Product details

The heat preservation spiral steel pipe is the heat preservation treatment to the spiral steel pipe. The main insulation method is the polyurethane heat preservation spiral pipe, first carries on the rusting to the steel pipe and so on the pre processing, then sets up a polyethylene coat, the thickness decides according to the customer's needs, fills the foam between the tube and the polyethylene skin, the thickness of the foam is also processed according to the customer's need. The installation of heat preservation spiral steel pipe can be either overhead or buried.

Spiral heat preservation pipe is the abbreviation of heat insulation pipe, which is used for the transportation of liquid, gas and other media. It is also used in the heat insulation engineering of oil, chemical, aerospace, military, central heating, central air conditioning, municipal and other pipelines.

When the spiral heat preservation pipe is buried deep underground, it must be treated on the surface, so that it will not be corroded by some corrosive bacteria in the soil when it is buried deep underground. Generally, our pipeline laying types include gas or liquid transmission, drainage pipes of some factories, etc. for these pipes, there is no obvious design in the traditional method to ensure that the transmission efficiency of the insulation pipe will not be lost due to the change of the external environment. The spiral heat preservation pipe has the excellent characteristics of light capacity, high strength, heat insulation, sound insulation, fire resistance, cold resistance, corrosion protection, non water absorption, simple and quick construction, and has become an indispensable material for heat insulation, water-proof and leakage stoppage, sealing and other industrial sectors such as construction, transportation, petroleum, chemical industry, electric power, refrigeration, etc. Spiral insulation pipe insulation layer material is density 60m^3 polyurethane foam. The gap between the steel pipe and the casing pipe shall be fully filled, with certain bonding strength, so that the steel pipe, the outer sleeve and the insulation layer form a solid whole.
