Fester's Easy Flange

These are heavy duty flanges to attach 2 inch copper pipe (2-1/8" OD) to your sanke keg.
Each weigh about 1/2 kilo. Some of you may remember my post on HD in the Easy Flange thread.
Each started life as a cast copper donut shape and then machined to specs. The profile of the flare part of the flange is exactly like that of a standard 2" SS sanke flange because I simply copied it. Your pipe will bottom out against a shoulder about 3/4 of an inch below the top surface giving you good support for your column.
The metal is 99% copper and 1% tin. This was necessary because casting pure copper led to brittle and porous castings that caused too many rejects after machining.
The grove for the gasket is exactly like that found on the SS sanke flange. Again I just copied it.

I am living in China now so I can ship world wide, I assume. I have about 100 of these ready and the cost is $27 USD each plus shipping. I'll be taking a 2 week vacation in Hong Kong next week so it will be about 3 weeks or so before i can ship these to you. I can accept PayPal and I don't know the cost of shipping. After I sell a few I'll have a better idea about that.

I have other ideas in the works but no progress yet on actual finished product. The next project will be a spun metal reducer that will fit the flange. Sort of an instant pot still for the sanke keg. Or maybe a lyne arm?

2" to 1/2"

Nice. I gather the pipe fits INSIDE the flange?

[Fester]

.... the pipe fits INSIDE the flange?

Yes Punkin. Its the strongest way. I tried to pattern it after any true copper fitting. But the wall thickness is a little thicker than a standard forged fitting.

The Outside Diameter of copper pipe stays the same accross the different schedules, or wall thicknessess, of the pipe. I don't think this fitting will work with DWV (thin walled Drain Waste and Vent) type pipe. I only know USA copper pipe so it may be different to you metric folks.

Welcome back Fester, i thought we'd lost you and then you come back bearing gifts.

They look really good

[Fester]

Thanks Aces High,

I've been busy relaxing for a while but now its time to have a vacation.

This relaxing all the time is more work than I thought it would be.

Wish you had 3" available.

Nice work!

Hi Mr. Me, its great to see you again,

I had a long talk with myself about producing different sizes. 1/2" - 4". But for now I've standardized on 2". Gots some ideas for an inline bubbler plate section, an onion ball and some other goodies and I want all of the pieces to play well together. Its slow going to add a product and I'm sure to be asking you folks' opinion before I commit the money to producing them.

Personally, I'd love to have a few 1/2 inchers to connect my condenser without needing to use a wrench. Tri clover fittings are so cool I want to use them everywhere.

Nice work!

How many do you want?

I owe you a favour, would be happy to source some stainless ones that fit 3"pipe in the id and ship em to you for the cost of it.

Send me a pm.

Nice work!

Have you seen these? Might need to modify them a bit to suit your tube size, but the 2" Type S version has the same inner diameter as the outer diameter of our metric equivalent tube - 54mm.

An onion ball would be awsome fester. Very pretty flanges btw.

Nicely done Fester. Good to see that you are around.

[Fester]

Thanks Kiwi and Rebbel_Yell,

My idea is to make an onion ball about 5 or 6 inches in diameter with Tri Clover fittings in the middle to open it up. Then it could also serve as a gin ball, perhaps. Also, the onion would modified to be an inline bubbler plate or small thumper. Lots of drawings but nothing in CAD yet.

Hmm ok. I'd be wanting a bigger one personally. Something to go on a 4" pot column. Openable for using as a gin basket would be the mutt's nuts.

2 x S/S bowls & a drum head clamp will get you there Kiwi.

[kiwi]

You're an ideas man harry.

But no, I want something copper, I want the ball at the bottom of a tall column a la Glenmorangie. And (being honest now) because it will be pretty.
