"High-density polyethylene outer sheath tube Buried prefabricated polyurethane foam pipe insulation" is widely used in urban central heating, cooling areas. Long-term operation can be used to transport temperature not higher than 130 ℃ hot water, hot oil, cold and other media. With insulation effect, small footprint, low construction cost, long life, easy installation features.

Buried pipe insulation pipe work by the transmission medium (core tube), polyurethane thermal insulation and outer casing of polyethylene pipe closely together. Work steel used in line with national standards or standard seamless steel pipe Oil Ministry, spiral seam steel pipe, straight seam steel pipe; polyethylene outer sheath tube made of high-density polyethylene resin with high mechanical strength and excellent corrosion resistance ; polyurethane insulation materials for the core density of not less than 60kg/m3 polyurethane foam, the foam completely fills the gap with polyethylene pipe between the outer protective tube and pipe work between the adhesive and the outer protective tube firmly to ensure work steel, polyethylene and polyurethane outer jacket pipe insulation three form a solid whole.

1 . Working steel ( zinc-rich primer paint wall ) 2 . Insulation materials ( glass wool ) 3 . Reflective layer of aluminum foil 4 . Stainless steel strap 5. Rigid insulation material 6. Sliding steel skeleton 7 . Jacket pipe ( wall processing coating )

" Outer steel prefabricated steel sleeve slide buried steam pipe insulation " is mainly used in the field of urban central heating , industrial heat pipes. Can be used to transport operating temperature no higher than 350 ℃, pressure is less than 1.6Mpa steam media. With insulation effect, small footprint , waterproof effect , long life and other characteristics .

Work pipe ( core tube ) outside brushing Promise zinc-rich primer coating , electrochemical corrosion protection methods for steel pipe work and prolong life .

Glass wool insulation materials , multilayer dressing, reduce heat losses ; reflective foil insulation layer is added , using the principle of reflection of radiation heat loss is further reduced to ensure that outer tube temperature below 50 ℃.

Flexible sliding steel skeleton form , which is to ensure the concentricity of pipe work between the pipe and the jacket can be guaranteed to work by the free sliding of steel . Between the sliding steel skeleton and work hard pipe insulation ring set , preventing the generation of thermal bridges .

Provided between the insulation and jacket pipe air layer can be used as a gas flow channel , with a row of nearby tidal tube mounting bracket , the pipeline runs through the exhaust pipe exhaust insulation influx of moisture.

Coat steel to form a closed system , effectively solve the waterproof anti- leak difficult.

Coat the outside of the pipe coating process , an effective solution jacket pipe buried corrosion problems.

" Rigid polyurethane spray prefabricated buried polyethylene pipe insulation wrapped " by the working pipe ( core tube ) , spray polyurethane insulation, extruded polyethylene outer protective layer. And an outer protective insulation layer thickness in the layer thickness can be produced within a certain range of any adjustments as needed. Production can be quantified according to the thickness of the insulation layer parameters and the actual heat loss of central heating and cooling required in the medium to meet the needs of different projects.

Product Features :

( A ) the density polyurethane insulation , thermal conductivity, strength and other indicators show a uniform core product overall good .

(B ) freedom of polyurethane insulation foam molding , the cell initiates axial direction perpendicular to the pipe , insulation compressive strength .

(C ) spray polyurethane insulation layer forming material in a liquid is sprayed onto the pipe surface , is then initiated , the high reactivity of spraying polyurethane raw materials , other than the adhesion process .

(Iv ) a polyurethane foam surface roughness, and a favorable bonding insulation between the outer protective layer .

( Five ) polyurethane insulation as needed thinnest coating thickness 15mm-20mm.

( Six ) polyethylene outer sheath to ensure its function under the premise of reduced thickness and cost savings.
