What is a tight steel tube?
JDG pipe is the replacement of traditional PVC and SC pipes and other traditional wire conduits. It is a breakthrough in the field of building electrical field using new materials and technologies. The JDG pipe adopts the cross connecting ground wire of galvanized steel pipe and thin-wall steel pipe, overcomes the defects of complicated construction and large construction loss of common metal pipe, and solves the problems of poor fire resistance and difficult grounding of PVC pipe. Because the JDG pipe material is more expensive than the ordinary pipe material, it is more used in the construction, such as comprehensive wiring, fire protection wiring and so on.
The tight steel tube is called "galvanized steel pipe with sleeve connection" or "flat pipe of steel metal for electrical installation". JDG. The utility model relates to a novel protective conduit for an electric circuit. The connecting sleeve and the metal accessory are provided with a wire pipeline composed of screw fastening connection technology, and the utility model does not need to do cross grounding, welding and covering, and the appearance is silvery white or yellow.
The fully enclosed steel tube is called "sleeve connection steel pipe". The English abbreviation is JDG. The sleeve between the pipe and the pipe is fastened by screws. The current specification is the construction and acceptance rules of CECS 120:2007 sleeve steel conduit pipe line
