ASTM A335 P11umuyoboro wibyuma numuyoboro wa ferritic udafite uburinganire bwicyuma cya serivise yubushyuhe bwo hejuru, UNS K11597.
P11 ni chromium-molybdenum ivanze na chromium ya 1,00-1.50% hamwe na molybdenum ya 0.44-0.65%.
Bikunze gukoreshwa mubyuma, superheater, hamwe no guhanahana ubushyuhe mumashanyarazi no mumashanyarazi.
Ibisabwa bya tekinike yaASME SA335naASTM A335ni kimwe, kugirango byoroshye kwerekana, tuzakoresha "ASTM A335" kugirango twereke aya mahame yombi.

Keretse niba byavuzwe ukundi muri A335, ibikoresho byatanzwe muribi bisobanuro bigomba kuba bihuye nibisabwa bikenewe muri iki gihe cyihariye.A999 / A999M.
ASTM A335 umuyoboro wibyuma ugomba kubanta nkomyi.Imiyoboro idafite ibyuma itanga ubwizerwe nuburinganire iyo ikorewe umuvuduko mwinshi nubushyuhe.
Ikidodo kirashobora gushyirwa muburyo bwihariye nkubukonje bukonje kandi bushyushye burangiye, bitewe na progaramu yihariye nubunini.
Igishushanyo gikonje gikunze gukoreshwa kumurambararo muto cyangwa kubituba bisaba ubuziranenge kandi bwiza bwubuso.Kurangiza bishyushye bikoreshwa mugukora imiyoboro minini igororotse kandi yuzuye urukuta.
Hano hepfo ni imbonerahamwe yerekana uburyo bwo gukora ibyuma bishyushye birangiye.
Gushyushya ibikoresho bya P11 birashobora kuba byuzuye cyangwa isothermal annealing cyangwa ubushyuhe nyuma yubusanzwe, kandi mugihe gisanzwe nubushyuhe, ubushyuhe bwubushyuhe bugomba kuba nibura 1200 ° F (650 ° C).
Duhereye ku bigize imiti, dushobora kubibona byoroshyeP11 ni chromium-molybdenum.
Chromium-molybdenum alloys ni urwego rwibyuma hamwe na chromium (Cr) na molybdenum (Mo) nkibintu nyamukuru bivanga.Kwiyongera kwibi bintu byongera cyane imbaraga, gukomera, kwihanganira kwambara, no kurwanya ruswa.Ku bushyuhe bwinshi, Cr-Mo ibinyobwa birashobora kugumana imiterere myiza yubukanishi nuburyo buhamye.
Cr.
Mo: Yongera imbaraga zumusemburo, cyane cyane mubushyuhe bwo hejuru, atezimbere imirwanyasuri, kandi akongerera imbaraga ubushyuhe bwo hejuru bwibikoresho.
1. Umutungo utoroshye
Ikizamini cya tensile gikunze gukoreshwa mugupimagutanga imbaraga, imbaraga, naelongation ya progaramu yubushakashatsi bwicyuma, kandi ikoreshwa cyane mubintu bifatika byikizamini.
AImbonerahamwe 5 itanga agaciro ntarengwa kabaruwe.
Aho uburebure bwurukuta buri hagati yagaciro kombi hejuru, agaciro ntarengwa kuramba kugenwa na formula ikurikira:
Longitudinal, P11: E = 48t + 15.00 [E = 1.87t + 15.00]
Guhindura, P11: E = 32t + 15.00 [E = 1.25t + 15.00]
aho:
E = kurambura muri 2 muri. Cyangwa 50 mm,%,
t = ubunini nyabwo bwikigereranyo, muri. [mm].
2. Gukomera
Icyiciro cya P11 ntabwo gisaba kugerageza gukomera.
Agaciro kerekana agaciro karatanzwe hepfo.
Imiterere idasanzwe:
Ubukomere busanzwe buri hagati ya 150 na 200 HB.
Imiterere isanzwe kandi ituje:
Ubukomere buri hagati ya 170 na 220 HB.
Imiterere ikaze kandi ituje:
Gukomera birashobora kugera kuri 250 kugeza 300 HB cyangwa birenga, bitewe n'ubushyuhe n'ubushyuhe.
3. Gahunda Zigerageza
Ibintu byubushakashatsi bikurikira ntibisabwa ibintu byikizamini, nibiba ngombwa birashobora kugenwa numushyikirano.

Hydrotest ya P11 igomba kubahiriza ibisabwa bikurikira.
Hanze ya diameter ＞ 10in.[250mm] n'ubugari bw'urukuta ≤ 0,75in.[19mm]: iki kigomba kuba ikizamini cya hydrostatike.
Ubundi bunini bwo gupima amashanyarazi adasenya.
Ibizamini bya hydrostatike ikurikira byakusanyirijwe mubisabwa ASTM A999:
Kubyuma bya ferritic alloy ibyuma hamwe nicyuma kitagira umuyonga, urukuta rushyirwaho igitutu kitari munsi60% byimbaraga ntoya yatanzwe.
Umuvuduko wikizamini cya hydro ugomba kubungabungwa byibuze 5snta kumeneka cyangwa izindi nenge.
Umuvuduko w'amaziirashobora kubarwa ukoresheje formula:
P = 2St / D.
P = umuvuduko wikizamini cya hydrostatike muri psi [MPa];
S = imiyoboro y'urukuta muri psi cyangwa [MPa];
t = uburebure bwurukuta rwerekanwe, uburebure bwurukuta rwizina ukurikije umubare wateganijwe wa ANSI cyangwa inshuro 1.143 zuburebure bwurukuta ntarengwa, muri. [mm];
D = yerekanwe hanze ya diameter, diameter yo hanze ihuye nubunini bwa ANSI bwagenwe, cyangwa diameter yo hanze ibarwa wongeyeho 2t (nkuko byasobanuwe haruguru) kuri diameter imbere, muri.
Buri muyoboro ugomba gusuzumwa nuburyo bwikizamini budasenya hakurikijwe imyitozoE213, ImyitozoE309, cyangwa ImyitozoE570.
Impinduka zemewe muri Diameter
Umuyoboro wateganijwe kuriimbere ya diameter, diameter y'imbere ntishobora gutandukana kurenza ± 1% uhereye kumurambararo wimbere.
Igituba cyateganijwe muriNPS [DN] cyangwa ibipimo byo hanzentigomba gutandukana hanze ya diametero kurenza uko bigaragara mumbonerahamwe ikurikira.
Impinduka zemewe muburyo bwurukuta
Ibipimo by'ubugari bw'urukuta bigomba gukorwa hifashishijwe imashini zikoresha imashini zikoresha imashini zipima neza.Iyo habaye impaka, ibipimo byagenwe hakoreshejwe imashini zikoresha imashini bizatsinda.
Uburebure bwurukuta ntarengwa na diameter yo hanze kugirango bigenzurwe kugirango hubahirizwe iki gisabwa kumuyoboro wateganijwe na NPS [DN] numero yingengabihe irerekanwa muriASME B36.10M.
Mubisanzwe bikoreshwa mumashanyarazi, superheater, hamwe no guhanahana ubushyuhe mumashanyarazi no mumashanyarazi.
Amashanyarazi: P11 ikoreshwa cyane mu kubaka amashyiga kubera ko irwanya ubushyuhe bwinshi n’umuvuduko, cyane cyane mu bice bikorerwa ubushyuhe bukabije n’umuvuduko.
Amashanyarazi: Byakoreshejwe mukongera ubushyuhe bwamazi kugirango turusheho kuzamura ubushyuhe bwumuriro.p11 yemeza ko imbaraga nigihe kirekire cyibikoresho bigumaho no mubushyuhe bwinshi.
Guhindura ubushyuhe: P11 yongerera ruswa hamwe nubushyuhe bwo hejuru bwo guhinduranya ubushyuhe, bityo bikazamura ubwizerwe numutekano wibikoresho.
Sisitemu yo kuvoma: Sisitemu yo kuvoma mu bimera bya shimi ikenera gutwara amazi yubushyuhe bwo hejuru cyangwa amavuta.imbaraga zubushyuhe bwo hejuru hamwe nibikoresho byiza bya P11 bituma biba byiza kuriyi porogaramu.
