Mu dziko lomwe likusintha nthawi zonse la ntchito zomanga ndi mafakitale, kufunikira kwa zipangizo zolimba komanso zodalirika ndikofunikira kwambiri. Pakati pa zipangizozi, mapaipi olumikizidwa kawiri, makamaka omwe akukwaniritsa miyezo ya ASTM A252, akhala maziko a ntchito zosiyanasiyana. Blog iyi ikufotokoza momwe mapaipi olumikizidwa kawiri amagwiritsidwira ntchito pomanga ndi mafakitale amakono, kuwonetsa kufunika kwawo ndi ubwino wawo.
Chitoliro cholumikizidwa kawiri, yomwe imadziwikanso kuti chitoliro cha DSAW (double submided arc welded), imatha kupirira kupsinjika kwakukulu ndipo ndi yoyenera malo osiyanasiyana ovuta. Muyezo wa ASTM A252 womwe umalamulira kupanga mapaipi awa wakhala wodalirika ndi mainjiniya ndi akatswiri omanga kwa zaka zambiri. Muyezowu umaonetsetsa kuti mapaipi akukwaniritsa miyezo yokhwima komanso magwiridwe antchito, zomwe zimapangitsa kuti akhale abwino kwambiri pa ntchito yomanga, mafuta ndi gasi, ndi ntchito zina zazikulu zamafakitale.
Chimodzi mwa ntchito zazikulu za mapaipi olumikizidwa kawiri ndi kupanga mafelemu omangira. Chifukwa cha mphamvu ndi kulimba komwe kumafunika kuti zithandizire katundu wolemera, mapaipi awa ndi ofunikira kwambiri pomanga milatho, nyumba, ndi mapulojekiti ena omanga. Kutha kwawo kupirira kupsinjika kwakukulu kumawapangitsanso kukhala oyenera kugwiritsidwa ntchito pomanga mipanda, komwe amaponyedwa pansi kuti apereke maziko.
Mu makampani opanga mafuta ndi gasi,Mapaipi a DSAWimagwira ntchito yofunika kwambiri poyendetsa madzi ndi mpweya. Kapangidwe kake kolimba kamathandiza kuti ipirire kupsinjika kwakukulu komwe kumakhudzana ndi zinthuzi, kuonetsetsa kuti mayendedwe ake ndi otetezeka komanso ogwira mtima. Kuphatikiza apo, kukana dzimbiri kwa chitoliro cha DSAW kumapangitsa kuti chikhale chisankho chabwino kwambiri m'malo ovuta, monga mapulatifomu obowola m'mphepete mwa nyanja ndi mafakitale oyeretsera, komwe kukhudzana ndi zinthu zowononga ndi vuto.
Kupanga mapaipi olumikizidwa kawiri ndi njira yovuta yomwe imafuna kulondola komanso ukatswiri. Fakitale yathu ili ku Cangzhou City, Hebei Province, ndipo yakhala patsogolo pamakampani kuyambira pomwe idakhazikitsidwa mu 1993. Fakitaleyi ili ndi malo okwana 350,000 square meters, ili ndi katundu wokwana RMB 680 miliyoni, ndipo ili ndi ukadaulo wamakono komanso antchito aluso 680. Izi zimatithandiza kupanga mapaipi apamwamba a DSAW omwe amakwaniritsa zofunikira kwambiri pa zomangamanga zamakono komanso mafakitale.
Kuphatikiza apo, kusinthasintha kwa mapaipi olumikizidwa kawiri kumapitirira kugwiritsidwa ntchito kwawo kwachikhalidwe. Amagwiritsidwa ntchito kwambiri m'mapulojekiti a mphamvu zongowonjezwdwanso, monga minda yamphepo ndi dzuwa, komwe amagwira ntchito ngati njira zothandizira kapangidwe kake komanso njira zotumizira mphamvu. Pamene dziko lapansi likupita ku mayankho okhazikika a mphamvu, ntchito ya mapaipi olumikizidwa kawiri pothandizira kusinthaku sikoyenera kunyalanyazidwa.
Pomaliza, kugwiritsa ntchito kwa DoubleChitoliro Chopangidwa ndi WeldedMu zomangamanga zamakono ndi mafakitale ndi akuluakulu komanso osiyanasiyana. Amakwaniritsa miyezo ya ASTM A252, kuonetsetsa kuti miyezo yapamwamba kwambiri komanso magwiridwe antchito akwaniritsidwa, zomwe zimapangitsa kuti akhale chisankho chodalirika kwa mainjiniya ndi akatswiri omanga. Pamene makampani akupitilizabe kusintha ndikukumana ndi mavuto atsopano, kufunika kwa zipangizo zodalirika monga Double Welded Pipe kudzakula kokha. Kudzipereka kwathu popanga mapaipi apamwamba a gasi a DSAW kwatipanga kukhala atsogoleri m'munda, okonzeka kukwaniritsa zofunikira zamtsogolo. Kaya m'magawo omanga, mafuta ndi gasi kapena mphamvu zongowonjezwdwanso, Double Welded Pipe idzakhala ndi gawo lofunika kwambiri pakupanga zomangamanga zamtsogolo.
