Hi Steve,

I am aware of Pfaudler but they are strictly vessel people.

I came across Duker on a net search and am following up with their German branch.

I can remember Greenline wanting everything flanged but in the end it was too time consuming measuring and getting specials flown out. So we attacked it by having plan ended pipe and using the Victaulic joint that grips the outside of the pipe. Also the gasket used was their firesafe type, that filled in the gap between the pipe ends, to limit corrosion at that point.

Cutting the pipe was quite easy using a diamond bladed saw real slow with water as a cutting media.

Being a Sch 40 outer pipe we were able to design to ANSI B31.3.

Cheers

Geoff Stone
