JDG pipe national standard? What is the national standard for JDG pipe wall thickness

JDG pipe is also known as "socketed set steel conduit wire pipe", so to check the JDG pipe wall thickness national standard specification, please refer to the "Socket Tight Setting Steel Conduit Wire Pipeline Construction and Inspection Specification CECS 120-2007" specification.

1. The wall thickness specification of JDG pipe national standard, the promise error is positive or negative, and the thickness reaches the above even if it is the national standard, but there are more JDG pipes used on the market at present, and the open and dark compresses are available, and they can also be pre-embedded. The wall thickness of the JDG pipe is uniform in between.

2. The outer diameter and wall thickness of the JDG pipe type have been indicated; As:; Outer diameter + wall thickness 3, JDG pipe technical specifications are implemented in accordance with the "Conduit System for Electrical Installations Part 1"; The inspection specification is based on the "Construction and Inspection of Socketed Tight Steel Conduits, Wire Pipelines, and CECS 120-2007".

Many people do not know the JDG pipe wall thickness specification, in fact, the construction and inspection of JDG pipes have national specifications, and the "Procedures for the Construction and Inspection of Socketed Tight Steel Conduit and Wire Pipelines" are noted in the "CECS 120-2007".

JDG tubes. At present, there is no latest version of the standard, and the JDG pipe wall thickness national standard is still based on the 2007 version of the "Socket Tightening Steel Conduit Wire Pipeline Construction and Acceptance Regulations CECS 120-2007".

The above standards are the JDG pipe acceptance criteria, and the JDG pipe production design standards are based on:

Conduit systems for cable management Part 1 General requirements.

GB Conduit Systems for Cable Management Part 21: Special Requirements for Rigid Conduit Systems.

<> the latest industry standards for JDG tubing.

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".

JDG tube note:

1. The wire must be buried in the wall and must use the conduit, which is from a safety point of view. Usually choose plastic threading pipe or galvanized JDG pipe, both of which are good.

2. When laying wires, you should choose a straight line between two points, do not go around, otherwise the line will simply be messed up, and it is also very troublesome to assume that the demand changes, so it is safest to choose a straight line interval route.

3. Don't break the plug, break the plug, so that it will be inconvenient when you need to repair the circuit in the future.

You have to look up the information or something, because it's too professional I can't remember, or you can take a look.

The version is still right.

Pretty detailed.

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.

The national standard for JDG pipe wall thickness is the national standard thickness; The allowable deviation of the thickness of the wall is 20 specifications, and the allowable deviation of the outer diameter is 0 to negative; national standard thickness; The allowable deviation of the thickness of the state wall line pipe 25 specifications is silver, and the allowable deviation of the outer diameter is 0 to negative; national standard thickness; Allowable deviation of wall thickness Conduit 32 specifications, allowable deviation of outer diameter from 0 to negative; national standard thickness; Allowable deviation of wall thickness Conduit 40 specifications, allowable deviation of outer diameter from 0 to negative; national standard thickness; Allowable deviation of wall thickness Note: = pipe diameter; mm=millimeter; = plus or minus;

At present, there is no standard for the latest version of BAI for JDG pipes, and the national standard for the wall thickness of JDG pipes is still based on the version of DAO in 2007.

JDG Regulation BAI

The allowable deviation of the wall thickness of the grid model is indicated in the "Regulations for the Construction and Acceptance of Socketed Tight DAO Steel Conduit and Wire Pipelines CECS 120-2007".

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.

What is the national standard for JDG pipe wall thicknessKiss! Hello, I'm glad to answer your questions.

The national standard for the wall thickness of the pro-JDG pipe is the national standard for the wall thickness of the pipe, and the allowable deviation is positive or negative, and the thickness reaches the above even if the national standard is the key rock finger, but there are more JDG pipes used on the market at present, and the open and dark compresses are available, and they can also be pre-embedded. The wall thickness of the JDG pipe is uniform in between. The ** of JDG pipe is affected by the outer diameter and thickness, and is also affected by the cost of raw materials.

JDG pipe specifications are 16, 20, 25, 32, 40, 50;The thickness ranges from to, and the specific use scenarios need to be determined according to different requirements. The following are the parts of each specification** :(for reference only) JDG16 pipe, wall thickness, meter strips, strips.
