In order to better protect the wire, people often use the pipe to lay the pipe when it is used for hydropower construction. The threading pipe used today is made of PVC. It refers to the wire and cable protection flat pipe used in the industrial and construction engineering below 2000V with polyvinyl chloride resin as the main raw material and other additives added by extrusion molding. So what are the precautions for PVC wire tube construction?

PVC wire pipe construction precautions one

In order to ensure the safety of hydropower construction, there are many aspects that need to be paid attention to during construction. First of all, it should be noted that the transportation, laying, installation and bending of PVC threading pipes and their fittings should be carried out at the permissible temperatures specified in the materials. The joints of the same specification and the ends of the threading pipe shall be sleeved with PVC adhesive at each joint.

When pre-buried construction and wall piping construction in the first-layer electrical piping structure board, the electrical positioning must be marked on the wall surface by the color pen according to the electric map of the house type. After confirming, the PVC threading pipe and the switch box are installed.

After the wire and tube is laid, everyone should also do the investigation. The requirements for construction are: the pipelines should be integrated into one, and there should be no defects such as exposed walls and cracks, holes, and defects in the walls and walls. Everyone should use the lead wire when sweeping the pipe. After the lead wire is threaded through the pipe, the two insulated wires of appropriate section and length should be taken and the pipe inspection should be carried out from the middle.

In addition, when there is a waterproofing request on the sun terrace and the PVC threading pipe in the bathroom floor is blocked, it should be disposed of before the waterproof construction; if the pipe is modified after the waterproof construction, the damaged waterproof layer must be re-constructed. Waterproof works and ensure that the test water passes.
