A106gr.B seamless steel yeeb nkab chaw tsim tshuaj paus muag ncaj qha
ASTM A106 seamless steel yeeb nkab belongs rau American standard steel yeeb nkab, suav nrog a106-a thiab a106-b. Tus qub yog sib npaug rau cov khoom siv hauv tsev 10 #, thiab tom kawg yog sib npaug rau cov khoom siv hauv tsev 20 #. Nws belongs rau cov pa roj carbon zoo tib yam series thiab yog ib qho ntawm cov khoom siv feem ntau. ASTM A106 seamless steel yeeb nkab suav nrog ob txheej txheem: kos duab txias thiab kub dov. Ntxiv rau cov txheej txheem ntau lawm, lawv sib txawv ntawm qhov tseeb, qhov zoo ntawm qhov chaw, qhov tsawg kawg nkaus, cov khoom siv kho tshuab thiab cov qauv tsim. Nws yog dav siv hauv roj av, tshuaj lom neeg kev lag luam, boiler, fais fab chaw nres tsheb, nkoj, machinery manufacturing, tsheb, aviation, aerospace, zog, geology, kev tsim kho, tub rog kev lag luam thiab lwm yam lag luam.
ASTM A106 txoj kev suav rau cov kabmob siab ntawm seamless steel yeeb nkab
S = 8; P yog tsawg dua 17.5MPa seamless steel yeeb nkab, s yog qhov zoo tshaj plaws seamless steel yeeb nkab, thiab phab ntsa thickness yog 3 hli,
Tso cai siab ntawm cov yeeb nkab P = (2) * σ / S * δ) / D
Qhov twg: lub siab yog p thiab phab ntsa thickness yog δ, Qhov siab tshaj plaws ntawm seamless steel yeeb nkab yog dab tsi?
Cia lub tensile lub zog ntawm cov khoom yog σ, Zhan Rongrong kawm tau hais tias lub sab nraud txoj kab uas hla ntawm cov yeeb nkab yog D;
Phab ntsa thickness δ = (P * D) / (2 * σ / S)
Qhov twg s yog qhov kev nyab xeeb;
Vim tias P tsawg dua 7MPa, Zhan Jirong kawm tau tias s raug xaiv raws li s = 4;
Peb xaiv qhov kev nyab xeeb raws li s = 6; Lub zog tensile ntawm 20 steel yog 410mpa, lub lag luam steel, thiab sab nraud ntawm cov yeeb nkab yog d
American standard steel yeeb nkab yog ib tug ntev sawb ntawm hlau nrog hollow seem thiab tsis muaj pob qij txha nyob ib ncig ntawm nws. Cov yeeb nkab steel muaj hollow seem thiab yog dav siv los ua cov raj xa dej. American standard seamless steel yeeb nkab qauv, xws li pipeline rau conveying roj, natural gas, roj, dej thiab ib co khoom siv. Piv nrog cov khoom siv hlau xws li cov hlau puag ncig, cov yeeb nkab steel muaj tib yam dabtsi yog khoov thiab torsional lub zog thiab lub teeb yuag. Nws yog ib qho kev lag luam steel hlau. Nws yog dav siv nyob rau hauv kev tsim cov khoom siv thiab cov khoom siv kho tshuab, xws li roj laum yeeb nkab, tsheb sib kis ncej, tsheb kauj vab ncej thiab steel scaffold siv hauv kev tsim kho. Kev tsim cov nplhaib nrog cov kav hlau tuaj yeem txhim kho kev siv cov khoom siv, ua kom yooj yim ntawm cov txheej txheem tsim khoom, thiab txuag cov ntaub ntawv thiab cov sijhawm ua haujlwm, xws li dov bearing rings, Jack tes tsho, thiab lwm yam. steel kav tau siv dav rau kev tsim khoom. Cov yeeb nkab steel kuj yog ib qho khoom siv tsis tau rau txhua yam riam phom. Cov phom phom thiab lub thoob yuav tsum tau ua los ntawm cov yeeb nkab steel. Cov yeeb nkab steel tuaj yeem muab faib ua cov yeeb nkab puag ncig thiab cov yeeb nkab tshwj xeeb raws li qhov sib txawv ntawm qhov sib txawv thiab cov duab. Vim tias thaj chaw ncig yog qhov loj tshaj plaws nyob rau hauv qhov xwm txheej ntawm qhov sib npaug, cov kua dej ntau tuaj yeem thauj tau los ntawm cov yeeb nkab ncig. Tsis tas li ntawd, thaum lub nplhaib seem raug rau sab hauv lossis sab nraud radial siab, lub zog sib txawv ntau dua. Yog li ntawd, feem ntau cov kav hlau steel yog cov kav dej puag ncig.
Ntawm American standard steel kav, ASTM A53 gr. B seamless steel yeeb nkab rau lub hom phiaj, ASTM A106 / A53 gr. B chamfered thiab chamfered steel yeeb nkab, bs1387-1985 British standard ERW high zaus welded yeeb nkab thiab galvanized yeeb nkab, ASTM A333 - 40 ℃ - 101 ℃ qis kub seamless steel yeeb nkab, ASTM A179 seamless steel yeeb nkab rau tshav kub exchanger thiab condenser. Hlau yeeb nkab ntev: 5.8m, 6m thiab mus txog 12m, Nws tseem tuaj yeem ntsuas raws li tus neeg siv xav tau.
Sab nraud txoj kab uas hla ntawm cov khoom yog 1/2 "- 28", 21.3-711.2mm, thiab cov phab ntsa thickness yog sch30, sch40, STD, XS, sch80, sch160, XXS, thiab lwm yam. seamless yeeb nkab yuav raug rau saum npoo los tiv thaiv. - kev kho corrosion raws li qhov yuav tsum tau ua, nrog cov yas yeeb nkab hau ntawm ob qho kawg, chamfering raws li qhov xav tau, thiab kev tshuaj xyuas cov khoom.
