Txoj Cai Kho Mob thiab Vuam Cov Ntsiab Lus

Qhov kawg kev ua tau zoo ntawm API 5L X80 nyob ntawm TMCP tswj dov thiab tswj cov txheej txheem txias:

1. Tswj Rolling and Controlled Cooling (TMCP, siv kom tau txais ib qho zoo -grained microstructure thiab pom zoo txhua yam khoom):

Thaum tshav kub kub mus rau 1100-1200℃rau ntxhib dov, ces ua tswj dov nrog txo loj nyob rau hauv lub 850-950℃tiav kub ntau yam (dov nyob rau hauv lub non-recrystallization cheeb tsam), ua raws li los ntawm kev tswj kom txias nyob rau hauv 600-800℃. Qhov no ua rau muaj qhov sib xws thiab nplua acicular ferrite + bainite microstructure (grain loj feem ntau ntau dua lossis sib npaug li 10-11), ua kom muaj kev sib npaug ntawm lub zog thiab tawv. Rau cov kav dej qaub, TMCP yog txoj hauv kev nyiam kom tsis txhob muaj nag lossis daus ntawm cov theem teeb meem.

2. Tshaj tawm -weld Kev kho cua sov (yog tias xav tau):

Yog tias yuav tsum tau muaj kev ntxhov siab tom qab cov yeeb nkab nplhaib vuam vuam, tom qab- vuam cua sov kho ntawm 550-650℃rau 1-2 teev tuaj yeem ua tau. Kev kho cua sov tom qab vuam yuav tsum tau them sai sai rau kev tswj cov cua sov thiab cua txias kom tsis txhob cuam tshuam cov microstructure thiab cov khoom ntawm cov khoom siv hauv paus.

Lus ceeb toom tseem ceeb:

Nyob rau hauv cov pa roj thiab roj kis ib puag ncig yam tsis muaj H₂S, kev ntxhov siab kev kho cua sov feem ntau tsis tas yuav tsum tau tom qab vuam.

Rau cov kav dej hauv ib puag ncig acidic (muaj H₂S), kev ua raws cai nruj nrog Cov Ntawv Ntxiv J ntawm API 5L PSL2 yog qhov yuav tsum tau tiv thaiv kom tsis txhob muaj zog ntau dhau (tsawg dua lossis sib npaug li 250 HV) tshwm sim los ntawm kev xa tawm tsis raug -weld heat treatment.

Thaum lub sij hawm vuam, kev tswj xyuas nruj ntawm cov khoom siv hluav taws xob (pom zoo 0.5-2.5 kJ / mm) thiab qhov kub ntawm qhov sib cuam tshuam (feem ntau tsawg dua lossis sib npaug li 100 degree) yuav tsum tau tiv thaiv cov nplej coarsening nyob rau hauv thaj chaw muaj kev kub ntxhov thiab kev nyuaj siab heev.

5. Welding Material Matching:
• PSL1: Nws raug nquahu kom siv E6010 cellulose electrodes rau hauv paus hla vuam, ua raws li E7010/E8010 electrodes rau sau thiab npog dhau.
• PSL2: Nws raug nquahu kom siv qis -hydrogen electrodes E8010/E9010 lossis GMAW khoom / cored vuam hlau

Q: Dab tsi yog qhov corrosion kuj ntawm API 5L X80?

Q: API 5L X80 puas tuaj yeem hloov ASTM A53 lossis X70?

Nws tuaj yeem hloov qee qhov, tshwj xeeb tshaj yog nyob rau hauv daim ntawv thov nrog kev siv siab thiab zoo weldability yuav tsum:
Cov xwm txheej tsim nyog rau kev hloov pauv:
• Ultra-siab- kev thauj mus los ntawm cov kua dej:
Lub zog ntawm X80 (555 MPa) yog qhov siab dua ntawm qib A53 B (240 MPa), X42 (290 MPa), X52 (360 MPa), X60 (415 MPa), thiab X70 (485 MPa). Nyob rau hauv tib txoj kab uas hla sab nraud thiab siab, nws tso cai rau kom txo tau cov phab ntsa thickness, uas ua rau muaj qhov hnyav hnyav.
• Cov kab hauv lub cev tseem ceeb ntawm txoj kab ntev - nrug:
X80 yog cov qib steel ua rau ultra-siab-siab ntev- kis tau tus mob kav, uas muaj lub zog siab thiab tus nqi zoo- ua tau zoo. Nws yog dav siv nyob rau hauv lub teb chaws tej yaam num xws li Tuam Tshoj -Russia East Pipeline.
• Marine engineering structural kav:
Cov yam ntxwv ntawm ultra-siab zog ntawm X80 yog haum rau hnyav-load qauv xws li offshore platforms

Cov xwm txheej uas hloov pauv tsis haum:
• Tsis yog- cov khoom siv siab:
A53/A500 cov hlab ntsha yog tus nqi ntau dua - zoo
• Nruab nrab thiab qis - cov kav dej siab:
X42 lossis X52 txaus, X80 muaj zog ntau dhau
• Ib puag ncig acidic (H₂S):
Nws yog ib qho tsim nyog kom paub meej tias cov kev cai tiv thaiv -acid tau ua tiav. Ib txwm X80 tsis siv tau; X80MS yuav tsum tau xaiv los hloov.Txawm li cas los xij, X80 raug rau qee yam kev txwv thaum ua haujlwm hauv cov kua qaub.
• Vuam kev tsim kho yog txwv:
X80 yog rhiab heev rau vuam cua sov input thiab yuav tsum tau nruj tswj

Cov lus pom zoo xaiv cov khoom:
Rau kev xaiv cov khoom tshwj xeeb, thov muab cov ncauj lus kom ntxaws txog kev ua haujlwm (tsim siab, xa tawm nruab nrab, qhov kub thiab txias, muaj H₂S / CO₂, vuam qhov yuav tsum tau ua, txoj kab uas hla thiab phab ntsa thickness). Peb tuaj yeem pab nrog kev txheeb xyuas kev sib piv thiab kev lag luam los pab koj xaiv qhov zoo tshaj plaws ntawm X80 thiab lwm qib steel.
Rau cov lus hais txog cov kev qhia tshwj xeeb, cov ntaub ntawv xeem cov ntaub ntawv, lossis cov ntawv txheeb xyuas, thov hu rau peb cov kws tsim khoom muag. Peb txhawb customizing qhov ntev, kev xa khoom, thiab kev kho deg (txheej / plating) raws li qhov xav tau, thiab muab tag nrho cov ntaub ntawv pov thawj thoob ntiaj teb (API, ISO, EN, GB, thiab lwm yam).
