Plastic-coated pipes are frequently used in agricultural irrigation, such as water pumps, mobile sprinkler irrigation, high-pressure plastic-coated PVC lay flat hose and so on. Such frequent use is due to the unique properties of plastic-coated pipes. What are the characteristics of high-pressure plastic-coated PVC lay flat hose produced by plastic-coated pipe manufacturers?
Plastic-coated pipes are often called plastic-coated PVC lay flat hose, blue PVC lay flat hose and double-sided PVC lay flat hose in the market. They are a kind of PVC lay flat hose with gum on both sides. They have the properties of wear resistance, corrosion resistance, compression resistance and aging resistance. The structure of plastic-coated pipe includes braided thread and gum. The braided thread is equivalent to the ribs and bones of PVC lay flat hose, which bears the compressive toughness of PVC lay flat hose. The gum is equivalent to the muscle of plastic-coated pipe, which plays a decisive role in the corrosion resistance, wear resistance and aging resistance of PVC lay flat hose. High-strength polyester filament is used as braiding yarn in many plastic-coated pipe products and plastic-coated PVC lay flat hose with high-quality gum has good performance. The so-called high-strength polyester filament yarn is a kind of yarn which is made of yarn with a length of more than 1000 meters, and filaments are wound into groups. It is characterized by high strength, nearly twice as high as cotton and three times as high as wool, which makes the fabric strong and durable, and has strong heat resistance, good elasticity and wear resistance. The high-quality gum of plastic-coated PVC lay flat hose is determined by high-quality raw materials and proportions, which are hard to see as consumers, so we can use some techniques to identify when buying: plastic-coated PVC lay flat hose belt is smooth and gorgeous, soft, non-toxic and tasteless, PVC lay flat hose has no dry cracking degumming, bending PVC lay flat hose or scratching PVC lay flat hose with nails will not. Leave a distinct white mark.
There are many kinds of plastic-coated PVC lay flat hose produced by plastic-coated pipe manufacturers. From the process, there are one-time plastic-coated PVC lay flat hose and two-time plastic-coated PVC lay flat hose, and one-time plastic-coated PVC lay flat hose requires a higher proportion of raw materials; from the working pressure, there are four types, six types, eight types, 10 types, 13 types, 16 types, and above 10 types, the high-pressure plastic-coated PVC lay flat hose can be calculated; from the caliber, there are 1 inch, 1.2 inches, 1.5 inches, 2 inches, 2.5 inches. 3 inches, 4 inches, 5 inches, 6 inches, 8 inches.
