Rock Wool with Aluminum Foil Steel Pipe Jacket

2.aluminium silicate fiber felt(drag reduction layer)

Be put between inner work and inorganic insulation

(to insure the steel pipe movement when expansion and contraction)

3.calcium silicate insulation material

Can be customed into glasswool,rock wool,ect

Use break strapping, and filled foam asbestos in the cracks to reduce heat lossing

4.aluminum reflector

To prevent the inorganic insulation foam from going into the insulation material

Prevent heat loss and make the steam pipe is more economic

5.polyurethane insulation layer

Good effect of heat insualtion

6.outer work steel

GB/T9711.1Spiral weld pipe or SY5292ERW pipe

7.outer anticorrosive coating

3PE anticorrosion

Usage

High temperature steam pipeline in

Urben central heating

Petroleum,chemical,power and other high temperature heat pipeline

Transmit temperature

150°C—350°C

Working pressure

<1.6Mpa steam

Buried depth

Underground 1-2m

Advantages

1. waterproof,moistureproof,leakproof,impervious

2. thermostability(high temperature resistant), high pressure resistance

3. low heat loss, heat insulation is better

4. strong anti-corrosion

5. long life,about 30-50 years

6. be directly buried in the ground
