ASTM A192 (ASME SA192) umuyoboro wibyuma numuyoboro wa karubone utagira ikizinga ukoreshwa mubushuhe bwo hejuru hamwe n’umuvuduko mwinshi kandi ukoreshwa cyane mubyuma no guhanahana ubushyuhe.
Diameter yo hanze: 1/2 ″ - 7 ″ (12,7 mm - 177.8 mm);
Ubunini bw'urukuta: 0.085 ″ - 1.000 ″ (2,2 mm - 25.4 mm);
Ubundi bunini bw'icyuma gishobora gutangwa nkuko bisabwa, mugihe ibindi bisabwa byose bya A192 byujujwe.
ASTM A192 yakozwe ikoresheje inzira idafite gahunda kandi irashyushye cyangwa yarangije ubukonje nkuko bisabwa;
Nanone, imiyoboro yerekana ibyuma igomba kwerekana niba umuyoboro wibyuma ushyushye cyangwa urangije ubukonje.
Kurangiza bishyushye: Yerekeza kubikorwa byo kurangiza ibipimo byanyuma byicyuma muburyo bushyushye.Nyuma yuko umuyoboro wibyuma umaze gutunganywa bishyushye nko kuzunguruka cyangwa gushushanya bishyushye, ntabwo bikonje bitunganijwe.Ibyuma bishyushye byuzuye ibyuma bifite ubukana no guhindagurika ariko bifite kwihanganira binini.
Ubukonje burangiye: Umuyoboro wibyuma utunganyirizwa kurwego rwa nyuma nuburyo bukonje bukora nko gukonjesha cyangwa gushushanya ubukonje mubushyuhe bwicyumba.Imiyoboro ikonje ikonje ifite uburyo bunoze bwo kwihanganira ibipimo kandi byoroshye ariko birashobora kwigomwa gukomera.
Ibyuma bishyushye birangiye bidafite ibyuma ntibisaba kuvura ubushyuhe.
Imiyoboro ikonjesha ikonje itagira ubushyuhe ikorerwa ubushyuhe ku bushyuhe bwa 1200 ° F [650 ° C] cyangwa hejuru yayo nyuma yo kuvura ubukonje bwa nyuma.

ASTM A192 ntabwo yemerera kongeramo ibindi bintu mubigize imiti.

Keretse niba byavuzwe ukundi muri ASTM A192, ibikoresho byatanzwe muriki gisobanuro bigomba kuba bihuye nibisabwaASTM A450 / A450M.
Ubukomezi bwa Rockwell: 77HRBW.
Ku miyoboro y'ibyuma ifite uburebure bw'urukuta ruri munsi ya 0.2 "[5.1 mm].
Brinell Gukomera: 137HBW.
Ku rukuta rw'icyuma rufite uburebure bwa 0.2 "[5.1 mm] cyangwa zirenga.
Kubisabwa byihariye byo gukora, reba ASTM A450, Ingingo ya 23.
· Inshuro: Buri muyoboro wicyuma ukorerwa test ya hydrostatike.
· Igihe: Komeza igitutu ntarengwa byibuze amasegonda 5.
· Agaciro k'amazi: Kubarwa ukoresheje formula ikurikira.Reba igice.
Inch - Ibice bya Pound: P = 32000 t / D.
SI Ibice: P = 220.6t / D.
P = igitutu cya hydrostatike, psi cyangwa MPa;
t = uburebure bwurukuta rwerekanwe, muri. cyangwa mm;
D = yerekanwe hanze ya diameter, muri. Cyangwa mm.
· Igisubizo: Niba nta kumeneka mu miyoboro, ikizamini gifatwa nkaho cyatsinze.
Ubundi buryo bwo gupima hydrostatike nabwo birashoboka hamwe nigeragezwa ridakwiye.
Ariko, ibipimo ntibisobanura uburyo bwo kugerageza butangiza.
Imiyoboro iyo yinjijwe muri boiler igomba guhagarara kwaguka no kwerekanwa iterekanye ibice cyangwa inenge.Imiyoboro ya superheater iyo ikoreshejwe neza igomba guhagarara ibikorwa byose byo guhimba, gusudira, no kunama bikenewe mubisabwa nta guteza imbere inenge.
Botop Steelni ubuziranenge bwo mu rwego rwo hejuru bwo gusudira ibyuma bya karuboni ikora kandi ikanatanga ibicuruzwa biva mu Bushinwa, kandi ikanabika ibyuma bidafite ibyuma, biguha ibisubizo byinshi byicyuma!
Twandikirekubijyanye n'amagambo yavuzwe n'Ubushinwa butagira ibyuma.
