speaking of varying editions of the codes can anyone say whether there is a time period in the transition from an old code to an updated one or can we just roll along using the old one ignoring the fact that newer editions often have serious changes – like 1554?

eg im reviewing documents that refer to 1210-1987 and 1554-1994.

Hi Conor

If you look through the 1554 standards (they are a set of 7) they will give you set of pre-qualified parameters and guidelines to follow.

Someone with a Certificate 10  or a welding inspector for example can do the procedures and show you what is required. The WTIA has a set of guidelines as well that one can follow especially where pre heat and post weld heat treatment is concerned.

Yes the weld procedures are required to comply with the relevent standard. If your stuck Im sure there are a few of us here that can help out

Is there no one available in your company able to carry this out?

Cheers

hi

there is a clause regarding consumables in 1554.1 – 4.6.1.3 which mentions a minimum of 300 c for inter run temperatures but this is for designated seismic service.

i cant see that using this as a guide would be detrimental.

cheers
