JDG national standard pipe specification table? JDG pipe wall thickness specification table?

JDG tubes. is to replace PVC pipes.

and SC pipes and other types of traditional wire and conduit replacement products, is a breakthrough in the field of building electrical using new materials, new technologies.

JDG pipes are made of galvanized steel.

and the crossover grounding wire of thin-walled steel pipes.

It overcomes the shortcomings of complex construction and large construction loss of ordinary metal conduit, and also solves the problems of poor fire resistance and difficult grounding of PVC pipes.

<> because the cost of JDG pipes has increased compared with ordinary pipes, it is mostly used for integrated wiring in construction.

Fire wiring and other construction.

There are six specifications of JDG tube: 16mm, 20mm, 25mm, 32mm, 40mm, 50mm

According to the national standard specification: "Socketed Tight Setting Steel Conduit Wire Pipe Road Construction and Acceptance Regulations CECS120:2000" indicates that the wall thickness (S) of JDG sleeved Tight Setting Steel Conduit is, and the allowable deviation of thickness is: .

JDG tubes. Specifications Model Allowable deviation of wall thickness is indicated in accordance with the standard "Regulations for the Construction and Acceptance of Socketed Steel Conduit Wire Pipelines CECS 120-2007".

The national standard thickness of 16 JDG threading pipe is, and the other 20 25 32 40 50JDG threading pipe national standard thickness is.

1. JDG pipe national standard wall thickness standard, the rest mm; It is good to have a positive and negative difference, and all the thickness reaches the above, but at present, there are more JDG tubes on the market, and the open and dark applications are available, and they can also be pre-embedded. The wall thickness of the JDG pipe is uniform in between.

2. The diameter and wall thickness of the JDG pipe model have been indicated; As:; The first two data are the diameter, and the last two are the wall thickness;

3. The wall thickness standard of the national standard for galvanized wire pipe can be checked: the special requirements for conduit for electrical installation are GB; Technical requirements for conduits for electrical installationGB; Construction and acceptance of wires and pipelines in the sleeve of tightened steel conduits, CECS 120-2007;

Six sizes. JDG pipe specifications and models.

Details: JDG pipe wall thickness is: mm, 1There are non-standard national standards in the 5 types of JDG pipes with 5 wall thicknesses.

The original length of JDG pipes is 4m and 3m. Six sizes.

The wall thickness of the national standard JDG pipe is milli rolling auspicious meters, and the wall thickness of the non-standard JDG pipe can be used for laying and home improvement ceiling paving.

There are six specifications of KBG pipe specifications, and the thickness corresponding to different specifications is not the same, and the thickness is generally from to. In fact, the requirements of the age of noisy body still depend on the requirements of the construction site and what to use it for.

JDG pipe is a replacement product that replaces various traditional wire conduits such as PVC pipes and SC pipes, and is a breakthrough in the field of building electrical using new materials and technologies.

JDG pipe adopts galvanized steel pipe and thin-walled steel pipe crossover grounding wire, which overcomes the shortcomings of complex construction and large construction loss of ordinary metal conduit, and also solves the problems of poor fire resistance and difficult grounding of PVC pipe.

Because the cost of JDG pipes has increased compared with ordinary pipes, it is mostly used in the construction of integrated wiring, fire wiring and other construction.

There are six specifications of JDG tube: 16mm, 20mm, 25mm, 32mm, 40mm, 50mm

According to the national standard specification: "Socketed Tight Setting Steel Conduit Wire Pipe Road Construction and Acceptance Regulations CECS120:2000" indicates that the wall thickness (S) of JDG sleeved Tight Setting Steel Conduit is, and the allowable deviation of thickness is: .

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.

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 wiring 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 joint, and the process is the same as that of the conduit and the straight pipe joint.

The main connection method.

1) Pipe-to-tube connection: first insert the conduit and the straight pipe joint tightly and position, and continue to tighten the set screw with a set wrench until the "neck" is broken.

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.

JDG pipe specifications are available, and the thickness of each specification is also different.

I don't know, it's too difficult, you can ask someone and see how they come back. I'm so hard, I'm so sad.

Don't wait, you can't wait for the goddess.

Congratulations to the POS female model, Tete Tou, Mu Mu Xiaoxiao, the rain has not stopped.

JDG pipe national standard wall thickness standard, the rest mm; There can be a difference between plus and minus. JDG pipe series products are designed and produced in accordance with GB and GB standards according to the national standard "Special Requirements for Conduits for Electrical Installation".

The main specifications of JDG pipes are: 16, 20, 25, 32, 40, 50, during which the national standard thickness of 16 JDG threading pipes is, and the national standard thickness of other JDG threading pipes is.

According to the standard specification:

The thickness of the JDG pipe is that there can be a positive and negative difference, that is, the thickness of the pipe should reach above.

The wall thickness of JDG pipe is:
