Title: Pipe coping machine
Post by och on 07/27/22 at 06:15:49
I know a lot of us here work with metal machinery, I thought I'd share this, its an absolutely awesome machine. Baleigh TN800

Fine piece of equipment. In my stumbling around the school of YouTube I ran across this guy. Some of us here may well find ourselves in need of making such connections in pipe and this guy makes it look easy. Yeah, but we Know how deceptive that kinda stuff usually is. Give him a few views and likes..

This is a T,but he does a 45 in another vidya.

It's always fun watching machinery making stuff.

There is actually a simpler way of doing coping with a grinder, but the beauty of having the machine is the ability to make perfect shape cope, to make easier welding. I have a job right now with 75 lengths of 2" schedule 40 pipe, there are at least 600 T connections. Bought the machine just of the job.

You have reason to buy that! Onezee Twozee s Naah. Six HunDred? Yeah!
What is the wall thickness? On pipe, the diameter is the inside diameter, right?
What kinda lengths are you working with?
Went and looked for the answers.

Okay, took a while, finally got it..



https://neelconsteel.com/schedule-40-pipe-tables-technical-dimensions-thickness.html

How much training does it take to make the machine do that?
How is the pipe held up? Is there a certain length of pipe that it just Can't deal with?
I always wanted to be a machinest,finally got a job and was just not wurfahoot at it. I did learn to sharpen drill bits, which I have used a lot more in life than algebra, which they Told me I would need, as justification for demanding I learn it.

And I'm guessing that machine will cut the saddle for any angle, Izzat right?
What are you building?
I'm Totally interested,
Hopefully you post a few pictures.

Not to nit pick, but after a career in metal fabrication management/quality assurance, I have to speak up to help educate.  There is a difference between PIPE and TUBING.

PIPE
This material is made for the transfer or liquid or gas.  It is rated and sized for the inside diameter, and pressure it can withhold.  Wall thickness and material type are the biggest determining factors in the rating.

TUBING
This material is designed for structural applications.  As such, it is available in many more shapes and sizes than pipe (which is always round).  For round tubing, it is measured by outside diameter, and wall thickness.  It is available in an assortment of material types from steel, alloy, stainless, and aluminum to name a few.  It is also available in seamless, or DOM (drawn over mandrel).  Size, wall thickness, material type, and shape determine the structural qualities of tubing.

Too many people refer to tube as "pipe".  If you buy a pipe bender, the die sizes will be much different than a tube bender.  This is due to pipe not being sized for it's outside diameter, and tube is.  When looking into equipment to work these types of material, know the difference.  A pipe bender will kink tubing.  A tube bender will not as the dies are properly sized to closely fit the outside diameter.

In that video the guy was coping TUBING, not PIPE.

Doing roof railing on a commercial project, it is going to be all welded construction and with powder coat finish. I'll certainly post photos when I am done.

The machine can set any angle, so I can do connections at any angle. In the past I used grinder to do it, but this project is far too large, and it was well worth to invest in the machine.

This particular job is 2" schedule 40 pipe with ~2-3/8" outside diameter, pipe always goes by inside diameter. In most cases, guardrails are 1-1/4" schedule 40 pipe with ~1-5/8" outside diameter, but this needed extra strength due to increased height.

This particular project is actually pipe, 2" (I.D.) schedule 40 with ~2-3/8" outside diameter.

It just happens that in the handrail industry we mostly work with pipe, not tube. I buy a lot of parts from Wagner and Julius Blum, most common parts such as elbows, sleeves, end caps, base plates, etc are made for pipe, although there is plenty of stuff for tubes as well.

Thank you for this. Actually a pipe/tube bender is on my radar, waiting for a project to come in that will justify the purchase. Can you elaborate a little further, I've never worked with one, but I thought the machine is the machine, its the dies/rollers that matter? I'd love to get a machine that is able to do both round pipe and tube, as well as square/rectangular profiles.

P.S. - the learning curve on this machine is an hour, very simple to figure out. I am working with different lengths pipes, but there is a wise that holds the pipe in place, and you can get a stand to assist with longer lengths.

I have seen a lot of style of tube benders, and pipe benders.  Not saying they don't exist, but I have never seen a bender that will do both.  The bender would have to be able to accept the right size dies for the material you are bending.  Different style benders have different limitations.  The dies are everything when it comes to bending.  They have to fit the OD of the material being bent.  Since pipe and tube have different OD's, they would require different dies to bend them properly.  The bender I picked up when building my baja came with one set of dies.  Getting a different size and bend radius die set was almost as much as the bender itself.  As I said, the dies are everything when it comes to bending.  You can get a bender that will do square or rectangular material as well, but the die design and cost goes waaaay up.  

This is the bender I got.  The die set is for 1.5" OD tube and has a 7" CL bend radius.  To change either of these dimensions you have to have a different die set.  One of the limitations with this style is you can only get around 135-140 degrees of bend before the material contacts the frame of the bender.  It will not do 180 degree bends.  Two 90's, cut and weld.  Also since it uses a bottle jack, it is a bit laborious.  Lots of pumping.

The learning curve when bending pipe or tube is a bit more than coping.  Let's say you want to build a roll cage in your car.  You calculate all the lengths of your design, and go to buy the raw material.  Steel tube comes in 20' lengths.  "Learning curve" will cause you to waste 20-30 percent.  Gotta break a few eggs to make an omelet!

Oh, I'm pretty good with calculating materials, I first model everything in CAD/solidworks before fabricating.

That's a manual bender, I would be looking into an industrial grade bender that can do 1"-3" diameter and with enough power to do schedule 40 stainless.
