API SPEC 5L-2018 (cov lus qhia txog cov yeeb nkab kab), uas tau sau thiab muab los ntawm American Petroleum Institute, feem ntau siv thoob plaws ntiaj teb.

Cov yeeb nkab kab: suav nrog cov yeeb nkab tsis muaj qhov thiab cov yeeb nkab vuam. Cov yeeb nkab kawg muaj cov kawg tiaj tus, cov kawg xov thiab cov kawg qhov (socket); cov txheej txheem txuas yog vuam kawg, txuas txuas, txuas qhov (socket), thiab lwm yam. Cov ntaub ntawv tseem ceeb yog GR.B, X42, X52. X56, X65, X70 thiab lwm yam hlau.

API SPEC5CT-2012 (Casing thiab Tubing Specification) yog sau thiab muab los ntawm American Petroleum Institute (American Petreleum Instiute, hu ua "API") thiab siv rau txhua qhov chaw ntawm lub ntiaj teb.

nyob rau hauv:

Lub plhaub: Ib lub yeeb nkab uas txuas ntawm qhov av mus rau hauv lub qhov dej thiab ua haujlwm ua phab ntsa ntawm lub qhov dej. Cov yeeb nkab txuas nrog los ntawm cov khoom sib txuas. Cov khoom siv tseem ceeb yog cov hlau xws li J55, N80, thiab P110, thiab cov hlau xws li C90 thiab T95 uas tiv taus hydrogen sulfide corrosion. Nws cov hlau qis (J55, N80) tuaj yeem vuam cov yeeb nkab hlau.

Cov kav dej: Ib lub kav dej uas ntxig rau hauv lub plhaub los ntawm qhov chaw hauv av mus rau txheej roj, thiab cov kav dej txuas nrog los ntawm kev sib txuas lossis sib xyaw. Nws lub luag haujlwm yog kom lub twj tso kua mis thauj cov roj los ntawm txheej roj mus rau hauv av los ntawm cov kav dej. Cov ntaub ntawv tseem ceeb yog cov hlau qib xws li J55, N80, P110, thiab C90, T95 uas tiv taus hydrogen sulfide corrosion. Nws cov hlau qib qis (J55, N80) tuaj yeem vuam cov kav dej hlau.
