Sorry for asking a few additional Questions - Yes, I remember having the FRA Doccuments somewhere but for us here in Switzerland they simply do not apply at all - that the above two posts raised in my head:
- Why is it a requirement to remove the tubes after the "boiler time" is over? If they are still OK why not leave them in?
- Are Tubes in the USA generally welded in or is there no requirement on this in the FRA rules?
- Why remove staybolts if they are not proven to been broken? No reason, is there?
Sorry for asking more questions.
Kevin, IMHO tube life has exired as soon as one starts to leak... Not earlier. -> But I know the FRA states someting else.
Very best Regards,
