Chitoliro Chopanda Msoko cha A106
Chitoliro chachitsulo chosasunthika cha ASTM A106 ndi chitoliro chachitsulo chosasunthika cha ku America chopangidwa ndi zitsulo za kaboni wamba.
Chiyambi cha Zamalonda
Chitoliro chachitsulo chosasunthika cha ASTM A106 ndi chitoliro chachitsulo chosasunthika chopangidwa ndi zitsulo za kaboni za ku America. Ndi mzere wautali wachitsulo wokhala ndi gawo lopanda kanthu komanso wopanda zolumikizira kuzungulira mphepete. Mapaipi achitsulo ali ndi gawo lopanda kanthu ndipo amagwiritsidwa ntchito kwambiri ngati mapaipi onyamulira madzi, nthawi zambiri m'malo otentha kwambiri komanso opanikizika kwambiri. Mapaipi achitsulo chosasunthika cha ASTM A106 amatha kugawidwa m'mapaipi opindidwa ndi kutentha, mapaipi opindidwa ndi ozizira, mapaipi okokedwa ozizira, mapaipi otulutsidwa, ndi zina zotero malinga ndi njira zosiyanasiyana zopangira. Mapaipi opindidwa ndi kutentha nthawi zambiri amapangidwa pazida zodzipangira zokha. Chubu cholimba chimawunikidwa ndipo zolakwika pamwamba zimachotsedwa, kudula kutalika kofunikira, pakati pa mbali yomaliza ya chubu chopanda kanthu, kenako nkutumizidwa ku uvuni wotenthetsera kuti chitenthetse, ndikubowoledwa pamakina opindika. Pakubowoledwa, chubucho chimazungulira mosalekeza ndikupita patsogolo, ndipo pansi pa ntchito ya mphero yozungulira ndi pamwamba, pang'onopang'ono pamakhala dzenje mkati mwa chubu chowonongeka, chomwe chimatchedwa chubu cha capillary. Kenako imatumizidwa ku makina odzipangira okha mapaipi kuti ipitirire, ndipo makulidwe a khoma amasinthidwa mofanana mu makina onse. Makina opangira kukula amagwiritsidwa ntchito popangira kukula kuti akwaniritse zofunikira zonse. Kugwiritsa ntchito mphero yozungulira mosalekeza popanga mapaipi osagwedezeka a ASTM A106 ndi njira yapamwamba. Mapaipi osagwedezeka a ASTM A106 ali ndi ntchito zosiyanasiyana, makamaka zomwe zimagwiritsidwa ntchito ngati mapaipi kapena zigawo zomangira zonyamulira madzi. Njira ziwirizi zimasiyana malinga ndi kulondola, khalidwe la pamwamba, kukula kochepa, makhalidwe a makina, ndi kapangidwe kake kakang'ono.

Chitoliro chachitsulo chosasunthika cha ASTM A106Gr.B ndi chitsulo chotsika mpweya chomwe chimagwiritsidwa ntchito kwambiri, chomwe chimagwiritsidwa ntchito kwambiri m'mafakitale a petroleum, mankhwala ndi boiler. Zipangizozi zili ndi mphamvu zabwino zamakanika. Chitoliro chachitsulo cha A106-B ndi chofanana ndi chitoliro chachitsulo chosasunthika chachitsulo cha dziko langa cha 20, ndipo chimagwiritsa ntchito chitoliro chachitsulo chosasunthika cha ASTM A106/A106M chotentha kwambiri, kalasi B. Chimawoneka kuchokera ku muyezo wa ASME B31.3 chemical plant and oil refinery pipeline: A106 magwiritsidwe ntchito a kutentha: -28.9~565℃.
Chitoliro chachitsulo chopanda msoko cha ASTM A53, choyenera makina opopera mphamvu, mapaipi a mapaipi ndi mapaipi opopera mphamvu okhala ndi kutentha kosakwana 350°C.
Chitoliro chachitsulo chopanda msoko ASTM A106 chogwiritsidwa ntchito kutentha kwambiri, choyenera kutentha kwambiri. Chogwirizana ndi chitoliro chachitsulo chamtundu wa Nambala 20.
ASTM ndiye muyezo wa American Materials Association, womwe ndi wosiyana ndi njira yogawa m'magulu yapakhomo, kotero palibe muyezo wokhwima wogwirizana. Pali mitundu yosiyanasiyana ya zinthu zomwe zili mu mtundu womwewo, kutengera momwe mumagwiritsira ntchito.
Chitoliro chachitsulo chosasunthika cha ASTM A106 chimaphatikizapo njira ziwiri: kukoka kozizira ndi kugwedezeka kotentha. Kuwonjezera pa njira zosiyanasiyana zopangira, ziwirizi ndizosiyana kulondola, khalidwe la pamwamba, kukula kochepa, makhalidwe a makina, ndi kapangidwe ka bungwe. Chimagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana monga mafuta, makampani opanga mankhwala, ma boiler, malo opangira magetsi, zombo, kupanga makina, magalimoto, ndege, ndege, mphamvu, geology, zomangamanga, ndi makampani ankhondo.
