Tsis tas li ntawd, txoj hlua khi muaj zog npaum li cas? IMC tau teev tseg rau UL ® kev nyab xeeb tus qauv 1242. UL 1242 IMC tus qauv suav nrog ntau qhov kev ua haujlwm raws li qhov yuav tsum tau ua. txhav hlau kav dej tus qauv, suav nrog kev sim beam zog thiab threaded kav dej rub tawm test.

IMC: Tsuas yog Qhov Tseeb.

Dab tsi yog rigid steel?

Rigid hlau Conduit (RMC) yog ib tug tuab-walled threaded tubing, feem ntau yog ua los ntawm coated hlau , stainless hlau los yog aluminium. Galvanized txhav Conduit (GRC) yog galvanized hlau tubing, nrog ib tug tubing phab ntsa uas tuab txaus kom nws yuav threaded. Nws cov kev siv ntau yog nyob rau hauv kev lag luam thiab kev tsim kho.
