Buried polyurethane prefabricated insulating tube

Buried polyurethane prefabricated insulating tube is composed of a steel pipe, plastic polyurethane rigid foam insulation layer and glass avant-garde enhancement (i.e. glass steel) prefabricated outer protective layer combined closely tube.

Polyurethane insulation pipe has the capacity of light, high strength, heat and sound insulation, flame retardant, cold resistance, anti-corrosion, non absorbent, convenient construction and other excellent characteristics, has become the construction, transportation, petroleum, chemical, electric power, cold storage and other industrial sectors insulation, waterproofing, sealing and other essential materials. Polyurethane insulation pipe used for various indoor and outdoor pipe, heating, cooling, oil, gas and other pipeline, central air conditioning, chemical, pharmaceutical and other industrial pipe insulation, cold preservation engineering.

Compared with the traditional types of pipe insulation pipe buried prefabricated polyurethane insulation has the advantages of very prominent:
1, good performance of heat preservation, heat loss is only the traditional pipe 25%, long-term and can save a lot of energy operation, significantly reduce energy costs.
2, has the very strong waterproof and corrosion resistance, without a trench, can be directly buried in the ground or water, construction is simple and rapid, low comprehensive cost.
3, under the condition of low temperature also has good corrosion resistance and impact resistance, can be directly embedded underground permafrost.
4, the service life can reach 30-50 years, the correct installation and use of the pipeline repair cost is very low.
5, you can set the alarm system, automatic detection of pipe network leakage fault, accurate fault location and automatic alarm indication.

Anti-corrosion steel pipe

Anti-corrosion steel pipe is processed through the preservation process, which can effectively prevent or slow down the process in the transport and use of chemical or electrochemical corrosion reaction of steel pipe.

Sunny Steel Internal and External Anti-corrosion steel pipe services: Anti-corrosion steel pipe in the country is mainly used for petroleum, chemical, gas, heat, sewage treatment, water, bridges, steel pipes and other engineering fields.anti-corrosion steel pipe is divided into the following categories:

IPN8710 Water pipe inner wall
When the corrosion of steel in more types of media, such as acids, alkalis, salts, oxidants and water vapor, etc., the coating must be chemically inert, acid salt corrosion, the coating should be compact structure, water permeability, adhesion, tough fullness. Such cases for IPN8710 corrosion.
IPN8710 anti-corrosion primer: from polyurethane, polyethylene, modified epoxy resin, non-toxic anti-corrosion pigments, additives and other components, room temperature curing to form interpenetrating networks, dense coating structure, acid, alkali, salt, rust performance, strong adhesion for water supply pipeline wall corrosion primer paint. IPN8710 anti-corrosion finish: from the epoxy, rubber, resin-modified, non-toxic anti-corrosion pigments, additives and other components. Excellent chemical resistance, non-toxic, anti-microbial corrosion, corrosion protection for water supply pipeline wall finish.

FBE epoxy powder corrosion
FBE epoxy powder anti-corrosion structure: electrostatic spraying the surface of the steel epoxy powder coating, a film. The coating has a coating operation is simple, clean, coating impact resistance and bending properties, temperature resistance advantages.

3PE / 2PE steel pipe 
2PE/3PE corrosion structure: the surface of the steel and epoxy powder electrostatic spraying adhesive side wound, lateral wound polyethylene coating, combined with the excellent performance of the three, thus significantly improving the overall quality of pipeline corrosion. Resistant to chemical corrosion, resistance to cathodic disbondment resistance, mechanical damage to properties.

Coal tar epoxy anticorrosive
Coal tar epoxy anticorrosive structure: from the epoxy resin + filler made of coal tar pitch + anti-corrosion coatings on steel surface coated with glass cloth to strengthen the formation of a coating, commonly used in the pipe wall corrosion. Thickness of 0.5 ~ 1.0mm.

High-density polyethylene jacket corrosion
High density polyethylene jacket corrosion structure: the outer surface of pipe wrapped in high-density polyethylene material, with a high mechanical strength and excellent corrosion resistance, can protect the steel in the transportation, installation and use of the process to avoid external factors the damage. Manufacture of stent should be added antioxidants, UV stabilizers and carbon black, etc. Polyethylene jacket tube easy to aging, such as open storage tarpaulin and other items appropriate to cover, dumps should stay away from high heat and fire, anti-corrosion steel pipe made after the ban exposure, sudden cold, or polyethylene jacket tube easy to crack, the impact product performance and service life.
