Need help making a connection.

OK engineering guys

My problem. Getting from a 28mm copper pipe onto a 1 Inch BSP thread.

I have a 28mm copper pipe which must connect on to a pipe riser.

The pipe riser is 76mm teeing off to a 28mm X 1" BSP male threaded adaptor. I need to join the 28mm copper with the 1" BSP thread. Now I do have a 1" BSP Female x 28mm coupling but we are buggered for space. I am needing a flexible solution so I can mount my tee lower down but keep my horizontal distance about the same. Problem is I can't seem to find a flexible connector that is 28mm x 1" Female.

Please help.

Try Macmaster Carr or MSC Direct. Whats the application I assume it's for water what ever pipe you use is compatible. If it's just water you can use PVC and flex tubing. Try not to mix units pick one it will save a lot of headache.

It's for a chilled water system. HVAC. Thing is the thing will be off the coast of Australia for a year.

Any way seems we have found a solution.

Make sure you have enough cathodic protection copper won't last long in a salt water environment. Stainless and brass is a must. Let me know if need more help I have a degree in Ocean Engineering.

Well the riser pipes are carbon steel. Client requirement. go figure
compression fittings onto the copper are brass. Told this should be ok.

They are using copper for the 4" black waste....be a lovely shade of green in a few weeks.

Got to love contract requirements. The carbon steel will be a nice color red before it even gets on location if there is no protection. Be real careful when mixing metals, think galvanic series the brass will cause the copper to corode first and will speed up the process. Be sure to protect the threads with anti-seize or tef-gel or it will never com off.

I'm assuming your making a maned offshore platform have fun.

I worked on a project for the navy that required the aluminum to be anodized on an AUV we had colliflower spots all over the place.
