Cov ntawv thov siv
Cov hlau yog dav siv hauv cov haujlwm xws lipetroleum, chemical processing, thiab hluav taws xob tsim. Cov cuab yeej tshwj xeeb muaj xws li:
Cov nkoj siab:Reactors, separators, thiab lub tank kheej kheej.
Boilers:Boiler nruas thiab siab - lub thawv ntim ntim.
Cia:Liquefied gas tanks thiab nuclear reactor nkoj.
Kev xa khoom & Kev kho mob
xwm txheej:Feem ntau xa hauvNormalized (N)los yogKub Rolledtej yam kev mob.
Kev kuaj:End-cov neeg siv feem ntau xav tau kev pov thawj ntxiv xws liKev kuaj ultrasonic (UT)thiabSimulated Post-Welded Heat Treatment (SPWHT).
Qib sib npaug
SPV450 yog kwv yees sib npaug rau ob pebASTM A533 Cov Lus Qhia Tshwj XeebCov chav kawm, suav nrog ASTM A533 Hom A, B, thiab C (Class 1).
txheej txheem yam ntxwv
1. Kev kho cua sov ua kom zoo
Txhawm rau ua tiav nws cov txiaj ntsig siab zog (min{0}} MPa), SPV450 feem ntau yog xa mus rau hauv lub xeev Normalized (N) lossis Quenched thiab Tempered (Q + T). Cov txheej txheem no ua kom zoo dua cov nplej loj, txhim kho qhov sib npaug ntawm qhov toughness thiab lub zog thaum ua kom muaj kev sib luag ntawm cov phaj.
2. Txhim kho Weldability
Lub ntsiab lus txhais yog nws txoj kev txhim kho weldability, ua tiav los ntawm kev tswj cov pa roj carbon sib npaug (Ceq). Qhov no txo qhov kev pheej hmoo ntawm qhov txias txias thiab tso cai rau Simulated Post- Weld Heat Treatment (SPWHT), kom ntseeg tau tias cov pob qij txha welded tuav txhua yam kev ntseeg zoo ib yam li cov hlau puag.
3. Precision Rolling thiab Shaping
Kev tsim khoom niaj hnub no feem ntau siv Thermomechanical Controlled Processing (TMCP) lossis cov txheej txheem kub siab tshaj -rolling. Cov no ua kom muaj qhov tseeb qhov tseeb (qhov tsawg kawg nkaus thickness fluctuation) thiab zoo heev flatness, uas yog ib qho tseem ceeb rau kev tsim loj - nplai reactor Cheebtsam los yog spherical tso tsheb hlau luam.
4. Kev soj ntsuam nruj nruj
Cov txheej txheem cuam tshuam nrog kev sim tsis zoo -kev puas tsuaj, feem ntau yog Ultrasonic Testing (UT), txhawm rau txheeb xyuas qhov tsis xws luag. Rau cov ntawv thov tshwj xeeb, nws tseem tuaj yeem raug kuaj HIC (Hydrogen-Induced Cracking) thiab SSC (Sulfide Stress Corrosion) kev kuaj ntsuas.
Tag nrho cov specification thiab cov ntsiab lus muaj nyob rau ntawm kev thov. Cov ntaub ntawv saum toj no yog muab rau kev taw qhia nkaus xwb. Rau kev tsim tshwj xeeb thov hu rau peb cov neeg ua haujlwm muag khoom.
Dab tsi yog cov tshuaj tseem ceeb ntawm SPV450?
Cov tshuaj lom neeg tseem ceeb ntawm SPV450 suav nrog carbon (C), silicon (Si), manganese (Mn), phosphorus (P), sulfur (S), thiab lwm yam. Kev tswj nruj ntawm cov ntsiab lus no ua kom nws cov khoom ruaj khov thiab kev ua haujlwm zoo.
Dab tsi yog qhov tsawg kawg nkaus tawm lub zog ntawm SPV450?
