PVC Layflat hoses are hoses that deliver water. In fact, pvc is not rubber and should belong to plastic. It is well known that plastics are usually hard and rubber is relatively soft, but this is not absolute. For example, pvc soft rubber is soft.
Although the PVC layflat hose itself looks like a rubber-coated water pipe, it is not a rubber hose. The rubber is divided into styrene-butadiene rubber, natural rubber, silicone rubber, butadiene rubber, etc., nearly 20 kinds. But obviously, PVC does not belong to any of them.
The main component of PVC is polyvinyl chloride, not rubber. The water belt made of polyvinyl chloride lining is called polyvinyl chloride lining water belt, which is characterized by non-toxic, odorless, high pressure resistant and corrosion resistant. Suitable for farmland irrigation, sewage discharge, urban water transport, etc.
Generally, after the installation of the acceptance pvc layflat hose is qualified, the water test will be carried out. Generally, the test of the layflat hose mainly has the following steps:
After the first installation, you can perform a preliminary inspection of the water. When you first open the water control valve, fill the entire pipe, take out the pipe – cut the object, and then plug the end of each pipe.
Followed by the irrigation area as a unit, according to the corresponding water supply pressure, adjust the gate valve, check the joints, whether the pipeline leaks, whether the dripping is uniform, and whether the various instruments are sensitive. If there is a problem, it should be handled in time.
Finally, it is necessary to pay attention to the normal test water after the flat hose is placed, that is, the pipe is refilled. Backfilling should be layered. Fine sand must be used close to the pipe and filled with tamping material to prevent uneven force on the pipe. Winter construction, preferably backfilled in the afternoon to reduce the impact of pipeline expansion on linear changes.
