Tom ntej: H40 Tubing
Txheem:API 5 CT
Qib: H40
Hom:Seamless lossis Welded (EW) Steel Tubing
Kev Siv Tseem Ceeb:Pem hauv ntej, qis- qhov dej siab, cov kab khiav, lossis kev siv tshuab.
Feature tseem ceeb:Covqis tshaj - zog, qib qis tshajhauv API 5CT specification.
Kev piav qhia ntxaws
1. "H40" – Qib Qib
"H": ntseeg tau los ntawm keeb kwm "H- qib" series, nrog "H" tejzaum nws txhais tau tias tus qauv carbon steel qib.
"40": Qhia covyam tsawg kawg nkaus yield zogntawm 40,000 psi (276 MPa). Qhov no yog qib qis tshaj tawm lub zog hauv API 5CT.
2. Cov yam ntxwv tseem ceeb & cov cuab yeej
Qib Siab: Tsawg heev.Nrog lub zog tawm los ntawm tsuas yog 40 ksi, H40 muaj peev xwm txwv kev nro (hook load), sab hauv siab (burst), thiab sab nraud siab (collapse). Qhov no txhais nws daim ntawv thov nqaim qhov rais.
Kev tsim khoom:Nws tuaj yeem tsim tau raws liseamlesslos yogHluav taws xob welded (EW). Qhov kev xaiv EW ua rau nws raug nqi tshwj xeeb - zoo.
Khoom siv:Feem ntau yog ib qho yooj yim carbon-manganese hlau tsis muaj cov ntsiab lus tseem ceeb alloying.
Kev Pab Cuam: TSIS tau.Nws tsis muaj tshuaj lom neeg muaj pes tsawg leeg lossis kev tswj hwm qhov nyuaj rau Sulfide Stress Cracking (SSC) tsis kam.
Hardness:Tsis muaj qhov siab tshaj plaws hardness tau teev tseg hauv API tus qauv rau H40.
3. Kev sib piv nrog Cov Qib Tubing
| Qib | Min Yield zog | Hom Siv Case | Qhov tseem ceeb sib txawv vs. H40 |
|---|---|---|---|
| H40 | 40 ksg | Heev ntiav, benign qhov dej, nto piping | Tsawg zog / nqi.Lub hauv paus. |
| J55 | 5 5 ksg | Dav dav mus rau nruab nrab qhov tob, qis - qhov dej siab | ~ 38% muaj zog dua H40; cov kauj ruam tom ntej mus rau me ntsis xav tau qhov dej. |
| N80 | 80 ksg | Nruab nrab qhov tob / siab, ntau yam | Ob zaug lub zogntawm H40; qhov tseeb workhorse rau mainstream zoo daim ntaub ntawv. |
| L80 | 80 ksg | Kev pabcuam qaub, nruab nrab qhov tob | Tib lub zog li N80 tab sis nrog qhov tseem ceeb SSC tsis kam. |
4. Cov ntawv thov ib txwm
H40 lub zog qis ua rau nws tsis yog-tseem ceeb, qis- daim ntawv thov kev pheej hmoo:
Yooj yim heev, qis-Lub Hwj Hwj Hwj Hwj Hwj Hwj Hwj Hwj Hwj Hwj Hwj Hwj Hwj Hwj Huv:Feem ntau stripper qhov dej los yog qhov dej uas tsis tshua muaj dej ntws.
Flow Lines & Nto Piping:Kev thauj cov hydrocarbons nruab nrab ntawm lub taub hau thiab lub tank roj teeb ntawm qhov tsis tshua muaj siab.
Cov dej tsis huv lossis pov tseg qhov dej:Tsis yog -kev pabcuam hydrocarbon qhov twg corrosion tsawg heev.
Mechanical Applications:Qee zaum siv rau cov hom phiaj (piv txwv li, ncej, lub tes tsho) hauv kev ua haujlwm ntawm cov roj av uas xav tau API traceability tab sis siab ncaj ncees tsis tseem ceeb.
Cov peev nyiaj-Kev txwv, Tsawg- Kev pheej hmoo ua tiav:Qhov twg engineering tsom xam qhia tau hais tias loads deb tshaj H40 lub peev xwm.

Kev txiav txim siab tseem ceeb rau Engineers & Buyers
Kev thov yog qhov tseem ceeb: Tsis txhobxaiv H40 raws li tus nqi ib leeg yam tsis muaj kev ntsuam xyuas cov ntaub ntawv hnyav. Nws cov npoo kev nyab xeeb yog slim.
Corrosion yog ib qho kev txhawj xeeb loj:Nws tsis muaj kev tiv thaiv corrosion los yog alloying rau CO₂ (qab zib corrosion) tsis kam. Poob poob vim yog corrosion tuaj yeem ua rau nws cov phab ntsa nyias tsis zoo.
Tsis yog rau Downhole hauv Modern Wells:Nws siv los ua ib qho tseem ceeb ntawm txoj hlua tubing nyob rau hauv txhua yam tab sis qhov feem ntau ntiav, depleted, thiab benign qhov dej yogtsawg kawg nkausthiab feem ntau poob siab los ntawm tuam txhab qauv.
Purchase Order Clarity:Txawm rau qib yooj yim no, qhia meej:
Txheej txheem:Seamless los yog EW (EW yog pheej yig dua).
Xaus Xaus:Plain kawg, threaded thiab ua ke, los yog chim siab.
Qib soj ntsuam:Feem ntau API Qib Kuv (tus qauv) txaus.
Lub J55 Alternative:Rau kev nce nqi me me,J55muab lub zog ntau dua (55 ksi vs . 40 ksi) thiab yog ib qho kev xaiv ntau dua, kev nyab xeeb dua rau lub teeb- lub luag haujlwm downhole daim ntawv thov.

Nws lub ntsiab kom zoo dua yogtus nqi pib qis, tab sis qhov no los nrog cov kev txwv tseem ceeb hauv lub zog, kev nyab xeeb margin, thiab corrosion kuj.
Cov ntsiab lus
API 5CT H40 tubing yog kev lag luam, qis -lub zog (40 ksi tawm los) carbon steel yeeb nkab muaj nyob rau hauv seamless lossis welded daim ntawv. Nws siv yog txwv rau qhov ntiav heev, qis-siab, tsis yog- daim ntaub ntawv corrosive, feem ntau nyob rau saum npoo los yog nyob rau hauv feem ntau undemanding zoo ib puag ncig.Rau yuav luag tag nrho cov downhole ntau lawm tubing daim ntaub ntawv,J55 lossis qib siab dua yog qhov nyiam heevvim lawv ntau dua kev nyab xeeb margins thiab versatility.
** Hauv qhov tseem ceeb: H40 yog ib qho niche, pob nyiaj siv - qib cov khoom siv rau cov xwm txheej uas suav nrog engineering ua pov thawj dhau qhov tsis ntseeg tias qib siab dua yog qhov tsis tsim nyog. Nws tsis yog qhov dav dav -lub hom phiaj downhole tubing qib.
