ASTM A53 ndi pulogalamu yolumikiziranachitsulo cha kabonizomwe zingagwiritsidwe ntchito ngati chitsulo chomangira kapena mapaipi otsika mphamvu.
Chitoliro cha ASTM A53 chachitsulo cha kaboni (ASME SA53) ndi chitoliro chophimba chitoliro chachitsulo chakuda ndi chotentha choviikidwa m'madzi chopanda msoko komanso cholumikizidwa kuchokera ku NPS 1/8″ mpaka NPS 26. A 53 idapangidwa kuti igwiritsidwe ntchito ndi makina komanso imapezekanso kuti igwiritsidwe ntchito nthawi zonse. Nthunzi, madzi, gasi ndi mpweya.
Chitoliro A53 chikupezeka m'mitundu itatu (F, E, S) ndi mitundu iwiri (A, B). A53 Mtundu F wopangidwa ndi kuwotcherera matako a uvuni kapena kuwotcherera mosalekeza msoko (Giredi A yokha) A53 Mtundu E ndi kuwotcherera mosalekeza (Magulu A ndi B).
Kalasi B A53mapaipi opanda msokondiye chinthu chathu chapamwamba kwambiri malinga ndi izi. Machubu a A53 nthawi zambiri amakhala ndi satifiketi ziwiri poyerekeza ndi machubu opanda msoko a A106 B.
ASTM A53chitoliro chachitsulo chosasunthikandi giredi yokhazikika ya ku America. A53-F ikugwirizana ndi zinthu zaku China Q235, A53-A ikugwirizana ndi zinthu zaku China Nambala 10, ndipo A53-B ikugwirizana ndi zinthu zaku China Nambala 20.
Njira Yopangira Mapaipi achitsulo chosasunthika amagawidwa m'mapaipi osasinthika otenthedwa ndi osalala komanso mapaipi osasinthika ozizira malinga ndi njira yopangira.
1. Njira yopangira chitoliro chachitsulo chosasunthika chotentha: chubu billet → kutentha → kuboola → ma roll atatu / kusuntha → kuchotsa chitoliro → kukula → kuziziritsa → kuwongola → kuyesa kwa hydraulic → kuyika chizindikiro → kuzindikira chitoliro chachitsulo chosasunthika chopanda lever. Zotsatira zake. 2. Njira yopangira chitoliro chachitsulo chosasunthika chokokedwa chozizira: chubu billet → kutentha → kuboola → kubisa → kusakaniza → kusakaniza mafuta → zojambula zambiri zozizira → chubu billet → chithandizo cha kutentha → kuwongola → kuyesa kwa hydraulic → kuyika chizindikiro → laibulale ya jakisoni.
Kugwiritsa ntchito1. Kapangidwe: mapaipi apansi panthaka, madzi apansi panthaka, mayendedwe a madzi otentha. 2. Makina, tchire lonyamula katundu, kukonza zida za makina, ndi zina zotero. 3. Zamagetsi: mapaipi a gasi, mapaipi amagetsi amadzi 4. Mapaipi oletsa kusinthasintha kwa mphamvu ya mphepo, ndi zina zotero.
