Sleeve connection: only for non-galvanized pipes with dark piping and wall thickness greater than 2mm. The length of the bushing is 2.2 times the diameter of the connection pipe; the opposite end of the connection pipe mouth should be in the center of the bushing, and the weld joint should be welded firmly and tightly.

Metal pipes are not allowed to be welded to each other. Galvanized and steel pipes with a wall thickness of 2mm or less must not be connected by sleeve welding.

Galvanized steel conduits and flexible conduits must not be welded with jumper ground wires. The ground wires are made of soft copper wires with a cross-sectional area of not less than 4mm2, and special ground cards are used for jumper connections.

b. Connection of tube to box and box

The openings of boxes and boxes should be neat and match the pipe diameter. One pipe and one hole is required, and no long holes are allowed. It is strictly forbidden to use iron and gas welding to make holes in iron boxes and boxes.

The tube entry position should be arranged behind the second-layer board of the box. The cross-ground wire should be welded to the ground flat steel reserved for the concealed electrical box. The cross-ground wire of the tube and box can be welded to the concealed box. ~ 3 buckle.
