Buried pipelines coated with oil, wrapped with cloth, anti-corrosion steel pipes, epoxy coal tar anti-corrosion steel pipes for external processing by manufacturers

Description :

　　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.

　　Composition: The components are epoxy coal tar primer and topcoat, both of which are mainly composed of epoxy resin and coal tar as film-forming materials, and are made by adding various anti rust pigments, insulating fillers, toughening agents, leveling agents, diluents, anti settling agents, etc. Component B is a modified amine curing agent or a curing agent as the main material, and is made by adding pigments and fillers. When this product is sold, components A and B are supplied together. During construction, they are mixed in proportion and mixed evenly before being used up within the specified time.

　　Product Introduction of Epoxy Coal Tar Anti Corrosion Steel Pipe: It is divided into epoxy coal tar primer and topcoat, both of which are mainly made of epoxy resin and coal tar as film-forming materials, with various anti rust pigments, insulating fillers, toughening agents, leveling agents, diluents, anti settling agents, etc. added. Component B is a modified amine curing agent or a curing agent as the main material, with added pigments and fillers. When this product is sold, components A and B are supplied together. During construction, they are mixed in proportion and mixed evenly before being used up within the specified time. And exported to countries and regions such as Southeast Asia and the Middle East, enjoying a high reputation in domestic and international markets. We adhere to the business philosophy of honesty and trustworthiness, and strictly control the quality of our products; Explore and innovate, strive to improve product production technology. Epoxy coal tar coatings are divided into two types based on their functional applications: epoxy coal tar primer and epoxy coal tar topcoat. Our company's epoxy coal tar primer is a solvent based product; Epoxy coal tar surface paint is a series of products. The composite use of paint and fiberglass cloth can enhance the mechanical properties of the anti-corrosion layer. 2. Room temperature coating, natural curing, easy to apply, can be manually or mechanically applied, especially suitable for on-site use.

　　We strictly demand ourselves to strive for excellence in every product we produce, and the pursuit of customer satisfaction is our unremitting goal. Customer needs are the company's unwavering pursuit. We adhere to the business philosophy of honesty and trustworthiness, and strictly control the quality of our products; Explore and innovate, strive to improve product production technology. We hope that through our efforts and with your support, we can jointly write a beautiful tomorrow for Longdu. IPN8710 non-toxic drinking water anti-corrosion coating is a non-toxic drinking water coating with good anti-corrosion performance. Welcome to discuss the anti-corrosion steel pipe for underground tap water. Cangzhou Longdu Pipeline Co., Ltd. IPN8710 non-toxic drinking water pipeline anti-corrosion steel pipe Overview: There are many types of corrosive media in the water supply pipeline, including acid, alkali, salt, oxidant and water vapor. The coating must have chemical inertness, acid alkali salt corrosion resistance, dense structure, good waterproof permeability, strong adhesion, toughness and fullness

　　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. The overall stress performance of the layer is improved by hanging a mesh to prevent falling. During construction, steel wire mesh is attached to the inner wall of the pipeline and short steel bars are spot welded to make the mesh firmly adhere to the pipe wall. This indeed enhances the bonding force between the lining layer and the pipe wall in practice, as its support and stability to the mortar layer are obvious. In destructive treatment tests on the lining layer, its adhesion is significantly improved compared to not hanging the mesh, and it is also difficult to use steel chisels to break it. This has made significant progress in the stability performance of thicker lining layers. After the completion of construction, improper maintenance is usually carried out. In summary, the anti-corrosion process of cement mortar lining. Shrink the thicker cement mortar layer and produce cracks. The construction of large-diameter steel pipe lining this time is an important measure to enhance the bonding force between the mortar layer and the pipe wall, which is beneficial for both new and old pipelines, saves money on corrosion prevention, ensures safe water supply, and provides services. It is a corrosion prevention method that is in line with China's national conditions and has value for promotion and application. The components are epoxy coal tar primer and topcoat, both of which are mainly composed of epoxy resin and coal tar as film-forming materials, and are made by adding various anti rust pigments, insulating fillers, toughening agents, leveling agents, diluents, anti settling agents, etc. The B component is a modified amine curing agent or a curing agent as the main material, and is made by adding pigments and fillers. When this product is sold, components A and B are supplied together. During construction, they are mixed in proportion and stirred evenly. Within the specified time, the holding life can reach more than 50 years, which is 3-4 times longer than that of traditional trench laying and overhead laying. 4. Pipeline anti-corrosion. Less land occupation, faster construction, and unfavorable environmental protection. Directly buried heating pipelines do not require the construction of large trenches for corrosion prevention. Instead, the anti-corrosion pipes are buried in the dark, which greatly increases the land occupation of the project, increases the excavation volume by more than 50%, and increases the construction and concrete volume by 90%. At the same time, the processing of anti-corrosion pipes and the excavation of trenches on site can shorten the construction period by more than 50% only through on-site exploration.
