Product introduction
The technology is the insulation layer and anti-corrosion layer and coated on the surface of the steel tube tract, to form the pipeline anticorrosion and thermal insulation layer is a domestic initiative. Compared with other methods, with continuous operation, high production efficiency, low cost, energy saving, no environmental pollution etc. advantages, 1985 won the second prize of national scientific and technological progress, science and technology to update several times to the international advanced level.
New "one step" process characteristics:
1, a wide range of materials can be made of epoxy powder and various coatings on steel pipe anti-corrosion.
2, foam can be used in high temperature foam and polyester foam asphalt.
3, jacket layer and foam layer bonding, foam layer and anti-corrosion layer bonding, corrosion protection layer and steel pipe bonding firm.
With one - step molding method, the automation degree of the steel pipe line insulation anticorrosion production line is high, and the quality of the insulation layer is completely in line with the national standard.
The technology since 1983 has been successfully developed, improve the improvement of nearly 20 years, has formed pipeline operation range of phi 48mm ~ Phi 1000mm above. Adiabatic anticorrosion layer steel pipe is mainly used for transportation of crude oil pipeline, directly buried heating pipeline and refrigeration system piping insulation and corrosion resistant and application prospect is very extensive, the investment return rate is extremely high. Can be applied to the central heating units, long-distance oil transportation, water supply, gas supply and other projects.
Steel pipe anticorrosion insulation foam jacket forming technology is the early eighties, by original petroleum Infrastructure Department Bureau organized experts visited Canada after, new technologies in the promotion of the domestic oil field and based on two-step forming process in foreign countries, by Shengli oil field Youjian technology research the in 1983 launched the first "one-step" molding technology, pipeline steel foam anti-corrosion insulation molding technology and external insulation jacket layer forming a, which we call the "one-step" operation. The success of this technology, not only to improve the work efficiency, also saves the material, reduces the cost, convenient construction, soon this technology has obtained the promotion in the oilfield, and access to the Shandong Province top ten scientific and technological achievements, 1985 obtained the national invention patent, straight to the present, there is no domestic "one-step" technology came into being.
