What method should I use to in-line detect 10 ppm level of oil in my sewer effluent into open water? As usual space (resting time) is limited, so layer detection is not appropriate. On detection I would close the discharge valve. thanks in advance.

Thanks Jim. The flowserve thing looks workable, some concern about the remaining dripping after sampling. The second, I recognised but I do not want to rely on the small seal for tightning.... Anybody with experience in using the flowserve type of sampler?

Introduce improvement items for your staff to come up with. Like operational and safety improvements/enhancements, record them, set up improvement plans, track the progress, award the groups (both thinkers and enablers), and feed back the outcome to MD. Precise follow-up is very hard, but it...

I am looking for a solution to sample oil (300ml), recirculating over a pump back into its own tank. A simple tap can not be used as "bottom" tankvalve, as it is not reliable. We do have experience with a bypass stream but is a messy operation (maybe not the right type of bypass (or...

No gage plate was used to my knowledge. I will certainly add this to our engineering standards before commisioning of any piggable piping.

Very well, but first I need to know where the location(s) are. Is a gauging plate a known "best practise" as prover in welded piping?

During construction a welded seam is now obstructing the pig for the weld was too hot. Are there any ways that a type of pigs can smoothen the internal pipe surface? As there is welding drop I assume that a steel brush pig is not sufficient...
