spiral steel pipe suppliers At present, three layers of PE composite structure, epoxy resin powder (FBE), coal tar porcelain, epoxy coal tar pitch and PE tape are commonly used as outer anti-corrosion coatings for buried gas pipelines.Three-layer PE composite structure and epoxy resin powder anti-corrosion coating have excellent performance, so they are also the main anti-corrosion coating for buried pipelines in Europe and America [1].In China, from the durability, maintenance costs and other comprehensive economic factors, generally preferred three layers of PE composite structure anticorrosive coating.

Different anticorrosive methods have different anticorrosive quality and cost, so the anticorrosive method and cost should be considered comprehensively according to the different pressure, use, environment and gas transportation of the spiral steel tube.In the consideration of economic rationality should pay attention to two points: (1) gas pipe network construction of a corrosion protection investment, (2) gas pipe network after the operation of maintenance costs.As the urban gas pipe network is located in the urban area, it is difficult to maintain and repair after operation and the cost is high. Therefore, an investment should be appropriately increased to reduce the daily maintenance workload of the pipeline after operation.


Epoxy coal asphalt anticorrosive spiral steel pipe is what we often say several cloth several oil, common have one cloth two oil, two cloth three oil, three cloth five oil, four cloth seven oil.Epoxy coal bitumen anticorrosive spiral steel pipe consists of epoxy coal bitumen primer and topcoat, which are made of epoxy resin and coal bitumen as main film forming materials, adding various anti-rust pigments, insulating fillers, toughening agents, levelling agents, diluents and anti-sinking agents.Appearance: iron red primer group a, black primer group b, black finish.Excellent chemical medium corrosion resistance and good physical and mechanical properties, good adhesion, coating tough, and has excellent electrical insulation and permeability, anti-stray current and anti-microbial erosion, after the film, can reduce the number of construction tracks.The main standards are SY/T 047-96 technical standard for epoxy coal asphalt anticorrosive coating for buried steel pipelines and SY/T 0457-2000 technical standard for anticorrosive coating for liquid epoxy coating for steel pipelines.It is mainly used for anticorrosion of the outer wall of buried or underwater steel oil, gas, water supply and heating pipelines, and also for the anticorrosion of all kinds of steel structures, wharfs, ships, sluice gates, gas storage tanks, oil refining and chemical plants, concrete pipes, sewage ponds, roof waterproof layer, toilets, basements and other concrete structures.
