Which connection modes are used for PVC hoses？
When solvents are used to bond small diameter PVC hoses, it is necessary to invert small rounded corners at the socket to form grooves, and to ensure that the fracture surface is flat and vertical axis, so as to ensure firm bonding and avoid leakage.
Aprons are usually used for PVC hoses with diameter greater than or equal to 100 mm. Before installation, it is necessary to arrange personnel to chamfer the socket of the pipe and check the quality of the apron. When installing, the socket and rubber ring must be wiped clean.
When traditional plastic pipes are installed, the trench excavation only requires that the pipes can be put into the trench and sealed. When the original soil is not loosened, the cushion can be compacted without pressure.
In general, the opening of branch pipe of PVC hose can be opened by three-way or vertical water stop plug. During construction, a saddle-shaped fittings can be added with half two-in-three connections and clamped with U-shaped bolts, thus thickening the pipe wall, then drilling directly on the top of the teeth, and then connecting with plastic parts with external threads. The test proves that the acceptance of pressure test after construction by this method can fully meet the requirements of specifications. In addition, thrust piers must be installed at the positions where the water flow in the pipe produces thrust, such as elbows, tees and end closures to withstand the thrust of the water flow.
