Andika E umuyoboro w'icyumabikozwe hakurikijweASTM A53kandi ikorwa hifashishijwe amashanyarazi-Kurwanya-gusudira (ERW) inzira.
Uyu muyoboro ukoreshwa cyane cyane mubukanishi nigitutu ariko nanone birakwiriye gukoreshwa nkumuyoboro rusange wo gutwara amavuta, amazi, gaze, numwuka.
Ubwoko bwa ASTM A53
Hariho ubwoko butatu:Andika F, Ubwoko E, na Ubwoko S..
Muri byo, umuyoboro wubwoko bwa E wakozwe na ERW inzira.
Niba ushaka kumenya byinshi kuriASTM A53, urashobora gukanda hano.
Ibyiciro
Ubwoko E bufite amanota abiri: Icyiciro A naIcyiciro B..
Ingano
Ingano yaASYM A53 ni DN 6-650.
Umusaruro waUbwoko E ni DN 20-650 DN.
Imiyoboro ya diametre iri munsi ya DN 20 ni nto cyane kubwoko bwa E. Kubwimpamvu za tekiniki ntaburyo bwo kubibyaza umusaruro, Ubwoko S, aribwo auburyo bwo gukora, ni Byakoreshejwe.
Uburyo bwo gukora ASTM A53 Ubwoko E.
Igikorwa cyo kubyaza umusaruro gikubiyemo gukora ibiceri byifashishije imizingo, gusudira ku mpande zishyushya ubushyuhe, gusudira gusudira, no gupima no kugorora gukora tebes.
Ibiranga ASTM A53 Ubwoko E Umuyoboro w'icyuma
Ifite ibibiri bibiri birebire gusudira imbere no hanze.Impande z'ibyuma bisudira haba imbere ndetse no hanze yu muyoboro mugihe cyo gukora kugirango habeho imbaraga no gufunga.
Imyenda y'imbere n'inyuma ntabwo bigaragara.Imbere yo gusudira imbere no hanze bisukurwa kugeza ku burebure bungana n'ubuso bwa pipe mugihe cyo kubyara, bigira uruhare mubigaragara muri rusange hamwe na hydrodinamike ishobora kuba ya pipe.
ASTM A53 Ubwoko E Ibigize imiti
Kuri buri kugabanuka kwa 0.01% munsi ya karubone ntarengwa, kwiyongera kwa 0,06% bya manganese hejuru yikirenga bizemerwa kugeza kuri 1.65%.
Cu, Ni, Cr, Mo, na V, nibintu bitanu hamwe bitarenze 1.00%.
ASTM A53 Ubwoko E Ibikoresho bya mashini
Ikizamini
Imiyoboro yo gusudira irwanya DN ≥ 200 igomba kugeragezwa hakoreshejwe ingero ebyiri zinyuranye, imwe hakurya ya weld indi ihabanye na weld.
| Urutonde | gushyira mu byiciro | Icyiciro A. | Icyiciro B. |

Ikizamini
Ku muyoboro, DN ≤50, uburebure buhagije bwumuyoboro bugomba kuba bushobora gukonjeshwa hakonje kugeza kuri 90 ° hafi ya mandel ya silindrike, umurambararo wacyo ukaba wikubye inshuro cumi na zibiri umurambararo w’inyuma w’umuyoboro, udatezimbere ibice ku gice na kimwe. gufungura gusudira.
Umuyoboro wikubye kabiri-hejuru ya DN 32 ntukeneye gukorerwa ikizamini.
"Double-extra-strong", bakunze kwita XXSni umuyoboro ufite uburebure bwurukuta rwihariye, rusanzwe rukoreshwa mubikorwa byinganda kugirango uhangane n’umuvuduko mwinshi hamwe n’ibidukikije bikaze.Uburebure bwurukuta rwuyu muyoboro ni muremure cyane kuruta umuyoboro usanzwe, bityo utanga imbaraga nyinshi kandi biramba.
Ikizamini cya Flattening
Ikizamini cyo gusibanganya kigomba gukorwa kumuyoboro usudutse hejuru ya DN 50 muburemere budasanzwe (XS) cyangwa bworoshye.
Uburyo bukurikira bwubushakashatsi bukoreshwa muburyo bwa E, Icyiciro A na B.
Mugihe cyo gukanda, gusudira bigomba gushyirwa kuri 0 ° cyangwa 90 ° kumurongo wicyerekezo cyingufu, bitewe nibisabwa byihariye.
Intambwe ya 1: Gerageza guhindagurika kwa weld.Ntihakagombye kubaho gucikamo cyangwa kumeneka hejuru yimbere cyangwa hanze yinyuma ya weld kugeza igihe intera iri hagati yamasahani iringaniye iri munsi ya bibiri bya gatatu bya diameter yo hanze yumuyoboro.
Intambwe ya 2: Komeza ukande hasi hanyuma ugerageze guhindagurika mukarere hanze ya weld.Ntabwo hagomba kubaho gucikamo cyangwa kumeneka hejuru yimbere cyangwa hanze yumuyoboro urenze weld kugeza igihe intera iri hagati yamasahani iringaniye iri munsi ya kimwe cya gatatu cya diametre yo hanze yumuyoboro, ariko ntibikubye inshuro eshanu z'ubugari bwa urukuta rw'umuyoboro.
Intambwe ya 3: Gerageza ubunyangamugayo bwibikoresho ukomeza gukanda kugeza igihe ikizamini cyacitse cyangwa inkuta zumuyoboro zihuye.Ibi bikoreshwa mugupima ibikoresho kubibazo nkibice byacitse, kutumvikana, cyangwa gusudira kutuzuye.
Ikizamini cya Hydrostatike
Ikizamini cya hydrostatike kigomba gukoreshwa, nta kumeneka kinyuze mu cyuma gisudira cyangwa mu miyoboro.
Umuyoboro wibibaya ugomba gupimwa hydrostatike kumuvuduko ukoreshwa watanzwe mumeza X2.2,
Umuyoboro uhujwe-hamwe-uhujwe bigomba kugeragezwa hydrostatike kumuvuduko ukoreshwa watanzwe mumeza X2.3.
Ku miyoboro y'ibyuma hamwe na DN ≤ 80, igitutu cy'ibizamini ntigishobora kurenga 17.2MPa;
Ku miyoboro y'icyuma hamwe na DN ＞ 80, umuvuduko w'ikizamini ntushobora kurenga 19.3MPa;
Ikizamini cy'amashanyarazi kidahwitse
Kubwoko bwa E na Ubwoko F Icyiciro B Imiyoboro DN ≥ 50, gusudira bigomba gukorerwa ibizamini byamashanyarazi bidasenya.
Igeragezwa ry'amashanyarazi ridasenya rigomba gukorwa hakurikijwe ibisobanuro E213, E273, E309 cyangwa E570.
Niba igeragezwa ry'amashanyarazi ridasenya ryakozwe, umuyoboro ugomba gushyirwaho "NDE".
ASTM A53 Ubworoherane Buringaniye
Ibipimo by'ibipimo byerekana imiyoboro hamwe n'imikorere y'umuyoboro
Ibyiza bya ASTM A53 Ubwoko E Umuyoboro
Kudoda gusudira ni uburyo bwo gusudira buhendutse cyane, bigatuma imiyoboro yo mu bwoko bwa E ihendutse kubyara kandi ikwiriye kubyazwa umusaruro.
Gahunda yo gusudira irwanya byihuse kandi irashobora kubyara ubudahwema, byongera umusaruro kandi bigabanya ibihe byo kuyobora.
Bitewe nuburyo bwiza bwubukanishi no kurwanya ruswa, ubu bwoko bwumuyoboro bukoreshwa cyane muburyo butandukanye bwo gutwara amazi, nk'amazi, gaze, hamwe na parike.
Isuderi irashobora gukorwa muburyo butagaragara hifashishijwe uburyo bwiza bwo gufata neza gusudira, ntibishobora gusa kunoza isura yumuyoboro ahubwo birashobora no kugabanya kurwanya umuvuduko wamazi uterwa nabasudira..
Porogaramu ya ASTM A53 Ubwoko E Umuyoboro w'icyuma
Gukoresha imiterere: Mu bwubatsi, umuyoboro w'icyuma A53 Ubwoko E ukoreshwa nkibigize imiterere nko kubaka inkunga na sisitemu ya truss.
Imiyoboro y'amazi: Ikoreshwa muri sisitemu yo gutanga amazi kumazu, harimo na sisitemu yo kumena umuriro.
Sisitemu ya parike: Mu nganda zinganda, iyi miyoboro yicyuma ikoreshwa muburyo bwo gutanga ibyuka, cyane cyane mubisabwa umuvuduko muke.
Gukwirakwiza gaze: Ikoreshwa mugutwara gaze karemano cyangwa iyindi myuka, cyane cyane muri sisitemu yo gutanga gazi ya komini n’amazu.
Ibimera: yo gutanga amavuta yumuvuduko muke, amazi, nindi miti.
Urusyo: gutanga ibikoresho bibisi nibicuruzwa byarangiye, kimwe no guta imyanda itunganijwe.
Sisitemu yo gushyushya no gukonjesha: Byakoreshejwe cyane mu kuvoma mu gushyushya, guhumeka, no guhumeka (HVAC).
Gutunganya amazi mabi: Kubijyanye no gutanga amazi mabi cyangwa amazi yatunganijwe.
Uburyo bwo kuhira: Imiyoboro y'amazi ikoreshwa mu kuhira ubutaka bw'ubuhinzi.
Ubucukuzi bw'amabuye y'agaciro: Ikoreshwa mu gutwara amazi na gaze mu birombe.
Ibicuruzwa Bifitanye isano
Kuva yashingwa mu 2014, Botop Steel yabaye iyambere mu gutanga imiyoboro ya karubone mu majyaruguru y’Ubushinwa, izwiho serivisi nziza, ibicuruzwa byiza, ndetse n’ibisubizo byuzuye.
Isosiyete itanga imiyoboro itandukanye ya karubone n'ibicuruzwa bifitanye isano,
harimo icyuma, ERW, LSAW, na SSAW umuyoboro wibyuma, hamwe numurongo wuzuye wibikoresho bya flanges na flanges.
Ibicuruzwa byayo bidasanzwe birimo kandi amavuta yo mu rwego rwo hejuru hamwe na austenitis ibyuma bitagira umuyonga, bigenewe guhuza ibyifuzo byimishinga itandukanye.
