N80 EUE Roj Tubing
N80 cevyog lub teb chaws roj tubular zoo (OCTG) ua raws li covAPI Spec 5CTtxheem.
"N80":Hais txog qib yield zog, txhais tau tias qhov tsawg kawg nkaus lub zog yog 80,000 psi (552 MPa).
Lus Cim: Muaj ob hom:N80-1(feem ntau normalized) thiabN80-Q(Quenched thiab Tempered rau siab dua uniformity).
"EUE" (External Upset End):Hais txog hom kev sib txuas ntxiv. Phab ntsa thickness ntawm qhov kawg ntawm cov yeeb nkab yog nce los ntawm kub - txheej txheem forging ua ntej threading. Qhov no ua kom ntseeg tau tias qhov kev sib txuas muaj zog dua li cov yeeb nkab lub cev, tiv thaiv kev sib koom ua ke tsis ua haujlwm hauv cov khoom hnyav hauv qhov dej tob.

Nta ntawm N80 EUE Roj Tubing
Siab Load Capacity:N80 yog kwv yees li 45% muaj zog dua qib J55 / K55, ua rau nws haum rau cov qhov dej tob thiab siab dua - ib puag ncig siab.
Lub zog sib koom tes (EUE):Sab Nraud Upset tsim nce tus ntoo khaub lig- ntu ntu ntawm threaded kawg. Qhov no ua rau muaj txiaj ntsig zoo ntawm kev ua haujlwm shear thiab sealing kev ntseeg siab, tiv thaiv "sib koom rub- tawm" nyob rau hauv siab nruj.
Versatility:N80 yog qib "qab zib" hauv kev lag luam- nws muaj lub zog siab yam tsis muaj nkig lossis kim li qib siab dua li P110.
Cov kev xeem nruj:Txhua qhov sib koom ntawm N80 yuav tsum raug:
Hydrostatic Test:Txhawm rau kom tsis txhob muaj dej los yog tawg ntawm qhov siab.
Tsis yog -Kev Ntsuas Kev Puas Tsuaj (NDT):Xws li Ultrasonic lossis Eddy Tam sim no kuaj xyuas kom cov yeeb nkab tsis muaj kab nrib pleb.
Drift Test (Drifting):Xyuas kom tus ID yog qhov tseeb rau cov cuab yeej downhole kom dhau mus.

FAQ
Q1: Dab tsi yog qhov txawv ntawm N80-1 thiab N80-Q?
A:Qhov no yog qhov sib txawv tseem ceeb tshaj plaws rau N80 tubing.
N80-1:Feem ntau xa hauv aLi qubmob. Nws yog tus nqi ntau dua - zoo thiab haum rau cov qauv zoo ib puag ncig.
N80-Q:Xa hauv aQuenched thiab Tempered (Q & T)mob. Nws muaj superior zog uniformity thiab zoo qaug zog tiv thaiv, ua rau nws ntau txhim khu kev qha rau xav tau zoo tej yam kev mob.
Q2: Vim li cas "EUE" (External Upset End) nyiam tshaj "NUE" (Tsis yog-Upset End)?
A:EUE yog tus qauv kev lag luam rau feem ntau cov qhov dej. Cov txheej txheem "Upset" nce phab ntsa thickness ntawm qhov kawg ntawm cov yeeb nkab ua ntej threading. Qhov no xyuas kom meej tias covkev sib koom ua ke muaj zog yog siab dua cov yeeb nkab lub cev lub zog, tiv thaiv "sib koom rub- tawm" lossis tsis ua haujlwm nyob rau hauv lub siab nruj thiab siab pom hauv qhov dej tob.
Q3: Puas yog N80 EUE tubing haum rau Sour Service (H2S ib puag ncig)?
A: Tsis muaj.N80 yog ib qho nruab nrab - mus rau - siab zog steel uas raug rauSulfide Stress Cracking (SSC)hauv H2S ib puag ncig. Rau kev pabcuam qaub, peb pom zoo kom sivL80-1, C90, los yogT95qib, uas yog tsim tshwj xeeb los tiv thaiv hydrogen embrittlement.
