Insulation steel pipes are widely used in liquid and gas transmission pipe networks, chemical pipe insulation projects in petroleum, chemical, central heating and heating networks, central air-conditioning ventilation pipes, and municipal engineering. High-temperature prefabricated direct-buried thermal Insulation steel pipe is a direct-buried prefabricated thermal Insulation steel pipe with good thermal insulation performance, safety and reliability, and low construction cost.

Specification

1. The pre-insulated steel pipe coated with high density polyurethane foam can resistant the temperature up to 140°c 
2. With the corrosion resistant HDPE jacket pipe can make the pipe directly buried underground without trench.
3. Different size pipe and pipe fittings can service for different heating and cooling project.
4. The polyurethane foam thickness can be designed from 26.5-83mm or more.

Applications-Pre-insulated pipe system are used by the chemical, pharmaceutical, petro-chemical and food industries for the transport of:

1. District heating networks
2. District cooling networks
3. Chilled water, Drinking water, Waste water, Cooling water, Hot water
4. Steam & condensate lines
5. Process fluids
6. Refrigerants
7. Chemicals
8. Oil

A pre-insulated pipe normally consists of three parts

Part 1:  Carrier pipe (Inside): Stainless steel or Carbon steel
Part 2:  Insulating layer (Medium): Polyurethane foam (PUR Form) (High insulation qualities compared to mass and volume)
Part 3:  Protective jacket (Outside casing): Plastic or steel (Polyethylene (PEH), High Density Polyethylene (HDPE), Galvanized, Aluminum etc)

Pos: The choice of carrier pipe, foam type and foam thickness, as well as the material for the jacket, is made by the customer, who can also choose to supply carrier pipes for the project.

Advantages: impact-proof, watertight, resistant to salt and chemicals, hygienic and non-corrosive
