1. Kodi mapaipi achitsulo alibe)
Mapaipi opanda pake a carbon mapipe amapangidwa kuchokera pachidutswa chimodzi popanda mafupa obiriwira, kupereka mphamvu yayikulu komanso kukana mphamvu.
Mapaipi awa amagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana chifukwa chazinthu zabwino kwambiri. Mapaipi achitsulo osawoneka a carbon amadziwika chifukwa chodalirika komanso kudalirika. Amatha kupirira zovuta zambiri komanso kutentha, kumawapangitsa kukhala oyenera pantchito mu mafakitale ndi mafuta, mbadwo wamagetsi, ndi mankhwala.
Makina opanga mikangano yosoka carbon imaphatikizapo kujambula kotentha kapena kuzizira. Poyendetsa otentha, billet ya chitsulo imatenthedwa ndikudutsa mndandanda wambiri kuti apange chitoliro chopanda chosakira. Kujambula kozizira, kumbali ina, kumaphatikizapo kukoka chitoliro chotentha kudzera mu dia kuti muchepetse mainchesi ake ndikusintha pansi.
Malinga ndi deta yamakampani, mapaipi achitsulo a carbon amapezeka m'mitundu yambiri ndi makulidwe osiyanasiyana. Makulidwe ofala kwambiri ochokera kwa DN15 mpaka DN1200, wokhala ndi khoma limasiyana ndi 2mm mpaka 50mm. Zinthu zomwe zimagwiritsidwa ntchito pazithunzi zazitsulo zosawoneka bwino zimakhala zachitsulo, zomwe zimakhala ndi gawo lina la kaboni. Zokhala ndi kaboni zimatha kukhala zosiyanasiyana kutengera zomwe mukufuna, zomwe zimakhala ndi mphamvu zambiri za kaboni ndi kuuma.
Kuphatikiza pa mphamvu ndi kukhazikika, mapaipi achitsulo amaperekanso kukana bwino. Komabe, pogwiritsa ntchito njira zina zomwe zimawonekera m'malo omwe akuyembekezeredwa, zowonjezera kapena zingwe zitha kuyenera kuteteza chitolirochi kuzipiririka.
Mapaipi onse osokoneza bongo ndi chinthu chofunikira kwambiri pamakampani ambiri, amapereka malo odalirika komanso othandiza madzi ndi mpweya.
2. Kupanga ndondomeko ndi zochitika
2.1 kupanga mawonekedwe mwachidule
Kupanga mapaipi achitsulo opanda kanthu ndi njira yovuta komanso yodziwikiratu. Choyamba, ma billet ozungulira amadula moyenera kutalika. Kenako, imawotchera mu ng'anjo yotentha kwambiri, makamaka pafupifupi 1200 digiri Celsius. Njira yotentha imagwiritsa ntchito mafuta ngati haidrogen kapena acetylene kuti awonetsetse kulumikizidwa. Pambuyo potenthetsa, billet imayenda pang'onopang'ono. Izi nthawi zambiri zimachitika pogwiritsa ntchito a锥形辊穿孔机zomwe zimathandiza kupanga mapaipi apamwamba kwambiri ndipo imatha kuzolowera zofuna za magiredi osiyanasiyana.
Pambuyo poboola, billelet imadutsa njira zogulira monga kusunthira kwa magawo atatu, kusunthika mosalekeza, kapena kutulutsidwa. Pambuyo popepuka, chitoliro chomwe chimachitika ndikuchirikiza kuti udziwe kukula kwake komaliza. Makina ogwiritsira ntchito ndi kubowola pang'ono amazungulira liwiro lalitali ndikulowa ma billet kuti apange chitoliro. Umodzi wamkati wa chitoliro umatengera m'mimba mwakunja kwa makina ochita malonda.
Kenako, chitolirocho chimatumizidwa ku nsanja yozizira pomwe umakhazikika ndi madzi othira utsi. Pambuyo pozizira, zimawongola kuti mawonekedwe ake ndi olondola. Kenako, chitolirocho chimatumizidwa ku chotchinga chachitsulo kapena chida cha hydrostatic cha kuyendera mkati. Ngati pali ming'alu, thovu, kapena zovuta zina mkati mwa chitolirocho, adzapezeka. Pambuyo poyendera, chitoliro chimadutsa pamakina. Pomaliza, ili ndi manambala, zojambula, ndi chidziwitso cha batch chojambulidwa ndipo chimakwezedwa ndikusungidwa mnyumba yosungiramo katundu.
2.2 zokhudzana ndi gulu
Mapaipi achitsulo osawoneka a carbon amatchulidwa m'magulu owotchera otentha komanso ozizira. Mapaipi achitsulo osawoneka bwino nthawi zambiri amakhala ndi mainchesi opitilira 32 ndi khoma makulidwe ochokera kwa 25 mpaka 75. Mapaipi ozizira osakhala osalala amatha kukhala ndi mainchesi akunja ngati mamilimita 6, omwe ali ndi millimeter ya mamilimita 0,25. Ngakhale mapaipi ocheperako okhala ndi mainchesi akunja a mamilimita 5 ndi khoma makulidwe ochepera 0,25 mamilimita. Mapaipi ozizira amapatulidwa molondola.
Zogwirizana zawo nthawi zambiri zimafotokozedwa mogwirizana ndi mainchesi apanja akunja ndi makulidwe a khoma. Mwachitsanzo, lingaliro wamba lingakhale DN200 x 6mm, kuwonetsa m'mimba mwa milimerate 200 ndi khoma makulidwe a mamilimita 6. Malinga ndi deta yamakampani, mapaipi achitsulo amapezeka m'mitundu yambiri kuti akakwaniritse zofunika kugwiritsa ntchito.
3. Kugwiritsa ntchito mapaipi achitsulo opanda kanthu
Mapapu osawoneka a carbon a carbon amapeza ntchito m'minda yosiyanasiyana monga mayendedwe amadzimadzi, kupanga ma bolailogical, kufufuza kwa ma pelogical, ndi makampani opanga zinthu zina mwazinthu zapadera.
3.1 Kuyendetsa Madzimadzi
Mapaipi achitsulo osawoneka bwino amagwiritsidwa ntchito kwambiri ponyamula zakumadzi monga madzi, mafuta, ndi mpweya. M'mafuta a mafuta ndi gasi, mwachitsanzo, mapaipi achitsulo osawoneka bwino ndiofunika kunyamula mafuta osawoneka bwino ndi mpweya wachilengedwe kuchokera m'malo opangira mapangidwe ndi malo ogulitsira. Malinga ndi deta yamakampani, gawo lalikulu la mafuta ndi mafuta padziko lapansi limayendetsedwa kudzera pamapaipi achitsulo opanda nyama. Mapaipi awa amatha kupirira zovuta zapamwamba ndipo amalimbana ndi kutukuka, kuwapangitsa kukhala abwino kuyenda kwa nthawi yayitali. Kuphatikiza apo, mapaipi achitsulo osoka amagwiritsidwanso ntchito m'madzi ndi mafakitale amafakitale onyamula zakumwa zosiyanasiyana.
3.2 kupanga
Mapaipi ochepa, apakatikati, komanso okwera kwambiri opangidwa ndi mikangano yopanda misaboni ndi zigawo zokhudzana ndi kaboni. Mapaipi awa amapangidwa kuti apirire kutentha kwambiri komanso kupsinjika mkati mwa ma boiler. Pamiyala yotsika komanso yosavuta kupanikizika, mapaipi osawoneka bwino amawonetsetsa kuti amayendetsa bwino ma boiler popereka madzi osungunuka ndi kutentha. M'malo opanikizika kwambiri, mapaipi ayenera kukumana ndi zikhalidwe zothandizira kulimba ndi kukhazikika. Amayesedwa kwambiri kuti atsimikizire kuti ndi odalirika komanso odalirika. Mapaipi opanda pake a casiler amapezeka mumitundu yambiri ndi zojambula zosiyanasiyana kuti akwaniritse zosowa zenizeni za zojambula zosiyanasiyana za boleler.
3.3 Kufufuza Kwadziko
Mapaipi a geological ndi mafuta obowola amatenga gawo lofunikira pakufufuza za ku Geologication. Mapaipi awa amagwiritsidwa ntchito pobowola kutumphuka kwadziko lapansi kuti akafufuze mafuta, mpweya, ndi mchere. Mapaipi apamwamba kwambiri osakhazikika a carbon amapangidwira kuti athe kupirira malo ovuta azobowola, kuphatikizapo kupsinjika kwambiri, abrasion, ndi kututa. Amagwiritsidwanso ntchito pochotsa ndi tubeni zitsime zamafuta ndi ma gasi, ndikuthandizira pakuwongolera ndikuteteza bwino. Malinga ndi mafakitale ogulitsa, kufunikira kwa mapaipi a geologican ndi mafuta kumayembekezeredwa kukulira m'zaka zikubwerazi monga momwe akupezera ndalama zatsopano zikupitirirabe.
3.4 Makampani Opanga Mafuta
M'makampani a petroleum, mapaipi achitsulo amagwiritsidwa ntchito pamapulogalamu osiyanasiyana monga mafuta ndi mafuta m'mapaipi a mafuta, kukonza zida, ndi akasinja osungira. Mapaipi amapangidwa kuti azitha kupirira malo okhala mafuta a mankhwala a petroleum komanso zovuta zambiri zomwe zimakhudzidwa ndi mayendedwe ndikukonzekera. Mapaipi osokoneza petroleum, makamaka, ndi ofunikira pakuyenga. Amapangidwa kuchokera ku zitsulo zapadera zomwe zimatha kupirira kutentha kwambiri ndi zomwe zimachitika. Mapaipi opanda pake a carbon mu makampani ogulitsa matenda a petroleamu amatengera kuwongolera kokhazikika ndikuyesa kuonetsetsa chitetezo chawo komanso kudalirika.
