology used:

1.Advanced Corona treatment

2.Impeller blasting

3. Leakage alarm line

Standards:GB/T29047-2012,CJ/T114,EN253,EN448,EN489

Advantages of the steel pipe insulation:

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
