Cov txheej txheem ntau lawm ntawm kauv steel yeeb nkab

Lub kauv steel yeeb nkab yog tsim los ntawm dov qis-carbon structural steel los yog low-alloy structural steel sawb rau hauv cov yeeb nkab, raws li ib lub kaum sab xis ntawm kauv kab (hu ua lub kaum sab xis), thiab ces welding cov yeeb nkab seams.
Nws tuaj yeem siv los tsim cov kab loj loj steel yeeb nkab nrog nqaim sawb steel.
Cov lus qhia ntawm kauv steel yeeb nkab yog qhia los ntawm sab nraud * phab ntsa thickness.
Cov yeeb nkab welded yuav tsum raug kuaj los ntawm kev ntsuas hydrostatic, lub zog tensile thiab txias dabtsi yog khoov, kev ua haujlwm ntawm vuam seam yuav tsum ua tau raws li qhov yuav tsum tau ua.

Lub hom phiaj tseem ceeb:
Lub kauv steel yeeb nkab feem ntau yog siv rau cov roj thiab cov roj nkev xa mus.

Txheej txheem ntau lawm:
(1) Cov khoom siv raw: steel coil, vuam hlau thiab flux.Kev tshuaj xyuas lub cev thiab tshuaj nruj nruj yuav tsum tau ua ua ntej kev tsim khoom.
(2) Lub taub qab vuam lub taub hau thiab tus Tsov tus tw ntawm lub kauj los ua ob lub coils sib koom ua ke, tom qab ntawd siv ib lub xaim lossis ob lub xov hlau submerged arc vuam, thiab tsis siv neeg submerged arc vuam yog siv rau vuam tom qab dov rau hauv cov yeeb nkab steel.
(3) Ua ntej tsim, cov hlau sawb yuav tsum tau leveled, trimmed, npaj, deg huv si, thauj thiab ua ntej khoov.
(4) Lub tshuab hluav taws xob tiv tauj lub ntsuas hluav taws xob yog siv los tswj lub siab ntawm lub tog raj kheej nias ntawm ob sab ntawm lub conveyor kom ntseeg tau tias kev thauj mus los ntawm cov sawb hlau zoo.
(5) Rau txoj kev yob, siv kev tswj sab nraud lossis kev tswj sab hauv.
(6) Siv cov khoom siv vuam sib txawv los xyuas kom meej tias qhov sib txawv ntawm qhov vuam ua tau raws li qhov yuav tsum tau ua ntawm vuam, tom qab ntawd cov yeeb nkab txoj kab uas hla, kev sib tsoo thiab vuam qhov sib txawv tuaj yeem tswj tau nruj me ntsis.
(7) Ob leeg vuam sab hauv thiab sab nraud vuam txais yuav American Lincoln Electric vuam tshuab rau ib tug hlau los yog ob lub xov hlau submerged arc vuam, thiaj li tau txais kev vuam ruaj khov.
(8) Tag nrho cov vuam seams raug tshuaj xyuas los ntawm on-line nruam ultrasonic tsis siv neeg qhov tsis pom kev los xyuas kom meej 100% NDT xeem npog tag nrho cov kauv vuam seams.Yog tias muaj qhov tsis xws luag, nws yuav cia li ceeb toom thiab tshuaj tsuag cov cim, thiab cov neeg ua haujlwm tsim khoom yuav kho cov txheej txheem tsis tu ncua txhua lub sijhawm kom tshem tawm qhov tsis xws luag hauv lub sijhawm.
(9) Cov yeeb nkab steel yog txiav rau hauv ib qho los ntawm lub tshuab txiav.
(10) Tom qab txiav rau hauv ib lub yeeb nkab steel, txhua batch ntawm cov yeeb nkab steel yuav raug soj ntsuam nruj heev los xyuas cov khoom siv kho tshuab, tshuaj lom neeg muaj pes tsawg leeg, fusion mob, nto zoo ntawm cov yeeb nkab steel thiab NDT kom ntseeg tau tias cov yeeb nkab ua cov txheej txheem. yog tsim nyog ua ntej nws tuaj yeem muab tso rau hauv kev tsim khoom.
(11) Cov khoom uas muaj qhov tsis txaus ntseeg nrhiav pom cov cim ntawm lub vuam seam yuav tsum tau kuaj xyuas los ntawm phau ntawv ultrasonic thiab X-ray.Yog tias muaj qhov tsis xws luag, tom qab kho, cov yeeb nkab yuav tsum raug rau NDT dua kom txog thaum nws tau lees paub tias qhov tsis xws luag raug tshem tawm.
(12) Cov yeeb nkab ntawm lub taub qab vuam seam thiab T-joint sib tshuam kauv vuam seam yuav tsum raug tshuaj xyuas los ntawm X-ray TV lossis tshuaj xyuas zaj duab xis.
(13) Txhua cov yeeb nkab steel yuav raug kuaj hydrostatic.Kev ntsuas siab thiab lub sijhawm yog nruj me ntsis tswj los ntawm lub khoos phis tawj kuaj xyuas cov khoom siv steel yeeb nkab dej siab.Cov ntsuas ntsuas tau raug luam tawm thiab kaw.
(14) Cov yeeb nkab kawg yog machined kom raug tswj lub perpendicularity, bevel kaum sab xis thiab hauv paus lub ntsej muag.
