It is very common to use PVC lay flat hose in water supply and drainage operations. Generally, we often divide PVC lay flat hose into Fire PVC lay flat hose and agricultural PVC lay flat hose. Many people are struggling about which kind of good is Fire PVC lay flat hose or PVC lay flat hose. Today we will discuss it.
First of all, there is no big difference between Fire PVC lay flat hose and PVC lay flat hose. The main difference is that Fire PVC lay flat hose is used for fire protection and needs a 3C certification. PVC lay flat hose is not needed. This is an industry certification difference. As for the good use of PVC lay flat hose, it mainly depends on the quality of PVC lay flat hose itself. Fire PVC lay flat hose and PVC lay flat hose in the general market generally have PVC lay flat hose with PVC lining, PVC lay flat hose with polyurethane lining, PVC lay flat hose with synthetic rubber lining and PVC lay flat hose with plastic coating. The common models are 4 types 6 types 8 types 10 types 13 types 16 types with 1-8 inches caliber. The quality of PVC lay flat hose itself should start from two aspects: braided yarn and PVC lay flat hose gum.
PVC lay flat hose braided yarn mainly affects the compressive and wear resistance and toughness of PVC lay flat hose. High-quality PVC lay flat hose braided yarn is usually made of high-strength polyester filament, which is made of yarn with a length of more than kilometers, and filaments are wound into clusters. 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. This kind of filament is often used in the production of automobile seat belts, and its strength and toughness can be imagined.
