Loj - txoj kab uas hla kauv welded kav muaj txoj kab uas hla ntau dua 400 mm thiab tuaj yeem ncav cuag ob peb meters hauv qhov dav. Kauv steel kav yog tsim los ntawm dabtsi yog khoov thiab tsim steel sawb coils, ua raws li welding. Cov yeeb nkab steel no, nrog nws qhov tshwj xeeb kauv weld seam, muaj lub zog siab thiab rigidity. Tsis tas li ntawd, cov kauv weld seam yog zoo ib yam thiab muaj qhov tsim nyog kev ntxhov siab ntau tshaj qhov ncaj seam weld seam.
Loj -diameter kauv welded yeeb nkab txheej txheem:
Kauv steel kav yog tsim los ntawm steel sawb coils raws li raw cov ntaub ntawv, tsim los ntawm txias extrusion, thiab welded siv ib tug tsis siv neeg ob - hlau ob - sab submerged arc vuam txheej txheem. Cov txheej txheem ntau lawm yog raws li nram no:
- Raw cov ntaub ntawv, uas yog steel sawb coils, vuam hlau, thiab flux, yuav tsum tau ua nruj me ntsis rau lub cev thiab tshuaj ntsuam xyuas ua ntej yuav siv.
- Qhov kawg ntawm cov hlau sawb yog pob tw -welded siv ib zaug - hlau los yog ob - hlau submerged arc vuam. Tom qab dov mus rau hauv cov yeeb nkab steel, tsis siv neeg submerged arc vuam yog siv rau kev sib txuas ntxiv.
- Ua ntej kev tsim, cov hlau sawb undergoes leveling, ntug trimming, ntug planing, deg tu, conveying, thiab pre-bending. (4) Lub siab ntawm lub tog raj kheej hydraulic ntawm ob sab ntawm lub conveyor yog tswj los ntawm lub tshuab hluav taws xob tiv tauj lub ntsuas, kom ntseeg tau tias kev xa tawm ntawm cov hlua hlau.
- Sab nraud lossis sab hauv kev tswj cov menyuam txoj kev yog siv.
- Weld gap control device yog siv los xyuas kom meej tias qhov sib txawv weld raws li qhov xav tau ntawm vuam; yeeb nkab txoj kab uas hla, misalignment, thiab weld gap yog tag nrho cov nruj tswj.
- Ob leeg sab hauv thiab sab nraud siv Lincoln Electric vuam tshuab los ntawm Teb Chaws Asmeskas rau ib zaug - hlau los yog ob npaug - hlau submerged arc vuam, yog li tau txais kev ruaj khov vuam specifications.
- Tag nrho cov welded seams raug tshuaj xyuas los ntawm ib qho online txuas ntxiv ultrasonic tsis siv neeg qhov tsis pom kev, kom ntseeg tau 100% tsis yog -kev ntsuas kev puas tsuaj ntawm cov kauv welds. Yog tias pom muaj teeb meem, lub tswb tsis siv neeg tau tshwm sim thiab lub cim raug txau, tso cai rau cov neeg ua haujlwm tsim kho cov txheej txheem tsis raug thiab tshem tawm qhov tsis xws luag tam sim ntawd.
- Lub tshuab cua plasma yog siv los txiav cov yeeb nkab steel rau hauv ib tus neeg. (10) Tom qab raug txiav rau hauv ib tus neeg cov kav hlau, thawj peb cov kav dej ntawm txhua pawg tau ua haujlwm nruj ua ntej - dhau qhov kev tshuaj xyuas. Qhov no suav nrog kev tshuaj xyuas cov khoom siv hluav taws xob, tshuaj lom neeg muaj pes tsawg leeg, fusion raws li txoj cai, thiab qhov zoo ntawm qhov vuam, nrog rau tsis yog- kev sim ua kom puas tsuaj los xyuas kom meej tias cov txheej txheem tsim cov yeeb nkab yog raws li tus qauv ua ntej kev tsim khoom tuaj yeem pib.
- Cov cheeb tsam uas muaj cov cim tsis pom kev txuas ntxiv ultrasonic ntawm qhov vuam yog manually tshuaj xyuas siv ultrasonic thiab X-ray txoj kev. Yog tias pom muaj qhov tsis xws luag, lawv raug kho thiab tom qab ntawd raug rau qhov tsis yog - kev sim ua kom puas tsuaj dua kom txog rau thaum cov khoom tsis raug lees paub tias yuav raug tshem tawm.
- Tag nrho cov kav dej uas muaj pob tw welds ntawm cov sawb hlau thiab T- cov pob qij txha cuam tshuam nrog cov kab welds raug tshuaj xyuas siv X-ray TV lossis radiography.
- Txhua cov yeeb nkab steel tau dhau los ntawm kev ntsuas hydrostatic siab, nrog radial sealing thov. Kev ntsuas siab thiab lub sijhawm yog tswj hwm nruj los ntawm lub khoos phis tawj- tswj kev ntsuas dej siab hydrostatic. Cov ntsuas ntsuas tau raug luam tawm thiab kaw.
- Cov yeeb nkab kawg yog machined los xyuas kom meej tswj qhov kawg ntawm lub ntsej muag perpendicularity, bevel kaum sab xis, thiab blunt ntug.
Qhov zoo:
- High Pressure Resistance: Vim nws qhov tshwj xeeb spiral weld qauv, kev ntxhov siab tau muab faib ua qhov sib npaug thoob plaws hauv cov yeeb nkab lub cev, ua rau lub raj xa dej tuaj yeem tiv taus siab sab hauv thiab sab nraud, ua rau muaj kev nyab xeeb siab.
- Flexible Specifications: Piv nrog rau cov kav hlau steel uas tsim los siv lwm cov txheej txheem, cov kav dej welded muab kev hloov pauv ntau dua hauv txoj kab uas hla thiab phab ntsa tuab, tso cai rau kev tsim cov khoom tsis yog{0}} cov khoom tsim raws li qhov yuav tsum tau ua.
- Lub zog siab thiab Kev Pabcuam Ntev: Siv cov-cov hlau zoo li cov khoom siv raw thiab ua cov txheej txheem tsim khoom nruj thiab tiv thaiv- kev kho corrosion, cov kav dej tiav lawm muaj lub zog zoo thiab lub neej ua haujlwm ntev, hloov mus rau ntau qhov chaw geological thiab climatic ib puag ncig.
- Economical Advantages: Raws li lub hauv paus ntsiab lus ntawm kev ua tau raws li qhov yuav tsum tau ua, loj - txoj kab uas hla kauv steel kav feem ntau muab kev lag luam zoo dua hauv kev tsim khoom thiab kev teeb tsa cov nqi, uas yog qhov tseem ceeb rau kev tswj hwm tag nrho cov peev ntawm loj - cov phiaj xwm loj.
