Isetyenziswa ikakhulu Ukwenza iNtsimbi yoLwakhiwo lweKhabhoni ekumgangatho oPhezulu, intsimbi yolwakhiwo lwe-alloy kunye nemibhobho yentsimbi ekwaziyo ukumelana nobushushu obungenamthungo kuxinzelelo oluphezulu nangaphezulu kweMibhobho yeBoiler yomphunga.
Isetyenziswa ikakhulu kuxinzelelo oluphezulu kunye nenkonzo yobushushu obuphezulu yeBoiler(Iityhubhu yeheater, Ityhubhu yeReheater, iThubhu yesiKhokelo soMoya, iityhubhu yomphunga oPhakamileyo kunye neziBoiler zoxinzelelo oluphezulu).Phantsi kwesenzo sobushushu obuphezulu beGesi yeFlue kunye noMphunga waManzi, iThubhu iya kuOxidize kwaye iCorrode.Kuyafuneka ukuba uMbhobho weNtsimbi ube Nozinzo oluPhezulu, ukuxhathisa okuPhezulu kwi-Oxidation kunye nokuCorrosion, kunye nokuzinza okuhle kwesakhiwo.
IBanga leNtsimbi yoLwakhiwo lweCarbon ekumgangatho oPhezulu: 20g, 20mng, 25mng
IBanga le-Alloy Structural Steel: 15mog, 20mog, 12crmog, 15crmog, 12cr2mog, 12crmovg, 12cr3movsitib, njl.

Ubude:
Ubude obuQhelekileyo beMibhobho yentsimbi Bungama-4 000 Mm ~ 12 000 Mm.Emva kokubonisana phakathi koMboneleli kunye noThengi, kwaye ugcwalise ikhontrakthi, inokunikezelwa iMibhobho yentsimbi enobude obungaphezu kwe-12 000 mm okanye mfutshane kunom 000 mm kodwa ingabi mfutshane kune-3 000 mm;Ubude obufutshane Inani lemibhobho yentsimbi engaphantsi kwe 4,000 mm kodwa hayi ngaphantsi kwe 3,000 mm ayizu kudlula kwi 5% yetotali yenani lemibhobho yentsimbi enikezelweyo.
Ubunzima bokuhanjiswa:
Xa uMbhobho wentsimbi uhanjiswa ngokoMda weDiyamitha yaNgaphandle yeSibizo kunye nokutyeba kweNdonga ngeNgcaciso okanye iDiyamitha eNgaphakathi eNgaphakathi kunye nokutyeba kweNdonga, uMbhobho wentsimbi uhanjiswa ngokoBubunzima obububo.Inokuthi kwakhona ihanjiswe ngokuhambelana nobunzima bobuNgqiqo.
Xa uMbhobho weNtsimbi uhanjiswa ngokoMda woMda oNgaphandle kunye noBuncinci bokutyeba kweendonga, iPipe yentsimbi ihanjiswa ngokobunzima obububo;Amaqela oBonelelo kunye neBanga ayathethathethana.Kwaye ibonisiwe kwikhontrakthi.Umbhobho weNtsimbi unokubonelelwa kwakhona ngokuhambelana nobunzima bobunzima.
Ukunyamezela Ubunzima:
NgokweeMfuno zoMthengi, emva kothethwano phakathi koMniki-nkonzo kunye noMthengi, kunye nakwiKhontrakthi, ukutenxa phakathi koBubunzima obububo kunye noBubunzima bobuNgqiqo boMbhobho wentsimbi yokuhanjiswa kuyakuhlangabezana nezi mfuno zilandelayo:
A) Umbhobho weNtsimbi omnye: ± 10%;
B) Ibhetshi nganye yeMibhobho yentsimbi enoBuncinane boBubungakanani be-10 T: ± 7.5%.
Uvavanyo lweHydraustatic:
Umbhobho weNtsimbi kufuneka uVavanywe ngokweHydraulically enye nenye.Uxinzelelo oluphezulu lovavanyo luyi-20 MPa.Ngaphantsi koxinzelelo lovavanyo, ixesha lokuzinzisa kufuneka lingabi ngaphantsi kwe-10 S, kwaye iPipe yensimbi akufanele ivuze.
Emva kokuba uMsebenzisi eVumelana, uvavanyo lweHydraulic lunokutshintshwa luVavanyo lwangoku lwe-Eddy okanye uvavanyo lokuvuza kweMagnetic Flux.
Uvavanyo olungonakaliyo:
Imibhobho efuna uPhononongo olungakumbi kufuneka ihlolwe ngokwe-Ultrasonically nganye nganye.Emva kokuba uThethathethwano lufuna imvume yeQela kwaye luchazwe kwiKhontrakthi, olunye uvavanyo olungabhubhisi lunokongezwa.
Uvavanyo lokucaba:
Iityhubhu ezinoMda waNgaphandle oMkhulu kune-22 mm ziya kuHlelelwa kuVavanyo lokuNcandwa.Akukho kuDelamination kubonakalayo, amabala amhlophe, okanye ubumdaka obunokuthi kwenzeke ngexesha lovavanyo lulonke.
Uvavanyo lokuvutha:
NgokweeMfuno zoMthengi kwaye zichazwe kwikhontrakthi, uMbhobho weSsimbi onoDayamitha waNgaphandle ≤76mm kunye noBungqingqwa beDonga ≤8mm Unokwenziwa Uvavanyo Lokuvutha .Uvavanyo lwenziwa kwiqondo lobushushu leGumbi ngeTaper ye60 °.Emva koKuvutha, iReyithi yokuFika kweDayimitha yaNgaphandle kufuneka ihlangabezane neemfuno zeTheyibhile ilandelayo, kwaye iMathiriyeli yoVavanyo akufuneki ibonise iintanda okanye iiRips.
Ukusungula izinto ezintsha, okugqwesileyo kunye nokuthembeka zezona nqobo zisemgangathweni zeshishini lethu.Le migaqo namhlanje ingaphezulu kunangaphambili isisiseko sempumelelo yethu njengenkampani ephakathi kumazwe ngamazwe.
