Mineral-rich countries, often on the re-ore operations drainage and sewage, the general use of industrial waste water flat flat hose, in order to effectively and stably drainage is the use of high quality PVC lay flat hose. Then choose pvc lay flat hose should pay attention to those?
1. Industrial wastewater contains some organic matter and suspended matter, and some water quality will be weakly acidic, so the drainage must have a certain degree of acid and alkali resistance and corrosion resistance, and the inner wall should be smooth, and the row of small particles will not be hindered.
2. Due to some industrial operating environment, high pressure explosion-proof PVC lay flat hose and high pressure pump with the operation, the pressure should be guaranteed; currently 4 inch high pressure explosion-proof PVC lay flat hose dedicated in the industry, working pressure up to 16 kg, burst pres
3.Lined fire pvc lay flat hose with skin to be strong, thickness is quite, will not leak, seepage phenomenon. The high-strength polyester filaments have high toughness and high tensile strength. Polyurethane lining and high-temperature vulcanization bonding, its double guarantee of characteristics, is more durable than ordinary PVC lay flat hose.
