A tale of two pipes. Both hydros going well on Snowdon

About the size of a small car and all remote control. impressive peice of technology which is tasked to spew out a kilometer of 550mm pipe

Today was another of those “I’m glad i do what i do” out in Hafod y Llan for an interpretation / engagement meeting to discuss how we share what we are doing at the farm. But that’s another blog. I had the chance to trape up and across Snowdon with John the project manager to see how the next milestone is going. Pipe fitting. Having flown the pipes up the mountain for the large hydro it’s now full steam ahead welding the 12m half a tonne and almost a tonne pipes together. This had involved tracking a not unsubstantial plastic welding machine up Snowdon to join all the large pipes together. This work takes two large 13t tonne diggers. One to feed fresh pipe and the other to pull and place the single long pipe. Both of which are either side of the very clever butt welding machine. Quality control is everything. They even test each and every joint by sending away the resulting removed plastic bead  to be tested to ensure the strength of the join. They have over a kilometer of this to do. Weather was perfect today (for me and the pipe)

At the other end of the spectrum is the 180mm pipe for the Gorsen hydro again on the farm which was welded down on the valley floor and then pulled up the mountain with the aid of a very nifty mobile capstan winch. Quite a steep site but the pipe is now in place and its full steam ahead with the turbine building which should be weather tight by this evening. It’s good to see such rapid progress
