API 5CT H40 Casing Thiab Tubing
API 5CT H40 OCTG yog dab tsi?
Qib Qib:Nkag mus -theem (Lowest zog).
Yield zog:Yam tsawg kawg ntawm 40,000 psi.
Daim ntawv thov:Siv rau saum npoo casing lossis tubing hauv qhov ntiav, qis - qhov dej siab. Nws yog kev lag luam zoo heev piv rau J55 lossisN80.
Kev tsim khoom:Yuav Seamless (S) lossis Electric Welded (EW).
Chemical Composition & Mechanical Analysis (H40)
API 5CT tsom rau kev txwv tsis pub muaj kev puas tsuaj (Phosphorus thiab Sulfur) rau qib no, vim tias qhov kev xav tau ntawm lub zog yog qhov yooj yim kom ua tiav nrog cov qauv carbon steel.

Specification & Daim Ntawv Loj: H40 Tubing
H40 tubing yog siv rau kev tsim khoom hauv qhov tsawg heev - qhov dej ntiav ntiav.
| Sab nraud Dia (inch) | OD (mm) | Qhov hnyav (lb / ft) | Phab ntsa Thickness (mm) | Xaus kev sib txuas |

| 2-7/8" | 73.0 | 6.40 | 5.51 | NU / EU |
| 3-1/2" | 88.9 | 7.70 - 9.20 | 5.49 - 6.45 | NU / EU |
| 4-1/2" | 114.3 | 12.60 | 6.88 | NU / EU |
Specification & Daim Ntawv Loj: H40 Casing
H40 casing feem ntau yog siv los ua qhov chaw tiv thaiv dej hauv av los ntawm kev sib kis hauv qhov tob tob.
| Sab nraud Dia (inch) | OD (mm) | Qhov hnyav (lb / ft) | Phab ntsa Thickness (mm) | Hom kev sib txuas |
| 4-1/2" | 114.3 | 9.50 | 5.21 | STC / LTC |
| 5-1/2" | 139.7 | 14.00 | 6.22 | STC / LTC |
| 7" | 177.8 | 17.00 - 20.00 | 5.87 - 6.91 | STC / LTC |
| 8-5/8" | 219.1 | 24.00 | 6.71 | STC |
| 9-5/8" | 244.5 | 32.30 | 7.92 | STC |
| 13-3/8" | 339.7 | 48.00 | 8.38 | STC |
| 20" | 508.0 | 94.00 | 11.13 | BTC |
Kev txheeb xyuas cov xim Bands rau H40
Txhawm rau tiv thaiv tsis meej pem ntawm qhov chaw zoo, API siv cov lej tshwj xeeb.
| Yam khoom | Xim ID |
| Lub cev lub cev | Tsis muaj xim Band(Standard) |
| Coupling Lub Cev | Tsis muaj xim Band(Feem ntau tsuas yog dub / ntshiab kua roj vanish) |
| Alternative Marking | Qee zaum cim nrog akua roj vanishlos yog tsuas yog stamped "H40" |
Kev soj ntsuam ntawm API 5CT H40
Txij li H40 yog qib qis - muaj zog, cov kev soj ntsuam xyuas yog cov kev xeem API yooj yim (PSL-1).
Kev tshuaj xyuas qhov muag:Tshawb xyuas qhov chaw sab hauv thiab sab nraud rau qhov tsis xws luag xws li lub qhov dej, khawb, lossis nplai.
Hydrostatic Test:Txhua qhov ntev ntawm cov yeeb nkab raug sim nrog dej ntawm qhov siab (feem ntau 3,000 psi lossis tsawg dua rau H40) kom tsis txhob muaj qhov xau.
Dimensional soj ntsuam:Kev ntsuas sab nraud (OD), Phab Ntsa Thickness, thiab Ntev (R1, R2, lossis R3).
Drift Test:Lub cylindrical mandrel yog dhau los ntawm tag nrho qhov ntev ntawm cov yeeb nkab kom ntseeg tau tias cov cuab yeej tuaj yeem dhau mus tom qab.
Kev tshuaj xyuas xov:Tshawb xyuas xov hlau, qhov siab, thiab taper siv API gauges.
NDT (Yeem rau H40):Thaum cov qib siab dua xav tau 100% NDT, H40 feem ntau tsuas yog xav tau yog tias tau teev tseg los ntawm kev yuav khoom lossis yog tias nws yog Electric Welded (EW) los xyuas qhov vuam seam.

FAQ
Dab tsi yog phab ntsa thickness kam rau ua API 5CT?
Nyob rau hauv API 5CT tus qauv, phab ntsa thickness kam rau ua rau casing thiab tubing yog feem ntau 0 txog -12.5%; uas yog, qhov tsis zoo sib txawv ntawm phab ntsa tuab yog tso cai, tab sis qhov zoo sib txawv tsis yog. Cov nqi tshwj xeeb yog txiav txim siab raws li cov khoom tshwj xeeb thiab qib PSL.
Qhov txawv ntawm API 5CT thiab API 5L yog dab tsi?
API 5CT thiab API 5L yog ob tus qauv sib txawv rau cov khoom siv roj av, ua haujlwm sib txawv: API 5CT siv rau cov kav dej thiab cov raj siv hauv cov roj qhov dej, hais txog kev sib tsoo, kev tiv thaiv corrosion, thiab xov foob kev ncaj ncees; API 5L siv rau cov kav dej saum npoo rau kev thauj mus los, ua qhov tseem ceeb ntawm cov vuam zoo, tawv, thiab lub zog sib xws ntawm qhov ntev.
