12Cr1MoV high pressure boiler chubuidapangidwa kuchokera kuchitsulo choyambirira cha 12xm (0.5% Cr-Mo-V) mpaka chitsulo cha 12x1m (1% Cr-Mo-V) powonjezera zomwe zili mu Cr.The mankhwala zikuchokera12Cr1MoV Aloyi Yopanda Zitsulo Tubendi osavuta, okwana aloyi zili zosakwana 2%, ndipo ali ndi ndondomeko yabwino ndi katundu thupi.Pakali pano, izo zalembedwa mu seamless zitsulo chitoliro muyezo wa kukanika kukatentha ku China (GB5310-2008).Makalasi achitsulo ofanana omwe amagwiritsidwa ntchito kwambiri kunja akuphatikizapo ASTM a405 p24 (1% CrMoV, USA), bs3604 (0,5% CrMoV, l% CrMoV, UK), din13crmov42, 10crmosiv7 (Germany), etc.
Pakadali pano,12Cr1MoV Chitoliro Chopanda Zitsuloamagwiritsidwa ntchito kwambiri mu Superheater, mutu ndi njira yayikulu yopopera yothamanga kwambiri, kuthamanga kwambiri komanso ma boiler ocheperako magetsi kunyumba ndi kunja.Chitsulo ichi chakhala chimodzi mwazinthu zazikulu zamafakitale opangira magetsi ndi boiler mumakampani aku China.
Pakadali pano,12Cr1MoV Seamless Steel Tubeamagwiritsidwa ntchito kwambiri m'mbali zotsatirazi:
(1) Amagwiritsidwa ntchito kwambiri popangira chitoliro champhamvu kwambiri, chitoliro cha mpweya, chitoliro chachikulu cha nthunzi, chitoliro chotenthetsera ndi mbali zina za zida zowotchera, makamaka mu boiler yothamanga kwambiri komanso yothamanga kwambiri, chitsulo cha 12Cr1MoVG chotsika cha alloy chosagwira kutentha chimagwiritsidwa ntchito kwambiri.
(2) Amagwiritsidwa ntchito makamaka pa shaft yayikulu,] chowongolera, chozungulira, chomangira (bawuti ndi nati), silinda, chipinda cha nozzle, valavu yopaka mafuta, diaphragm ndi zida zina zamasamba za turbine ya nthunzi.
(3) Amagwiritsidwa ntchito kwambiri kuchepetsa kutentha kwa rotor ndi tsamba mu injini yotentha ya gasi kufika pafupifupi 550 ℃, kuti awonjezere kugwiritsa ntchito chitsulo chochepa cha alloy kutentha zosagwira mu injini ya gasi.
(4) Angagwiritsidwe ntchito kupanga mpweya chopangira makina ozungulira chozungulira, chowongolera, chomangira ndi mbali zina ndi kutentha ntchito m'munsimu 570 ℃.
(5) Amagwiritsidwa ntchito makamaka popanga chitoliro cha ng'anjo, chotenthetsera kutentha ndi mapaipi ena otenthetsera pamagetsi ndi zida zamafuta.
