API 5CT L80 Casing Thiab Tubing Pipe yog dab tsi

API 5CT L80 Casing Thiab Tubing Pipe yog dab tsi?

API 5CT L80 Casing thiab Tubing Pipehais txog oilfield casing thiab tubing cov khoom uas ua raws li American Petroleum Institute (API) specification API Spec 5CT. Cov khoom no feem ntau yog siv hauv cov roj thiab roj qhov dej los txhawb cov phab ntsa zoo thiab xa cov kua dej, thiab tshwj xeeb tshaj yog tsim rau cov cheeb tsam corrosive uas muaj H₂S (hydrogen sulfide) lossis CO₂.L80 belongs rau steel qib pab pawg ntawm corrosion-resistant casing. API 5CT L80 oilfield casing yeeb nkab suav nrogL80-1, L80-9Cr, thiabL80-13Cr. L80-1 yog siv nyob rau hauv lubH2S ib puag ncig, thaum L80-9Cr thiab L80-13Cr yog siv nyob rau hauv lubCO2 ib puag ncig. Nyob rau hauv ib puag ncig corrosive nyob rau hauv uas carbon dioxide predominates, Super 13Cr muaj corrosion kuj ntau dua L80-13Cr.Thov kev daws teeb meem rau API 5CT L80 Casing Hnub no.

Txoj kev kho cua sov rau L80 kav

Txhua qib API 5CT L80 (L80-1, L80 9Cr, L80 13Cr) txais yuavQuenched + Tempered (Q&T) kev kho cua sov.Normalizing lossis annealing tsis pub. Tag nrho lub cev quenched thiab tempered kom txwv hardness tsawg dua los yog sib npaug rau 23HRC thiab xyuas kom meej zoo SSC kuj rau qaub kev pab cuam.

1.Overall cua sov: Uniformly heats tag nrho seamless raj rau lub austenitizing kub.

2.Quenching: High-siab dej quenching/spray quenching kom txias ceev kom tau ib tug siab - zog martensitic qauv.

3.Tempering: Tsis tu ncua siab -kub tempering txo hardness, tso tawm sab hauv kev nyuaj siab, thiab txhim kho toughness, nruj me ntsis tswj lub sab sauv txwv hardness kom tsawg dua los yog sib npaug rau 23 HRC.

4.Straightening: Precision kub straightening tom qab kev kho cua sov kom ntseeg tau tias ncaj raws li API 5CT qauv.

5.Mechanical khoom kuaj: Tensile, cuam tshuam, thiab hardness xeem yog ua nyob rau hauv txhua batch kom ntseeg tau ib tug yield zog ntawm 552-655 MPa.

L80 casing yeeb nkab txuas hom

API 5CT L80 casing kev twb kev txuas yog ib qho tseem ceeb tshaj plaws interface specifications ntawm API 5CT casing, uas ncaj qha txiav txim siab sealing kev ua tau zoo, siab bearing muaj peev xwm thiab siv tau zoo tej yam kev mob.API 5CT L80 casing yeeb nkab kev twb kev txuas hom muaj xws li:

STC (Short Round Xov):feem ntau yog siv rau sealing. Feem ntau yog siv rau hauv qhov dej ntiav, tsawg- daim ntawv thov siab, thiab qhov chaw ua haujlwm. Yooj yim rau nruab thiab disassemble, tus nqi qis.

LTC (Long Round Xov):superior sealing thiab tensile lub zog piv rau STC.Suitable rau nruab nrab- qhov tob tob thiab cov pa roj thiab roj qhov dej.L80 General- hom phiaj tseem ceeb xov hom.

BTC (Tebchaws)Siab load-cov kabmob muaj peev xwm, tiv taus compression thiab siab tensile zog; zoo sealing kev ua tau zoo, tsis yooj yim rau plam; L80 yog thawj qhov kev xaiv rau qhov dej acidic thiab qhov tob tob, thiab yog siv rau hauv qhov loj tshaj plaws.

XC (Extreme Line):Tsis xav tau kev sib txuas sab nraud; Kev sib txuas ncaj nraim hauv thiab sab nraud ntawm cov yeeb nkab kawg.Small txheej txoj kab uas hla, txuag qhov chaw zoo.Suitable rau compact wellbore lug, sib sib zog nqus qhov dej, thiab tshwj xeeb kev ua hauj lwm tej yam kev mob.

Peb kuj muabKev sib txuas tshwj xeeb tshwj xeebthiabPlain Endrau vuam thiab kev cai fabrication.BTC yog hom nrov tshaj plaws rau cov qhov dej sib sib zog nqus qaub.

L80 tubing yeeb nkab txuas hom

NUE (Non-Upset Tubing):Cov yeeb nkab kawg: Tsis muaj thickening, ncaj qha machined tapered thread.Round xov, taper 1:16.Tsawg tus nqi, me me txheej kab; Lub zog tensile qis me ntsis.Tseem siv hauv cov qhov dej ntiav ntiav, nruab nrab- qhov dej tob, cov chaw ua haujlwm zoo ib yam.

EUE (Sab nraud chim siab Tubing):Xaus kev ntxhov siab (thickening) ua raws li threading.Tib yam li NU, round thread 1:16.Higher tensile thiab compressive zog, zoo sealing; loj dua coupling sab nraud txoj kab uas hla.Feem ntau siv nyob rau hauv nruab nrab- qhov tob tob, siab- qhov dej siab, thiab qhov dej uas yuav tsum tau muaj zog dua.

IJ (Integral Joint):Ib kawg muaj cov xov sab nraud (PIN), thiab lwm qhov kawg muaj xov sab hauv (BOX). Lawv tuaj yeem txuas ncaj qha ua ke yam tsis muaj kev sib txuas. Cov qauv tsim no muaj qhov me me sab nraud, qhov loj dua annular clearance, thiab tsawg cov ntsiab lus to. Feem ntau siv nyob rau hauv me me - qhov dej bore, kab rov tav qhov dej, thiab siab - qhov dej qaug zog / corrosion.
