Umuyoboro w'icyuma

Umuyoboro w'icyumani ruswa - irwanya ibyuma bya tubular ibicuruzwa byakozwe hafiitangazamakuru rya serivisi, urwego rwa chloride, ubushyuhe, igitutu, nuburyo bwo guhimba(gusudira, kunama, gutora / passivation). Umuyoboro "iburyo" ntabwo watoranijwe mwizina ryonyine - abaguzi mubisanzwe bafungabisanzwe (ASTM / EN / ISO), ifishi y'ibicuruzwa (idafite kashe cyangwa isudira), hamwe n'ubugenzuzi / inyandikoubanza, hanyuma wemeze urwego nubuso bukenewe mugihe kirekire - igihe cyo kwizerwa.

Umuyoboro w'icyuma ni kimwe mu bikoreshwa cyane mu gusohora imiyoboro ivangwa n'amazi yangirika, serivise yo hejuru -, hamwe n'ubushyuhe bwo hejuru. Mu rwego mpuzamahanga ruzwi na ASTM A312 / ASME SA312, imiyoboro y'ibyuma idafite ingese ikorwa mu buryo budasubirwaho, bwo gusudira, no gukonja cyane - kugira ngo byuzuze ibisabwa cyane mu nganda nka peteroli na gaze, peteroli, peteroli, amashanyarazi, gutunganya amazi, ibiryo n'ibinyobwa, n'ubwubatsi.

Nka auruganda rukora ibyumano kohereza hanze - yerekanwe gutanga isoko muriUmuyoboro w'icyuma Ubushinwa, Umuyoboro wa Octal utanga imiyoboro idafite ibyuma idafite ibipimo byuzuye, igenzura ryuzuye, hamwe nubwishingizi bukomeye. Ibicuruzwa byacu byemejwe ku rwego mpuzamahanga mpuzamahanga (ASTM, ASME, EN, DIN) kandi byujuje ibisabwa kugira ngo byuzuze ibyifuzo by’abakiriya muri sisitemu zikomeye ndetse no mu miterere.

Umuyoboro wa Octal utanga imiyoboro yicyuma idafite ingese yakozwe hubahirijwe ASTM A312 / ASME SA312 nibindi bipimo mpuzamahanga. Iyi miyoboro iraboneka muburyo butagira ikizinga, gusudira (ERW / EFW), hamwe nimbeho ikonje cyane (HCW), itanga imbaraga zo kurwanya ruswa, imbaraga zubushyuhe bwo hejuru, hamwe nuburinganire bwuzuye.
Hamwe n'amanota akubiyemo TP304 / 304L, TP316 / 316L, TP321, TP347, TP310S, Duplex 2205, na Super Duplex 2507, imiyoboro yacu idafite ibyuma ikora inganda zitandukanye zirimo peteroli na gaze, peteroli, inganda, gutunganya imiti, kubyara amazi, ibiryo n'ibinyobwa, n'ubwubatsi.

1.Scope & Base Ibipimo

• ASTM A312 / ASME SA312 - Umuyoboro wa Austenitike udafite ibyuma byo kwangirika muri rusange na - serivisi yubushyuhe; itwikiriye Seamless (SMLS), Yasuditswe (hamwe / utuzuza), hamwe n'ubukonje bukabije (HCW).

316L Umuyoboro w'icyuma

316L umuyoboro w'icyumaisobanurwa kenshi kuri chloride - itwara amazi, serivisi zoroheje z’imiti, hamwe n’ibikoresho byo mu nyanja - kubera ko imiti ya Mo - itunganya imiti igabanya ubukana bwa 304 / 304L, mu gihe icyiciro cya "L" gishyigikira ibihimbano bitekanye mu kugabanya ingaruka zo gukangurira abantu gusudira.

Mu gutanga amasoko,316L umuyoboro w'icyumabigomba gusobanurwa na:.

Umuyoboro wibyuma bitangwa muri rusange nkukonta nkomyicyangwagusudira, kandi guhitamo kwiza kugenwa nainshingano (igitutu / ubushyuhe / gupakira cyclic), uburyo bwo guhimba, n'ubugenzuzi busabwa n'umushinga ITP. Mu gutanga amasoko, "seamless vs welded" ntabwo ari bike mubyifuzo ndetse no kumenya niba serivisi yemerera ikidodo - nuburyo ubwo buryo buzemerwa kandi bukandikwa. Nubusanzwe uburyo Octal Umuyoboro uhitamo guhitamo mugihe uvuze ivanze - ingano yububiko.

Umuyoboro w'icyuma udafite ingeseni Byahiswemo Iyo Inshingano Zikomeye - umuvuduko mwinshi, ubushyuhe bwo hejuru, cyangwa byinshi bisaba gusiganwa ku magare yumuriro - kandi mugihe abaguzi bashaka umubiri wumuyoboro umwe kumurongo utoroshye. Ninzira kandi ifatika kuri diametero ntoya aho kuboneka bidasubirwaho gukomera no gusudira - isubiramo ryongeyeho ibintu bitari ngombwa mukwakira. Ibyingenzi byingenzi byatoranijwe birimo:

• Icyerekezo / kode isaba neza
• Hejuru - ubushyuhe cyangwa serivisi ya cycle aho igishushanyo mbonera gikunzwe
• Kwihanganirana gukwiranye - hejuru kubintu byateguwe

Umuyoboro w'icyuma usudira. Hano amasoko yibanze ahinduka mukwemera - kugenzura ibikorwa byo gusudira, urugero rwa NDT (UT / RT aho bibaye ngombwa), hamwe nibisabwa kumiterere (gutoranya / passivation) bigira ingaruka kumasuku yatangijwe. Kuri paki zasuditswe, Umuyoboro wa Octal mubisanzwe uhuza igipimo cyo kugenzura hamwe ninyandiko kumuhanda wemererwa kugirango umushinga wo gusohora ntugume mubisobanuro.

Ibipimo bisanzwe bikoreshwa mumishinga birimoASTM A312(umuyoboro wa austenitis utagira umuyonga),ASTM A790(duplex idafite umuyoboro),ASTM A213(boiler / ubushyuhe bwo guhinduranya ubushyuhe),ASTM A269(ibikoresho bya tubing), naASTM A358(nini - OD welded umuyoboro wa austenitis).

Niba usuzuma auruganda rukora ibyuma, mubyukuri gutandukanya inkomoko yizewe ningaruka ni uruganda - urwego rusubirwamo:Kugenzura amanota, ubunyangamugayo bwo gusudira (kumuyoboro wasudutse), guhagarara neza, imiterere yubuso, hamwe no gukurikiranwa. Nka auruganda rukora ibyuma- ushyigikiwe nuwitanga muriUmuyoboro w'icyuma Ubushinwa, Umuyoboro wa Octal washyizweho kugirango urekure umuyoboro udafite umwanda hamwe nubugenzuzi abaguzi bashobora kugenzura imishinga nyayo - cyane cyane kumapaki avanze - aho 304L na316L umuyoboro w'icyumantishobora kwemererwa kwambuka.

Uruganda rwacu - ingingo zo kugenzura kuruhande zirimo:

• Kugenzura PMI / chimie (mugihe bikenewe):irinda ikosa - kuvanga amanota - hejuru, ingaruka zisanzwe zo kwakira ibintu kumurongo wa 304L / 316L.
• Kugenzura ibipimo:OD / WT, ovality, kugororoka - ibi byemeza bikwiye - hejuru yihuta kubintu byabanjirije gukora no kwiruka birebire.
• Kugenzura ikidodo cyo gusudira (kumuyoboro wasudutse):Ku musaruro ukorwa nka 316L umuyoboro wibyuma, dufunga ibipimo byo gusudira (idirishya ryinjiza ubushyuhe, umuvuduko wurugendo, gukingira ikingira) kandi dukurikirana umutekano muke hamwe no gukurikirana umurongo -; umwirondoro wamasaro weld ugenzurwa kumushinga wemererwa (mubisanzwe bisobanurwa nkurugero rwuburebure bwamasaro / munsi yo guhuza no guhuza nkumurimo wubugari bwurukuta), kandi gutunganya amasaro imbere biracungwa aho bisabwa kugirango bore ihamye kubikorwa byo guhimba no gutemba.
• Imiterere yubuso:gutoranya / gutambuka no kugira isuku bisobanurwa kugirango wirinde "kugaragara neza, kunanirwa muri serivisi / gutangiza" gutungurwa.
• Kwohereza ibicuruzwa hanze & gusohora ikarita:KuriUmuyoboro w'icyuma Ubushinwagutanga, ibyago rusange byumushinga ni urwego ruvanze - hejuru, kwangirika kwubutaka, no gutinda kurekurwa. Umuyoboro wa Octal ugabanya ibi hamwe nibimenyetso bisobanutse, kurinda impera, guhitamo bundle / ikadiri yo gupakira, hamwe nibintu byinshi - bishingiye kubisohora ikaritaikimenyetso cyerekana imiyoboro → MTC records inyandiko zerekana ubugenzuzi. Igisubizo kiroroshye: ibisabwa bike, bike re - kugenzura inzinguzingo, no gusohora ububiko bwihuse - kubera ko umuyoboro ugera nka sisitemu igenzurwa, ntabwo ari ikirundo cyibikoresho.

Niyo mpamvu abaguzi benshi bashakishauruganda rukora ibyumacyangwauruganda rukora ibyumainUmuyoboro w'icyuma Ubushinwawitondere bike kubisabwa muri rusange nibindi byinshi niba uwabitanze ashobora guhora atanga ibisubizo bimwe: amanota meza (harimo316L umuyoboro w'icyuma), ibipimo byiza, ubuso bwiburyo, nibimenyetso byukuri byo kugenzura - nta rezo yo kwakira.

Nkumuhinguzi wibyuma bitagira umuyonga, Umuyoboro wa Octal urekura umuyoboro udafite umwanda ufite ibipimo byumusaruro ugenzurwa, ubuziranenge bwikigereranyo (aho bishoboka), hamwe nubushakashatsi bwakurikiranwe.

1.Seamless (SMLS)

• Inzira: Gushyushya bilet → Gutobora → Kuzunguruka → Ingano → Igisubizo Annealing → Gutoranya → Kwipimisha.
• Inyungu: Nta kashe yo gusudira, yizewe hejuru - igitutu na serivisi zikomeye.

2.Gusudira (ERW / EFW)

• Inzira: Kwandika cyangwa isahani ikora → Longitudinal / spiral welding → Igisubizo annealing → Ingano → Kugororoka.
• Uburyo bwo gusudira: ERW / HFI, TIG / GTAW, SAW, EFW bitewe na OD / WT.
• Inyungu: Igiciro - gikora neza, ubunini bwagutse burahari, amahitamo yisuku hamwe no gukuraho amasaro.

3.Ubukonje bukabije bwakoze (HCW)

• Inzira: Kugabanya ubukonje kumuyoboro usudutse + annealing.
• Inyungu: Kongera imbaraga, kwihanganira gukomera, kurangiza neza.

4.Ubushyuhe bwo kuvura & Ubuso

• Igisubizo Annealing: kuzimya dogere 1050–1150.
• Amahitamo yubuso: Yegeranye & yatoranijwe, yometse hejuru, satine - isize, indorerwamo - isize.

5. Kugenzura ubuziranenge

• Kwipimisha Hydrostatike, Eddy Ibiriho / UT, Radiografiya kumurongo hamwe numubiri.
• Igeragezwa rya mashini: Umujinya, umusaruro, gukomera, gusibanganya / gucana.
• Ibizamini byo kwangirika kubushake: ASTM A262 (IGC), ASTM G48 (piting).

Iyo umuguzi aturukaUmuyoboro w'icyuma Ubushinwa, ingaruka nyazo ntabwo "zishobora gukora urusyo" - ni ukumenya niba uwabitanze ashoborakomeza urwego + ubunini + imiterere y'ubusoburigihe murwego rwose. Porogaramu ya Octal Pipe idafite ibyuma byubatswe kuri uko kuri: imiyoboro idafite uburinganire bwa OD iringaniye kandi igenzurwa hejuru, hiyongereyeho umuyoboro usudira wa diametero nini, byose bisohoka mu ruganda ruhuza kuzunguruka / gushushanya, kuvura ubushyuhe, kugorora, no gutoragura kumurongo umwe.

Icyo ibi bivuze kuri PO nyayo biroroshye.
