Product Description Product Description 1.Inner epoxy resin outer polyethylene coated composite steel pipe is a steel-plastic composite product with anti-corrosion properties made from pre-treated steel pipe as the base pipe, fusion bonded epoxy powder coated on the inner surface of the pipe after heating and polyethylene powder coated on the outer surface of the pipe.2. The most perfect product in water conservancy pipeline industry. The pipe body and socket anti-corrosion layer performance to be consistent. Flexible socket and the perfect combination of anti-corrosion, both the industry's best anti-corrosion way, but also the industry's most convenient way of connectingNominal 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≤4000>0.45>1.5>1.8Note: can be customized as customer's needs.Product Features1.Corrosion resistanceAnti-corrosion materials polyethylene and epoxy resin are polymer materials with excellent corrosion resistance, effectively preventing soil and fluid damage to the pipeline to increase the service life of the pipeline.2. Excellent hydraulic propertiesSmooth inner wall, not easy to scale, low coefficient of friction, smooth surface and non-adhesive properties to ensure the pipeline conveying capacity, but also reduces the pressure loss of the pipeline and water transmission energy consumption.3. Good hygiene performanceThe surface of epoxy resin coating inside the pipeline is smooth, not easy to scale, safe and hygienic, and the anticorrosion material meets the requirements of GB/T17219 health standard, which effectively avoids the contamination of the pipeline to the water quality.4. Superior adhesion of coatingEpoxy resin, polyethylene powder raw materials after modification, and metal to form a strong chemical bond, strong adhesion. The outer polyethylene layer has good toughness and impact resistance, able to resist scratching caused by dragging and knocking, and resistant to plant root puncture.5. Long lifeAnti-corrosion steel pipe can be used continuously for 30~50 years under the condition of normal construction and use, which is a significant increase in the life span of ordinary steel pipe.6. Good connection securityA variety of connection methods to meet different environments, different pressure requirements. Pipes are generally flanged, quick coupling, butt welding, lined with stainless steel, socket connection, etc. The connection is mature and reliable. Appliation CasesOur Advantages 1.The final quality level of the product depends on the process design and manufacturing process, Donghong with sophisticated equipment for product quality key process control and incorporate years of manufacturing experience, to provide customers with high quality products, to become a trustworthy enterprise.In response to the growing demand for large-diameter pipelines, Donghong has added large-diameter anticorrosion steel pipe to provide first-class products against international standards. 2.In order to meet the needs of different projects, Donghong has developed various connection methods for large diameter anticorrosive steel pipe, such as flexible socket connection, butt welding, socket lap weld, ball lap weld, customized bevel form and other connection forms, which provide a variety of choices for the project. In the industry was the first to develop a large-diameter socket flexible connection, the maximum socket caliber can reach 1.8M, and the first to be used in key water conservancy projects in China, becoming China's large-diameter steel pipe socket connection pioneers and leaders.Donghong has a large-diameter, high-pressure pipe fittings factory, which produces large-diameter, high-pressure pipe fittings for projects, and can also help customers customize special pipe fittings according to customer requirements and project environment.Other connection methods.Socket type connectionFlange ConnectionClamp Connection Company ProfileAbout usDonghong(Shandong Donghong Pipe Industry Co., Ltd.)
