Chii chinonzi Pressure Vessel Steel Plate?
Pressure mudziyo simbi ndiro inovhara huwandu hwesimbi mamakisi akagadzirirwa kushandiswa mukumanikidza ngarava, boilers, kupisa kupisa uye chero imwe ngarava ine gasi kana mvura pane yakanyanya kumanikidza. Mienzaniso yakajairika inosanganisira magasi egasi ekubikira uye ekuwelda, masilinda eokisijeni ekunyura uye mazhinji ematangi makuru esimbi aunoona munzvimbo inocheneswa oiri kana makemikari. Kune huwandu hukuru hwemakemikari akasiyana uye mvura iyo yakachengeta uye yakagadziriswa pasi pekumanikidzwa. Izvi zvinotangira kubva kuzvinhu zvisina kunaka zvakaita semukaka nemafuta emichindwe kusvika kumafuta asina kuchena uye gasi rechisikigo uye madhiraidhi azvo kune anouraya acid uye makemikari akadai semethyl isocyanate. Saka pamaitiro aya anoda kuti gasi kana mvura inopisa zvakanyanya, nepo mamwe achiine patembiricha yakaderera. Nekuda kweizvozvo kune kwakasiyana kwakasiyana kwakasiyana kudzvanywa mudziyo simbi mamakisi anosangana akasiyana ekushandisa kesi.
Kazhinji izvi zvinogona kukamurwa kuita mapoka matatu. Iko kune boka rekabhoni simbi yekumanikidza mudziyo mamakisi. Aya ndiwo masimbi akajairwa uye anogona kurarama neakawanda maapplication uko kune yakaderera corrosion uye yakaderera kupisa. Sezvo kupisa uye ngura zvichiwedzera mhedzisiro pamahwendefa esimbi chromium, molybdenum uye nickel zvinowedzerwa kupa kumwe kuramba. Pakupedzisira sezvo % yechromium, nickel uye molybdenum zvichiwedzera une mahwendefa esimbi asingasviki anoshandiswa zvakanyanya uye uko kusvibiswa kweoxide kunoda kudzivirirwa - zvakadai mumaindasitiri ezvekudya nemishonga.

Pressure Vessel Steel Plate Applications
● A516 simbi ndiro ndiyo kabhoni simbi ine zvirevo zvekumanikidza ngarava mahwendefa uye ine mwero kana yakaderera tembiricha sevhisi.
● A537 inogadziriswa nekupisa uye nekudaro, inoratidza goho rakakura uye simba rekusimba kupfuura mamwe magiredhi eA516.
● A612 inoshandiswa kune yakadzikama uye yakaderera tembiricha yekumanikidza mudziyo zvikumbiro.
● A285 mahwendefa esimbi anogadzirirwa fusion-welded pressure midziyo uye mahwendefa anowanzo kupiwa mumamiriro ekutenderera.
● TC128-giredhi B yakagadziridzwa uye yakashandiswa mumotokari dzenjanji dzakamanikidzwa.
