YELLOW ALKATHENE GAS PIPE

[Arnold9801]

Advice please... I have a Calor tank where the feed pipe splits with a T joint. I need one of the two off- feed pipes terminated and was hoping there is a butt fitting that can be used to do this. Ive had had two engineers around this week to give me a quote and they were both uncertain and felt the only option was to heat weld a fitting on the one of the two pipes that needs terminating.

 

They did mention the exact name of the heat device to do this, though I forget what it’s called. One did say there maybe an easier way of sealing the end without this electrical heating device. 

 

Could anyone advise me if me if there is a cheaper alternative to terminating the pipe and sealing it using the heat weld device as hiring

it would be quite expensive.

Can they not take the t out and install a straight joint. 

Or I suppose that’s a welded connection as well.

Yes that would mean a welded connection.

Can you not use one of these.    https://gasproducts.co.uk/plumbing/mdpe-gas-pipe-and-fittings/philmac-mdpe-comp-gas-fittings/philmac-mdpe-25mm-x-25mm-gas-compression-coupler.html

Is it going to be buried or visible ..?? You can cap MDPE with copper compression fittings but it’s not advisable underground.

It’s a “fusion weld” fitting that you want ( need ). 
If it was me, I’d not fit anything else, especially on higher pressure ( if LPG ? ). The last thing you want is a tank of gas gone to an undetected leak.
No short cuts with gas in my world sorry.

Not sure what size pipe you use, but as a very quick search:

You need to check which family of gas this is permissible to be installed onto. 
The advice needs to come from the actual installer, not an Internet forum ?.

As @Nickfromwales said - certain installations require different rules.

 

Also depends on where the join needs to be - pre or post regulators, above or below ground etc as the rules for LPG are different. You need a GSR engineer with a ticket for LPG to work on this.

It’s 25mm yellow.
