FAQ
1.Dab tsi yog txoj kab uas hla ntawm API 5CT?
Txoj kab uas hla ntawm API 5CT C90 casing los ntawm ntau yam kev qhia tshwj xeeb, nrog cov kab dav dav dav (OD) xws li 114.3 hli txog 508 hli (kwv yees li 4-1 / 2 ntiv tes rau 20 ntiv tes), tsim nyog rau cov roj thiab roj qhov xav tau ntawm qhov sib txawv thiab qhov siab.
2.Qhov loj npaum li cas yog API casing
API 5CT C90 casing muaj ntau qhov tshwj xeeb me me kom tau raws li qhov xav tau ntawm engineering sib txawv ntawm cov roj thiab cov qhov dej. Nws sab nraud txoj kab uas hla (OD) feem ntau yog li ntawm 114.3 hli txog 508 hli (kwv yees li 4-1/2 ntiv tes rau 20 ntiv tes), thiab phab ntsa tuab thiab ntev kuj tuaj yeem kho raws li API 5CT tus qauv.
Qhov ntev feem ntau ua tau raws li R1 (4.86-7.62 meters), R2 (7.62-10.36 meters), lossis R3 (10.36-13 meters) cov qauv. Cov txheej txheem kev sib txuas muaj xws li xov hom xws li STC, LTC, BTC, thiab lwm yam, uas haum rau qhov sib txawv ntawm qhov siab ntawm qhov dej ntiav mus rau qhov tob tob.
3.Dab tsi yog qhov kam rau ua API 5CT casing?
Outer Diameter (OD) Tolerance: Rau lub tes tsho nrog ib txoj kab uas hla sab nraud Ntau dua lossis sib npaug li 4.5 ntiv tes (kwv yees 114.3 mm), qhov kev tso cai tso cai yog -0.5% rau +1% ntawm nominal txheej kab.
Phab ntsa Thickness kam rau ua: Qhov tso cai sib txawv ntawm lub tes tsho phab ntsa thickness yog -12.5% to + unlimited zoo kam rau ua (feem ntau yog tswj los ntawm cov chaw tsim tshuaj paus), txhais tau tias qhov tsawg kawg nkaus phab ntsa thickness yuav tsum tsis pub tsawg tshaj li 87.5% ntawm tus nqi nominal.
Ntev Ntev: Raws li API 5CT kev faib tawm:
R1 (4.86–7.62 m): Tso cai sib txawv +0.03 m
R2 (7.62–10.36 m): Tso cai sib txawv +0.05 m
R3 (10.36–13 m): Tso cai sib txawv +0.05 m.
