ASTM A106/53 Gr. a /Gr. B / Gr. C Polyurethane Insulated Steel Pipe Hebei Canghai

With years of excellent experiences on LSAW Pipe and Pipe fittings, Hebei Canghai Nuclear Equipment Technology Co.Ltd. has became the reliable supplier and partner to our clients in pass decades.PE insulation pipe is also known as PE outer protection pipe,jacket pipe, sleeve pipe. The outer protective layer of the directly buried polyurethane insulation pipe is HDPE insulation pipe, and the middle is filled with polyurethane rigid foam as the insulation material layer, and the inner layer is steel pipe. Polyurethane directly buried thermal insulation pipe has good mechanical properties and thermal insulation properties with good impact resistance. Under normal circumstances can withstand the high temperature of 120-180°C, suitable for all kinds of cold and hot water high and low temperature pipeline insulation engineering. It is usually used in indoor and outdoor pipelines, central heating pipes, central air conditioning pipes, chemical and pharmaceutical industrial pipelines of insulation, cold engineering, oil pipeline engineering, etc. Insulation pipe production line adopts special PE insulation pipe mold design, extrusion pressure is stable, thin wall pipe thickness uniform. The extrusion speed is fast, the blow molding output is greatly improved, the surface is brighter, and the operation is highly automatic.

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:

District heating networks
District cooling networks
Chilled water, Drinking water, Waste water, Cooling water, Hot water
Steam & condensate lines
Process fluids
Refrigerants
Chemicals
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
