PVC pipe is divided into two kinds of PVC water pipes and drains, for municipal water supply and drainage, industrial water supply and drainage, civil water supply and drainage, irrigation, vegetation watering. There are three main ways to connect PVC pipe: sealant, bonding and flange connection. Pipe diameter greater than or equal to 100 mm pipe commonly used apron interface; pipe diameter less than 100 mm generally use adhesive joints, and some live joints. Pipelines in the sewer or other pipelines, the general use of metal pipe, then the plastic pipe and metal pipe flange connection. Valve before and after the connection with the pipeline are also used flange connection. 1 When small-diameter pipe is solvent-bonded, the socket should be rounded down to form a bevel, and to ensure a smooth and vertical cross-section, so that it can be firmly adhered to prevent water leakage. 2 General PVC pipe diameter greater than or equal to 100 mm are used apron interface. Personnel must be arranged before the installation of chamfering pipe socket parts, but also check the rubber ring quality is qualified. Installation must be sockets, rubber ring and other clean. 3 traditional pipe trench installation trench only requires the pipe into the trench can be sealed and can be, without loosening the original soil, you can not compress the ram. 4 General PVC pipe branch can be used to open three-way or vertical water stop bolt split. In the construction of a saddle-shaped parts can be added a couple of three-way, and with the U-shaped bolt tight, so that thickened the pipe wall, and then drill directly in the open teeth, and then threaded plastic parts out. Tests show that with this method after construction pressure test acceptance can meet the requirements of the specification.
