I-ASTM-335 futhiSA-355MUkucaciswa Okujwayelekile Kwepayipi Lensimbi Engenamthungo Le-Ferritic Alloy-Steel Yesevisi Yezinga Lokushisa Eliphezulu.
Kungokwe-Boiler kanye Nekhodi Yemikhumbi Yokucindezela.

Ifomu le-oda kufanele lifake izinto ezilandelayo eziyi-11:
1. Ubuningi (izinyawo, amamitha noma inombolo yezinduku)
2. Igama lempahla (ipayipi lensimbi engenamthungo)
3. Amazinga (angu-16 esewonke: P1, P2, P22, P11, P22, P91)
4. Indlela yokukhiqiza (ukuqeda kushisa noma umdwebo obandayo)
5. Sebenzisa okukodwa kwalokhu kucaciswa okulandelayo: 1), i-NPS kanye nenombolo ye-serial yokuqina kodonga lwepayipi, 2), ububanzi bangaphandle nokuqina kodonga okuzisholo, 3), ububanzi obungaphandle nobukhulu obuncane bodonga, 4), ububanzi bangaphakathi kanye nokushuba kodonga okuzisholo , 5), ububanzi bangaphakathi kanye neziqondiso zokuhleleka kodonga obuncane
6. Ubude (buhlukaniswe ngobude obunqunyiwe nobude obunganqunyelwe)
7. Qeda ukucubungula.
8. Izidingo zokukhetha (ingcindezi yamanzi kanye nokuchezuka kwesisindo esivumelekile).
9. Imibiko yokuhlolwa edingekayo (bona i-A530).
10. Inombolo ejwayelekile.11Izidingo ezikhethekile nanoma yiziphi izimfuneko ezengeziwe ozikhethela zona.
Izinto zokwakha kanye nokukhiqiza
1. Amapayipi ensimbi okuthiwa angaqedwa noma adonswe ngokubanda, futhi athole ukwelashwa kokushisa kokugcina okudingekayo ngokwezinga.
2. P2 kanye P12 grade steel.Lawa mabanga amabili ensimbi kufanele enziwe kusetshenziswa inqubo yokuncibilikisa okusanhlamvu okumahhadla.Uma kunezidingo ezikhethekile zosayizi wokusanhlamvu noma inqubo yokukhishwa kwe-oxidation, kufanele kuvunyelwane ngazo umthengi nomkhiqizi wensimbi.
3. Ukwelashwa kokushisa
1. Ngaphandle kwensimbi yezinga le-PSC, P23, P91, P92, P122 kanye ne-P911 futhi njengoba kucacisiwe, wonke amabanga amapayipi okuzisholo azoshiswa kabusha futhi ahlinzekwe esimweni esifakwe i-annealed ngokugcwele, isothermal noma isimo esijwayelekile nesipholile.Uma kunikezwa esimweni esejwayelekile nesipholile, izinga lokushisa elincane lensimbi ye-P5, P5B, P9, P21 kanye ne-P22 yensimbi lizoba ngu-675°C.Izinga lokushisa elincane lensimbi yensimbi ye-P1, P2, P11, P12 kanye ne-P15 kufanele libe ngu-650 ℃.
2. Ukwelashwa kokugcina kokushisa kwensimbi yebanga le-P92 ne-P911 kufanele kube okujwayelekile okungenani okungu-1040 ℃ futhi kushise okungenani okungu-730 ℃.
