API 5CT K55 BTC Casing Pipe
API 5CT K55 BTC Casing Pipe yog dab tsi?
API 5CT:Cov txheej txheem thoob ntiaj teb tau teeb tsa los ntawm American Petroleum Institute rau casing thiab tubing siv hauv cov roj thiab cov qhov dej.
K55 Qib:Qib nruab nrab -lub zog carbon steel. Thaum nws lub zog tawm los (55,000–80,000 psi) zoo ib yam rau qib J55,K55 muaj lub zog tensile tsawg dua (Ntau dua lossis sib npaug rau 95,000 psi). Qhov no ua rau nws muaj kev nyab xeeb rau cov qhov tob tob uas qhov hnyav ntawm cov yeeb nkab hlua yog qhov tseem ceeb.
BTC (Buttress Xov Txuas Txuas):Ib tug trapezoidal (lub taub qab-zoo li tus) xov tsim. Nws yog engineered los muab siab axial tensile lub zog, ua rau nws zoo heev rau ntev, hnyav casing hlua. Nws tseem nta "yooj yim stabbing" thaum lub sij hawm sib dhos txheej txheem.
Casing Tube:Muab tso rau hauv lub borehole kom stabilize lub qhov dej, cais cov formations sib txawv, tiv thaiv lub cev qhuav dej, thiab tiv thaiv dej hauv av los ntawm kev sib kis.

FAQ
Qhov txawv ntawm J55 thiab K55 yog dab tsi?
A: Lawv sib koom tib lub zog tawm los, tab sisK55 muaj zog tensile ntau dua(95 ksi vs . 75 ksi). K55 muaj kev nyab xeeb dua rau cov hlua hauv qab nruj dua.
Vim li cas thiaj xaiv BTC hla STC/LTC?
A: BTC (Buttress)muaj superior axial tensile lub zog thiab tuaj yeem txhawb ze li 100% ntawm cov yeeb nkab lub cev load. Nws yog qhov zoo dua rau qhov dej tob thiab loj - txoj kab uas hla.
Puas yog K55 haum rau H2S ib puag ncig?
A: Tsis muaj.Nws yog tus qauv carbon steel. Rau kev pabcuam qaub, koj xav tau qib L80, C90, lossis T95.
Koj puas txhawb Third-Party Inspection (TPI)?
A: Yog, peb txais tosSGS, BV, lossis Intertektxhawm rau txheeb xyuas EMI, UT, thiab Hydrostatic tests ntawm peb qhov chaw.
Qhov siab tshaj plaws qhov tob rau K55 yog dab tsi?
A: Feem ntau rau qhov dej mus txog2,000-3,000 m, nyob ntawm OD thiab phab ntsa thickness.
