How to clamp down pipes

[nate379]

Guys, I had to relocate the gas line running to my boiler since it was in the way of my soon to be placed water softner. I'm not sure what the correct way to clamp the pipe to the wall would be.

The pipe I have is 1" black pipe.

What I have used in the past are "C" type straps and then cut a spacer out of wood to put behind it. In this case, I have about 3/4" space between the wall and the pipe.

Am I using the correct thing?

Those should work fine. Plumbers typically use metal strap with a nail.

I can't see how much space between the wall and your pipe. A two hole strap into a board screwed into the wall like you said works well.

If you have more of a stand off you can use these

with:

and a piece of threaded rod cut to length. Might be too close for that in your case....

I would use a piece of the thin unistrut, its about 3/4in thick, with the appropriate size pipe brackets for it.

That is what I have for the rest of my pipes... just $20 for a 10 ft stick kinda ***** when I need maybe 2 feet though.

You already had it just fine. Make sure and nail them into studs and you will be set. Screw all that high dollar stuff, you are wasting a bunch of money you do not need to!

3/4" (2nd to last line in my thread)

yeah, but at the same time its handy to have around. I had to cantelever a shop light off a beam to light up a workbench, but hold the light under the garage door track so the door would open over where the light was. Couple scraps of unistrut and I was done. I wish the home centers would sell like 4ft pieces of it.

I ended up buying some unistrut.
You can't see in the pic but all my heat pipe are held with that too. I need to cut some pipes and move them around to get the water softner in so I will need a few pieces.

4ft stick would have been perfect. I needed about 2ft of 3/4" and maybe 3ft of 1.5". Had to spend almost $40 on 2 10 ft sticks.

Unistrut (or B-Line, etc.) is great stuff, though a bit pricey and maybe overkill for your application. It does allow some flexibility in adjusting the location of the pipe, but the great thing is if you are going to locate additional pipes in the future, half the work is already done.

Plus they have the correct fittings for almost any pipe or conduit, and their General Engineering Catalog (designed by and written by Engineers by the way ) has all the installation data including the structural qualities, finish details, etc. Makes a good reference manual for anyone doing equipment installs.

you could just stack 2pc of 3/4 and return the 1-1/2in (but then you wouldnt have the leftover )

 

[nate379]

Yeah I thought about it, but it's sorta hack IMO. I might have to stack 1.5" for 3" spacing in a spot or two as well.

The clamps I am using are listed for use on Rigid, IMC pipe and EMT so I hope that is the right stuff. It fits fine.

I can't fine any copper ones to match everything used on my water and heat pipes though. I am guessing copper pipe with galv clamp isn't a good idea?

You're right. That could/would lead to galvanic corrosion. Use copper or the plastic coated pipe clamps designated for copper pipe applications.

what is typically done, is a couple layers of pipe wrap tape is wrapped around the copper pipe where the clamp contacts it.

You want Mineralac, I welded this to a conduit but there is a hole thru it. I couldn't make it without a box of each of the common sizes and type of clamps, make dozens, hundreds of things from them.

+1 on the strut!!! This stuff is awesome. you can build bridges with this stuff. Trust me. There wont be an inch of this stuff that will go to waste. Use your imagination for the rest. If you have some buddies that work construction you can probably get some cut offs for free. Or dig around on a commercial construction job site dumpster.

 

[nate379]

I could have probably gotten some from a guy I know but he's got other things to worry about right now so I didn't want to bug him about it. I'm sure I'll find a use for it or I can sell the remaining stuff for a few $$s on Craig's List.

I ripped it apart last night though. It was bugging me to have to do the 45* to get it close to the wall so I pulled out all the fire caulking, thought maybe I'd have to cut some rock to get a wrench in there, but I was able to get the pipe off the elbow in the wall so now the 90* is close to the wall and no 45s.

Been working on it 30 mins here and there, between work and other stuff going on I haven't had too much time.

For a gas pipe, I would have just spaced off the wall with a 1X3 and strap clamped it. But that's just me.
