KHOOM
Tianjin Brisk Steeltsom rau cov khoom tsim thiab muab cov seem hollow thiab steel yeeb nkab
-
LSAW Manufacturing Process:Longitudinally Submerged Arc Vuam siv ib leeg, siab - zoo steel daim hlau tsim mus rau hauv lub tog raj kheej. Qhov ncaj seam yog welded sab hauv thiab sab nraud siv automated multi-wire submerged arc technology. Vim tias cov kab vuam yog ncaj thiab tsis sib xws, nws dhau qhov kev ntxhov siab tsawg kawg nkaus thiab tso cai rau ultra-tsis meej tsis- kuaj kev puas tsuaj (NDT).

FAQ
Q: Thaum twg qhov project engineering yuav tsum tau qhia S275J0H es tsis txhob muaj ntau dua S355J2H qib raws li EN 10219?
A: Qhov kev xaiv los ntawm kev xam cov qauv load thiab kev txhim kho pob nyiaj siv.S355J2Hmuab lub zog tawm los ntau dua (355 MPa) thiab sub-zero toughness, ua rau nws tsim nyog rau siab -load kab lossis arctic ib puag ncig. Txawm li cas los xij, rau feem pua ntawm cov qauv kev tsim vaj tsev siv hluav taws xob ntau- xws li qis- cov kab hauv tsev nce siab, kos npe txhawb nqa, dej cofferdams, thiab cov qauv kev tsim vaj tsev trusses- cov kev cai thauj khoom tsis xav tau 355 MPa. Kev qhiaS275J0Hmuab cov qauv kev nyab xeeb tiag tiag uas xav tau thaum muab cov nqi txuag nyiaj ntau ntawm tag nrho cov hlau tonnage.
Q: Dab tsi yog qhov txiaj ntsig ntawm "Straight Longitudinal Seam (LSAW)" dhau ntawm "Spiral Seam (SSAW)" rau cov khoom siv thauj khoom-cov kabmob?
A: Rau kev siv cov qauv uas cov kav dej ua raws li qhov hnyav -cov kabmob kab lossis pawg hauv paus,LSAWyog nyiam heev. LSAW cov kav dej yog tsim los ntawm ib tus neeg cov paib tiaj tus thiab tau txais kev kho mob hnyav heev - txheej txheem nthuav dav uas ua kom muaj txiaj ntsig zoo dua geometric roundness thiab qis dua qhov kev ntxhov siab piv rau cov kav dej kauv. Tsis tas li ntawd, txoj hlua ncaj nraim yog yooj yim dua los soj ntsuam nrog automated Ultrasonic thiab X-ray systems, muab cov qauv engineers nrog 100% kev soj ntsuam kev nyab xeeb ua raws.
Q: Koj lub zeb ua li cas kom ntseeg tau tias qhov vuam seam profile tsis cuam tshuam nrog cov khoom siv sab nraud lossis cov yeeb nkab clamps?
A: Thaum lub sij hawm ob -sided submerged arc vuam, ib qho kev txuas sab nraud thiab sab hauv vuam (cov hlaws) yog tsim los. Txhawm rau kom paub meej qhov profile du, peb lub Hoobkas dhau cov kav dej los ntawm kev siv tshuab inline milling cutters siab heev. Peb nruj me ntsis tswj lub sab nraud weld hlaws qhov siab kom nyob twj ywm hauv qab tus qauv pub dawb (feem ntau ua kom lub zog hauv qab 1.5mm - 2.0mm). Qhov qis-cov ntaub ntawv tiav no tso cai rau lub tes tsho sib txuas, hnyav- lub luag haujlwm yeeb nkab clamps, thiab sab nraud tiv thaiv-corrosion qhwv txheej rau lub rooj zaum zoo kawg nkaus yam tsis muaj qhov sib txawv ntawm huab cua.
Q: Dab tsi tsis yog -kev kuaj kev puas tsuaj (NDT) matrix yog tus qauv rau EN 10219 tus qauv xa khoom?
A: Kev lees paub zoo yog koom ua ke rau txhua theem ntawm peb cov kab ntau lawm. Tam sim ntawd tom qab automated vuam thiab kuaj hydrostatic, 100% ntawm longitudinal weld seam undergoes nruam automatedKev kuaj ultrasonic (UT)txhawm rau txheeb xyuas qhov tsis muaj - ntawm - fusion lossis micro-voids. Txhawm rau kom ntseeg tau tias qhov chaw tseem ceeb- thaj chaw sib koom ua ke tsis muaj qhov tsis zoo, cov yeeb nkab kawg raug txheeb xyuas sivSiab -Kev Ntsuas Radiographic (RT/X-ray)thiab Magnetic Particle Inspection (MPI) raws cov npoo beveled ua ntej ntim seaworthy zaum kawg.
