Common Problems with Anti-Corrosion Steel Pipes

Seamless steel pipes coated with paint should comply with the requirements of GB/T8163. Other types of steel pipe should comply with industry standards. The above describes the capabilities and construction requirements of plastic-coated steel pipes. Pay attention to these issues during installation to ensure proper use. Internally and externally plastic-coated composite steel pipes have been extremely popular since their introduction. They quickly replaced various types of steel pipes, including galvanized steel pipes, stainless steel pipes, copper pipes, and threaded pipes. Their applications have gradually expanded, and they have received enthusiastic acclaim. This is precisely what galvanized steel pipes could not achieve. They address corrosion issues associated with water transport, burial, and acid and salt corrosion, significantly extending their service life. Fire-fighting plastic-coated steel pipes are made by applying a special process to high-frequency welded steel pipes, with a layer of epoxy resin bonded to the inner and outer surfaces at high temperatures.

The following discusses the issue of air holes in plastic-coated steel pipes for water supply applications. It offers numerous advantages, the first of which is its corrosion resistance. Plastic-coated steel pipes are plastic-coated on both the inside and outside of the pipe, making them suitable for transporting highly corrosive fluids and for burial in corrosive environments. Second, steel inventory levels are stable with some decline.

Minqin chemical cleaning of plastic-coated pipes at reasonable prices can achieve a certain degree of surface cleanliness and roughness, but the anchor marks are shallow and can easily contaminate the environment. With its high and low temperature resistance, it is widely used in water supply, industry, fire protection, communications, power generation, and other high-quality construction projects, making it a green product for the 21st century's pipe upgrade. It can be used for heat-resistant corrosion protection of building water supply and drainage pipes, hot and cold water circulation pipes, and can also be used for corrosion protection of steel pipes in seawater circulation systems and chemical systems. It offers strong corrosion resistance, drag reduction, corrosion prevention, pressure resistance, and antibacterial properties, as well as excellent chemical stability and water resistance.

The designated manufacturer of plastic-coated composite steel pipe for fire protection has researched and developed numerous new materials and technologies, particularly in the areas of exterior coating and cladding, corrosion testing, repair, and internal cleaning, providing superior protection for steel pipe safety. Chemical steel pipes are often buried underground. Previous generations of chemical steel pipes could not withstand the harsh operating conditions of such a buried environment, resulting in accelerated aging and even leakage. Plastic-coated steel pipe for chemical applications has changed this situation, and is gaining popularity in an increasing number of chemical plants.

It has become a popular steel pipe material for the chemical industry. The tower is constructed by connecting the tower mast assembly, which is made of steel sections. The surface and interior surfaces of the tower mast sections are hot-dip coated with a modified polyethylene plastic layer. Furthermore, conventional steel pipes can easily rust. The construction procedures for plastic-coated steel pipes should comply with the following requirements: Plastic-coated steel pipes should not be buried within reinforced concrete structures; welding is prohibited during the installation of plastic-coated steel pipes; plastic-coated steel pipes should be installed from large diameter to small diameter, and the pipe ends should be sealed promptly; plastic-coated steel pipes should not be dropped or violently impacted during transportation, loading and unloading, and on-site construction; when installing plastic-coated steel pipes, pipe diameters up to DN50 can be cold-bent using a pipe bender.

Coated steel pipes for underground coal mines: Coated steel pipes for underground coal mines are manufactured by applying a special powdered material to the inner and outer surfaces of base steel pipes through a special process. The resulting composite product boasts antistatic, flame-retardant, and corrosion-resistant properties. This product overcomes the inherent drawbacks of steel pipes, such as susceptibility to rust, corrosion, and high pollution, and the low strength and deformation of plastic pipes. Combining the advantages of both steel and plastic products, it is a key energy-saving and environmentally friendly product for promotional use. It is widely used in the construction of steel pipe systems in power, communications, transportation, municipal administration, and mining throughout China, and is also used as a protective conduit for cables crossing bridges and roads.

Fire-fighting steel pipe is indispensable, and plastic-coated fire-fighting pipe with internal and external coatings is currently the leading product in the fire-fighting pipe industry. Let's discuss the relevant issues before using plastic-coated fire-fighting pipe with internal and external coatings. Before installing fire-fighting steel pipe, it's important to select the appropriate type of steel pipe and research it. A good fire-fighting system relies not only on high-quality steel pipes; other components, such as fire hydrants, must also meet standards. This significantly extends the lifespan of the system. Users should make their selection based on their specific circumstances. All components must be airtight. Procuring these products before installing the steel pipes not only shortens installation time but also saves on labor. Fire-fighting plastic-coated pipe fittings have a smooth inner wall, low friction, and no scaling, while also providing a more aesthetically pleasing and luxurious outer surface.

The inner layer of fire-fighting plastic-coated pipe fittings must be protected against contamination, and comprehensive measures are required. The following details the process: Fire-fighting plastic-coated pipe fittings generally use the same connection method as traditional pipe fittings. The materials and plastic coating layers used are different. Choosing suitable plastic coated steel pipes according to different use environments can greatly reduce the aging speed of plastic coated steel pipes due to the incompatibility between materials and the environment, and increase the service life of the steel pipes.
