glueing up 6" sec 80 pvc

[HVAC HAWK]

i have a job coming up and it has 6" sec 80 PVC pipe for a cooling tower and 80 dreg water .
i do not remember if i ever glued up 6" sec 80 pipe before .
i think i need a thin set glue so it is easer to get the pipe together ?

do you think i need a pulling type tool to help get the pipe together ?
i,m about 6' 4" and about 285 lb :eek: and my boss does not think i can pull the fittings together .:rolleyes: ;)

I remember doing some 8" Sch 80 years ago during construction of Harrah's Casino in 1981. It was early March and we were outside working on the fountain. At that time of year daytime temps average in the 30's.

We (two of us) used winter glue made for low temperatures and had a tough time making the joints up as I remember. We rigged two come-a-longs (for an even pull) and some straps to get the stuff together. We were working in the mud behind sheet piling holding back 4 feet of ocean water, with a mud sucker running full bore to try and keep it somewhat dry. I couldn't wait for that piece of the job to finish.

We also had a number of bends to make in the bank of four lines running from the underground pump house to the fountain. Ever try bending 20 foot lengths of 8" Sch 80 outside in 30-some degree weather?

is there a tool to pull together large dia PVC pipe ?

[Bob D.]

Not that I know of, but I have not worked that area of the trade for many years. I can tell you that trying to get everything ready to glue up those 8" joints and pull it together quickly was a PITA the first couple times. Once we got everything adjusted and choreographed so there was no wasted motion it went fairly smooth. You might find you need to keep the clamping pressure on for a few minutes to ensure it doesn't pop out. You could also use a couple riser clamps in place of the nylon slings.

Solvent welding 6 schedule 80 is definantly a two man job. Be sure to have large cans of solvent and primer and get the large brushes. Be sure to use a lot of solvent to help ensure a seal and to provide viscosity for sliding the joints together. Put a bevel on all of your cuts. There will be spots where its easy enough for one man to handle but there will be many when you need a third hand. The weight of the pipe really requires two men to handle it properly anyway.


Bob,

My opinion is the fastest way is to use three guys. One is the glue guy (using a large roller and a bucket of glue, keeping in mind that you cannot over-glue a PVC joint), the second guy is on alignment (holding the pipe in position and centering it in the hub after glue application), and the come-a-long man (cranking the come-along down).

You need two choakers and a come-a-long for equipment.

It can be done with a plumber and helper, but is far less efficient.

[Bob D.]

You both added many pointers that I forgot about. Like I said its been a while since I messed with this stuff. I spend my time now-a-days working on instrumentation or planning and scheduling work for others to do, and the work is not out there in the mud anymore, but has its own unique set of problems and hazards.

Sometimes a little mud is not so bad :)

there is actually a tool out there that is designed for pulling the pipe together. it is used on the the hub style pipe with rubber bushings.

ridgid makes a #228 soil pipe assembly tool . it should work fine on plastic, since it has 2 chain type vices to hold onto the pipe and fitting.

sort of like doing socket fusion gas pipe on 2'' by yourself.
1 slip and you're toast:eek: that's why i use "butt" fusion.:D

no butt crack jokes.:rolleyes:

thanks

i used the soil pipe tool before doing cast iron but did not know that i can use it on PVC .

i like the idea of the riser clamps to get a hold of the pipe.

i know there is different types of glue I'm in a heated building what type do you recommend ?

[PLUMBER RICK]

slow setting grey glue would be my choice. check on the can for the specs. a fast setting glue is too hot to work with on this size of pipe.

"no butt crack jokes"

Now do you really think someone around here would crack a butt joke?

Maybe Lorax being his good humored self?

Naw, he's too busy working on that new crib I'll bet.

In my opinion, the Ridgid #228 is not a good option for 6" PVC, because it is designed for "Ty-Seal" type joints (rubber hub type cast iron). Using this tool will provide the problem of not allowing enough glueing room between the jaws.
