A106gr.B uruganda rukora ibyuma bitagira ibyuma
Umuyoboro w'icyuma ASTM A106 ni uw'icyuma gisanzwe cy'Abanyamerika, harimo a106-a na a106-b. Iyambere ihwanye nu rugo 10 # ibikoresho, naho ibyanyuma bihwanye na 20 # ibikoresho byo murugo. Nibintu bisanzwe byuma bya karubone kandi nikimwe mubikoresho bisanzwe bikoreshwa. ASTM A106 umuyoboro wicyuma udafite icyerekezo kirimo inzira ebyiri: gushushanya imbeho no kuzunguruka. Usibye uburyo butandukanye bwo gukora, buratandukanye muburyo bwuzuye, ubwiza bwubuso, ingano ntoya, imiterere yubukanishi n'imiterere yubuyobozi. Ikoreshwa cyane muri peteroli, inganda z’imiti, amashyiga, sitasiyo y’amashanyarazi, ubwato, gukora imashini, imodoka, indege, ikirere, ingufu, geologiya, ubwubatsi, inganda za gisirikare n’izindi nganda.
Uburyo bwo kubara ASTM A106 yo kwihanganira umuvuduko wicyuma kitagira icyuma
S = 8; P iri munsi ya 17.5MPa umuyoboro wicyuma udafite icyuma, s nikintu cyumutekano cyumuyoboro wicyuma udafite kashe, kandi uburebure bwurukuta ni 3mm,
Umuvuduko wemewe wumuyoboro P = (2) * σ / S * δ) / D.
Aho: umuvuduko ni p naho ubugari bwurukuta ni δ, Numuvuduko ntarengwa wumuyoboro wicyuma utagira ikizinga?
Reka imbaraga zingana zibintu zibe σ, Zhan Rongrong yamenye ko diameter yinyuma yumuyoboro ari D;
Umuyoboro w'urukuta rw'umuyoboro δ = (P * D) / (2 * σ / S)
Aho s ni ibintu byumutekano;
Kuberako P iri munsi ya 7MPa, Zhan Jirong yamenye ko s yatoranijwe nka s = 4;
Duhitamo ibintu byumutekano nka s = 6; Imbaraga zingana zibyuma 20 ni 410mpa, isoko ryibyuma, na diameter yo hanze yumuyoboro ni d
Umuyoboro usanzwe wumunyamerika ni umurongo muremure wibyuma bifite igice cyuzuye kandi ntaho bihuriye. Umuyoboro w'icyuma ufite igice cyuzuye kandi ukoreshwa cyane nk'umuyoboro wo gutanga amazi. Ibipimo ngenderwaho byabanyamerika bidafite icyuma, nkumuyoboro wo kugeza peteroli, gaze gasanzwe, gaze, amazi nibikoresho bikomeye. Ugereranije nicyuma gikomeye nkicyuma kizengurutse, umuyoboro wibyuma ufite kunama hamwe nimbaraga za torsional hamwe nuburemere bworoshye. Nicyuma cyubukungu. Ikoreshwa cyane mugukora ibice byubatswe hamwe nubukanishi, nkumuyoboro wamavuta ya peteroli, icyuma gikwirakwiza imodoka, ikinga ryamagare hamwe nicyuma gikoreshwa mubwubatsi. Gukora ibice byimpeta hamwe nu miyoboro yicyuma birashobora kunoza imikoreshereze yibikoresho, koroshya uburyo bwo gukora, no kubika ibikoresho namasaha yo gutunganya, nkimpeta zizunguruka, amaboko ya Jack, nibindi. Imiyoboro yicyuma yakoreshejwe cyane mubikorwa. Umuyoboro w'icyuma nawo ni ikintu cy'ingirakamaro ku bwoko bwose bw'intwaro zisanzwe. Imbunda y'imbunda na barrale bigomba gukorwa mu miyoboro y'icyuma. Umuyoboro w'icyuma urashobora kugabanywamo umuyoboro uzengurutse hamwe n'umuyoboro udasanzwe ukurikije ahantu hatandukanye ndetse n'imiterere. Kuberako agace kazengurutswe nini nini muburyo bwo kuzenguruka bingana, amazi menshi arashobora gutwarwa numuyoboro uzenguruka. Mubyongeyeho, iyo igice cyimpeta gikorewe umuvuduko wimbere cyangwa hanze, imbaraga zirasa. Kubwibyo, imiyoboro myinshi yicyuma ni imiyoboro izengurutse.
Mu miyoboro isanzwe y'Abanyamerika, ASTM A53 gr. B umuyoboro wicyuma udafite intego kubwintego rusange, ASTM A106 / A53 gr. B umuyoboro wicyuma na chamfereri, bs1387-1985 Ubwongereza busanzwe bwa ERW bwumuvuduko mwinshi wogosha hamwe numuyoboro wa galvanis, ASTM A333 - 40 ℃ - 101 temperature ubushyuhe buke butagira icyuma, ASTM A179 umuyoboro wicyuma udahindura ubushyuhe hamwe na kondenseri. Uburebure bw'icyuma: 5.8m, 6m na 12m, Irashobora kandi gupimwa ukurikije ibyo abakoresha bakeneye.
Diameter yo hanze yibicuruzwa ni 1/2 "- 28", 21.3-711.2mm, naho uburebure bwurukuta ni sch30, sch40, STD, XS, sch80, sch160, XXS, nibindi umuyoboro udafite ikizinga urashobora gukorerwa anti anti -Kuvura ruswa nkuko bisabwa, hamwe na capitike ya pulasitike ya pulasitike kumpande zombi, gutondeka nkuko bisabwa, no kugenzura ibicuruzwa.
