API tubing qhov ntau thiab tsawg yog standardized los ntawm covAPI 5 CTspecification. Tubing yog ntsuas los ntawm nwsSab nraud Diameter (OD), thiab tsis zoo li casing, nws yog cov yeeb nkab uas cov roj thiab cov roj tau ntws mus rau saum npoo.
Thaum API lees paub qhov ntau thiab tsawg ntawm 1.050 "mus rau 4-1/2", feem ntau ntawm cov roj thiab roj qhov dej siv peb "tus qauv" ntau thiab tsawg.

Ntev Ntev
Thaum xaj API tubing, koj yuav tsum qhia meej txog qhovNtau yam. Tubing yog tsim nyob rau hauv tshwj xeeb ntev brackets:
Ntau yam 1:20.0 ~ 24.0 ft (6.10 rau 7.32 m)
Ntau yam 2:28.0 txog 32.0 ft (8.53 rau 9.75 m) -Qhov no yog tus qauv kev lag luam.
Ntau yam 3:38.0 ~ 42.0 ft (11.58 ~ 12.80 m)
Kev sib txuas (Xov) Hom
Qhov loj tsuas yog ib nrab ntawm cov specification; hom xov txiav txim seb cov kav dej txuas li cas:
EUE (Sab Nraud Upset End):Qhov kawg ntawm cov yeeb nkab yog thickened ( chim siab) yog li cov xov muaj zog dua li cov yeeb nkab lub cev. Qhov no yog qhovfeem ntaukev sib txuas rau API tubing.
NUE (Tsis yog-Upset End):Cov yeeb nkab tsis thickened ntawm qhov kawg. Nws yog pheej yig dua tab sis muaj zog sib koom ua ke.
Kev sib txuas hwm hwm:Tshwj xeeb, roj- nruj threads (xws li TenarisHydril los yog Vallourec VAM) siv rau siab - siab los yog deviated qhov dej.

FAQ
Dab tsi yog cov qauv tubing loj?
Standard tubing qhov ntau thiab tsawg (Outer Diameter) yog txhais los ntawm covAPI 5 CTspecification thiab ntau yam los ntawm1.050 nti rau 4-1/2 nti.
Qhov ntau thiab tsawg siv hauv cov roj thiab roj ntau lawm yog:
2-3/8"(60.3 hli)
2-7/8"(73.0 hli) - Cov qauv kev lag luam rau ntau qhov dej.
3-1/2"(88.9 hli)
4-1/2"(114.3 hli)
Dab tsi yog qib API tubing?
API 5CT tubing tau muab faib ua ntau qib raws li lub zog thiab kev pabcuam ib puag ncig:
Tsawg zog (Shallow Wells): H40, J55, K55. (Kev lag luam, kev siv tus qauv).
Lub zog nruab nrab: N80 (N80-1 or N80-Q). (General siab - siv siab).
Corrosion Resistant (Sour Service): L80, C90, T95, C110. (Controlled hardness los tiv thaiv H2S tawg).
Lub zog siab (qhov tob / siab -Siab): P110, Q125. (Maximum load-bearing peev).
