Well, after 2 days of putting a bevel on 1.5" sch40 ss by hand, I am looking for a tool to do this and make my life easier. After cleaning and beveling about 20 side of pipe, I was having trouble welding. My hand torch hand was shaking all over the place. I was using a hand grinder with a sanding flaper disc wheel.

Anyway, what tool would you guys recommend for me to put a bevel on the end of piping?

Regards,
Justin

 

its not mine i got the pic off the web. i dont have my camera on me, but you get the idea.

 

lol yea that's what I used to bevel mine. The pipe gets hot but it's better than using a grinder.

 

Justin,
I use a large disc sander but a small 12" one would do the trick.

Could you guys post links to good models/brands to look at?

Regards,
Justin

 

i feel justin on this as well

 

I think a 5" Mini grinder is best for beveling pipe under 6". With a 1/4" thick disk lay it flat on the pipe while holding it at the angle of the bevel while moving back and forth in a faning motion. pice of cake.

 

thats what i do. Roll the pipe on teh table back and forth while holding the grinder on the edge. i have no problems beveling pipe.

dito. I usually put it vertical in a vice and use my 4.5" angle grinder and go around it.

 

they make pipe beveling machines but they are $$$ ive looked in to them but using a carbide insert and build special fixture you can build one your self for a few hundred bucks

 

how much are yall beveling the pipe? the piping i brought form ace stainless comes beveled, does it need to be beveled more?

 

Nah, the bevel is fine. We are talking about beveling after a cut.

the bigger the better.

 

yeah get a stand up grinder with lots of power.

u will bog that **** down

 

i use my belt sander and a 40 grit disk. takes 4 secs

my sander has a 52.5x4 belt and a verticle circular disc.

i use the disc. cmpared to the bench grinder its a walk in the park.

 

This is what I use, with a custom made zirconia belt. It takes me about 5 seconds to bevel each side of sch 10 / 40.

 

I am hardcore use my rigid 4.5" angle grinder with 40 grit zerconiam flap disc
The disc last about 100-150 bevels each and I knock out each bevel in about 10 seconds, the discs dont heat up the metal and dont leave any burrs at all eather so there is no clean up when finished

Belt sander....works good. Far easier, far quicker, with far more consistent results than the bench grinder approach.

 

The problem for me using the angle grinder to make a bevel is that it fatigues the muscles in my wrist and I have trouble being steady when welding after beveling 20 ends.

I'm going to look into a belt sander. That sounds good to me.

What brand belt sander is that? Looks really nice

Ideally, I would buy a horizontal belt sander big enough to surface my head flanges after I've welded up the turbo manifolds.

horizontal belt sander is not the right tool to surface flange with, use a surface grinder. they can be had for less than $500 at a auction

that's actually what I use.. (the 'disk sander')..

I have a 10" disk sanding attachment for my lathe and built a table for it. 40 grit is surprisingly smooth and it doesnt roll the edges over as bad as my bench grinder.

The bonus to having a disk/belt sander is that you can tweak and square the angles on the els easily and accurately. With a fresh sanding disk you can take 1/8" off in a decent amount of time but you better have a bucket of water around to dip the 'pipe' in every so often.

It's the right tool if you want to screw up a head flange in a hurry.

can you elaborate on this please?

 

12" disc sander with a 1/2hp 220 motor. Nothing slows it down.

ok.

A flange may become warped after the welding process.

A belt sander is not the right tool for surfacing a head flange (making the head flange 'flat' so it mates with the head without leaking). A belt sander is meant for sanding.. after sanding the surface may look flat but I'll bet my left nut that it wont be.

A mill and a 'surface grinder' are what you should use to make surfaces flat and true. A surface grinder is the best method (but way overboard) and a mill does the job perfectly and is probably used in the factory.

If your manifold flange is not perfectly flat, pay a machine shop to "mill it". Dont be a douchebag and tighten is flat to the head - this can only increase your chances of getting a crack.
