Biomass - Which insulated pipe?

[Bernt]

Duct tape on isover lagging. A roll of foil tape is the same price! !! Lol and makes the job look right

 

[farmerfred86]

dont panic... Foil tape has been used all over the foil backed pipe. But they also covered this external pipework joint with duct tape to protect from the sun for a few days before I could protect with boxing.

my outdoor pipe got covered in foil backed lagging , then wrapped in some super sticky hession type tape

 

[Bernt]

Probably used denso tape, dark green and gooey.

Flexenergy pipe cheaper than most and deal direct with you
and all sizes too .

 

[roadrunner13]

Any idea what they charge for say 75 mm single?

 

[Still Farming]

Long time since bought off them but look on net .
Think rep.customer support lady was called dot-I received good prices,and next day delivery and service and installed myself and still good years down the line.

 

[Bernt]

dont forget to hire a fusion welder specific to that type of pipe, no doubt will cost a fortune, i know the welders for yellow gas lines do!!

Nah-buy it correct length in 1st place ?

There is also cvp which is pretty good. At the end of the day it comes down to price with a lot of projects.
People always want a cheaper price so most the time it means using a cheaper less efficient product to win the job by cutting a few 1000 here and there.

Advice years ago by some was to put steel pipe inside a soil pipe and expand foam either ends ?
How primitive that idea was ???

I worked for a company two years ago and they cut up 30ft
Lengths to fit them in the skip... Sorry guys you probably didn't want to know that...

Don't burry it in the water table,, it would be better
Off on the surface!! Ha. But yes the deeper the better if its dry it's good. If you have uno.. (Two single pipes) put
The flow lower. If it's duo.. It's a bast@rd to connect a t.. But I like rehau for the jointing system..

To be honest I see rehau everware so it must be either good or good value. I remember it being said that you can get better pipe but it's payback is a lot longer so rehau I guess is middle of the road,, the ford of insulated pipe... I wouldn't be too worried about the sand as we used to track the diggers over it and beat it into submission around corners..

 

[frustratedfarmer]

I agree ref sand if it's going in to a good subsoil.

Uponor given v generous discounts to us which seem to be akin to rehau's better quality pipe.

My plumbers have 70 years experience between them and have seen the insulation seen in REHAU pipes and similar become brittle and turn powdery over time. That said if you get a leak in Uponor water gets in the oinion skins.

Pay ya money, take your choices. Same old story. I just hope I don't have to see the stuff again now it's buried!

 

[Bernt]

the uponor pre-insulated pipe is more like Rehau's cheaper version.

 

[farmerfred86]

Should anyone be interested we have about 7m of Calpex Duo (Brugg) pipe left over 2 different sizes... Might come in handy on some jobs!

 

[Dman2]

Finally dug a test hole on ours today and through the steam coming out of the hole, we determined that the insulation was breached and was now full of water.
New pipe going in on Monday, Ravithermex this time.
Could here the guy crying in the background when his contractor gave him the news

 

[frustratedfarmer]

Ouch!

Have you concreted back over already?

Need to lay 35m of pipe which is going to cost roughly £1100

What used 50mm Celotex(insulation board) cut a groove out for the 32mm pipe and put another 50mm board on top and put this in the trench isn’t this the same thing?

No.
Try Flexenergy - we used and works ok as per heat loss calcs. and reasonable priced.
