Is the electric pipe used with steel pipe or PVC pipe?
Non explosion area can be KBG pipe or PVC tube, the former is higher cost, but the installation is firm, the latter is low cost, easy to construction, and in the rain where it will not rust, but compared to the KBG pipe may be damaged.
The explosion-proof area shall be galvanized steel pipe and explosion proof flexible pipe (used for front end equipment connection);
In industrial designs, galvanized steel tubes are generally used for laying electric tubes, especially in the case of explosion protection.The benefits of galvanized steel pipe is not easy to damage, can prevent the destruction and damage of environmental forces to a certain extent, a junction box, check for export, export lines and other accessories, construction and maintenance in explosion-proof environment can be exempted from hot work. The disadvantage is higher cost.The PVC tube is less costly, but less impact resistant.
When the electric wire pipe is laid, the steel pipe can be adopted, or the plastic pipe can be adopted, but the steel tube must not be used in the ceiling. The standard explanation is for rat bite.
