Quality PVC lay flat hose should have smooth surface, no obvious jump line, uniform thickness, no wrinkle or other defects. Under the action of water pressure, along the direction of water flow, PVC lay flat hose should not produce counterclockwise torsion. PVC lay flat hose should be able to unfold immediately, without crimping, and can be re-tightened without leakage under design working pressure. In accordance with the above points, the quality of PVC lay flat hose can be basically guaranteed, and the specific situation also depends on the use scenario. Large caliber canvas PVC lay flat hose can be used for mine emergency rescue, as emergency drainage pipeline; it can be used for drainage and sewage, oil supply, portable and drainage to bring great convenience; it can also be used for underground water conveyance and slurry transportation, because of its high pressure, easy to roll can reduce the cost of mining waste and improve work efficiency. From the finished product, large-caliber PVC lay flat hose is 6 inches, 8 inches, corresponding caliber is 150 mm, 200 mm, etc., material is polyurethane lining. Also known as polyurethane high-pressure hose, by high-quality polyurethane raw materials and high-strength polyester filament extruded through a single extruder, high temperature vulcanization, with acid and alkali resistance, wear resistance, aging resistance, strong pressure, in the sun protection, freeze resistance and high temperature is a good choice.
