Chomwe chimagwiritsidwa ntchito kwambiri pobowola mafuta ndi chotengera chamafuta cha API choperekedwa ndi Hunan Great Steel Pipe Co., Ltd. Amagwiritsidwanso ntchito limodzi ndikubowola mapaipi, kubowola kolala, mapaipi apakati, ndi mapaipi achitsulo obowola ang'onoang'ono.Ntchito yaikulu ya API mafuta casing ndi kuthandizira khoma la chitsime cha mafuta panthawi yonse yobowola ndikumaliza, zomwe zingathe kuonetsetsa kuti chitsime chonse cha mafuta chikugwira ntchito bwino.

Chitoliro chosungira mafuta cha API choperekedwa ndi Hunan Great Steel Pipe Co., Ltd ndi mtundu wa mapaipi omwe amanyamula mafuta ndi zinthu zina zopangira.Zofunikira paukadaulo wa chitoliro chamafuta cha API choperekedwa ndi Hunan Great Steel Pipe Co., Ltd ndizovuta kwambiri.Pakati pawo, chofunikira kwambiri ndi kutentha, komwe kumafuna kutentha kofananira pagawo lililonse lokonzekera.Mwachitsanzo, AC1 ya 27MnCrV chitsulo imafanana ndi kutentha kwa madigiri 736 Celsius.Kutentha kwa kutentha kuyenera kuyendetsedwa pakati pa 740-810 digiri Celsius panthawi yozimitsa kutentha.Onetsetsani kuti kutentha kuzimitsa kutentha ndi madigiri 780, ndi nthawi yotentha ndi yoposa mphindi 15;kutentha kwapang'onopang'ono kwa casing yamafuta a API yoperekedwa ndi Hunan Great Steel Pipe Co., Ltd itatha kuzimitsa iyenera kuyendetsedwa pa madigiri 630, ndikuwotcha kuyenera kuyendetsedwa.Nthawi iyenera kukhala yopitilira mphindi 50.Ngati mukufuna kukonza kulimba kwa chosungira chamafuta a API, kutentha kwa kutentha kuyenera kuyendetsedwa pakati pa α + γ, ndipo kumafunika kuzimitsa thumba lamafuta a API ndikusunga gawo la ferrite yosungunuka.Chifukwa chake, thumba lamafuta la API limatenthedwa ndi kutentha kwapang'onopang'ono, komwe kumatha kupititsa patsogolo kulimba kwa mafuta a API, ndikuwongolera kulimba kwamphamvu komanso kukana kuwonongeka kwa casing yamafuta a API.

Kuwongolera mwamphamvu kuyenera kuchitidwa panthawi yochizira chitoliro chamafuta cha API choperekedwa ndi Hunan Great Steel Pipe Co., Ltd. Mwa njira iyi yokha yomwe chitoliro cha API chosungira mafuta cha API choperekedwa ndi Hunan Great Steel Pipe Co., Ltd. wotsimikizika.Ili ndi kulimba kwambiri komanso magwiridwe antchito ena pakagwiritsidwe ntchito.Chophimba chamafuta cha API choperekedwa ndi Hunan Great Steel Pipe Co., Ltd chimatengera njira ya cryogenic quenching processing kuti muchepetse kupsinjika kwanthawi yayitali.Nthawi zambiri, kutentha kwa cryogenic quenching ndikotsika kuposa kutentha kwanthawi zonse, kotero sikophweka kuyambitsa Hunan pakuzimitsa.Kusinthika kwa casing yamafuta a API koperekedwa ndi Great Steel Pipe Co., Ltd. Kugwiritsa ntchito njira yochizira sikungangotsimikizira kupanga kwanthawi zonse komanso kumapereka zida zopangira waya wotsatira.
