What are the requirements of the JDG pipe wall thickness specification?

JDG tubes. 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".

1. The wall thickness standard of JDG pipe is standard, and the allowable deviation is positive or negative, and the thickness reaches the above national standard, and the wall thickness of JDG pipe is evenly between. 2. The specifications of JDG galvanized conduit mainly include: 16, 20, 25, 32, 40, 40, during which the national standard thickness of 16 JDG conduit is, and the national standard thickness of other JDG conduit is.

There are six specifications of JDG KBG pipe specifications, and the thickness corresponding to different specifications is also different, and the thickness is generally from to.

Except for the maximum wall thickness of 16, the rest of the JDG pipes are the largest.

Extended Materials. 1. Pipes are the materials used to make pipe fittings. Different pipe fittings should use different pipes, and the quality of pipes directly determines the quality of pipe fittings.

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 pipe national standard wall thickness standard, the rest; There can be positive and negative deviations, all the thickness reaches the above good, but the current market on the tube is also more, open and dark can be used, can also be pre-embedded. The wall thickness of the JDG pipe is uniform in between.

According to the national standard specification: "CECS 120-2007 Construction and Acceptance Regulations for Socketed Tight Shaped Steel Conduits", in addition to the 16 national standard wall thickness (S), 20, 25, 32, 40, 50 national standard wall thickness (S) is, and the allowable deviation of thickness is: .

JDG pipe (sleeved fixed galvanized steel conduit) is a kind of latest conduit for the protection of electrical circuits. The connecting sleeve and its metal accessories are wires and pipes composed of screw tightening connection technology, without cross-grounding, welding and threading, and the appearance is silvery-white or yellow.

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;

Socket tight steel conduit, wire pipeline construction and acceptance procedures.
