Description :

　　Cangzhou Guanghui Pipeline Co., Ltd. was founded in 2008 and is a large-scale steel pipe enterprise that produces double-sided submerged arc spiral welded steel pipes, straight seam welded pipes, and anti-corrosion and insulation steel pipes. Longdu Company is located in the Puwa Industrial Development Zone in the south of Yanshan City, Hebei Province, China's steel pipe production base, ten kilometers south of Yanshan County, covering an area of 150 acres. Located to the east of Huanghua Port and to the north of Beijing and Tianjin, the 205 National Highway, 104 National Highway, and Beijing Shanghai Railway intersect and pass through, making domestic transportation very convenient; In addition, it is only 200 kilometers away from Tianjin Xingang, providing more convenient conditions for export business and developed communication. The company has a working capital of 100 million yuan and currently has 330 employees, including over 15 senior engineers with decades of management experience. With over 31 technicians, we currently have four advanced spiral steel pipe production lines in China, producing 200000 tons of double-sided submerged arc spiral welded steel pipes with a diameter of 219-3620mm and a wall thickness of 5-22mm annually. Our products comply with SY/T5037-2000 and GB/T9711.1-1997 standards, and we have two production lines for straight seam welded pipes and seamless steel pipes with a diameter of 89mm-1620mm and an annual production capacity of 100000 tons; The product is mainly used for long-distance transportation pipelines of fluids such as oil, natural gas, coal gas, water, steam, as well as supporting projects such as heating, dredging, chemical engineering, refrigeration, wellbore casing, and pile driving.

　　Cangzhou Guanghui Anti corrosion and Insulation Steel Pipe Co., Ltd., invested and built by the company in 2010, is one of the large enterprises in North China that processes and produces 3PE anti-corrosion steel pipes, steel pipe anti-corrosion processing, and various anti-corrosion steel pipes for oil and natural gas. The company now has an internationally advanced 3PE (three-layer polyethylene coating) anti-corrosion production line and polyurethane insulation pipeline production line, producing 3PE/2PE anti-corrosion steel pipes and polyurethane insulation steel pipes with specifications of 219mm-1620mm, which are used for oil pipelines, natural gas pipelines, coal mine gas pipelines, heating pipelines, and water supply pipelines. Execution standards: DIN30670/DIN30671, SY/T0413-2002, SY/T0315-97, GB/T23257-2009, can undertake steel pipe outer wall epoxy coal tar (one cloth two oil, two cloth three oil, three cloth five oil, etc.) steel pipe anti-corrosion, steel pipe inner wall IPN8710 drinking water paint, plastic coated composite steel pipe, cable conduit, fire water supply plastic coated composite steel pipe, groove connection plastic coated steel pipe, etc

　　Epoxy resin composite steel pipe is a steel plastic composite product that uses steel pipe as the base pipe and plastic powder as the coating material. A plastic layer is melted and coated on the inner surface, and a plastic layer or other material anti-corrosion layer is melted and coated on the outer surface. Plastic coated steel pipes are divided into polyethylene coated steel pipes and epoxy resin coated steel pipes according to the different internal coating materials. The product marking consists of the code for the coated composite steel pipe, the code for the inner coating material, and the nominal size. Water supply lined plastic composite steel pipe is made by lining the inner wall of the steel pipe with thermoplastic pipes such as polyethylene (PE), heat-resistant polyethylene (PE-RT), cross-linked polyethylene (PE-X), polypropylene (PP-R), rigid polyvinyl chloride (PVC-U), chlorinated polyvinyl chloride (PVC-C), etc. according to the requirements of the conveying medium. Due to technological improvements, some products have added an outer plastic layer. The product is divided into plastic lined steel pipes for cold water and plastic lined steel pipes for hot water according to the temperature of the transported water. The product label consists of the code for the lined plastic steel pipe, the code for the lined plastic material, and the nominal diameter. Consumers should try to choose reputable products from large shopping malls and stores according to their actual needs when purchasing such products.

　　There are three main explanations for the formation mechanism of scaling caused by water corrosion on the inner wall of metal pipelines. One theory is called oxidation theory, which states that due to carbonation in water, iron becomes ferrous carbonate, which is then oxidized by oxygen in the water to form iron hydroxide; The second theory is called peroxidation theory, which means that iron first combines with water to form ferrous hydroxide, and the hydrogen produced reacts with water to form hydrogen peroxide. Then, ferrous hydroxide and hydrogen peroxide react to form iron hydroxide. The coated steel pipe material is excellent and has good performance, which not only reflects the properties of the original metal material, but also increases corrosion resistance and the aesthetics of the iron tower, protecting the environment and saving resources. Poor quality and unqualified coated steel pipes pollute the water environment, causing corrosion and scaling inside the pipes, which affects water quality. When using, it is important to avoid choosing coated pipes because they are cheap. High quality coated pipes should be selected to ensure the safety, environmental protection, and hygiene of drinking water. The manufacturer of plastic coated composite steel pipes for water supply and drainage uses epoxy resin coated composite steel pipes for fire protection, which are based on steel pipes.

　　A new type of composite material made by melting spraying or adsorbing food grade epoxy powder coating or PE raw materials on the inner wall through special processes and curing at high temperatures. This composite steel pipe is a product that uses PE (modified polyethylene) for hot-dip molding or EP (epoxy resin) for internal and external coating, and has excellent corrosion resistance. At the same time, the coating itself also has good electrical insulation and will not produce electrical corrosion. Low water absorption rate, high mechanical strength, low friction coefficient, capable of achieving long-term use. It can also effectively prevent damage to plant roots and soil environmental stress. Inner oxygen outer polyethylene anti-corrosion steel pipe is a new type of steel plastic composite pipe, which is composed of steel pipe substrate, epoxy resin inner coating and polyethylene outer coating, and has excellent mechanical properties and corrosion and aging resistance. Widely used in many industries such as water conservancy, power, chemical, petroleum, etc.
