Chitoliro Chachitsulo Chopanda Seam

Chitoliro chopanda chitsulondi pipepopanda msoko wowotcherera. Amapangidwa ndi kutenthetsa billet yolimba yachitsulo,kuboola kuti apange dzenje, kenaka ndikugudubuza ndi kukula kwa chubu ku OD yofunikira ndi makulidwe a khoma musanamalize (mankhwala otentha, kukonzekera komaliza, ndi kuyang'anitsitsa komaliza) ku mlingo wanu wotchulidwa ndi kalasi.

Octal Pipe imayang'ana kwambiri ntchito yamtunduwu. Timapereka chitoliro chachitsulo chosasinthika mumitundu yosiyanasiyana yamayiko -API 5L mzere chitoliro, ASTM A106 / A53 kwa ndondomeko mapaipi,A179/ A213 ya boiler ndi kutentha-machubu osinthanitsa, A335 ya aloyi yotentha-ntchito yotentha kwambiri, ndi EN 10216 ndi magiredi ogwirizana ndi GB/T. Mawindo owoneka bwino amaphimba10.3-1422 mm ODndi makulidwe a khoma mpaka150 mm, kotero kuti mizere yotumizira, machubu otenthetsera, mabalu osinthanitsa ndi mamembala amagulu onse atha kuchotsedwapulogalamu imodzi yogwirizana yopanda msokom'malo mogawanika pazigayo zingapo.

Kumbuyo kwa kukula ndi kalasi iliyonse kuli koyendetsedwanjira yopanga: mandrel- kapena pulagi-kugudubuza mphero, kutentha komwe kumatanthawuza, macheke athunthu ndi NDT / hydrotest scope. Gulu lililonse limatulutsidwa ndiEN 10204 3.1 kapena 3.2 satifiketi ndi kutentha kwathunthu, kupatsa akatswiri opanga mapulojekiti, QA ndi{0}}oyang'anira gulu lachitatu njira yowunikira bwino ndikuchepetsa chiopsezo cha-kukonzanso kwa mphindi zomaliza kapena kuyimitsa-zowonjezera pakavomerezedwa komaliza.

Mizere yosiyana imafuna chitoliro chosiyana - koma mafunso ambiri amafika ndi zosakwanira kapena zosakanikirana. Imodzi mwa njira zomwe Octal Pipe imawonjezera mtengo ndikuthandizira ogulagwirizanitsani muyeso woyenera ndi kalasi ku zochitika zenizeni zogwirira ntchito.

M'malo mwake, zambiri zamapulojekiti athu zimagwera m'magulu angapo:

• Mapaipi otumizira mafuta ndi gasi- kawirikawiriAPI 5L chitoliro chopanda msoko, B mpaka X70, PSL1 kapena PSL2 kutengera kapangidwe kamangidwe ndi kulimba amafuna. Timagwirizanitsa kulimba, DWTT (ngati zingafunike), kuyesa kwa CVN ndi njira zowawa kwambiri-zosankha ndi ma code pipeline design.
• Kutentha-kwambiri ndi mizere yowotchera – Chithunzi cha ASTM A106 / A335chitoliro chosasunthika mu magiredi a kaboni ndi aloyi (monga Gr.B, P11, P22, P91) pazomera zamagetsi, zoyeretsera ndi mayunitsi a petrochemical, okhala ndi chithandizo chowongolera kutentha ndi kuuma.
• Boiler ndi kutentha{0}}machubu osinthanitsa – ASTM A179/A192/A213ndi magiredi a EN 10216 ofanana ndi -machubu achitsulo a carbon ndi alloy, okhala ndi khoma lolimba komanso okulitsidwa / U{2}}chilolezo chopindika pakufunika.
• Kutentha-kocheperako komanso ntchito za cryogenic – ASTM A333 / EN 10216-4chitoliro chosasunthika choyesa mphamvu pa kutentha komwe kwatchulidwa-ziro, komwe kumagwiritsidwa ntchito posungira-kutsika pang'ono, LNG ndi kuzizira-mizere yantchito.
• Mapulogalamu a utumiki wowawasa- zipangizo ndi kuuma kulamulidwa kukumanaNACE MR0175 / ISO 15156kumene H₂S ilipo, kupeŵa zovuta ndi zoyenerera m'madera owawa.

Mukatitumizira deta yanu yofunikira (yapakati, kuthamanga, kutentha, kapangidwe kanu ndi zina zilizonse zowawasa / zotsika-zofuna kutentha), timaziyikamilingo yeniyeni, magiredi ndi zofunikira zoyesa, ndi kubweza mndandanda wa zinthu zoyera. Izi zimathandiza gulu lanu lamkati ndi alangizi kuwunika ndikuvomereza zomwe zafotokozedwa mwachangu, ndikuwonetsetsa kuti chitoliro chilichonse chopanda msoko chomwe timapereka ndi choyenera kugwira ntchito yomwe iyenera kugwira.

Kwa machubu otenthetsera ndi-paipi yamphamvu yosasokonekera, ogula samasamala za kuchuluka kwa makina omwe mphero ili nayo komanso zambiri zazomwe makinawa amatsimikizira pochita- ukhondo wa chitsulo, miyeso yokhazikika ndi zotsatira zoyesa zomwe zimadutsa ma boiler ndi kuthamanga-kuwunika kwa zombo. Octal Pipe sakhala ndi msoko amapangidwa pa sungunuka-ku-chubu njira ndi cholinga chimenecho.

Kuchokera Kupanga Zitsulo mpaka Kumaliza Tube - Zida Zofunika Kwambiri ndi Zomwe Zikutanthauza kwa Inu

Chifukwa mayunitsi awa amayendetsedwa ngatimzere umodzi wophatikizika, mumalandira machubu opanda msoko pomwe:

• ukhondo wachitsulo ndi chemistryzimayendetsedwa kuchokera kusungunuka, osati kufufuzidwa pa chubu yomalizidwa;
• khoma makulidwe, OD ndi kuwongokandi zotsatira za njira yoboola modzipereka ndi mandrel-pamphero, osati kusintha mwachisawawa;
• UT / eddy-mayeso apano ndi a labuzili kale m'malo opangira ma boiler, petrochemical ndi magetsi-ziyerekezo zamafakitale, kotero kuwunika kwanu{1}}ndi gulu lachitatu ndi kuvomereza ma code kumadutsa modabwitsa.

Kwa inu monga wogula, mtengo waukulu wa zida za Octal Pipe ndizosavuta:machubu opanda msoko omwe amakwaniritsa zojambula ndi ma code nthawi yoyamba, ndi njira yoyesera yomwe gulu lanu la QA ndi oyang'anira angadalire.

Chitoliro chachitsulo chosasokonezeka chimapangidwa poboola chigoba cholimba m'chigoba, kenako n'kutentha-kugudubuzika/kutalikirana mpaka kukula, kutsatiridwa ndi kukula/kuwongola ndi kuthira kutentha ngati kuli kofunikira.

Ogula akamayang'ana tchati choyendera chitoliro chopanda msoko, chofunikira kwambiri si kuchuluka kwa mabokosi omwe alipo, komakumene khalidwe latsekedwa ndikulembedwa. Octal Pipe imapanga mzere wake wopangira mandrel-chigayo mozungulira lingalirolo - chinsinsi chilichonse chimakhala ndi malo owongolera omwe atha kuwonedwa pambuyo pake mu MTC ndi malipoti oyendera.

1. Kudula billet, kutentha ndi kuboola - kuyambira chitsulo chomveka
Ma chubu osankhidwa amadulidwa kuti azitalikirana, -amafufuzidwa kenako n'kutenthedwa mu ng'anjo yozungulira yomwe imasinthasintha kutentha. Pokhapokha pamene chemistry ndi mawonekedwe a pamwamba atsimikiziridwa m'pamene amalowa mu mphero yoboola. Izi zimachepetsa chiwopsezo cha ma lamination ndikuwonetsetsa kuti chipolopolo chomwe timabowola ndichokwanira kale{3}}kuthamanga kwambiri.

2. Mandrel mphero kugudubuza, kutambasula kuchepetsa ndi kukula - kulamulira khoma ndi ovality
Chipolopolocho chimakulungidwa pa mphero ya mandrel kenako nkudutsamo-zoyimitsira zochepetsera/zoyesa. Pa nthawiyi timawunikaOD, makulidwe a khoma ndi eccentricityosati "kupanga chitoliro". Kusunga mfundozi m'zogwirizana ndi zomwe mwagwirizana ndizomwe zimalola kuti kupindika, kuwotcherera ndi AUT kuzitha kuyenda bwino popanda kudulidwa{1}}zowonjezera.

3. Kutentha mankhwala ndi zolemba ng'anjo zokhotakhota
Kutengera kalasi, mapaipi amasinthidwa kapena kuzimitsidwa ndikutenthedwa m'ng'anjo zopitilira kapena zamagulu. Nthawi ndi kutentha zimajambulidwa pa katundu aliyense, kotero mukawona makina amakina ndi kulimba kwa MTC, zimathandizidwa ndi kutentha kwenikweni-kupindika kwamankhwala. Izi ndizofunikira pama projekiti omwe akugwira ntchito ku API 5L, ASTM A106/A335 kapena EN 10216 pomwe malire olimba ndi kuuma amawunikidwa mosamalitsa.

4. Kuwongoka, kuyeretsa pamwamba ndi kuyang'ana mawonekedwe
Pambuyo pozizira, mapaipi amawongoledwa ndikuchotsedwa, ndiye OD, makulidwe a khoma ndi kutalika kwake zimayesedwanso. Machekewa amawonetsetsa kuti chitolirocho chikugwirizana ndi zojambulazo - osati pang'onopang'ono, koma chidutswa ndi chidutswa - kotero kuti ogulitsa zinthu ndi ogwira nawo ntchito amawononga nthawi yocheperako ndikusintha-ku-zinthu zolekerera.

5. NDT ndi kuyesa kwa hydrostatic - kuyang'ana zomwe simungathe kuziwona
Gawo lililonse lopanga limadutsaMagnetic flux leak ndi kuyesa kwa ultrasonic, ndi malekezero chitoliro Komanso kufufuzidwa ndi maginito tinthu anayendera. Zowonongeka zimachotsedwa kapena chitoliro chimakanidwa chisanafike kuyezetsa kwa hydrostatic. Panthawi ya hydrotest, chitoliro chilichonse chimakhala choponderezedwa ndikugwiritsiridwa ntchito kukakamiza kwa mayeso omwe atchulidwa, kupereka umboni wolembedwa kuti akhoza kupirira kukakamizidwa kwa mzere wanu.

6. Kuyeza, kupaka, kuika chizindikiro ndi kulongedza - kupanga kukonzekera polojekiti yanu
Pomaliza, mapaipi amapimidwa ndi kuyeza, kenaka n’kupopera-penti kapena kumatidwa monga mwanenera ndi kuikidwa zipewa. Utali uliwonse umakhala ndi mzere wodziwika bwino (kukula, giredi, muyezo, nambala ya kutentha), mitolo imayikidwa, ndipo mindandanda yolongedza imafanana ndi zikalata zoyendera. Izi zimalola eni ake, ma EPC ndi oyang'anira gulu lachitatu{3}}kufufuza chitoliro chilichonse patsamba kuti chibwerere ku zotsatira zake zoyeserera popanda kuyerekezera.

Kodi Octal Pipe angapereke kukula kwake ndi kalasi yanji kwa chitoliro chachitsulo chosasunthika?

Timapereka chitoliro chopanda msoko kuchokera ku 10.3-1422 mm OD ndi makulidwe a khoma mpaka 150 mm mu API 5L, ASTM A106/A53, A179, A213, A335 ndi EN 10216 giredi.

Kodi mapaipi anu opanda msoko angakwanitse pulojekiti yokhazikika komanso zofunikira zowunika-zipani zachitatu?

Inde. Gulu lililonse limabwera ndi EN 10204 3.1 / 3.2 MTCs, NDT yodziwika bwino komanso malipoti a hydrotest komanso kuwunika kokwanira kuti zithandizire pulojekiti ndi zowunikira-zipani zina.
