Black jacket straight seam steel pipe has outstanding mechanical and adiabatic functions

Polyurethane direct-buried insulating steel pipe is an ideal product for central heating because of its good quality and low price. The rapid starting speed of polyurethane insulating pipe usually occurs in spring and summer or in noon construction. Because of the sudden rise in temperature, the temperature is too high. The black material can be cooled by cold water or naturally placed outdoors at night to prevent direct sunshine. Salesmen and customers who have inquiries can call for consultation or come to the factory for investigation.

Polyurethane foam insulation pipe, polyurethane directly buried insulation pipe, also known as "tube in tube", has a "two step method" consisting of high density polyethylene external protective layer, polyurethane rigid foam plastic pipe and steel pipe.

1. Anti-corrosive coating: Protect external steel pipe from corrosive substances, prolong the service life of steel pipe.

2. External steel pipe protection: to protect the insulation layer from groundwater corrosion, to support the operation pipe and to accept certain external loads, to ensure the normal operation of the operation pipe.

3. polyurethane foam layer: ensure the temperature of the medium and ensure the surface of the outer tube is kept at normal temperature.

4. barrier, reflective layer: ensure that the organic foam data do not enter the inorganic rigid high temperature resistant layer; reflect the heat resistant part of the heat.

5. inorganic hard insulation: high temperature, ensure the interface temperature between the organic insulation layer and ensure that the foam is not carbonized.

6. Drag Reduction Layer: Ensure that the hot expansion, cold contraction and free movement of the working steel pipe.

7. Operating steel pipe: Ensure the normal activities of transport media.

The insulation layer material is rigid polyurethane foam with density 60kg/m3 to 80kg/m3, which fully filled the gap between the steel pipe and the casing, and has a certain bonding strength, so that a solid whole can be formed between the three parts of the steel pipe, the outer sleeve pipe and the insulation layer. Polyurethane foam insulation steel tube foam has outstanding mechanical function and adiabatic function. Under normal circumstances, it can withstand 120 degrees of temperature and is able to withstand temperature of 180 degrees when modified or combined with other heat insulation materials.
