Product Description Hot Selling PipesSteel Wire Reinforced PE Composite PipeFiberglass Steel Wire Reinforced Composite PipeHDPE PipePVC PipeAntistaic Flame Redartant Composite Pipe for MiningAnti-corrosion Composite PipeThermal Insulated PipeBig Carliber Composite Steel PipeProduct DescriptionThe 3pe anti-corrosion layer(three-layer extruded polyethylene anti-corrosion layer,TPEP)on the outer surface of the steel pipe is made of fused epoxy powder(FBE) as the bottom layer,adhesive as the middle layer,and extrued polyethylene as the outer crover.It is an emerging product that solves the promble of the corrosion prevention of the inner wall of 3PE anti-corrosion steel pipes.It fills the gap of anti-corrosion of domestioc anti-corrosion steel pipes in the field of water transportion.The inner and outer epoxy resin 3PE anti-corrosion steel pipes are currently the best choice in the field of water supply pipes.The Advantage:1.Light WeightCompared with the same specification of the steel pipe, the weight of the steel pipe saves 50% -150%,the pipe weight is light, reduce the construction labor intensity2.Corrosion preventiveFused epoxy powder coating, hot dip zinc and stainless steel, diversified selection can ensure the service life of the pipe.3.Negative pressure resistanceTo meet the negative pressure performance requirements of the pipe for gas drainage, under-0.097MPa pressure, 100h pipe without suction, deformation.4.Low operating noiseThe inner wall of the pipe is a flat wall structure, with the inner wall smooth and low noise during normal operation.5.Strong adhesionThe selection of anti-corrosion materials are the national standard mature technology type, the use of the process does not fall off, peeling phenomenon.Application CasesProduct ParametersNominal Diameter/ mmInner Coating Layer /mmOuter coating layer,mmOrdinary levelStrengthen levelDN ≤65>0.3>0.6>0.865≤DN≤150>0.35>0.8>1.0150≤DN≤300>0.35>0.8>1.2300≤DN≤800>0.4>1.0>1.3800≤DN≤1200>0.45>1.2>1.81200≤DN≤3600>0.45>1.5>1.8Note: can be customized as customer's needs.Production ProcessThe three-layer polyethylene anti-corrosion steel pipe combines the advantages of fused epoxy powder and polyolefin coating, overcomes the lack of performance of the two coatings when used alone, and is coated to the surface of the steel pipe by spraying, winding and other processes to achieve the purpose of anti-corrosion. Connection MethodIn order to adapt to the needs of different project characteristics, Donghong develops a variety of connection methods for large diameter anticorrosion steel pipe, specifically flexible socket connection, butt welding, socket lap weld, spherical lap weld, customized bevel form and other forms of connection, providing a variety of choices for the major water conservancy projects, to support a variety of construction environments and construction conditions. Donghong has set up a high-pressure pipe fittings factory, which produces pipe fittings of large caliber and high pressure for national key projects, and also helps customers customize special pipe fittings according to customer requirements and industrial and mining conditions, realizing the manufacturing concept of "good connection makes good system".Welding ConnectionMechanical Connection Socket Connection Company ProfileAbout UsShandong Donghong Pipe Industry Co., Ltd.
