2507 intsimbi yokutshintshiselana kobushushu
Ulwazi olusisiseko
Iimathiriyeli ekrwada ezisetyenziswa lushishino zithengwa kubathengisi abathenjiweyo kwimarike ezithi zivavanywe ngakumbi umgangatho lishishini.Ngoyilo oluthambileyo, oomatshini banamhlanje kunye nobuchwepheshe be-inventory, abatshintshi bobushushu kunye ne-U tubes zenziwe.Yonke inkqubo yokuqulunqa yenziwa phantsi konikezelo olungqongqo lwabasebenzi bezoshishino.
Konke malunga nabaTshintshi bobushushu kunye neetyhubhu ze-U
Imibhobho egobileyo yenziwa kuqala ibe yityhubhu evulekileyo engenamthungo ize idityaniswe ngakumbi ngokusetyenziswa kolu shishino.Imiphetho emihle yeetyhubhu ze-U zifudunyezwa ngokucokisekileyo kwaye emva koko zifakwe kwiqondo lobushushu eliphezulu kunye noxinzelelo.
Ukuthetha malunga nabaTshintshi be-Heat, basetyenziselwa ukuhambisa ubushushu ukusuka kwindawo ukuya kwenye indawo ekupheleni ngokuhambisa ubushushu bangaphandle phakathi kwamanzi angaphezu kwamabini.Aba batshintshiselwano bafumaneka kakhulu kwiifriji kunye nezicelo zemizi-mveliso yeemoto.Ukugqithiswa kobushushu kwaba batshintshiselwano kufezekiswa ngokugqithiswa kolwelo olunye kwiityhubhu ezinxuseneyo ezithi ke zifumaneke kwelinye icala lemibhobho engenamthungo.
Ukuthetha ngebakala elisetyenziselwa ukwenziwa kweetyhubhu ze-U kunye nabatshintshi be-Heat, ibakala le-Super Duplex Steel UNS S32750 lisetyenziswa kakhulu.I-Super Duplex Steel ye-UNS S32750 yoTshintshiselwano loBushushu kunye ne-U Tubes ibonisa ukuxhathisa okungaqhelekanga ku-corrosion, kunye nokumelana ne-oxidation.Ubukho be-molybdenum ephezulu, i-chromium kunye ne-nitrogen kwibakala kubangela ukomelela okuphezulu kunye nokuqina kweemveliso.
Zeziphi iziqinisekiso zovavanyo ezibonelelwayo?
Ishishini libonelela ngengxelo ye-MTC, ingxelo yezinto eziluhlaza, isatifikethi sokuzihlola kunye neengxelo zovavanyo lweradiography kunye neSuper Duplex Steel UNS S32750 Heat Exchange & U Tubes.
