JDG metal line pipe is an important material used in electrical engineering, with excellent corrosion resistance and electrical conductivity. In the field of electric power, communication, construction, JDG metal line pipe is widely used in the laying and protection of the line.JDG metal line pipe construction process is very important, it is related to the safety and reliability of the line.
1, JDG pipe shall be cut off by toothless saw or hacksaw, the port should be smooth, no burr.
2, JDG pipe laying dark, its bending radius should not be less than 6 times the outside diameter of the pipe, in the concrete plane, its bending radius should not be less than 10 times the outside diameter of the pipe; JDG pipe open laying, its bending radius should not be less than 6 times the outside diameter of the pipe. When there is only one bend between the two junction boxes, the bending radius should not be less than 4 times the outer diameter of the pipe.

3, JDG pipe laying dark, fixed point spacing is not greater than 1000mm, fixed point from the elbow focus, junction box and terminal spacing should be greater than 150mm, and less than 300mm.
4, JDG pipe buried in the wall or concrete pipe and wall or concrete surface clearance should not be less than 15mm.
5, the set of tightly fixed steel conduit pipe laying, its bracket, hanger specifications, when there is no design requirements, should not be less than round steel: diameter 6mm; flat steel: 30mm * 3mm:; Angle: 25mm * 25mm * 3mm of the provisions.
6, pipe into the box (box) should be a pipe a hole, pipe diameter and box (box) knockdown hole should match, is strictly prohibited to open a long hole. Pipe into the box (box) should be neatly arranged, evenly spaced, box (box) and wall flush.
7、After the piping is finished, in order to prevent the foreign matter from entering into the pipe, the end should be well blocked.
8, in the concrete pouring, should leave the electrician to monitor, in order to prevent the pipeline, junction box shock open displacement.
9, to be removed after the completion of the template, should be carried out in a timely manner to pre-sweep the pipe, sweeping the pipe should be fixed on one end of the cloth with the line, from the other end of the pipeline to pull out, to remove due to the galvanized pipeline into the pipe debris or water. Sweep the pipe is completed, close the box mouth.
