sealing up v bands
 

Couple questions. After welded some warping is to be expected. I have a flat bed belt sander which I used on the v bands and flanges. All of the flanges were easy except for the v bands due to being on long pipe and awkward to hold. Is there ways that I can make 100% sure that these will seal up? or should I have them go to a machine shop?

Could I use high temp gasket maker when I slap them together?

When I get them coated should I remove the coating thats on the v band mating surfaces aswell?

Thanks guys.

should have slow welded it with wet rags to keep from warping i also saw a right up on a web site about welding v bands, how bad are they post a pic

I always weld them bolted together super tight. Even if you need an extra one just to weld with. If you mill it down it probably won't seal.

they aren't obvious. Even when matched up to the other side. Theres just slight rocking in them. I welded them in 1/4 sections across from eachother aswell...

everythings welded lol so I need a way to ------- seal these bitches up.

how much seperation is there few mm then you might be able to just mate them extra tight when clamped

Re: sealing up v bands
 

yea a couple mm. I'm kinda stressed about this now. Fuuuuck.

cap a end with plastic and a duck tape mate the vbands together tighten like hell and fill with water to see if it leaks

Re: sealing up v bands
 

I will try. do you think a machine shop could get them flat?

if you machine any thing it will never seal, next time weld alittle then dunk in a bucket of water, not cold water either
