Direct sales of large-diameter anti-corrosion spiral steel pipe, reinforced 3PE anti-corrosion steel pipe, cement mortar anti-corrosion steel pipe

Description :

　　The 3pe reinforced anti-corrosion steel pipe structure has three layers: one layer of epoxy powder, the second layer of adhesive, and the third layer of polyethylene. The three materials are integrated and firmly bonded with the steel pipe to form an excellent anti-corrosion layer. Advantages: 1. 3pe anti-corrosion steel pipes have extremely high sealing performance, and long-term operation can greatly save energy, reduce costs, and protect the environment. 2. Strong corrosion resistance, quick construction, and a service life of up to 30-50 years. 3. PE also has good corrosion resistance and impact resistance under low temperature conditions, with low water absorption rate. 4. Simultaneously possessing high epoxy strength, low water absorption of PE, and good flexibility of hot melt adhesive, it has high anti-corrosion reliability. The characteristics of this anti-corrosion are simple production process, good anti-corrosion effect, and low price. It is a widely recognized anti-corrosion method in the pipeline manufacturing industry. 2. Three layer polyethylene (3PE) steel pipe anti-corrosion for oil and gas, two-layer polyethylene (2PE) steel pipe anti-corrosion, standard: SY/T0413-2002; DIN30670。 Our company has a flexible business model, with both wholesale and retail operations and a minimum of one unit for sale. We are available 24 hours a day to serve you. We welcome new and old customers to inquire.

　　Epoxy resin anti-corrosion steel pipes for water transportation can effectively prevent damage to plant roots and soil environmental stress caused by long-term underground burial. After surface antifreeze treatment, it can be used in an environment of -30 ℃. The service life is more than 1-2 times that of other similar products. Steel plastic composite pipe (epoxy resin coated pipe, polyethylene coated pipe, etc.) - With the release of a notice, the use of galvanized steel pipes as water supply pipes is prohibited, and new types of plastic pipes are promoted. There are many types of plastic water supply pipes on the market, and through years of engineering applications, plastic pipes have more or less exposed some problems and shortcomings. Due to the high linear expansion coefficient of plastic pipes, some soft plastic pipes are not suitable for indoor exposed installation, as they undergo thermal expansion, contraction, bending, and deformation, which affects their appearance; Its temperature and pressure resistance gradually decreases with the increase of the temperature of the transmitted medium and the increase of its service life;

　　Plastic water supply pipes should not be exposed outdoors as they are easily exposed to sunlight and ultraviolet radiation. Accelerated aging; Some large-diameter plastic pipes are not suitable or economical due to consumables and difficult to control connection quality. The application of steel plastic composite pipes in the field of water supply has outstanding advantages. Steel plastic composite pipes (epoxy resin coated pipes, polyethylene coated pipes, etc.) have become relatively mature in developed countries and have been widely used in many fields such as petroleum, chemical, construction, shipbuilding, communication, power, and underground gas pipelines. For example, 80% to 90% of water pipelines in countries such as the United States and Japan use steel plastic composite pipes, which are currently the best products to replace traditional galvanized pipes. Epoxy resin anti-corrosion steel pipes produced by epoxy resin anti-corrosion steel pipe manufacturers are known as green and environmentally friendly pipes.

　　There are still some serious drawbacks to using epoxy coal tar coating for pipeline protection. According to experts from the China Epoxy Resin Industry Association, epoxy coal tar anti-corrosion steel pipes form a "glass fiber reinforced plastic composite structure" after curing, mainly used for rough anti-corrosion of steel pipes. The current technical standard for anti-corrosion structures is to apply multiple layers of coating wrapped in glass fiber cloth. The construction process is not only complex and cumbersome, but also ensures the quality of the coating. Epoxy coal tar anti-corrosion steel pipes also require only one layer of coating to be applied before maintenance, which will bring a lot of inconvenience to the construction schedule, especially during the winter maintenance period. Epoxy coal tar anti-corrosion steel pipes may also harm the health of construction personnel by breathing or eating through the process. Epoxy coal tar anti-corrosion steel pipe glass cloth is used to produce a large amount of precision glass fibers, which can easily penetrate the skin, causing pain and suffering. Although the coating is thick paste type, it still contains about 12% volatile solvents. After the coating is cured, it is completely emitted into the air, which is still not suitable for increasingly strict environmental requirements.

　　Where has the time gone? This is a song that is similar to it. People always say hello. Where has the quality gone? Why do you ask this? It must be that poor quality anti-corrosion steel pipe products have flowed into the hands of customers. As our Cangzhou area is a pipeline equipment and production base, the vast majority of epoxy coal tar anti-corrosion steel pipes come from here. It is inevitable that unscrupulous merchants will deliver inferior products to customers. High quality epoxy coal tar anti-corrosion pipes should have excellent adhesion, toughness, moisture resistance, water resistance, chemical resistance, and the ability to prevent various ions from passing through the paint film. They should also have the characteristics of expanding and contracting with the coated object. Epoxy coal tar anti-corrosion coating is composed of two main components: epoxy and coal tar. It is a two-component coating of A (epoxy) and B (curing agent), which has excellent adhesion, toughness, moisture resistance, water resistance, and chemical resistance. It has the performance of preventing various ions from passing through the paint film and has the characteristics of expansion and contraction with the coated object. The paint film never falls off or cracks. Thickness of 0.5-1.0mm. Epoxy coal tar is a cost-effective form of anti-corrosion, and engineering tests have shown that using epoxy coal tar combined with cathodic protection. Oil and gas pipelines have been used for 20 years without any corrosion.
