Large-caliber water supply pipes generally refer to pipes with a diameter of dn560 or more. PE pipes used in China generally have a large diameter of 1200mm. The quality of large-caliber water supply pipes produced by our company exceeds industry standards and meets national standards. At the same time, our company has successively passed the American Standard, Australian Standard, European Standard, International Standard and CE certification. In addition to the size required by the national standard, we can also customize different sizes of super large-diameter water supply pipes according to customer needs, and order production.

Large-caliber water supply pipes are sometimes used for drainage, and their characteristics such as scratch resistance, high ductility, and corrosion resistance are incomparable to traditional cement pipes and ductile iron pipes. The large-diameter drainage pipe is not affected by the geographical environment during construction, and is an ideal pipe for municipal drainage.

Whether it is in engineering construction or machinery manufacturing, steel pipes are inseparable. That is to say, steel pipes play a very important role in people's lives. Without various pipe materials, it would be difficult to carry out various engineering and construction awards in construction. Just like people, the overall role of the inner and outer plastic-coated composite steel pipes in the building is equivalent to the human skeleton. In practical applications, steel pipe is not only as simple as transporting liquids, but also has a good effect on solids, and it is a very economical pipe. Moreover, if steel pipes are used as the building structure, the weight of the project can be fully reduced, and it will be of great help to the saving of metal! Even for mechanized processing, in bridge applications, the construction is convenient, and it will reduce the protection investment and maintenance costs. A more economical manifestation of the development of people's lives. But what are the characteristics of the inner and outer plastic-coated composite steel pipes? 8 Others For plastic-coated steel pipes, as a water supply and drainage professional, they often only apply the pipes without asking others. In fact, the problem of plastic-coated steel pipes is not entirely in the production of qualified products. In addition, there are service problems. Repair and overcoating of plastic-coated steel pipes, etc. Plastic-coated steel pipes will be damaged during transportation, handling, loading and unloading, construction and installation, causing local defects. For this, local repairs should be made to the defective parts. The plastic-coated steel pipe manufacturer you choose should have this The condition is that if the defect is not repaired, the collapse of the pipe must be here.

Coating varieties: thermoplastic polyethylene powder (PE), thermosetting epoxy resin powder (EP) and other powder coatings. Product characteristics 1. Hygienic, non-toxic, non-scaling, no microorganisms, and fluid quality guaranteed 2. Chemical resistance and soil resistance Corrosion with marine organisms, resistance to cathodic stripping 3. Mature installation process, convenient and fast, and similar to ordinary galvanized pipe connection 4. Good weather resistance, suitable for harsh environments such as deserts and saline alkali 5. Smooth pipe wall, improve transportation efficiency, and service life long. Large-caliber plastic-coated steel pipes have smooth and clean pipe walls, good drainage performance, low fluid resistance, and non-scaling are the best advantages compared to other pipes, which can greatly reduce losses. At the same time, the linear expansion coefficient of the large-diameter plastic-coated pipe is very small, which makes it very advantageous as a main water pipe, which greatly overcomes the defect of large linear expansion coefficients of other plastics and ordinary pipes. Large-diameter plastic-coated steel pipe is an upgraded version of traditional steel-plastic pipe and galvanized pipe with high cost performance. It has the comprehensive characteristics of high strength, high extensibility, good low temperature brittleness, small expansion coefficient of steel pipe, and plastic pipe corrosion resistance, abrasion resistance, and low fluid resistance. It is a new type of water supply and drainage, anti-corrosion green Large-caliber pipes are being used more and more widely in various domestic industries.
