Product Description Product Description3LPE Steel Pipe Coating Production LineProduct Overview:The 3LPE (Three-Layer Polyethylene) Steel Pipe Coating Production Line by Qingdao Huashida Machinery Co., Ltd. is engineered for high-performance anti-corrosion coating of steel pipes. This line supports pipe diameters ranging from 159mm to 1400mm, with an extrusion capacity up to 350 kg/h, customizable to specific production requirements.This advanced production line is the result of years of dedicated development and innovation, fulfilling the increasing market demand for durable, efficient, and high-performance anti-corrosion solutions.3-Layer PE Coating System Composition:The 3LPE anti-corrosion coating system comprises:Fusion-Bonded Epoxy (FBE) Primer LayerThermosetting, non-toxic coating that cures into a high molecular weight, cross-linked structure.Provides excellent chemical corrosion resistance and superior adhesion.Polymer Adhesive Middle LayerTypically a polyolefin copolymer (e.g., vinyl copolymer) that chemically bonds with both the epoxy primer and polyethylene top layer.Polyethylene (PE) Top LayerEnsures high mechanical protection and environmental resistance, ideal for buried pipelines.This 3-layer coating structure ensures superior adhesion, excellent mechanical strength, and long-lasting anti-corrosion performance, making it widely used in oil & gas pipelines, urban gas distribution, and water transmission lines.Technical Process Flow:Pipe LoadingScrew Conveyor TransferSurface Cleaning & Induction HeatingEpoxy Powder CoatingAdhesive and Polyethylene Extrusion CoatingCooling Spray TreatmentPipe Unloading & GrindingKey Specifications:Pipe Diameter Range: 159mm - 1400mmExtrusion Output: ≤350 kg/hApplication: Steel pipe external anti-corrosion coating for buried pipeline systemsProduct Parameters Configuration listNo.NameUnitQtyRemarksExternal cleaning and 3PE system of the steel pipes1Flatform of Upload pipesM15Combination of dual structure2Hydraulic tube pulling machineset 8Double lift,lifting force more than 8T3Air hydraulic stationSet3Air cooler, throttle valve4Derusting spiral transmission lineM27Variable frequency speed regulation, solid tyre5Synchronous dynamic spiral single-frameSet2Variable frequency speed regulation, solid tyre6The lower type shot blasting machineSet1Max pipe diameter 1220mm7Dedusting systemSet1first degree dust removal + pulse bag type dust collector8transition platform line M15Combination of dual structure9PE Spiral transmission lineM54Variable frequency speed regulation,solid tyre10Intermediate frequency heaterSet1800K 11Dynamic high temperature rollerSet1Variable frequency speed regulation12Epoxy powder coating systemSet1Max pipe diameter 1220mm 13The powder room, vulcanization barrelSet1Non inductive heating material14two stage powder recovery deviceSet1cyclones dust collector+pulsed dust collector15Automatic vacuum feeding machine Set2800kg/h+300kg/h 16SJ-180/30ExtruderSJ-180/30ExtruderSet1Q≈650kg/h250KW DC,Q≈650kg/h 17SJ-65/30 ExtruderSJ-65/30 ExtruderSet145KW Q≈150kg/h45KW AC,Q≈150kg/h18Extruder moving mechanismSet1Electric control19Hot melt extrusion die headSet1T die head20PE sheet extrusion die mouldSet1T die head21Hot melt adhesive PE coating deviceSet1Silicon rubber roller, double cylinder, internal water cooling22Environmental protection ventilation systemSet14KW 23cooling spray systemSet1Water pump, water spray, pipelines, reflux tank24The cooling splash-prevented plastic curtain-wallSet1Approx 110m225External anti-corrosion pipe unload platformM15Combination of dual structure26Pipe beveling grinding machineSet24KW motor electrical control system of walking27Dedusting systemSet2Pulse dust collect28Hydraulic lifting rotary pipe deviceSet1Hydraulic lift,the four round of the WPA direct drive29The electrical control system of 3PE steel pipes production lineSet1main line of centralized control/individual/controlPLC Control compressed air system30Screw type air compressorSet16m3/min,0.7MPa 31freeze drying machineSet16m3/min,Enter temperature≤80oC32Precision filterSet30.1PPM 33Gas tankPC11m3 Company ProfileQingdao Huashida Machinery Co., Ltd was established in 2003 and has focused on plastic pipe extruder production line and joints of plastic pipes and 2PE 3PE pipes machinery for over 16 years, we are a private high-tech enterprises integrated by R&D, manufacturing, selling, service and trading.We are always concertrating on research and development of plastic extrusion equipments, tightly cooperating with Tsinghua University, Beijing University of chemical technology, South China university of technology and some other colleges and scientific research institutions.
