ZOFUNIKA KWAMBIRI
- Ufa wothira mafuta a thermit wogwiritsidwa ntchito pa mapaipi ndi wosakaniza wa mkuwa ndi aluminiyamu, ndipo uyenera kusakanizidwa ndi zinthu ndi kukula kwa kondakitala wanu - kusakaniza kwapadera kumapanga malo olumikizirana ofooka komanso olimba.
- Chikombole cha graphite chabwino chimapereka malo olumikizirana 80–100 musanachisinthe, kotero kuchuluka kwa nkhungu — osati kuchuluka kwa ufa — nthawi zambiri kumayendetsa nthawi yanu yoyitanitsanso.

Kuchokera ku Arc Strikes kupita ku Molecular Bonds: Nchifukwa chiyani Ogwira Ntchito a CP Amanenabe za Kuweta kwa Pipeline Thermit?
Yankho lalifupi: chifukwa dongosolo loteteza cathodic (CP) — kugwiritsa ntchito kwapadera kwa ma anode amagetsi olunjika kapena odzipereka kuti agwire payipi yachitsulo yobisika pamalo pomwe dzimbiri limakhala losafunikira — ndi lodalirika kokha ngati kulumikizana kwake.Popeza chingwe chilichonse choyesera, chingwe cha anode ndi waya wa bond ziyenera kukhalabe zamagetsi nthawi zonse pakupanga mapaipi, akatswiri amasankha chomangira cha molekyulu m'malo mwa chamakina.Kuweta kwa exothermic, komwe kumalembedwanso kuti thermit welding ndipo kumadziwika m'munda ndi mawu oti CAD weld (kuchokera ku mtundu wa Cadweld), kumalumikiza kondakitala pamwamba pa chitoliro mu nkhungu ya graphite pogwiritsa ntchito mkuwa wosungunuka wopangidwa ndi ufa. Palibe chomangirira choti chimasulire, palibe cholumikizira cholimba kuti chikwere, ndipo palibe arc strike pakhoma la chitoliro.
Ndakhala ndikuonera izi kuchokera kumbali ya zinthu zoperekera kwa zaka khumi ndi ziwiri. Pamene kontrakitala wa mapaipi asintha kuchoka pa ma clamp amakina kupita ku ma exothermic connections, oda yoyamba yogulira nthawi zambiri imakhala yaying'ono komanso yosamala - gulu limodzi, limodzi lofalikira. Oda yachiwiri imakhala yayikulu.Popeza chotchingira sichifuna jenereta, makina ochizira komanso chotchingira chovomerezeka m'ngalande, ogwira ntchito amasunga mitengo yopangira ngakhale m'malo akutali komwe kunyamula zida zochizira arc-welding sikungatheke.Zolemba za fakitale yathu zimanena momveka bwino kuti njira imeneyi ndi yotsika mtengo, yonyamulika, komanso yosavuta kugwiritsa ntchito popanda luso lapadera. Sichilankhulo chotsatsa malonda; ndichifukwa chake njira imeneyi yasintha maulumikizidwe amakina kudzera mu grounding ndi CP m'zaka makumi awiri zapitazi.
Zipangizo Zowotcherera Zoteteza Cathodic: Kodi kwenikweni ndi chiyani mkati mwa BOM ya Kontrakitala?
Zinthu zonse zolumikizirana ndi exothermic CP zili ndi zinthu zambiri kuposa zomwe ogula ambiri amayembekezera. Pa malo athu opangira zinthu, ndimatha kuwona zinthu zokonzeka kutumiza zikugwirizana:ufa wowotcherera wa thermityokha, nkhungu ya graphite yomwe imapanga cholumikizira, mfuti yoyatsira moto ya mwala wa flint, diski yachitsulo yomwe imatseka chipinda cha ufa mpaka chiyambe kuyambika, chomangira chomangira, magolovesi osatentha, ndi maburashi oyeretsera. Osasowa chimodzi mwa izi ndipo gulu lanu likuchita zinthu zatsopano pa ngalande.
Zinthu zitatu ziyenera kuganiziridwa ndi wogula chifukwa zimatsimikiza ubwino wa cholumikizira:
- Ufa wothira mafuta a thermit.Ufa wathu wothira mafuta opangidwa ndi exothermic ndi wosakaniza wa copper oxide ndi aluminiyamu — izi zimachepetsa copper oxide kukhala copper wosungunuka pa kutentha kokwanira kuti zigwirizane ndi ma conductor a copper ku chitsulo. Chofunika kwambiri ndi kupeza chiŵerengero: timasakaniza ufawo kuti ugwirizane ndi zinthu za conductor wanu ndi gawo lake,Chifukwa chaja yochepa kwambiri imasiya cholumikizira chosakwanira pomwe chachikulu kwambiri chimachotsa chitsulo mu nkhungu ndikutaya zinthu zonse pa cholumikizira chilichonse..
- Kutulutsa kwa thermitndi zinthu zoyambira.Kutuluka kwa madzi kumasunga madziwo kukhala oyera ndipo kumathandiza mkuwa wosungunuka kunyowetsa pamwamba pa chitoliro; m'mawa wonyowa kapena chitsulo chosatsukidwa bwino, kutuluka kwa madziko ndi komwe kumateteza cholumikiziracho ku maenje obowoka.
- Chifaniziro cha graphite.Ichi ndi gawo lolondola. Chiboliboli cha graphite chopangidwa bwino chimatseka mwamphamvu mozungulira kondakitala ndi chitoliro, ndipo zolemba zathu za fakitale zimasonyeza moyo wautumiki wa maulumikizidwe 80–100 pa chiboliboli chilichonse — nthawi yayitali kuposa ziboliboli zambiri zomwe makasitomala athu adaziyerekeza nazo. Chiboliboli chotha ntchito chimataya mkuwa wosungunuka, ndipo chiboliboli chotuluka chimapanga chiboliboli chomwe woyang'anira wanu angakane.

Pa kufalikira kwa pompopompo, choletsa sichimakhala chotchingira chokha - ndi gulu lophimba kumbuyo kwanu. Kulumikizana kwa exothermic kumatenga mphindi zochepa: kutsuka pamwamba pa chitoliro ndi kondakitala kukhala chitsulo chowala, kuyika chikombole, kugwetsa chitsulocho mu diski, kuyika ufa, kuyatsa ndi mfuti ya flint, kudikira kuti chichitike, kuswa chikombole, ndikutsuka cholumikizira cha chogwiritsira ntchito chophimba. Tinajambula chithunzi chathu cha masitepe asanu ndi atatu pa malo enieni, ndipo chimayambira kukonzekera pamwamba mpaka kulumikizana komalizidwa, kokonzeka kuwunika.

FAQ
Kodi kuwotcherera kwa exothermic kumavomerezedwa polumikizira chitetezo cha cathodic pamapaipi?
Inde. Kuwotcherera kwa exothermic (thermit) ndi njira yodziwika bwino yolumikizira ma test leads, ma anode cables ndi ma bond wards ku mapaipi obisika chifukwa amapanga ma molecular bond osatha popanda gwero lamagetsi lakunja. Zofunikira pa dongosolo la CP zili pansi pa AMPP/NACE SP0169 ndipo, pa mizere yakunja, ISO 15589-2:2024; kukhazikika kwa kulumikizana nthawi zambiri kumayesedwa motsutsana ndi IEEE 837.
Kodi pali kusiyana kotani pakati pa ufa wothira thermit ndi flux wothira thermit?
Ufa ndi mphamvu ya reactant — chisakanizo cha copper oxide ndi aluminiyamu chomwe chimapanga mkuwa wosungunuka pa cholumikizira. Kutulukako kumathandizira kuyankha mwa kuyeretsa ndi kunyowetsa pamwamba kuti mkuwa ugwirizane popanda kubowola. Zonsezi zimagwiritsidwa ntchito kamodzi pa cholumikizira chilichonse, ndipo zonse ziyenera kufanana ndi chipangizo cha kondakitala ndi kukula komwe mukulumikiza.
Kodi nkhungu imodzi ya graphite imatha kusungunula zingati?
Nthawi yathu yogwirira ntchito yolembedwa ndi fakitale ndi 80–100 zolumikizira zolumikizira pa nkhungu iliyonse, poganizira kusungidwa kouma ndi kuigwira mosamala. Nkhungu zomwe zimasweka kapena kutuluka msanga nthawi zambiri zimakhala chizindikiro cha graphite yotsika, kuigwira molakwika, kapena kukhudzidwa ndi chinyezi - ndipo nkhungu iliyonse yolephera imawononganso mphamvu ya ufa ndi nthawi yogwirira ntchito pa nkhunguyo.
Kodi "CAD weld" imatanthauza chinthu chomwecho ndi exothermic welding?
Mu ntchito yamunda, inde. "CAD weld" imachokera ku dzina la kampani ya Cadweld ndipo yakhala dzina lodziwika bwino la malo ogwirira ntchito la exothermic kapena thermit welding. Mukalemba RFQ, tchulani njira yodziwika bwino, zipangizo ndi kukula kwa conductor, ndi miyezo yoyenera m'malo mwa dzina lililonse la kampani - lomwe limapangitsa kuti mitengo ikhale yofanana.
Kodi RFQ ya zipangizo zotetezera za cathodic iyenera kukhala ndi chiyani?
Phatikizani zinthu zoyendetsera ndi gawo lopingasa, mawonekedwe a pamwamba pa chitoliro (chathyathyathya, chopindika, m'mimba mwake), mtundu wa zolumikizira, kuchuluka kwa zolumikizira zonse, miyezo yoyenera (AMPP SP0169, ISO 15589-2, IEEE 837 monga momwe zilili), zofunikira pakulongedza ndi polowera, komanso ngati mukufuna zida zonse. Deta ya woyendetsa ikakhala yolondola kwambiri, ufawo ukhoza kusakanizidwa molondola.
Kodi ufa wothira mafuta ophikira umapakidwa bwanji kuti utumizidwe kunja, ndipo umachokera ku madoko ati?
Kulongedza kwathu kokhazikika kwa katundu wotumizidwa kunja ndi zidutswa 10 pa bokosi lililonse ndi mabokosi 10 pa bokosi lililonse, ndi mabotolo otsekedwa kuti asanyowe ndi chinyezi ndi nkhungu mkati mwa bokosilo. Kutumiza kumachokera ku Ningbo kapena Shanghai, ndipo mphamvu yathu yoperekera katundu m'fakitale ndi zidutswa 100,000 pamwezi, zomwe zimakwaniritsa maoda a polojekiti popanda kugawa magawo osiyanasiyana.
Mukufuna kupeza ufa wothira thermit, ma mold kapena flux ya pulojekiti ya CP ya pipeline? Titumizireni ma specs anu a conductor ndi chiwerengero cha ma joint — tidzakubwezerani fomula yofanana, ndandanda yogwiritsidwa ntchito komanso tsatanetsatane wa zikalata zotumizira kunja.
