API 5CT lub iceg tubing los nrog ntau hom xaus, uas yog qhov tseem ceeb rau kev ua kom muaj kev sib txuas tsim nyog thiab ua haujlwm hauv cov roj thiab roj ua haujlwm. Lub ntsiab ntawm xaus rau api 5ct lub iceg tubing xws li:
Plain Kawg (PE): Hom kawg yog tsuas yog txiav ncaj hla yam tsis muaj lwm yam ntxiv. Nws yog feem ntau siv nyob rau hauv cov ntawv thov uas lub tubing yuav welded lossis txuas nrog siv lwm txoj kev.
Threaded Kawg: Cov xaus no yog machined nrog cov xov tshwj xeeb uas tso cai rau kev sib txuas yooj yim rau lwm lub tubing lossis khoom siv. Cov xov yuav sib txawv raws li cov tseev kom muaj ntawm daim ntawv thov, thiab cov xov Xov Cov Xov Xwm suav nrog:
Eue (Sab Nraud chim kawg): Eue Tubing nta nta tuab phab ntsa ntawm qhov xaus, uas muab ntxiv lub zog thiab kev txhawb nqa piv rau tsis {}} chim siab (nau) tubing. Qhov kev tsim no txhim kho lub qhov muaj peev xwm tiv thaiv qhov siab siab thiab cov xwm txheej hnyav ntsib thaum lub sijhawm khiav haujlwm thiab ntau lawm.
Nue (tsis -} chim kawg): Nue, lossis tsis - chim siab kawg, hais txog ib hom tubing kawg siv hauv cov roj thiab roj kev lag luam, tshwj xeeb hauv api 5ct octog tubing. Tsis zoo li chim siab (EUE), uas muaj ib lub phab ntsa tuab dua ntawm qhov kawg los muab lub zog ntxiv thiab kev txhawb nqa muaj lub zog sib txawv thoob plaws hauv nws qhov ntev. Cov qauv tsim no tso cai rau kev tuav kom yooj yim dua thiab teeb tsa, ua rau nws haum rau ntau yam kev siv hauv kev lag luam thiab kev ua haujlwm ntau lawm.
Coupled Kawg: Hom no cuam tshuam nrog kev siv ntawm txuas txuas mus txuas ob daim ntawm tubing. Qhov txuas txuas tau xov ntawm ob xaus, tso cai rau kev sib txuas nyab xeeb ntawm cov tubing ntu.
TSHWJ XEEB: Ua raws li cov kev cai tshwj xeeb, tej zaum yuav muaj cov kev cai lossis cov kev ntsuas tshwj xeeb tsim rau cov ntawv thov tshwj xeeb, cov uas xav tau kev sib khi ntxiv.
Cov kev sib txawv ntawm qhov xaus tau tsim los ua kom tau raws li kev xav tau ntawm kev xyaum thiab kev ua haujlwm roj ntau heev hauv cov txheej txheem roj thiab roj av, ua kom muaj kev nyab xeeb thiab cov txheej txheem kev nyab xeeb.
