ASTM A252 Qib 2 Qib 3 Piling Piping yog dab tsi?
ASTM A252 Qib 2 Qib 3 Piling yeeb nkab yog ib qho kev lag luam kauv seam steel yeeb nkab dav siv hauv kev tsim kho hauv pawg rau kev sib sib zog nqus- dej tawm ntug dej hiav txwv, txuas hniav, txoj kev, thiab siab - nce vaj tse nyob rau hauv ntug dej hiav txwv, dej, thiab pas dej. Nws tuaj yeem ncav cuag qhov siab tshaj plaws ntawm txoj kab uas hla ntawm 3,620 hli, feem ntau yog ua los ntawm Q235 thiab Q345 cov ntaub ntawv, nrog rau kev kho kom haum. Nws txoj kab uas hla sab nraud yog 219-3,620 hli, nrog qhov ntev feem ntau ntawm 8-12 meters. Nws yog tsim los ntawm flattening, ntug trimming, thiab tsim steel coil daim hlau ua raws li los ntawm ob -sided submerged arc vuam (SAW) txheej txheem. Cov welds tau dhau los ua ntau yam kev soj ntsuam nrog rau kev kuaj ultrasonic, X-ray rov kuaj xyuas, thiab kuaj hydrostatic.
ASTM A252 Qib 2 Qib 3 Piling Yeeb Nkab Txheej Txheem
ASTM A252 Qib 2 Qib 3 Kauv steel yeeb nkab yog tsim los ntawm txias- ua steel coil rau hauv ib lub voj voog thiab vuam nws siv tsis siv neeg ob - hlau ob npaug -sided submerged arc vuam (SAW).
(1) Cov khoom nyoos(steel coil, welding hlau, thiab flux) raug kuaj xyuas lub cev thiab tshuaj ua ntej siv.
(2) Xaus - mus rau - xaus coil welding yog ua los ntawm ib zaug lossis ob zaug -hlau SAW, nrog rau SAW ntxiv rau kev kho tom qab coiling rau hauv cov yeeb nkab.
(3) Ua ntej-kev kho mob: Cov kauj ruam dhau theem, ntug trimming, npaj, ntxuav nto, thiab ua ntej- khoov ua ntej sib sau.
(4) Kev tswj siab: Ib qho hluav taws xob ntsuas ntsuas kom ruaj khov coil noj los ntawm kev tswj hwm hydraulic siab ntawm ob sab ntawm lub conveyor.
(5) Txoj kev tsim: Sab nrauv lossis sab hauv cov menyuam sib sau yog siv.
(6) Weld gap tswj: Ib qho khoom siv tshwj xeeb ua kom muaj qhov sib txawv ntawm qhov sib txawv, nruj me ntsis tswj cov yeeb nkab txoj kab uas hla, misalignment, thiab weld clearance.
(7) Vuam: Ob sab hauv thiab sab nraud welds siv Lincoln hluav taws xob welders (ib zaug lossis ob npaug -xov hlau SAW) rau qhov ntsuas qhov sib xws.
(8) Hauv - kab kuaj ultrasonic: Txhua qhov weld undergoes nruam tsis siv neeg kuaj ultrasonic rau 100% kev pab them nqi. Cov teeb meem ua rau lub tswb nrov thiab cim, tso cai rau kev hloov kho tam sim ntawd.
(9) Txiav: Cov kav dej raug txiav rau hauv ib tus neeg ntev uas siv cov pa plasma txiav.
(10) Thawj -kev tshuaj xyuas: Thawj peb cov kav dej hauv ib pawg tau kuaj xyuas nruj ntawm cov khoom siv vuam vuam, tshuaj lom neeg muaj pes tsawg leeg, fusion zoo, nto tiav, thiab NDT ua ntej tag nrho cov khoom.
(11) Kev kuaj xyuas tsis raug rov-: cim qhov chaw weld nrog ultrasonic indications undergo phau ntawv ultrasonic thiab X-ray re- kuaj. Kev lees paub qhov tsis xws luag raug kho thiab rov- tshuaj xyuas kom txog thaum pom tseeb.
(12) X-kev tshuaj ntsuam kab hluav taws xob: Tag nrho cov coil taub qab welds thiab T-cov pob qij txha sib txuas txuas txuas txuas tau raug tshuaj xyuas ntawm X-ray TV lossis zaj duab xis.
(13) Kev ntsuam xyuas hydrostatic: Txhua cov yeeb nkab tau dhau los ntawm radial-Kev ntsuas qhov siab nrog cov ntsuas nruj tswj hwm los ntawm lub khoos phis tawj thiab kaw cia.
(14) Xaus machining: Cov yeeb nkab kawg yog cov txheej txheem txheej txheem los xyuas kom meej qhov perpendicularity, bevel kaum sab xis, thiab blunt ntug qhov ntev.
