Hauv cov roj thiab roj tsheb thauj mus los, cov kav dej hauv nroog, loj -tej dej txuag dej, thiab lub zog ua haujlwm, Longitudinal Submerged Arc Welded (LSAW) steel kav tau siv dav hauv cov haujlwm uas yuav tsum muaj kev nyab xeeb siab vim lawv lub siab muaj zog -cov kabmob muaj peev xwm, cov qauv ruaj khov, thiab kev tswj tau zoo. Txawm li cas los xij, ntau tus neeg yuav khoom tseem muaj qhov sib txawv hauv kev nkag siab "yuav ua li cas xaiv, nrhiav dab tsi, thiab yuav txiav txim siab li cas" thaum nws los txog rau LSAW steel kav. Raws li kev siv engineering, kab lus no tau txheeb xyuas cov ntsiab lus tseem ceeb ntawm kev xaiv LSAW steel kav los pab cov neeg yuav khoom txiav txim siab ntau dua.
1. Qhia meej txog EngineeringDaim ntawv thovScenarios thiab tsim cov kev xav tau
Ua ntej yuav LSAW steel kav, lub luag haujlwm tseem ceeb tsis yog los sib piv cov nqi tab sis kom paub meej cov kev pabcuam ntawm cov kav dej. Cov haujlwm sib txawv muaj qhov sib txawv tseem ceeb hauv cov kev xav tau rau cov kav dej steel, feem ntau suav nrog:
- Hom kev thauj nruab nrab (cov roj av, roj av, dej, tshuaj lom neeg, thiab lwm yam)
- Tsim kev ntsuas siab
- Kev khiav hauj lwm ib puag ncig (burried underground, saum av, underwater, marine ib puag ncig)
- Txawm hais tias cov yeeb nkab yog lub kav dej loj lossis lub qhov tseem ceeb
Piv txwv li, ntev -qhov deb siab- cov roj thiab cov kav dej siab muaj qhov yuav tsum tau ua ntau dua rau cov yeeb nkab steel lub zog, tawv, thiab vuam seam kev ntseeg tau ntau dua li cov kav dej hauv nroog. Tsuas yog tom qab qhia meej txog kev xav tau ntawm engineering tuaj yeem muaj lub hauv paus rau cov khoom siv tom ntej, kev qhia tshwj xeeb, thiab kev tshuaj ntsuam xyuas.
2. Xaivqhov tsim nyogCov Qauv Ua Haujlwm
Cov qauv kev ua haujlwm zoo rau LSAW steel kav suav nrog API 5L, GB / T 9711, ASTM, EN, GOST, thiab lwm yam. Cov qauv sib txawv sib txawv hauv cov hauv qab no:
- Tswj ntau yam tshuaj muaj pes tsawg leeg
- Mechanical Property Requirements
- Impact test tej yam kev mob
- Tsis yog-kev ntsuas kev puas tsuaj
Thaum lub sij hawm yuav khoom, tus qauv yuav tsum nruj me ntsis xaiv raws li cov ntaub ntawv tsim los yog tus tswv yuav tsum tau kom tsis txhob "tus qauv mismatch." Nws yuav tsum raug sau tseg tias qee qhov haujlwm muaj cov kev cai meej ntawm cov qauv qauv, thiab "tib yam- qauv qauv" tsis tuaj yeem hloov pauv yooj yim.
3. Hlau Phaj Raw Khoomyog Basis rauZoo
LSAW steel kav siv nruab nrab - tuab steel daim hlau raws li cov khoom siv raw, thiab qhov zoo ntawm cov hlau phaj ncaj qha txiav txim siab qhov kev ua tau zoo ntawm cov kav hlau ua tiav. Cov ntsiab lus tseem ceeb rau kev tsom mus rau thaum lub sijhawm yuav khoom muaj xws li:
- Seb cov hlau phaj qhov chaw ruaj khov thiab traceable
- Seb nws yog tshwj xeeb pipeline steel phaj
- Txawm hais tias lub phaj hlau tau dhau los ua haujlwm zoo lossis tswj kev dov thiab kev kho cua txias
- Muaj daim ntawv pov thawj steel phaj tiav
Siab - zoo LSAW steel kav feem ntau ua nruj soj ntsuam ntawm cov hlau phaj los ntawm qhov chaw es tsis yog nrhiav cov nqi qis.
4. Ua tib zoo saib cov txheej txheem tsim thiab vuam theem
Cov txheej txheem sib sau ua ke ntawm LSAW steel kav muaj xws li JCOE, UOE, thiab lwm yam. Cov txheej txheem sib txawv muaj qhov sib txawv ntawm kev tsim qhov tseeb thiab kev tswj kev ntxhov siab. Mature forming txheej txheem pab xyuas kom meej:
- Stable yeeb nkab txoj kab uas hla thiab ovality
- Uniform yeeb nkab phab ntsa thickness
- Ua raws li kev sib txuas
Nyob rau hauv cov nqe lus ntawm welding, tsom mus rau seb lub submerged arc vuam txheej txheem ntawm welding sab hauv thiab sab nraud welding yog saws thiab seb cov txheej txheem vuam muaj qhov ruaj khov parameter tswj kev muaj peev xwm. Weld formation zoo yog ncaj qha ntsig txog lub siab -kev ua tau zoo thiab kev pabcuam lub neej ntawm cov yeeb nkab steel.
5. Kev tshuaj xyuas Weld thiab Kev Tshuaj Xyuas Txhuas Yeeb NkabYuav tsum tsis txhob saib
Weld seam yog qhov tseem ceeb tshaj plaws ntawm cov kav hlau welded. Tsim nyog LSAW steel kav yuav tsum muaj kev tshuaj xyuas tiav, suav nrog:
- Weld ultrasonic kuaj
- Weld radiographic kuaj
- Lub cev ultrasonic kuaj
- Kev ntsuam xyuas hydrostatic
Thaum lub sij hawm kev yuav khoom, tsis tsuas yog them sai sai rau "txawm qhov kev tshuaj ntsuam xyuas" tab sis tseem tsom mus rau seb qhov kev soj ntsuam piv thiab cov ntaub ntawv soj ntsuam puas tiav. Rau cov haujlwm tseem ceeb hauv engineering, nws raug nquahu kom ua qhov tseem ceeb rau cov tuam txhab lag luam nrog cov txheej txheem tshuaj xyuas thiab cov ntaub ntawv taug qab.
6. Dimensional raug thiabQhov tshwm simZoo YogSib npaugTseem ceeb
Txawm hais tias qhov sib txawv ntawm qhov sib txawv yuav tsis cuam tshuam rau kev pabcuam kev nyab xeeb tam sim ntawd, lawv yuav ua rau muaj ntau yam teeb meem hauv kev tsim kho tom qab. Thaum yuav LSAW steel kav, tsom rau:
- Sab nraud txoj kab uas hla thiab phab ntsa thickness tolerances
- Cov yeeb nkab kawg bevel thiab kawg lub ntsej muag perpendicularity
- Cov yeeb nkab ncaj
- Muaj qhov pom tseeb indentations, tawg, lossis folds ntawm qhov chaw
Cov ntsiab lus no feem ntau qhia txog qib tseeb ntawm lub Hoobkas hauv kev tswj hwm kev tsim khoom thiab kev tswj kom zoo.
7. Kev txhawb nqa peev xwm thiab kev xa khoom yog qhov tseem ceebKev txiav txim siab
Rau engineering tej yaam num, steel kav tsis yog tsuas yog "cov khoom" tab sis kuj yog ib tug systematic muab kev pab cuam. Mature LSAW steel yeeb nkab manufacturers feem ntau muaj:
- Muaj peev xwm tsim tau ruaj khov rau loj - txoj kab uas hla thiab ntau - cov khoom tshwj xeeb
- Muaj kev paub hauv batch xa khoom thiab kev sib koom tes ua haujlwm
- Txhawb kev pabcuam xws li tiv thaiv- corrosion thiab txheej
- Clear project execution thiab kev sib txuas lus mechanisms
Cov yam tseem ceeb no tseem ceeb tshwj xeeb thaum lub voj voog txoj haujlwm nruj thiab cov kev xav tau siab.
8. Kev xavly Ntsuam xyuasNqe sib txawv
Tus nqi sib txawv ntawm LSAW steel kav feem ntau yog los ntawm cov hauv qab no:
- Qhov sib txawv ntawm qib raw khoom
- Variations nyob rau hauv soj ntsuam cov qauv thiab proportions
- Qhov sib txawv ntawm cov txheej txheem tswj theem
- Qhov sib txawv ntawm kev tswj hwm kev nqis peev zoo
Thaum lub sijhawm yuav khoom, tsis txhob siv tus nqi qis raws li qhov kev txiav txim siab ib leeg; Hloov chaw, ntsuas cov khoom ua tau zoo, kev pheej hmoo ntawm kev nyab xeeb, thiab cov nqi siv sijhawm ntev -.
Xaus
Xaiv LSAW steel kav yog qhov tseem ceeb ntawm kev txiav txim siab ntawm kev nyab xeeb, kev ntseeg siab, thiab kev tsim muaj peev xwm. Pib los ntawm engineering xav tau thiab systematically txiav txim siab cov qauv, raw khoom, txheej txheem, thiab kev soj ntsuam, peb muaj peev xwm xaiv cov khoom tiag tiag haum rau peb tes num.
Raws li cov kws tshaj lij kev lag luam nrog ntau tshaj 20 xyoo ntawm kev paub hauv LSAW steel yeeb nkab raug tsim, Huayang Steel Yeeb Nkab tau tsim cov khoom lag luam nplua nuj thiab kev tsim khoom siv hluav taws xob hauv thaj tsam loj - txoj kab uas hla LSAW steel kav. Nws cov khoom siv npog ntau yam qauv thoob ntiaj teb thiab tau siv dav hauv cov roj thiab roj, lub zog, thiab cov phiaj xwm kev tsim kho, muaj peev xwm muab cov neeg siv khoom ruaj khov thiab txhim khu kev qha cov kav dej.
