A pipe-bulging kit. http://www.roman-road.co.uk/temp/DSC00164.JPG the tubular bit (left, in 2 parts, as it happens) fits over the pipe, leaving about 5mm out the tapered end, the mandrel goes in the end of the pipe, then the lot goes in the vice and gets tightened carefully, 'til it bulges as shown at right. The point of this should be obvious. an it's an "interesting" exercise grinding the tool to turn the reverse chamfer on the mandrel, doesn't show that clearly in the picture but it's this shape: _____ \ | |¯¯¯¯¯¯¯ | | | |_______ | / | ¯¯¯¯¯  SignatureAustin Shackles. www.ddol-las.net my opinions are just that Travel The Galaxy!

The one I have only goes up to 8mm. I'm not sure it'd cope with 15mm anyway, the vice has a good bit more pressure. Also the one I have tends to distort the tube ('cos it's a split clamp), whereas my hollow bit is bored the correct size.

Ive not checked (its buried in the garage) but according to the web it goes to 5/8". It does leave a ribbed pattern on the pipe tho :( The mandrel bits are quite cheap as spares, to save the interesting grinding. (I snapped several of the tiny ones doing an awkward in situ repair...) Didnt mean to offend, just offer a shortcut if you weren't aware of it.
