3pe anti-corrosion steel pipe manufacturer integrity comes first

Anti-corrosion steel pipes have the advantages of light weight, light strength, high thermal insulation, sound insulation, flame retardancy, cold resistance, anti-corrosion, non-absorbent, and fast construction. They have become an indispensable material for complete insulation, anti-corrosion, waterproofing, sealing and sealing in industries such as construction, transportation, petroleum, chemical industry, electric power refrigeration and so on. Anti-corrosion steel pipes are used in anti-corrosion and cold insulation projects for various indoor and outdoor pipes, including heating pipes, local air-conditioning pipes, chemical industry and other industrial pipes. Overview: Since the birth of synthetic materials in the 1930s, foamed anti-corrosion pipes have been rapidly developing as an excellent thermal insulation and anti-corrosion material. Suitable for various heating, cooling, oil, steam and other pipelines. It is widely used in various pipelines such as heating, cooling, oil and steam.
The advantages of pipeline anti-corrosion can significantly reduce project costs. Based on comprehensive calculations, double-tube heating pipes, the use of fiberglass as the protective layer and the use of high-density polyethylene as the protective layer can generally reduce the project cost. Heat consumption is low and energy is saved. Its thermal conductivity is b/??, which is much lower than other pipeline anti-corrosion materials commonly used in the past, and its anti-corrosion effect is ~ times improved. Furthermore, its water absorption rate is very low, about /. The reason for the low water absorption is because the foam has a high closed cell ratio. Low thermal conductivity and low water absorption, combined with high-density polyethylene or fiberglass protective shells with good anti-corrosion layer and surface waterproofing properties, have changed the situation of traditional trench-laying heating pipes wearing wet cotton jackets, greatly increasing the overall heat dissipation of the heating pipes. The heat loss of the heating network is less than the overseas standard requirements. Anti-corrosion, good insulation performance and long operating life. Because the rigid foam anti-corrosion layer is tightly bonded to the outer skin of the steel pipe, it blocks the penetration of air and water and can provide excellent anti-corrosion effect. At the same time, its foaming holes are closed and its water absorption is very small. Both high-density polyethylene shell and fiberglass shell have excellent anti-corrosion insulation and hysteresis properties. Therefore, the outer skin of the working steel pipe is well protected by external air and water. As long as the internal water quality of the pipeline is well treated, the operating life can reach more than 10 years, which is ~ times longer than the operating life of traditional trench laying and overhead laying. Pipeline corrosion protection. It occupies less space, is quick to construct, and is conducive to environmental protection. The anti-corrosion of directly buried heating pipes does not require the construction of huge trenches. Only the anti-corrosion pipes must be buried in the dark. This greatly increases the project area, increases the amount of earthwork excavation, and increases the amount of civil masonry and concrete. At the same time, anti-corrosion pipe processing and on-site trenching are carried out in parallel. As long as on-site inspection is carried out, the construction period can be shortened by more than approximately.
The anti-corrosion structure of the anti-corrosion steel pipe is a polyethylene three-layer structure with a protective layer also known as three layers/. It is an advanced external anti-corrosion technology introduced from China in recent years. Its structure consists of the following three layers: the bottom layer is fused epoxy, the middle layer is adhesive, and the surface layer is extruded polyethylene. The three-layer anti-corrosion layer combines the interfacial properties and chemical resistance properties of the epoxy coating with the mechanical protection properties of the extruded polyethylene anti-corrosion layer, thereby significantly improving the performance of each. According to relevant information, three layers can extend the service life of buried pipelines to years. This anti-corrosion coating is widely used in long-distance oil and gas pipelines. Sintered epoxy powder is a production process that uses thermosetting powder coating to form a film by spraying it once. It has extremely superior anti-corrosion properties, good chemical corrosion resistance, high bonding strength with the base material, smooth surface, wear resistance and high temperature resistance, and a service life of more than 10 years. During coating, it fully melts and flows, leveling and covering the surface of the steel pipe. There is no gap between it and the base material, and it is completely tightly combined. A chemical reaction occurs during the process. The epoxy powder resin is cured by heat and cross-linked to form a continuous thermosetting polymer, and The steel pipe forms a certain degree of chemical bond, which determines its excellent anti-corrosion layer originating from the crossing project. Anti-corrosion steel pipe coating is a three-layer polyethylene anti-corrosion coating. It is a new anti-corrosion steel pipe coating produced by cleverly combining the European anti-corrosion layer and the epoxy powder anti-corrosion steel pipe coating B widely used in North America. It has been recognized and used around the world for more than ten years.
The coating of anti-corrosion steel pipes is an epoxy powder anti-corrosion coating that is in contact with the bottom layer and the surface of the steel pipe, and the middle layer is a copolymer adhesive with branched structural functional groups. The surface layer is high-density polyethylene anti-corrosion coating. Anti-corrosion steel pipes have always been recognized by us and are widely used. However, in order to better meet people's needs, anti-corrosion steel pipes have been constantly researching and developing new technologies. Anti-corrosion steel pipe manufacturers have successfully integrated the most technological nanotechnology and anti-corrosion steel pipes in recent years. together.
