Nyob rau hauv xyoo tas los no, thawb haum ncaj couplings tau nrov zuj zus vim lawv txoj kev yooj yim thiab yooj yim ntawm kev siv. Lawv feem ntau siv rau hauv cov ntawv thov hauv tsev thiab kev lag luam, thiab feem ntau yog siv los hloov cov tsoos compression fittings, welded pob qij txha, los yog threaded sib txuas.
Ib qho ntawm qhov zoo ntawm kev thawb hauv kev sib txuas ncaj yog tias lawv tuaj yeem siv rau hauv qhov chaw nqaim lossis nyuaj mus txog qhov chaw, thaum cov pob qij txha ib txwm yuav nyuaj rau nruab. Lawv tuaj yeem siv tau yooj yim thiab nruab nrog ib txhais tes, uas yog qhov tshwj xeeb tshaj yog siv rau hauv qhov chaw nqaim lossis qhov txawv txav.
Lwm qhov zoo ntawm kev thawb hauv kev sib txuas ncaj yog tias lawv cov qauv tsim tuaj yeem tiv taus ntau yam tshuaj thiab cov kuab tshuaj, uas pab tiv thaiv kom tsis txhob xau thiab corrosion mus ntev. Qhov no ua rau lawv muaj kev ntseeg siab thiab ruaj khov rau ntau yam kev siv kav dej.
