General Welded Pipes: General welded kav yog siv rau kev xa cov kua dej uas tsis tshua muaj siab. Lawv yog ua los ntawm Q195A, Q215A, thiab Q235A steel, los yog lwm yam yooj yim weldable me me hlau. Cov kav dej no tau txais kev ntsuam xyuas hydrostatic, khoov, thiab flattening, nrog rau cov kev cai tshwj xeeb rau qhov zoo. Feem ntau, lawv tau muab nyob rau hauv qhov ntev li ntawm 4 mus rau 10 meters, feem ntau yuav tsum tau muab faib ua feem (los yog ob npaug rau scaling) rau kev thauj mus los. Qhov nominal txoj kab uas hla (hauv millimeters los yog nti) ntawm welded kav txawv ntawm lawv cov specifications. Nyob ntawm phab ntsa thickness, muaj ob hom: txheem thiab ntxiv-thick. Cov kav dej kuj tau muab cais ua cov xov los yog tsis yog xov raws li cov duab ntawm lawv qhov kawg, txhais qhov ntev ntawm cov kav hlau welded.
Dab tsi yuav tsum tau ceev faj thaum siv cov kav hlau ncaj seam? Cia peb qhia luv luv qee cov ntsiab lus tseem ceeb uas yuav pab tau koj.
Kev txhim kho thiab siv cov kav hlau ncaj nraim yuav tsum tau ua raws li cov txheej txheem nruj thiab ua raws li cov txheej txheem ua haujlwm kom muaj kev nyab xeeb thiab zoo, suav nrog cov xwm txheej tiag tiag. Thaum siv dav dav, xyuam xim rau cov ntsiab lus hauv qab no:
Kev npaj ua ntej siv cov yeeb nkab ncaj seam hlau
Xyuas kom tseeb tias cov yeeb nkab trench raug khawb thiab cov yeeb nkab qhov dej tau tsim kom zoo.
Muab txhua yam tsim nyog ncaj seam steel kav thiab cov cuab yeej, suav nrog cov tshuab vuam, txiav tshuab, hluav taws xob rauj, tshuab polishing, thiab lwm yam, hauv kev npaj.
Pib installation tsuas yog tom qab ua tiav tag nrho cov kev npaj ua haujlwm.
Prefabricate yeeb nkab txhawb nqa raws li kev tsim cov duab kos thiab qhov chaw, xuas nrig ntaus thiab shear raws li tus qauv tsim thiab qhov chaw yuav tsum tau, polish grooves nrog lub tshuab polishing, thiab tom qab ntawd txuas nrog vuam.
Cov kev xav tau zoo rau kev siv
Tsis txhob welding ceg kav ntawm weld seams thiab tsis txhob welding ntawm khoov.
Qhov sib txawv rau cov ntsia hlau ntsia yuav tsum tsawg dua 3 hli ib 'meter', thiab kab rov tav installation deviations yuav tsum tsawg dua 1 hli.
Vuam yuav tsum ncaj, nrog ua tiav welds, thiab weld nto yuav tsum tsis txhob hlawv-dhau thiab tawg.
