Qib B yog qhov feem ntau tau teev tseg ntawm peb - nws muaj lub ntsiab lus muaj zog nce qib ntawm Qib A yam tsis muaj kev sib tw nruj dua thiab txo qis kev lag luam ductility - tawm uas tuaj nrog Qib C.
Kub-Formed vs. Txias-Formed: Qhov txawv uas qhov tseem ceeb
A501 feem ntau tsis meej pem nrog ASTM A500 vim hais tias ob qho tib si npog carbon steel structural tubing nyob rau hauv tib daim duab thiab ib tug zoo sib xws zog ntau yam. Qhov txawv uas tseem ceeb rau kev tsim thiab kev tsim khoom tsis yog cov ntawv qib - nws yog txheej txheem tsim nws tus kheej.
A500yog txias-tsim: strip steel yog yob- ua rau hauv cov duab thiab welded ntawm qhov kub thiab txias. Qhov kev ua haujlwm txias no ntsuas qhov ua kom muaj zog, tshwj xeeb tshaj yog nyob rau ntawm cov ces kaum ntawm cov duab plaub thiab cov duab plaub, uas yog ib feem ntawm vim li cas A500 cov txiaj ntsig tau tshaj tawm tuaj yeem saib kev sib tw nrog A501 txawm tias pib los ntawm kev sib piv ntawm cov chemistry.
A501yog kub- tsim: lub raj yog zoo li tus thiab welded ntawm siab kub, ces tso cai rau txias yam tsis muaj strain- hardening nyhuv txias ua hauj lwm tsim. Qhov tshwm sim yog ib seem metallurgically ntau dua - tsis muaj xauv- nyob rau hauv seem kev ntxhov siab los ntawm txias dabtsi yog khoov, zoo ib yam li grain qauv nyob ib ncig ntawm tag nrho cov perimeter, thiab txhua yam khoom uas tsis txawv ntawm lub tiaj lub ntsej muag thiab cov ces kaum raws li ib tug txias - tsim seem tus tau.
Cov txheej txheem tsis yog categorically "zoo dua." Txias-tsim A500 nyiam yeej ntawm tus nqi thiab lub sijhawm ua haujlwm rau cov qauv kab ke thiab thav duab. Kub- tsim A501 zoo li yuav tsum tau teev nyob rau hauv cov khoom sib xws nyob ib puag ncig khoov muaj teeb meem ntau dua - hnyav welded trusses, tus choj cov tswv cuab raug qaug zog los yog dynamic loading, thiab cov seem uas yuav pom cov cua kub tseem ceeb los ntawm kev vuam, qhov chaw txias - ua hauj lwm ces kaum yog feem ntau nyob rau hauv lub zos embrittlement dua ib tug kub {
Txoj Kev Tsim Nyog Tsis Muaj Neeg Nug Txog: SAW
A501 tso cai submerged arc vuam raws li txoj kev tsim khoom, ntxiv rau seamless, rauv-tooj vuam, thiab hluav taws xob- tsis kam vuam. SAW qhib qhov loj dua thiab cov phab ntsa hnyav dua li ERW ntau lawm feem ntau nce mus txog kev lag luam, uas yog vim li cas A501 tshwm sim ntau dua li A500 ntawm qhov loj - txoj kab uas hla choj piling thiab cov kab ntawv hnyav - tus qauv nws tus kheej haum rau txoj kev tsim khoom xav tau kom mus txog qhov ntawd.
Kev ntsuam xyuas cuam tshuam yog ntxiv, tsis siv
Qib B thiab C muaj qhov kev xaiv ntxiv uas yuav tsum tau ua (S1) rau Charpy V- ntsuas qhov cuam tshuam ntawm qhov ntsuas kub qis, thiab phab ntsa thicknesses ntawm 0.250 in. (6.3 mm) lossis tsawg dua yog raug zam los ntawm kev sim cuam tshuam nkaus xwb tshwj tsis yog raug hu tawm. Qhov no yog qhov nthuav dav tsim nyog chij vim tias nws yooj yim rau kev xav tias "qib qauv" tuaj nrog cov ntawv pov thawj toughness - nws tsis yog, tshwj tsis yog tias daim ntawv xaj xaj tshwj xeeb hu rau S1 thiab hais txog qhov ntsuas kub thiab xav tau lub zog nqus. Daim ntawv pov thawj zeb uas tsis muaj kev cuam tshuam cov txiaj ntsig tsis yog qhov tsis ua raws li tus qauv txiav txim; Nws tsuas yog qhov tshwm sim thaum S1 tsis tau teev tseg.
Ib rooj plaub uas tus txheej txheem tsim, tsis yog qib, ua rau rov tsim dua
Tus neeg tsim khoom sib tw cov qauv welded truss muaj cov khoom siv coj los ua nyob ib puag ncig A500 Qib B tubing, tom qab ntawd hloov A501 Qib B thaum lub sijhawm kev yuav khoom ntawm qhov kev xav tias sib piv cov txiaj ntsig thiab cov lej tensile ua rau ob qho kev hloov pauv. Tus engineer ntawm cov ntaub ntawv chij tau hloov pauv thaum lub khw kos duab tshuaj xyuas: lub truss txoj kev sib txuas tsim tau xav tias lub kaum ntse ntse txhim kho qhov zoo ntawm qhov txias - tsim A500 ntu ntawm cov phaj gusset welds, thiab kub - tsim A501 tsis nqa tib lub kaum sab xis. Cov qhab nias sib npaug ntawm daim ntawv; cov txheej txheem tsim tsis tau, thiab qhov kev sib txuas nthuav dav xav tau qhov thib ob saib ua ntej fabrication pib. Tsis muaj ib yam dab tsi tawm ntawm spec - qhov tsis sib haum xeeb nyob nruab nrab ntawm cov txheej txheem tsim thiab qhov tau txiav txim.
FAQ
Q: Puas yog A501 muaj zog dua A500 ntawm tib daim ntawv qib?
A: Tsis tas li - luam tawm yam tsawg kawg nkaus thiab cov nqi tensile sib txawv me ntsis ntawm ob tus qauv txawm tias ntawm cov ntawv qib sib luag, thiab A500 qhov txias txias- cov ces kaum tuaj yeem nqa lub zog hauv zos ntxiv uas A501 qhov kub- cov seem tsim tsis rov ua dua. Ob qho qauv yuav tsum muab piv rau lawv qhov tseeb qhov tseem ceeb, tsis suav tias yog sib npaug vim cov ntawv qib sib luag.
Q: A501 thiab A500 puas tuaj yeem hloov tau rau ib leeg ntawm ib qhov project?
A: Tsuas yog tias tus engineer ntawm cov ntaub ntawv tau lees tias tus tsim tsis cia siab rau qhov txias- tsim- cov khoom tshwj xeeb, thiab qhov kev ua tiav, qhov loj, thiab phab ntsa thickness yeej muaj nyob rau hauv tus qauv hloov pauv.
Q: Puas yog A501 tubing ib txwm xav tau kev sim cuam tshuam?
A: Tsis yog. Kev ntsuam xyuas qhov cuam tshuam raws li A501 yog qhov yuav tsum tau ua ntxiv (S1) uas tsuas yog siv thaum txiav txim tshwj xeeb, thiab phab ntsa thicknesses ntawm 0.250 in. lossis tsawg dua yog raug zam txawm tias. Daim ntawv pov thawj uas tsis muaj kev cuam tshuam cov txiaj ntsig yog qhov qub tshwj tsis yog S1 tau raug hu rau ntawm daim ntawv xaj khoom.
Q: Dab tsi yog qhov txawv ntawm qhov cub- vuam vuam thiab hluav taws xob- vuam vuam nyob rau hauv A501?
A: Ob leeg tau tso cai rau kev tsim khoom, tab sis rauv - pob tw (nruam) vuam yog qhov qub, feem ntau qis dua - tus nqi txheej txheem feem ntau txwv rau qhov me me, thaum ERW thiab SAW npog cov kab loj dua thiab hnyav dua - phab ntsa ntau dua pom hauv cov qauv siv niaj hnub no.
