Geez. Going back a bit in time to my water treatment days here but I’ll give it a go. It’s been over 17 years since I’ve worked with cement lined pipe.

CM lining is generally used for potable water. the pipe itself is ductile iron. The size ranges from 300mm to 1600m dia. depending on the manufacturer. Biwater and Stanton were the main 2 manufacturers at the time.

Just had a route around my desk for my Biwater book which is (or was) the bible for all ductile iron pipe. It must be at home somewhere. I do have some disks with CL DI pipe and fittings on them though if you’re stuck.

Cement lined pipes are never flanged from memory so when connecting valves etc you would use a Viking Johnson flange adaptor.

When designing make sure you protect against surge as this could cause the joints to pull apart.

I’ll have to get back to you after I get home and find my biwater book.

in the meantime I hope this helps,
J
