Daim ntawv thov qauv thiab tsim nyog Scenarios
High- zaus welded steel kav thiab submerged arc welded ncaj seam steel kav nrog ib txoj kab uas hla ntawm 550mm feem ntau yog siv nyob rau hauv nruab nrab - thiab siab - siab roj av kis kab mob, twj tso kua mis chaw nres tsheb manifold kev twb kev txuas, thiab tiv thaiv seem ntawm faus casings. Cov qauv pom zoo rau qis- mus rau siab- cov ntawv thov kev xa xov siab feem ntau suav nrog GB/T 9711 PSL1/PSL2 nyob rau hauv cov kav dej siab, API 5L rau cov kav dej, thiab GB/T 3091-2018 rau qis- cov kua xa tawm. Nyob rau hauv suburban thiab roj/gas sib sau ua ke tej yaam num, kev ruaj ntseg ntawm circumferential weld hlaws tsim, lub hauv paus cov ntaub ntawv toughness, thiab ntev corrosion kuj yog cov cim tseem ceeb nyob rau hauv qhov project bidding thiab xa khoom txais.
Cov txheej txheem tseem ceeb ntws thiab cov ntsiab lus tswj tau zoo
Cov txheej txheem tseem ceeb ntawm qhov siab - zaus welded yeeb nkab ntau lawm kab muaj xws li: strip uncoiling → yob txoj kev → siab - zaus induction cua sov vuam → online weld seam extrusion thiab deburring → nruab nrab - zaus los yog induction annealing → 3 stabilization → stabilization → 3 stabilization Hydrostatic testing → kawg ua → ntim thiab labeling. Cov kev tshuaj xyuas tseem ceeb ntxiv rau cov phiaj xwm faus cov kav dej muaj xws li: tag nrho- kev kuaj xyuas ultrasonic (UT) ntawm thaj chaw weld, kev tshuaj ntsuam online eddy tam sim no, thiab X-ray chaw kuaj xyuas. Txhua batch tau kuaj xyuas hydrostatic siab stabilization ntawm 1.5 npaug ntawm kev tsim siab. Welds yuav tsum tsis muaj qhov tsis muaj fusion, tawg, lossis laminar tsis xws luag. Rau daim ntawv cog lus lees txais cov ntaub ntawv, vuam parameter nkhaus, NDT cov ntawv ceeb toom, tiv thaiv- kev tshuaj xyuas cov txheej txheem corrosion, thiab kev ruaj ntseg nkhaus yuav tsum yog ib qho - rau - ib qho sib tw nrog cov lej traceable.
Carbon Steel Qib Sib Piv thiab Cov Khoom Xaiv Logic
Q235B feem ntau yog siv rau huab cua thiab qis - cov roj av sib sau ua ke; Q355B yog qhov tsim nyog rau nruab nrab- rau- siab- cov xwm txheej sib kis uas xav tau lub zog ntau dua thiab cov khoom yuav tsum tau muaj; L245 series cov qib qhia txog kev sib txuas thiab kev sib tsoo toughness nyob rau hauv cov txheej txheem txheej txheem, thaum txheej kev ntseeg tau zoo sib npaug rau qhov ntev - kis tau tus mob hauv cov av ntub dej faus. Qhov sib txawv tseem ceeb ntawm Q235B, Q235C, Q355B, thiab Q355C nyob hauv qis- qhov kub thiab txias cuam tshuam, lub zog tawm los, thiab tswj cov ntsiab lus ntawm cov pa roj carbon ntau. Rau qis-kub roj thiab cov roj faus cov kav dej, C- qib lossis J2H- qib steels uas muaj kev cuam tshuam ruaj khov dua yog qhov zoo dua, txawm tias qhov txias txias yuav tsum tau txo qis hauv cov txheej txheem vuam tshwj xeeb. Peb cov khoom siv raw yog tsim los ntawm cov khoom muaj npe kub -rolled coil mills nrog zoo ib yam. Cov khoom siv tshuaj lom neeg muaj pes tsawg leeg thiab Ceq carbon sib npaug yog tswj tsis pub dhau 0.30-0.43 ntau yam, ua kom lub qhov rais dav weldability thiab txo qhov kev pheej hmoo ntawm pob tw vuam.
Delivery Management thiab Project Case Support System
Ntau cov phiaj xwm choj yuav tsum muaj cov kav hlau, tab sis qhov lawv xav tau tiag tiag yog "muaj peev xwm ua tiav." Peb lub peev xwm xa khoom sib xyaw ua ke muaj peev xwm ua tau zoo: Tshaj li cov kav dej hauv cov kav dej, peb muab kev ua tiav zoo li cov yeeb nkab kawg chamfering, pawg khau installation, welded reinforcement rings, flanged pawg cap interfaces, txhim khu kev tiv thaiv kev tiv thaiv, thiab lwm yam cim / positioning kab. Rau cov kev qhia tshwj xeeb xws li DN320 siv rau hauv cov choj hauv paus- qhov twg lub zog yog qhov tseem ceeb yam tsis muaj ntau dhau - qhov tseeb hauv kev ua haujlwm siab dhau los ua qhov tseem ceeb. Peb pab neeg ua haujlwm raws li qhov chaw tsim kho qhov chaw txhawb nqa: Tshaj li muab cov kav dej steel, peb muab cov lus pom zoo piling, txheej txheej, txiav - rau -ntev cov phiaj xwm, kev sib koom ua ke ntawm lub sijhawm xa khoom, thiab cov qauv tshuaj ntsuam xyuas cov qauv- pab lub xaib kom tsis txhob muaj kev cuam tshuam. Kev xa khoom yog tiag tiag, cov xwm txheej muaj tiag, thiab muaj peev xwm muaj peev xwm tiag tiag-Tshaj qhov khoom xa tuaj, peb xa kev thaj yeeb nyab xeeb.
