Intelligent pipeline pig.

It's me again.
Please advise me on the intelligent pipeline pig overall dimensions. I've searched nearly every manufacturer and I cannot find a reliable source. Please direct me to it.
Thanks in advance.

There is nothing standard about smart pig length. They vary by manufacturer, by model, and by parameters collected. You just need to contact the company providing the services and get the dimensions on a pig that will return the data set you are looking for.

But as a "for instance", the technical spec sheet of NDT Systems & Services of Germany and Canada says their ultrasonic pig is 4 metres long.

Nigel,
When you say 4 meters long, what diameter are you talking about? A 4-inch smart pig would be unlikely to be that long, but a 30-inch would be unlikely to be that short.

As zdas says, the sizes can be all over the map. 4 meters might be a little one. Check with the service providers themselves.

for pig dimensions pipe welbow radius puts some limitations depending on test operator pigs

One vendor told me that his smart pig could not tolerate any pipeline bends tighter than 40D radius. Since you typically buy hot bends around 8D radius and even field bends tend to be around 25D he wasn't running many of his pigs in real service.

Bottom line is to pick a pig based on their having the capability to collect the data you are particularly interested in, have the ability to come to your location, and have equipment that will deal successfully with the issues that your line represents. Hook up with a vendor early in the process.

Seems like some can do a 5D now, since they started segmenting them, but better to check.
