I-ASTM A213 T9/T11/T22/T91 Ingxubevange kunye neTubhing eStainless yeeBoilers kunye nabaTshintshiseli boBubushushu

Apho ezi ityhubhu zisebenza ngcono (kwaye kutheni i-stainless ihlala iphumelela)

Iibhoyili zamandla, ii-HRSG, izifudumezi ze-petrochemical, kunye ne-compact heat exchangers zonke zixhomekeke kwi-ASTM A213 / SA213 iityhubhu ezingenamthungo. Xa i-chloride-izala i-condensate, imijikelo ehlala imanzi-yokoma, okanye iimfuno zococeko eziluqilima etafileni,iaustenitic amabakala angenanto (uthotho lweTP)ithanda ukodlula iChrome-amabanga e-moly ferritic enkosi kumhlwa jikelele kunye nokunganyangeki komngxuma, ukugqiba okugudileyo kwangaphakathi, kunye nokucoca lula. -ubushushu obuphezulu, inkonzo eyomileyo enomda ongqongqo wokuchwechwela isagciniweT-amabangaekudlalweni-ingakumbi kwizifudumezi kunye neebhanki zokufudumeza.

Iimeko eziqhelekileyo zokusetyenziswa:

I-Stainless (TP304/304H, TP316L/316H, TP321/321H, TP347/347H): izitshintshi zobushushu, iinyanda zecondenser, isondlo{8}}izifudumezi zamanzi, ukudleka okanye umjikelo{9}}inkonzo emanzi.

A2:I-T11 sisiseko seqondo lobushushu eliphakathi, i-T22 yongeza umda we-creep kumacandelo ashushu, kwaye i-T91 isetyenziselwa owona -ubushushu bobushushu obuphezulu/umsebenzi wokufudumeza.

Q3: Loluphi uhlolo kunye namaxwebhu ekufuneka ndiwacele kwi-ASTM A213/SA213 ityhubhu?
A3:Cela i-hydrotest okanye uvavanyo lombane lwe-NDE, i-100% eddy yangoku/UT ukuba iyafuneka, i-PMI, kunye ne-EN epheleleyo 10204 3.1 ye-MTC enobushushu{2}}iirekhodi zonyango.
