Questions about explosion-proof flexible hoses
Thread Content
I would like to ask whether explosion-proof connectors are still required after using explosion-proof flexible hoses for the connection of instruments on site. If not, is this specified explicitly in these standards? Thank you!
An explosion-proof flexible hose is used; if an explosion-proof connector is not used, does the explosion-proof flexible hose still have explosion-proof properties?
Don’t the connectors at both ends of the explosion-proof flexible hose meet the requirements? Is it necessary to install an additional explosion-proof connector? Another question: is the explosion-proof connector the same as the explosion-proof sealing connector?
The domestic standard requires the use of explosion-proof flexible hoses, but the European standard does not require them. Currently, there is controversy in China regarding the use of explosion-proof flexible hoses for explosion protection. In my opinion, explosion-proof flexible hoses are not necessary, but explosion-proof connectors must be used. Function of explosion-proof flexible conduit: It separates the space for running control cables from hazardous areas. It is effective only when used in combination with other explosion-proof materials such as steel pipes and explosion-proof cable glands. Function of explosion-proof connectors: To isolate explosive ignition sources such as instruments or wiring terminals from hazardous areas. This post was last edited by MLZJ on 2008-1-23 08:54.]
