Internal and external anti-corrosion spiral steel pipe water pipeline three oil and two cloth anti-corrosion manufacturer

Description :

　　Process of epoxy coal tar anti-corrosion steel pipe manufacturer: The epoxy coal tar anti-corrosion coating used for epoxy coal tar anti-corrosion steel pipes mainly consists of two components: epoxy and coal tar. It belongs to two-component coatings, characterized by strong adhesion, toughness, moisture resistance, water resistance, chemical resistance, and the ability to prevent various ions from passing through the paint film. At the same time, epoxy coal tar has the characteristic of expanding and contracting together with the coated object, which prevents the epoxy coal tar coating from falling off or cracking due to pipeline expansion or contraction. Epoxy coal tar anti-corrosion steel pipe is made of various steel pipes such as seamless steel pipe, straight seam steel pipe, spiral steel pipe, etc.

　　The anti-corrosion components of epoxy coal tar 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. Epoxy coal tar anti-corrosion steel pipe primer component A is iron red, component B is black, and the topcoat is black. It has excellent resistance to chemical media corrosion and good physical and mechanical properties, good adhesion, tough coating, as well as excellent electrical insulation and anti permeability, anti stray current and anti microbial erosion. After film formation, it can reduce the number of construction passes. The implementation standards can be divided into the "Technical Standard for Epoxy Coal Tar Anti corrosion Coating of Buried Steel Pipelines" and the "Technical Standard for Liquid Epoxy Coating Internal Anti corrosion Coating of Steel Pipelines". This product is sold with components A and B supplied together, mixed in proportion during construction, and used up within the specified time after uniform mixing. This product is a high-performance anti-corrosion coating with a smooth, dense, and hard coating, strong adhesion, excellent salt alkali resistance, seawater resistance, soil microbial corrosion resistance, and resistance to plant root and stem penetration. The composite use of paint and fiberglass cloth can enhance the mechanical properties of the anti-corrosion layer. Long service life. Room temperature coating, natural curing, easy to apply, can be manually or mechanically applied, especially suitable for on-site use.

　　Epoxy coal tar anti-corrosion steel pipe has chemical corrosion resistance, cathodic stripping resistance, and mechanical damage resistance. Large caliber external epoxy coal tar anti-corrosion steel pipe epoxy coal tar anti-corrosion structure: The anti-corrosion coating made of epoxy resin, coal tar asphalt, and filler is reinforced with glass cloth on the surface of the steel pipe to form an anti-corrosion layer, which is commonly used for external wall anti-corrosion of pipelines. Epoxy powder anti-corrosion steel pipe, aged 40 to 50 years, with high-density polyethylene coating for anti-corrosion. The structure of the high-density polyethylene coating for anti-corrosion is made by wrapping the outer surface of the steel pipe with high-density polyethylene material, which has extremely high mechanical strength and excellent corrosion resistance, and can protect the steel pipe from damage caused by external factors during transportation, installation, and use. Large caliber epoxy coal tar anti-corrosion steel pipes are rust resistant, odorless, and non-toxic after curing. The coating structure is dense, with good waterproof permeability, strong adhesion, and a tough and full coating. Epoxy coal tar anti-corrosion steel pipe is suitable for underground water supply and drainage, underground spraying, positive and negative pressure ventilation, gas drainage, fire watering and other pipe networks in coal mines. However, with the mature technology, strong funds, strong brand influence, and cash of the paint giants, domestic paint companies have been excluded, but their profitability is evident. In terms of external anti-corrosion of epoxy coal tar anti-corrosion steel pipes for water supply, we have eliminated petroleum asphalt external anti-corrosion and uniformly adopted epoxy coal tar anti-corrosion steel pipes.
