2507 duplex idafite ibyuma bya valve ikoresha JB / T7746 “Compacticyuma”Inganda zimenyekanisha
Isosiyete yacu izobereye mu gukora amazi yo mu nyanja 2205 duplex idafite ibyuma byumupira wumupira wa 2507 duplex idafite ibyuma ibyuma byumupira 2205 duplex ibyuma bitagira ibyuma byisi 2507 duplex ibyuma bitagira ibyuma byisi andika akayunguruzo 2507 duplex idafite ibyuma bishungura 2205 kugenzura valve 2507 kugenzura valve nibindi bicuruzwa
Amazi yo mu nyanja 2205 duplex ibyuma bya valve molybdenum duplex ibyuma bitagira umuyonga bifite imbaraga zo kurwanya ruswa ya chloride yangirika mukibazo gike. Mubisanzwe, 18-8 ubwoko bwa austenitis butagira ibyuma bikunda guhangayikishwa no kuvunika kwangirika kwa chloride idafite aho ibogamiye hejuru ya 60C. Guhindura ubushyuhe, guhumeka hamwe nibindi bikoresho bikozwe muri ubu bwoko bwibyuma bidafite ingese mu nganda zinganda za chloride na hydrogen sulfide zifite imyumvire yo kubyara imvune zangirika, mugihe ibyuma bya duplex bitagira umuyonga bifite imbaraga zo guhangana.
. Ubushobozi bukomeye bwo gushira ibyuma bya duplex bidafite ibyuma bisa niby'ibyuma bya austenitike bidafite ibyuma bimwe (PRE = Cr% + 3.3Mo% + 16N%). Kurwanya ruswa ya duplex idafite ibyuma na austenitis ibyuma bitagira ibyuma bisa nibya AI 316L. Kurwanya ruswa ya chromium duplex ibyuma bitagira umuyonga birimo 25% Cr, cyane cyane azote, iruta iya AI 316L.
(3) Hamwe no kurwanya ruswa nziza yo kunanirwa no kwambara imikorere. Mubihe bimwe na bimwe byangirika, bikwiranye no gukora pompe, valve nibindi bikoresho byamashanyarazi.
(4) Ibikoresho byiza byuzuye. Imbaraga nyinshi numunaniro imbaraga, imbaraga zitanga ni 18-8 ubwoko bwa austenitike idafite ibyuma inshuro 2. Muburyo bukomeye bwo gukemura, kurambura bigera kuri 25%, kandi agaciro gakomeye AK (V-notch) kari hejuru ya 100J.
.
. Irashobora kuzunguruka mu buryo butaziguye kugirango ikore isahani y'ibyuma idahimbye. Duplex ibyuma bidafite ibyuma birimo chromium ndende (25% Cr) biragoye gato ugereranije no gutunganya amashyanyarazi ya austenitike, birashobora kubyazwa amasahani, imiyoboro ninsinga.
.
. Irakwiriye kandi gukora umuyoboro woguhindura ubushyuhe, kandi uburyo bwo guhererekanya ubushyuhe burenze ubw'icyuma cya austenitis.
. Hasi ya chromium yibigize duplex idafite ibyuma, ntigabanye ingaruka zicyiciro kimwe.
JB / T7746 Igipimo cy’inganda “Compact Steel Valve” Inganda yerekana igishushanyo mbonera nogukora ibipimo ngenderwaho byo guhimba ibyuma bito bito bya diameter mu gihugu cyacu ni JB / T 7746-2006 “Compact Steel Valve”, igipimo cyemejwe kandi gisohoka ku ya 14 Nzeri 2006 , itariki yo kuyishyira mu bikorwa ni 1 Werurwe 2007. Aho kugirango JB / T 7746-1995 “Kugabanya diameter yahimbwe ibyuma Valve”.

Kugeza ubu, igishushanyo mbonera nogukora ibipimo byibyuma byahimbwe na diameter ntoya mu gihugu cyacu ni JB / T 7746-2006 “Compact Steel Valve”, iki gipimo cyemejwe kandi gitangwa ku ya 14 Nzeri 2006, itariki yo kuyishyira mu bikorwa ni 1 Werurwe 2007 , mu mwanya wa JB / T 7746-1995 “Kugabanya diameter Yakozwe na Valve Steel Valve”.
Iri vugurura ryerekeza ku kigo cy’ibikomoka kuri peteroli muri Amerika API 602-1998 “Irembo ry’Icyuma Cyuzuza Ibyuma byuzuzanya, bifatanye, byegereye kandi byongerewe umubiri” kandi bihuza na API 602 mubisabwa tekinike.
Ibipimo ngenderwaho byerekana ubwoko bwimiterere, ibisabwa bya tekiniki, uburyo bwikizamini, amategeko yubugenzuzi, ibimenyetso nibisabwa kugirango igabanuke rya diameter yagabanutse.
Ibipimo ngenderwaho bikurikizwa kumarembo, isi, kuzamura no kugenzura kugenzura. Kumurongo wimbere hamwe na sock yo gusudira hamwe numuvuduko wizina PN18 ~ PN250 nubunini bwizina DN8 ~ DN65; Birakoreshwa kandi kumuvuduko wizina PN18 ~ PN250, ingano yizina DN8 ~ DN100 flange ihuza hamwe na butt welding ihuza valve. Uburyo bukoreshwa mumazi, peteroli nibikomoka kuri peteroli, gaze gasanzwe, amavuta, nibindi.
Ibipimo ngenderwaho kandi bireba na valve ifite inzogera zifunze, igitutu nomero PN16 ~ PN250, ingano yizina DN8 ~ DN50.
