Introduction to TEPE anti-corrosion steel pipe

Description :

　　TPEP anti-corrosion steel pipe production plant for drinking water and TPEP anti-corrosion steel pipe for water conservancy engineering. Hebei News Information (Reporter Gao Editor) recently learned that Cangzhou Youtong Pipe Industry Co., Ltd. is an upgraded product based on external polyethylene and internal fusion bonded epoxy composite steel pipe, which is currently an advanced anti-corrosion form for buried long-distance pipelines. It is a new type of anti-corrosion production line for large-diameter pipelines independently developed by Youtong Pipe Industry Co., Ltd. based on advanced anti-corrosion technology from abroad and the company's 30 years of anti-corrosion experience. The outer wall adopts a three-layer structure anti-corrosion layer formed by hot melt bonding and winding technology, with the bottom layer of epoxy resin, the middle layer of adhesive, and the outer layer of polyethylene. The inner wall adopts a thermal spray epoxy powder anti-corrosion method, and the powder is uniformly coated on the surface of the pipe body after high-temperature heating and fusion. Greatly improved coating adhesion and thickness, enhanced resistance to bumps and corrosion.

　　TPEP anti-corrosion steel pipe: The Chinese name is, externally wrapped polyethylene and internally fused epoxy anti-corrosion steel pipe, which is a TPEP anti-corrosion steel pipe technology for long-distance water transmission pipelines. As its full Chinese name indicates, the outer wall of the pipeline adopts a 3-layer PE structure anti-corrosion technology wrapped with polyethylene, and the inner wall adopts hot-melt epoxy anti-corrosion treatment. Cangzhou Youtong Pipe Industry Co., Ltd. is one of the leading manufacturers of TPEP anti-corrosion steel pipes in Cangzhou area. This inspection is led by department level officials from the Ministry of Industry and Information Technology, the Ministry of Natural Resources, the National Development and Reform Commission, the Ministry of Emergency Response, the Tax Headquarters, the State Administration for Market Regulation, and other departments. Industry associations, experts, and mainstream news media participate in the inspection, which is divided into 8 inspection teams for a period of one month. The focus is on inspecting the implementation of local rectification work deployment, the implementation of 3pe anti-corrosion pipe enterprise policies, and the investigation and punishment. For enterprises with prominent problems such as unplanned and unplanned production, unlicensed exploration and mining, buying and selling 3pe anti-corrosion pipe products, environmental pollution, and tax evasion, as well as places where work is not implemented, supervision is not in place, and investigation is not timely, they will be reported nationwide and relevant personnel will be held accountable in accordance with the law. Overview of polyurethane insulation pipe: Prefabricated polyurethane direct buried insulation pipe mainly consists of four parts. Provide anti-corrosion protection and decorative effect on the surface of the material. The epoxy resin series anti-corrosion coatings have excellent properties such as high toughness, abrasion resistance, aging resistance, acid alkali salt corrosion resistance, strong adhesion, resistance to hydrolysis, gasoline, kerosene and other media, and non combustible and non combustible properties.

　　The upper and lower limits of the adhesive layer thickness for TPEP anti-corrosion steel pipes for non-toxic drinking water production plant (1) are 170-250 μ m according to the provisions of Table 2.0.2 in SY/T0413 standard. The solid foundation of pellet ore is laid, and the sintering workshop controls the sintering air volume, vacuum degree, material layer thickness and other indicators to produce sintered ore with good permeability and high grade. It can be used as fuel for ironmaking blast furnaces in one go. The deviation range of 3pe anti-corrosion steel pipe wall thickness fundamentally refers to the thickness deviation range of the anti-corrosion layer and the wall thickness deviation range of the pipe material. Corrosion of pipelines will occur successively, causing unpredictable losses to personnel and property. There are three main forms of organic coating peeling: permeable bubbling, cathodic peeling, and anodic damage. The anti-corrosion coating of 3PE anti-corrosion steel pipes is crucial for the service life of buried pipelines. For pipelines of the same material, some can be buried underground for decades without corrosion. It can be directly purchased underground or in water, and the construction is also simple and fast, with a relatively low overall cost. The water supply pipeline uses 3PE anti-corrosion steel pipe with a three-layer structure of polyethylene anti-corrosion coating (3PE), which combines the excellent properties of fusion bonded epoxy powder coating and extruded polyethylene anti-corrosion coating. Therefore, it has a wide range of applications, not only for anti-corrosion of steel, but also for non-metallic components such as concrete and wood. In recent years, it has been widely used in industrial sectors such as water engineering, power plants, chemical engineering, and fertilizers for equipment, as well as in underground and above ground engineering anti-corrosion of oil, gas, and water pipeline systems and civil structures. Epoxy resin and epoxy resin adhesive themselves do not have #, but due to the addition of solvents and other substances during the preparation process, many epoxy resins have #. The domestic epoxy resin industry is using water-based modification and avoiding additives to maintain the "# free" nature of epoxy resin. Epoxy resin is generally used together with additives to obtain application value. Additives can be selected according to different purposes.
