Can you freeze mdpe pipe?

[MOSSEP]

Hi,

I have a 32mm mdpe pipe in a warehouse that I need to re-route. We can't shut the supply off so I wanted to freeze it to work on it. Is an electric pipe freezer likely to damage the pipe by making it too cold / brittle? Don't want to get halfway through the job and find it splits or cracks on me!

thanks

Whose paying £1500 for freezer can rent them for tuppence borrow them for less,

When working on site temp water supplies always freeze in the winter months we use to defrost the mdpe with blow torches.

It's pretty durable stuff UV not no good for it from memory

Yep. But a couple of pieces of wood and a G clamp normally does the trick, doesn't it?

not me (although I do have one), just pointing out the difference in costs to do the same thing.

Ive already got a commercial size pipe freezer, I was just unsure if it would actually damage the MDPE itself. It gets incredibly cold and Im not sure what the safe minimum temperature rating of the material is. Don't want to stick the freezer on and then find it cracks or something daft like that.

cant you bend it over which effectively squeezes it off. cut a stop valve in after the kink, unfold the pipe and voila you can work at your leisure with an isolated supply.

Agree with ray I use 2 22mm guides and 2 6 inch G clamps works fine but am still on lookout for proper clamp saw one on ebay and told youngest daughter who wanted to get me a birthday present.Im not buying you that big rusty looking thing she said,Well she did ask what I wanted..never got it prob got more socks and pants to go with the rest..brum
