[Steam-engine] Boiler Inspections

Tue Dec 11 07:40:46 PST 2007

Well.... You Probably Don't want to hear from me... :) Here in Wisconsin we pretty much alternate between a Internal and a Hydro Every other year with a UT Every 5 years... There is rumor some inspectors are doing an In Service inspection also... At Least I know of one that has done some.

Problem we have is in the safty factors.... Some inspectors require 5... Some 4, Some will allow 4 with Proof of at least 55,000 Tensil strength.... I know of 2 guys that had to cut a piece out  and have it tested. Our inspectors will Not do UT... You have to have that done by somebody else...

The real Kicker is that so far ASME Boilers aren't required to UT at All... My Case was never UT'd for the state and was current untill July 2006. This was No Doubt a decision by someone that Didn't think that any ASME traction boilers were built.... Some engines are required to have 2 separate water feeds... While I see many at shows that only have one...????

Some of us are Kinda waiting on the "New Appendix C" which will put the Safety Factor and UT Issue in Black and White so we know where we stand....

So Far we have No Reciprocity but we are trying to get that changed....

I haven't had my engine inspected lately as I haven't taken it off the farm anyway....  Maybe if they get all the inconsistancies ironed out that could change.... ????Ken Majeski, Ellsworth Wis.
