Dab tsi Cold Expansion Tiag tiag hloov hauv cov yeeb nkab
- Roundness (lub voj voog):tawm ntawm - ntawm - cov yeeb nkab puag ncig yog thawb rov qab mus rau qhov tseeb hla hla- ntu, uas tseem ceeb ncaj qha rau kev sib haum xeeb - nce thiab rau phab ntsa raug - kev ntsuas kev ntxhov siab nyob rau hauv lub siab sab hauv.
- Qhov siab kam rau ua:expansion qhov loj me ntawm cov yeeb nkab mus rau ib qho nruj dua, rov ua dua zaum kawg OD dua li kev tsim ib leeg tuaj yeem ua tiav.
- Residual stress:qee qhov kev ntxhov siab kaw thaum lub sij hawm tsim thiab vuam yog relieved raws li cov yeeb nkab yog nthuav.
- Yield zog cwj pwm:qhov no yog tsim nyog ua kom meej txog ntau dua li glossing. Kev nthuav dav txias feem ntau ua rau cov yeeb nkab lub zog tensile tawm los me ntsis (strain hardening), tab sis nws kuj tuaj yeem ua kom paub cov nyhuv Bauschinger - txo qis hauv compressive yield zog nyob rau hauv cov kev taw qhia opposite rau cov ntaub ntawv strain. API 5L tso nyiaj rau qhov no hauv nws qhov kev xeem thiab qib kev tsim nyog, uas yog ib qho laj thawj daim ntawv pov thawj zeb rau cov yeeb nkab nthuav dav yuav tsum qhia qhov tseeb tshaj tawm -expansion mechanical test results es not only pre-expansion plate certs.
Tsis muaj qhov no ua rau txias -cov yeeb nkab nthuav dav "zoo dua" hauv qee qhov kev txiav txim siab - nws ua rau nws qhov loj me thiab cov tshuab ua kom pom tau ntau dua, uas yog qhov project loj cov kav dej xav tau rau kev teeb tsa thiab tsim qauv zoo ib yam - kev ua raws cai.

Kev Qhia Txog Kev Yuav Khoom: Cov lus nug tsim nyog nug ua ntej koj xaj
- Daim ntawv pov thawj zeb puas muaj kev cuam tshuam txog kev tshaj tawm -expansion zog, lossis tsuas yog lub phaj tuaj?Qhov no yog ib qho tseem ceeb tshaj plaws ntawm kev txheeb xyuas cov ntaub ntawv. Mechanical zog (yield zog, tensile zog, elongation) tuaj yeem hloov tom qab txias expansion. Daim ntawv pov thawj uas tsuas yog nqa cov phaj- zeb cov ntaub ntawv tsis qhia koj tias cov yeeb nkab tiav tau sim ntawm dab tsi.
- Qhov kev nthuav dav npaum li cas lub zeb no khiav, thiab nws puas tau sau tseg rau ib qho cua sov / ntau lossis ib qho kev piav qhia dav dav?Expansion ratio muaj feem xyuam rau ob qho tib si dimensional kam rau ua thiab residual mechanical zog. Reputable mills tuaj yeem qhia koj qhov piv txwv lawv khiav thiab rov qab nrog cov txheej txheem cov ntaub ntawv, tsis yog cov lus tshaj tawm uas "txias nthuav dav siv."
- Puas yog roundness (ovality) ntsuas thiab tshaj tawm, lossis tsuas yog nominal OD?Nominal OD nyob rau hauv kev ua siab ntev tsis tau lees tias kev ncig yog nyob rau hauv spec - nug tshwj xeeb rau ovality/roundness ntsuas cov ntaub ntawv, tshwj xeeb tshaj yog rau tuab -phab ntsa, loj- txoj kab uas hla txiav tawm qhov twg tawm - ntawm - roundness yog feem ntau yuav muaj teeb meem.
- Rau cov kev pabcuam qaub lossis siab dua-cov haujlwm hauv chav kawm, puas yog qhov kev nthuav dav tau raug txiav txim siab rau qhov yuav tsum tau ua kom tawv?Kev nthuav dav ntau dua tuaj yeem cuam tshuam qhov tawv thiab tawv ntawm txoj hauv kev uas tseem ceeb rau kev pabcuam qaub (NACE MR0175/ISO 15156) lossis siab -siab-chav kawm (PSL2) xaj. Qhov no yuav tsum yog ib feem ntawm kev sib tham nrog lub zeb, tsis xav tias yuav tsum tau ua raws li kev cai.
- Dab tsi NDT tau ua tom qab nthuav dav, tsis yog tom qab vuam?Ultrasonic kuaj ntawm weld seam thiab yeeb nkab lub cev yuav tsum tau lees paub tias tshwm sim tom qab lub expansion kauj ruam, txij li thaum expansion muaj peev xwm, nyob rau hauv lub hauv paus ntsiab lus, qhia los yog cuam tshuam qhov tsis xws luag ua ntej -expansion xeem yuav tsis ntes nyob rau hauv lawv lub xeev kawg.
- Puas yog qhov ntsuas hydrostatic siab thiab tuav lub sij hawm phim koj qhov project spec, tsis yog lub tshuab zeb generic default?Hydrotest parameters (siab, ntev) feem ntau teev rau ib qhov project / code (xws li, ASME B31.4, B31.8) es tsis yog sab laug rau lub zeb default - paub meej tias qhov no yog tsim rau hauv kev txiav txim, tsis xav.
- Yog tias qhov kawg yuav tsum tau rov ua dua - sib npaug lossis loj ntxiv rau qhov chaw haum - nce, puas suav nrog?Qee qhov haujlwm qhia txog qhov kawg ntxiv - qhov loj me lossis beveling tolerances nruj dua li lub zeb tus qauv txias nthuav dav xa mus rau lub cev. Qhia meej qhov no cais yog tias koj lub girth -welding tolerances yog nruj heev.
FAQ
Q: Puas yog qhov txias txias zoo ib yam li qhov txias txias?
A: Tsis yog. Cold forming yog hais txog shaping lub phaj rau hauv lub tog raj kheej (U, O, J, los yog C kauj ruam) yam tsis muaj cua sov cov hlau. Kev nthuav dav txias yog qhov txawv, tom qab kauj ruam - tom qab vuam - qhov uas twb tau tsim thiab welded yeeb nkab yog radially nthuav mus kho roundness thiab dimensional kam rau ua. Ob qho tib si tshwm sim ntawm qhov kub thiab txias, uas yog vim li cas qee zaum cov ntsiab lus tau conflated, tab sis lawv yog cov haujlwm sib txawv nrog lub hom phiaj sib txawv.
Q: Puas yog qhov kev nthuav dav txias ua rau lub vuam seam tsis muaj zog?
A: Tsis yog los ntawm - cov kauj ruam nthuav dav yog tus qauv, code- tau lees paub ib feem ntawm UOE / JCOE kev tsim khoom, thiab tom qab- nthuav dav NDT (UT, hydrostatic test) muaj tshwj xeeb kom paub meej tias qhov kev ntseeg ruaj khov ntawm cov txheej txheem. Cov teeb meem tshwm sim los ntawm kev tswj cov txheej txheem tsis zoo (kev nthuav dav ntau dhau, daim ntawv thov tsis sib xws) tsis yog los ntawm kev nthuav dav nws tus kheej.
Q: Vim li cas ho tsis ua kom cov yeeb nkab puag ncig txaus thaum tsim thiab hla kev nthuav dav?
A: Hauv kev xyaum, kev tsim cov phaj hnyav rau hauv lub tog raj kheej thiab vuam nws qhia txog kev hloov pauv txaus uas qhov kawg sizing kauj ruam yog qhov txhim khu kev qha thiab rov ua dua dua li sim tuav nruj roundness kam rau ua los ntawm kev tsim ib leeg, tshwj xeeb tshaj yog nyob rau hauv loj diameters thiab hnyav phab ntsa thicknesses.
Q: Puas yog qhov kev nthuav dav ntau dua txhais tau tias zoo dua?
A: Tsis tas yuav yog - nws txhais tau tias yuav tsum tau kho ntau dua lossis siv ntau dua, tsis tau txais cov yeeb nkab "zoo dua". Dab tsi tseem ceeb yog seb qhov piv txwv siv puas tsim nyog rau cov phab ntsa tuab, qib, thiab kev pabcuam, thiab seb cov khoom siv tshuab puas tseem ua tau raws li tus qauv tswj hwm.
