Hi Geoff
thanks for that. Sounds a bit easier than what I planned (diamond core
drill, back clean, stub weld, plastic foam former, pourable epoxy grout,
remove foam with petrol).
Cheers
Steve

Hi Steve,
Good to see Monty Python's humour is alive and well in the Shaky Isles.
Cement lined pipe branches are easily effected using a ss coupling from
Onesteel(Glynwed), Tyco (Wang) or Klinger. These are a clamp on unit with a
welded take off for the flanged DN 100 Branch. This way you dont have to get
into the pipe. The hole can be cut and surface repaired with a two pack
epoxy.
The coupling is then fitted to the DN 400 pipe. The coupling is fitted with
rubber seals to provide the seal. There are two types. 1) fitted with
serrated
teeth so you dont need a thrust block and 2) plain type where a thrust block
is
needed.
