    Tie-in on expansion loop

    "Depending on the design and operating conditions, there are likely to be areas on an 'expansion loop' which have little movement and low stresses, and may be just as safe to tie in there as at another location. " !! You sure not talking about the loop itself? Or are you really? Siddharth...

    pipe wall thickness

    greg211 why would you use 31.8 for manifold? I would use 31.3 for wall thickness and SIF's and use PD8010 for stress calculations. Siddharth These are my personal views/opinions and not of my employer's.

    Pipeline Bends- Tangent Lengths

    JT For a 'pulled bend' you need some straight length at both the ends for the bending machine to get hold of the piece. In general this length is specified as 500mm, I believe. regards Siddharth These are my personal views/opinions and not of my employer's.

    Offshore Pipeline Leak : Preservation Method

    4 month on and still 5 months more to go. and this is estimate. At what stage of the design life is the pipeline? As BigInch has said already this is not going to be cost effective anyways. Can the leaking bend be contained by two pigs from either sides? May be using some sort of rubber swell...
