Thawj qhov sib txawv ntawmP110thiabC110casing yog lawv tsim nyog rau corrosive ib puag ncig. Thaum ob qho tib si muaj qhov tsawg kawg nkaus tawm lub zog (110,000 psi),P110 yog qib dav dav - hom phiaj rau qhov tob, siab - qhov dej siab, thaum C110 yog qib tshwj xeeb "kev pabcuam qaub" tsim los tiv thaiv Hydrogen Sulfide (H2S ).
API 5CT P110casingyog ib qho ntawm feem ntau sivsiab -lub zogsteel qib hauv roj thiab roj drilling. Nws belongs rauPab pawg 4raws li API 5CT specification thiab tau tsim tshwj xeeb rau cov qhov dej sib sib zog nqus, siab -siab formations, thiab ib puag ncig uas xav tau huab cua load peev xwm.
Core Positioning: P110 yog qhov dav dav - lub hom phiaj, siab - lub zog steel qib. Nrog rau qhov tsawg kawg nkaus tawm lub zog ntawm 110,000 psi, nws yog qhov kev xaiv thawj zaug rau kev ua haujlwm zoo heev ultra-.
Kev Pabcuam Ib puag ncig: Feem ntau siv hauvtsis yog- ib puag ncig corrosive (Sweet Wells). Txawm hais tias nws muaj zog heev, nws tsis tiv taus Hydrogen Sulfide (H2S) corrosion. Nyob rau hauv ib puag ncig qaub, P110 yog qhov muaj feem cuam tshuam rau Sulfide Stress Cracking (SSC).
Kev kho cua sov: Nws yuav tsum tau puv -ntevQuenched & Tempered (Q&T)kev ua kom ntseeg tau siab toughness thiab ib qho microstructure zoo txawm tias nws lub zog siab.
Daim ntawv thov: Feem ntau siv los ua cov casing los yog nruab nrab casing nyob rau hauv ultra- qhov tob tob (tshaj 4,000 meters) thiab siab - roj thiab roj qhov dej uas yuav tsum tau tiv taus lub siab tseem ceeb thiab tensile loads.

API 5CT C110 casingyog lub siab -kawg,siab -lub zog, qaub- kev pabcuam (corrosion-}resistant)qib steel. Nws belongs rauPab pawg 2(Cov qhab nia txwv tsis pub muaj zog) raws li API 5CT specification.
C110 tau tsim los daws qhov kev sib tw loj hauv kev sib sib zog nqus- txoj kev loj hlob zoo: muab lub zog siab uas yuav tsum tau muaj los tiv thaiv kev kub ntxhov thaum tswj kev tiv thaivSulfide Stress Cracking (SSC)tshwm sim los ntawm Hydrogen Sulfide (H2S).
Core Positioning: C110 tam sim no yog qhov siab tshaj - zog H2S- qib tiv taus hauv API tus qauv. Nws muab lub zog txhua yam ntawm P110 nrog cov qaub- kev pabcuam kev ncaj ncees ntawm L80 thiab T95.
Corrosion Resistance Txoj Cai: Txheem siab - lub zog steels (xws li P110) yog cov tawv heev hauv H2S ib puag ncig vim lawv siab hardness. C110 siv cov alloying meej thiab kev kho cua sov siab heev kom lub hardness nruj me ntsisqis dua 30 HRC, cia nws tawm tsam SSC txawm tias muaj kev ntxhov siab ntau.
Manufacturing Requirements: Nws yuav tsum tau puv -ntevQuenched & Tempered (Q&T)ua. Cov kev cai rau cov khoom siv purity (tsis tshua muaj kev txwv rau Phosphorus thiab Sulfur) yog qhov nruj dua li cov qauv rau qib.
Daim ntawv thov: Feem ntau siv hauv qhov tob, ultra- tob, thiab siab heev -siabqaub roj thiab roj qhov dej(muaj H2S). Thaum lub zog ntawm T95 (95 ksi) tsis txaus los txhawb lub nra ntawm lub qhov dej tob, C110 yog tib txoj kev xaiv zoo.
