Mafumbo ghakufumbika

Q1: Kasi ningasankha wuli pakati pa magulu gha TP ghambura zimbiri na magulu gha chrome -moly T pasi pa ASTM A213 / SA213?
A1:Gwiliskirani nchito ma grade gha TP pa vyakunyeŵa/vyakufipirwa panji vyakukhumbikwa vya uteŵeti wa chloride na kutozga; gwiriskani ntchito magulu gha T para kwauma chomene -nkhongono yakukhwaŵa yakutentha ndiyo yikupangiska chomene.

Q2: Kasi pali mphambano wuli pakati pa SA213 T11, T22, na T91 tubing?
A2:T11 ndiyo mzere wakuyamba wa kutentha kwapakati, T22 wakusazgapo mphaka ya kukhwaŵa ku vigaŵa vyakutentha, ndipo T91 wakugwiriskirika nchito pa mulimo wa superheater / reheater wakutentha chomene -.

Q3: Kasi ni vichi ivyo nkhwenera kupempha na vikalata vya ASTM A213 / SA213 tubing?
A3:Pemphani hydrotest panji NDE magesi mayeso, 100% eddy sono / UT usange vikukhumbikwa, PMI, na EN yakukwana 10204 3.1 MTC na kutentha - marekodi ghakuchizga.
