Longitudinal Submerged Arc Welded (LSAW) steel kav yog cov pob txha ntawm cov phiaj xwm tseem ceeb thoob ntiaj teb, tshwj xeeb tshaj yog nyob rau hauv siab - roj thiab roj xa mus, thiab loj - daim ntawv thov cov qauv. Kev ncaj ncees thiab kev ntseeg siab ntawm cov kav dej no tsis yog - sib tham, vim tias kev ua tsis tiav tuaj yeem ua rau muaj kev puas tsuaj rau ib puag ncig, kev lag luam, thiab kev nyab xeeb. Yog li ntawd, kev tswj xyuas nruj nruj (QC) thiab qib siab tsis yog -kev kuaj kev puas tsuaj (NDT) tsis yog cov kev cai tswjhwm nkaus xwb tab sis tseem ceeb ntawm LSAW yeeb nkab tsim. Hebei Huayang Steel Pipe Co., Ltd., tus thawj coj hauv kev tsim cov khoom siab tshaj - zoo LSAW kav, tau mob siab rau kev txhawb nqa cov qauv siab tshaj plaws los ntawm kev ua kom zoo, ntau- theem kev pov hwm zoo.
Qhov tseem ceeb ntawm Kev Tswj Xyuas Zoo hauv LSAW Pipe Manufacturing
Qhov xav tau ib puag ncig uas LSAW cov kav dej ua haujlwm yuav tsum tau ua kom tsis muaj kev cuam tshuam rau qhov zoo. Cov kav dej no feem ntau raug kev kub ntxhov, kev tshaj tawm corrosive, qhov kub thiab txias, thiab kev ntxhov siab. Txhua qhov tsis xws luag, txawm tias me me npaum li cas, tuaj yeem nthuav tawm raws sijhawm, cuam tshuam rau cov yeeb nkab ntawm cov qauv kev ncaj ncees thiab ua rau ua tsis tiav ntxov. Kev tswj kom zoo ua kom ntseeg tau tias txhua LSAW yeeb nkab tsim tau raws li lossis tshaj li cov khoom siv kho qhov muag, qhov ntev ntev, thiab cov kev xav tau ntawm kev ncaj ncees.
Ntawm Hebei Huayang Steel Pipe Co., Ltd., peb lub tswv yim tswj kev tswj kom zoo yog kev koom ua ke rau txhua theem ntawm kev tsim khoom, los ntawm cov khoom siv raw khoom mus rau qhov kawg khoom xa tuaj. Qhov kev sib koom ua ke no txo qis kev pheej hmoo, txhim kho cov khoom lag luam, thiab thaum kawg muab peb cov neeg siv khoom ntseeg siab tias lawv cov haujlwm tau tsim nrog cov ntaub ntawv txhim khu kev qha tshaj plaws. Peb qhov kev cog lus txuas ntxiv tshaj qhov ua raws li kev ua raws cai; peb mob siab rau kev txhim kho tas mus li hauv peb cov txheej txheem QC kom cia siab thiab daws cov teeb meem kev lag luam tawm tshiab.
Cov theem tseem ceeb ntawm Kev Tswj Xyuas Zoo hauv LSAW Production
Kev tsim cov kav dej LSAW suav nrog ntau theem tseem ceeb, txhua tus nrog nws tus kheej cov txheej txheem ntawm kev kuaj xyuas zoo kom ntseeg tau tias cov khoom tsis muaj qhov kawg.
Raw Material Inspection
Txoj kev taug mus rau qhov siab - zoo LSAW yeeb nkab pib nrog kev xaiv thiab tshuaj xyuas cov hlau tsis zoo. Incoming materials undergo thorough chemical analysis, mechanical property testing (tensile strength, yield strength, impact toughness), and ultrasonic inspection to detect any internal laminations or defects. Tsuas yog daim hlau uas ua tau raws li peb cov lus qhia nruj heev tau pom zoo rau kev tsim khoom.
Phaj Ntug Kev Npaj thiab Kev Ua Haujlwm
Ua ntej tsim, cov npoo ntawm cov hlau phaj yog precisely milled los xyuas kom meej qhov zoo ntawm weld npaj. Thaum lub sij hawm tsim cov txheej txheem, cov hlau yuav maj mam khoov mus rau hauv ib tug cylindrical zoo. Kev soj ntsuam tas li ntawm cov txheej txheem tsim, suav nrog curvature thiab kev sib dhos, yog qhov tseem ceeb kom ua tiav cov yeeb nkab geometry kom raug thiab txo qis kev ntxhov siab sab hauv.
Vuam txheej txheem tswj
Cov txheej txheem submerged arc vuam (SAW) yog lub plawv ntawm LSAW yeeb nkab raug tsim. Qhov tseem ceeb welding tsis xws li tam sim no, voltage, mus txawv tebchaws ceev, thiab flux muaj pes tsawg leeg yog tsis tu ncua saib thiab tswj. Ob qho tib si sab hauv thiab sab nraud tau ua tiav, thiab kev tshuaj xyuas pom tau ua tom qab txhua qhov dhau los txhawm rau txheeb xyuas qhov tsis zoo ntawm qhov chaw. Kev siv cov cuab yeej siv vuam zoo heev thiab cov neeg ua haujlwm txawj ua kom muaj qhov zoo sib xws.
Mechanical Expansion thiab Sizing
Tom qab vuam, LSAW cov kav dej feem ntau tau siv cov tshuab txuas ntxiv. Cov txheej txheem no tsis tsuas yog qhov loj me me ntawm cov yeeb nkab rau nws qhov kawg qhov ntev tab sis kuj txhim kho nws qhov sib npaug thiab ncaj, thaum tib lub sijhawm txo cov kev ntxhov siab los ntawm vuam. Dimensional checks, nrog rau sab nraud txoj kab uas hla, phab ntsa thickness, thiab ntev, yog ua nruj me ntsis nyob rau theem no.
Advanced Tsis yog -Kev Ntsuam Xyuas Kev Puas Tsuaj (NDT) Cov Txheej Txheem
Tsis yog-Kev kuaj kev puas tsuaj ua lub luag haujlwm tseem ceeb hauv kev txheeb xyuas qhov ncaj ncees sab hauv thiab sab nraud ntawm LSAW kav yam tsis muaj kev puas tsuaj rau cov khoom. Hebei Huayang Steel Yeeb Nkab Co., Ltd. ntiav ib chav suite ntawm advanced NDT txoj kev los xyuas kom meej cov kev puas tsuaj.
Kev kuaj ultrasonic (UT)
UT yog siv los txheeb xyuas qhov tsis zoo ntawm sab hauv, xws li cov kab nrib pleb, laminations, thiab suav nrog, hauv ob qho tib si weld seam thiab lub cev yeeb nkab. Siab - zaus lub suab nthwv dej yog kis los ntawm cov yeeb nkab, thiab txhua qhov kev xav tau qhia tias muaj qhov tsis sib xws. Peb cov tshuab UT automated muab 100% kev pabcuam ntawm cov vuam thiab ib feem tseem ceeb ntawm cov yeeb nkab lub cev.
X-ray duab
X-ray tshuaj ntsuam xyuas muab cov ntaub ntawv pom ntawm cov qauv sab hauv ntawm lub vuam seam, tso cai rau kev tshawb pom qhov tsis xws luag xws li porosity, slag inclusions, thiab tsis muaj fusion. Txoj kev no yog qhov tshwj xeeb tshaj yog rau kev txheeb xyuas qhov tsis txaus ntseeg uas yuav tsis yooj yim pom los ntawm lwm cov tswv yim.
Magnetic Particle Inspection (MPI)
MPI feem ntau yog siv los txheeb xyuas qhov chaw thiab ze ntawm -surface discontinuities nyob rau hauv cov ntaub ntawv ferromagnetic. Ib qho chaw sib nqus yog siv rau hauv cov yeeb nkab, thiab cov khoom sib nqus tau kis mus rau saum npoo. Cov tsis xws luag ua rau cov hlau nplaum sib nqus, nyiam cov khoom thiab ua rau pom qhov tsis zoo. Qhov no feem ntau yog siv rau ntawm weld xaus thiab bevels.
Kev Ntsuas Hydrostatic
Kev ntsuam xyuas hydrostatic yog qhov yuav tsum tau ua zaum kawg rau kev ntsuas siab - uas muaj cov kav dej. Cov yeeb nkab yog ntim nrog dej thiab pressurized mus rau ib theem siab dua nws qhov siab tshaj plaws kev khiav hauj lwm siab. Qhov kev sim no txheeb xyuas cov yeeb nkab lub peev xwm los tiv thaiv lub siab sab hauv thiab lees paub qhov tsis muaj qhov xau, ua kom cov yeeb nkab haum rau kev pabcuam.
Hebei Huayang kev cog lus rau LSAW Quality
Hebei Huayang Steel Yeeb Nkab Co., Ltd. tau cog lus los xa LSAW steel kav uas muaj qhov zoo tshaj plaws thiab kev ntseeg tau. Peb lub xeev- ntawm--Art CNAS-cov ntawv pov thawj kuaj xyuas ua tiav kev tshuaj xyuas lub cev thiab tshuaj lom neeg, ua kom cov khoom ua raws cai. Peb tuav ntau daim ntawv pov thawj thoob ntiaj teb, suav nrog ISO 9001, ISO 14001, ISO 45001, API 5L, thiab API 2B, uas ua pov thawj rau peb ua raws li kev tswj hwm thoob ntiaj teb zoo thiab cov qauv khoom. Peb cov neeg ua haujlwm siab tshaj plaws ntawm cov kws tshaj lij thiab cov cuab yeej ntsuas qib siab kom ntseeg tau tias txhua qhov LSAW yeeb nkab tawm hauv peb qhov chaw yog qhov siab tshaj plaws.
