I am dealing with pig launcher facility after the metering skid for 28" pipeline.

There are multiple pig launchers & we wanting to locate our pig Launchers in such a way that end closure (barrel sides) to face away from the plant facility. For this we are intending to have 2 90 deg 5D bends immediately after the pig launcher.

Do you think this is a problem from pig movement point of view?

Can we have a launcher arrangement in such a way that we can launch multiple pigs to multiple pipelines...that means one launcher multiple piggabele lines? I am not sure is this possible or not but just asking as I am not getting enough information by googling.

I am new for pipeline engineering so these questions. Pls help

I don't know what your pipeline configuration is down stream of your launcher is so I can't make a "good" comment on the use of the two 90Deg 5R Ell.s you are speaking of. I would suggest looking at trying to use 45Deg Ell.s where possible, but in general 5R 90Deg.s should work. ...A mult-pipeline launcher is possible with the use of "pig diverters", but you need to think about doing this as pairs of pipelines. "Cold turkey" that probably doesn't make sense, but check out this link and you should get the idea: http://www.youtube.com/watch?v=-NNO56CY1HY

I am being asked (by my boss) to put a S-O-L onto an ecc reducer on the flat side. I personally have never done this. I don't think it is good connection or practice but I was wondering if anybody has ever done this before?

I have done this many, many times.
If you can do it on straight pipe why would you not be able to do it on a Ecc. Reducer?
Do it once and Do it Right
