12Cr1MoVG mkulu kuthamanga aloyi zitsulo chitoliro chitsimikizo khalidwe
Malo ogwiritsira ntchito a 12Cr1MoVG alloy pipe akukulitsidwa kuti apereke malo ambiri opititsa patsogolo makampani. Malinga ndi kafukufuku wa 12Cr1MoVG aloyi chitoliro nthambi ya China Special Zitsulo Association, kufunika mkulu-pressure 12Cr1MoVG aloyi chitoliro kutalika mu China adzawonjezeka ndi 10-12% pachaka m'tsogolo. Gulu la 12Cr1MoVG aloyi chitoliro.
Ubwino waukulu wa 12Cr1MoVG alloy pipe ndikuti ukhoza kubwezeretsedwanso 100%, zomwe zikugwirizana ndi ndondomeko ya dziko la chitetezo cha chilengedwe, kuteteza mphamvu ndi kusungirako zinthu. Ndondomeko ya dziko imalimbikitsa kukulitsidwa kwa gawo la ntchito ya chitoliro chapamwamba cha 12Cr1MoVG.
Chifukwa cha njira zosiyanasiyana zopangira, zimagawidwa mu chitoliro chopanda chitsulo chotentha (chotuluka) komanso chitoliro chozizira (chokuta) chosasunthika. Chitoliro chozizira (chokuta) chimagawidwa mu chitoliro chozungulira ndi chitoliro chapadera.
a. Ndondomeko yoyenda mwachidule
Chitoliro chachitsulo chotentha (chotuluka) chosasokonekera: chubu chozungulira chilibe kanthu → Kutenthetsa → kubowoleza → kugudubuza katatu kopingasa, kugudubuza mosalekeza kapena kutulutsa → kuvula chitoliro → kukula (kapena kuchepetsa) → kuzizira → chubu chopanda kanthu → kuwongola → kuyesa kwa hydrostatic (kapena kuzindikira zolakwika) → kuyika chizindikiro → malo osungira.
Chitoliro chozizira chokoka (chogudubuzika) chosasokonekera chachitsulo: chubu chozungulira chilibe kanthu → kutentha → kubowoleza → mutu → kupukuta → pickling → kudzola mafuta (kubisala zamkuwa) → zojambula zambiri zozizira (zozizira) → chubu chopanda kanthu → chithandizo cha kutentha → kuwongola → kuyesa kwa hydrostatic (cholakwika kuzindikira) → kuyika chizindikiro → kusunga.
