How to connect JDG pipes? What is the connection method of JDG pipe

The JDG pipe connection method is:

1. Connection between pipes: first insert the conduit and the straight pipe joint into a firm position, and then fix the screws in the Ye District of Tianjian City Xiwangwei Land Species District until the nut falls off.

In order to ensure a good reading experience, it is recommended not to scale the browser size.

2. The connection between the pipe and the box: unscrew the claw nut of the threaded joint and place it on the inner wall of the junction box, and use a set wrench to clamp the claw nut and the hexagon nut inside and outside the junction box. Then connect the conduit with the other end of the threaded fitting, and the process is the same as the connection between the conduit and the straight pipe fitting.

To be precise, the role of the fasteners and bolts of the JDG pipe and the crimping point of the KBG pipe is for the grounding of the metal steel pipe. The purpose of metal pipe connection is achieved by tightening nails or crimping.

The JDG pipe adopts the sleeve tightening type, and the connection method is to tighten the pipe according to the screws on the pipe fittings, so as to achieve a tight connection. (Convenient construction).

The connection method of SC pipe is threaded connection and traditional casing welded connection, and it is necessary to apply anticorrosive paint (troublesome construction).

When we carry out integrated wiring, we usually use JDG pipes, which are simpler than ordinary metal pipes. In the process of integrated wiring, people usually need to connect JDG pipes and conduits and other items, so what is the connection method of JDG pipes, and then I will briefly introduce it to you.

1. JDG pipe is also known as sleeve tight set galvanized steel conduit, which is a kind of electrical line conduit, and the appearance is mostly silver or yellow. JDG pipe is a breakthrough innovation in the field of building electrical appliances, which overcomes the shortcomings of ordinary metal conduit construction, large loss, poor fire resistance of PVC pipe, and difficult grounding. JDG pipes are mostly used in integrated wiring and other construction.

2. There are two main connection methods for JDG pipes. One is the connection between the straight pipe and the conduit, generally the straight pipe joint has grooves, we insert the two nozzles of the conduit into the groove side of the straight pipe joint, so that the joint of the conduit joint and the straight pipe can be plugged and positioned. There are usually threaded holes at both ends of the pipe joint, we put the set screw into the threaded hole, there is a "neck" at the tightening end of the screw, and we tighten the screw with a set wrench until we break the "neck".

3. Another connection method of JDG pipe is the connection between the pipe and the junction box. Usually the end of the JDG pipe and the wiring and connection, there is a claw nut and a hex nut, we screw the claw nut down first, and then put it on the inner wall surface of the junction box. Next, tighten the claw nut and hexagon nut, respectively, so that the tube and junction box are clamped inside and out.

Finally, we will connect the joints of the conduit and the straight pipe according to the method of tube and tube connection.

When you choose a JDG pipe, don't confuse it with a KBG pipe, generally the wall of the KBG pipe will be thinner, and its connection method is different from the JDG pipe.

Summary. Introduction to the connection method of JDG pipe.

1. Connection between pipes: first plug the conduit and the straight pipe joint into the position, and continue to tighten the set screw with a set wrench until the nut cap falls off.

How to deal with JDG pipe joints?

Introduction to the connection method of JDG pipe 1, the connection between the pipe and the pipe Zen tumbling: first insert the conduit and the straight pipe joint into the smooth pipe joint, and continue to tighten the set screw with a set wrench until the nut cap falls off.

Connection of the joint 1) Straight pipe joint, the connection between the supply pipe and the pipe. There is a groove in the middle of the pipe joint that is pressed out by the rolling process, and the taper formed can make the catheter inserted and positioned to ensure tightness, and the depth of the groove is consistent with the wall thickness of the catheter, which does not affect the threading idea. There is a threaded hole with set screws at each end of the joint.

The set screw is specially made, and the end of the tightening is hexagonal and has a cross groove, and the other end is conical; Near the end of the screw there is a "neck" with a smaller diameter. 2) Threaded joint, the connection between the supply pipe and the box. The end at which the connector is connected to the junction box with a claw nut and a hexagon nut; At one end connected to the conduit, there is a threaded hole with a set screw, and the structural dimensions of the set screw and threaded hole are the same as those of the straight pipe joint.

The connection of the JDG pipe is a tight connection and fixing, and the connecting fittings of the JDG pipe are with set screws (special accessories), and a certain torque must be reached during installation and construction, that is, when screwing, the nut should be screwed until it is dropped, so that the standard torque can be reached. Prevents loosening and ensures a secure connection, eliminating the need for jumper wires.

Let me use the vernacular, the conduit can be connected with the conduit, and if it can't, it can be linked with accessories.
