Vim li cas welded yeeb nkab yog dav siv
Welded steel yeeb nkab tso nyiaj rau feem ntau ntawm cov yeeb nkab tsim tawm thoob ntiaj teb vim tias nws yog kev lag luam ntau dua li cov yeeb nkab seamless rau ntau qhov ntau thiab tsawg. Peb lub ntsiab welding technologies dominates ntau lawm: high zaus hluav taws xob kuj vuam, hu ua ERW; ob -sab submerged arc vuam, hu ua DSAW; thiab hluav taws xob fusion vuam, hu ua EFW. Txhua tus txheej txheem tsim cov qauv sib txawv ntawm cov seam thiab ua haujlwm sib txawv ntawm kev ua lag luam.
ERW Yeeb Nkab Technology
ERW yeeb nkab yog tsim los ntawm sawb los yog phaj nyob rau hauv ib tug nruam zeb qhov twg cov npoo yog rhuab los ntawm high zaus tam sim no thiab forged ua ke nyob rau hauv siab tsis muaj muab tub lim hlau. Lub weld yog ib daim ntawv cog lus forged nrog rau qhov nqaim tshav kub cuam tshuam cheeb tsam. ERW yog ceev thiab pheej yig rau txoj kab uas hla mus txog 610 hli, thiab cov mills niaj hnub no ua tau zoo heev seam toughness, ua ERW yeeb nkab txheem rau kev faib roj thiab cov kab nruab nrab siab.
DSAW Yeeb Nkab Technology
DSAW yeeb nkab yog welded nrog submerged arc txheej txheem los ntawm ob qho tib si sab nraud thiab sab hauv, ua kom sib sib zog nqus, tag nrho - nkag mus rau weld nrog pom weld cap reinforcement. Cov txheej txheem yog siv rau txoj kab uas hla loj longitudinal welded yeeb nkab thiab rau kauv welded yeeb nkab. DSAW yog cov thev naus laus zis tseem ceeb rau cov kab loj loj ntawm cov roj thiab cov roj xa hluav taws xob thiab cov txheej txheem piling, nrog txoj kab uas hla ntawm li 406 hli nce mus.
EFW Tube Technology
EFW yeeb nkab yog tsim los ntawm hluav taws xob fusion vuam, feem ntau nrog cov pa roj tungsten arc hauv paus hla dhau los ntawm kev muab tub lim, tsis muaj siab siv rau kev sib koom ua ke. EFW yog siv rau kev khiav me me ntawm cov ntaub ntawv tshwj xeeb thiab qhov ntau thiab tsawg, suav nrog cov hlau tsis muaj steel thiab cov yeeb nkab hlau rau qhov kub thiab txias thiab corrosive kev pab cuam, qhov twg cov vuam hlau chemistry yuav tsum phim cov khoom hauv paus meej.
Kev sib piv ntawm Seam Quality
Lub ERW seam tsis muaj cov hlau txuas ntxiv thiab yuav luag tsis pom tom qab ua tiav, tab sis nws tuaj yeem ua rau muaj kev cuam tshuam rau seam tsis xws luag yog tias lub zeb tsis tswj tau zoo. DSAW welds tau pom thiab tuaj yeem kuaj xyuas los ntawm kev kuaj hluav taws xob thiab kev kuaj ultrasonic, thiab lawv tuaj yeem tiv taus cov phab ntsa hnyav dua li ERW. EFW welds kuj tseem tuaj yeem kuaj xyuas thiab tuaj yeem ua nrog ntau qhov kev hla mus rau qhov zoo tshaj plaws.
Qhov Loj thiab Daim Ntawv Thov Ntau Yam
ERW npog me me thiab nruab nrab diameters nrog phab ntsa tuab txog li 16 hli. DSAW npog cov kab loj loj thiab cov phab ntsa tuab, los ntawm 406 hli mus rau ntau tshaj 2500 hli. EFW feem ntau yog siv rau cov ntaub ntawv tshwj xeeb hauv qhov ntau thiab tsawg ntawm 60 hli txog 900 hli. Kab yeeb nkab, dej yeeb nkab, piling, boiler thiab tshav kub exchanger tubing tag nrho cov txheej txheem nyiam raws li qhov loj me thiab kev pabcuam.
Cov lus nug nquag
Cov txheej txheem welded yeeb nkab twg muaj zog tshaj?Tag nrho peb tsim cov yeeb nkab uas ua tau raws li qhov xav tau ntawm kev tsim qauv siab; qhov kev xaiv nyob ntawm txoj kab uas hla, phab ntsa thickness thiab cov khoom es tsis muaj zog kiag li.
ERW yeeb nkab puas siv tau rau cov roj thiab roj xa mus?Yog lawm, niaj hnub ERW yeeb nkab tau txais kev pom zoo dav dav rau kev xa tawm roj thiab roj thaum tsim thiab sim rau API 5L cov cai.
Qhov txawv ntawm DSAW thiab EFW yog dab tsi?DSAW siv submerged arc vuam los ntawm ob sab nrog lub siab - pub dawb muab tso rau ntawm cov yeeb nkab tsim, thaum EFW yog ib lo lus dav dav rau hluav taws xob fusion vuam, feem ntau nrog cov txheej txheem arc thiab tsis muaj kev siv tshuab.
Vim li cas ERW pheej yig dua li seamless yeeb nkab?ERW yog cov txheej txheem kev kub ceev nruam nrog cov khoom pov tseg tsawg dua thiab tsis muaj kev ua haujlwm tho, uas txo cov nqi tsim khoom.
ERW seam soj ntsuam li cas?Lub seam raug tshuaj xyuas hauv online los ntawm eddy tam sim no los yog kuaj ultrasonic, thiab cov weld kuj yog kuaj los ntawm kev puas tsuaj flattening thiab khoov kev ntsuam xyuas.
