Home piping In the construction process, it is not just a simple installation. There are many things to pay attention to. If you do not pay attention in the construction process, the subsequent project will fail, Domestic pipeline manufacturer Here, I will discuss with you the key points of pipeline construction and installation. Let's look down:

There are three main connection modes of water pipes: sealing rubber ring, bonding and flange connection. The rubber ring interface is generally used for pipes with pipe diameter of 100 mm or more; For pipes with a pipe diameter of less than 100mm, adhesive joints are generally used, and some flexible joints are used. When crossing sewers or other pipelines, metal pipes are generally used. At this time, plastic pipes and metal pipes are connected by flanges, and the connection between the front and back of the valve and the pipeline is also flange connection.

one When solvent bonding is used for small diameter pipes, the socket shall be rounded off to form a groove, and the fracture shall be flat and vertical to the axis, so as to ensure firm bonding and avoid water leakage.

2. Generally, water pipes with a pipe diameter of 100 mm or more use a rubber ring interface. Before installation, personnel should be arranged to chamfer the pipe socket and check whether the rubber ring is qualified. During installation, the socket and rubber ring should be wiped clean.

3. Tradition Pipe installation The excavation of the pipe trench only requires that the pipes can be put into the pipe trench and sealed. When the original soil layer is not loosened, the cushion can not be compacted with pressure.

4. Generally, the branch pipe of water pipe can be split with a tee or a vertical water stop bolt. During construction, a saddle shaped fitting and a half of a two-way tee can be added and clamped with a U-shaped bolt, so that the pipe wall is thickened, and then directly drilled and tapped, and then connected with an externally threaded plastic part. The test shows that the pressure test acceptance after construction by this method can meet the requirements of the specification, In addition, thrust piers shall be set at the places where the water flow in the pipe generates thrust, such as elbows, tees and pipe end sealing plates, to bear the thrust of water flow.

5. As a new type of non-metallic pipe, the water pipe can not be detected by the existing metal pipe detection equipment, but if a wire is buried on the pipe during the pipe laying construction, this problem can be easily solved.
