Schedule 40 316 pipe for exhaust elbow

[JSYmartini]

I've been asked to replace someone's rotten exhaust elbow with a new stainless one.

I can order a 2.5" dia, long elbow no problem, quite cheap actually:

The trouble is, the old elbow has been extended by 20mm at one end and about 50mm at the other. So I need an off cut of straight pipe to do this but it's £85 a metre, plus loads of postage to Jersey :ambivalence:

Does anyone have any bits lying around or know someone who does? A fabricator who works with this kind of thing and has a scrap bin full of bits?

I can't get the flanges profile cut because the set up costs are too much for one off's so they have to be hand made (can't find any suitable universal weld on flanges on the net surprisingly) - this could be the world's most expensive elbow if I don't reign the costs in a bit!

Any help/advice most welcome

Have you looked at ASAP? They do flanges and other bits for diy exhausts.

Thanks, yes but nothing of any use to me there.

I recently had a few bits laser cut in stainless by these guys; http://www.lasermaster.co.uk/easy-order and they could probably do the flanges at reasonable prices

I can make you a couple of pieces from some off-cuts of 316 bar. but just to clarify sizes, you want 73 O.D by 62.7 I.D, 20 long and 50 long?

There was an article by skipper stu in PBO magazine a while ago on a DIY exhaust. You can search the archive on the website. (if it works!)

Metals4u were very helpful when I needed a short length of thick-walled 1 inch tube, sold me a piece about 8 inches long. Might be worth a call/email.

Have a look at

A 2" barrel nipple may have just enough to make up the length required.
