Product Description:


1.inner work steel

Seamless steel pipe for steam

Impeller blasting and paint before insulation

Standard of GB/T9823-1988 and level Sa2.5

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
