PVC pipe

Description

The connection methods of PVC pipe mainly include seal rubber ring, bonding and flange connection. Rubber pipes are generally used for pipes with a diameter of 100mm or more; adhesive joints are generally used for pipes with a diameter of less than 100mm, and some are also used with loose joints.

The connection methods of PVC pipe mainly include seal rubber ring, bonding and flange connection. Rubber pipes are generally used for pipes with a diameter of 100mm or more; adhesive joints are generally used for pipes with a diameter of less than 100mm, and some also use loose joints. When pipes cross the sewer or other pipes, metal pipes are generally used, and plastic pipes and metal pipes are flanged. The connection between the valve and the pipeline is also flange connection.

When the small-diameter pipe is selected by solvent bonding, the socket must be rounded to form a bevel. And ensure that the fracture is flat and vertical axis, so that the adhesion can be strong and prevent water leakage. Generally, PVC pipes with a pipe diameter of 100mm or more are selected with rubber ring joints. Before installation, it is necessary to organize personnel to chamfer the pipe socket, and check whether the quality of the rubber ring is acceptable. It is necessary to clean the socket and rubber ring during installation.

Generally, the PVC pipe branch pipe can be opened and opened by i-way or vertical water stopper. During construction, you can add a saddle-shaped fitting, half a two-in-one tee, and tighten it with a U-shaped bolt. This thickens the pipe wall, and then drills directly on it, and then uses externally threaded plastic parts to connect it. Experiments indicate that the pressure test acceptance after construction using this method can fully meet the requirements of the specification. In addition, the position of thrust generated by the water flow in the tube. For example, the elbows, tees, and pipe end sealing plates should be provided with thrust piers to withstand the thrust of the water flow.
