Function:

1. concentrated heat preservation with wind pipe:inside and outside the pipe is metal plate,level B1 insulation board is between two layer metal, moulding under special processing equipment.

2. Metal board inside and outside layer is color steel plate, galvanized plate, aluminum zinc or aluminium plate, and embossing on these metal,single face or double face.

3. The strength and insulation properties is better than all other forms of wind pipe due to it is the metal plate and the insulation board bonded into a whole on the special equipment.

4. Some parameters:

a)、Pressure resistance strength:>250KPA
b)、Thermal conductivity:≤0.017--0.022W/M.K
c)、Working pressure of wind pipe:-3000-+3000Pa
d)、Fire Protection Level:Surface is Level A1,inner insulation board is Level B1
5. Configuration of heat trasfer pipe is equilateral triangle.

application area:

Supply or return duct in textile、chemical fiber、machinery manufacturing、automobile manufacturing、hotel、shoppingmall and supermarket、purification workshop and building etc.
Production material:

External metal board:color steel plate, galvanized plate, galvanized plate etc.Internal insulation board:XPS、EPS or polyurethane.
