I cannot be as specific as I think you would like, but it sounds like 19th century technology at the earliest. It might conceivably (but improbably) by late 18th century. The first reference that I can think of for the production of cast iron pipes on a large scale is when John Wilkinson made pipes for the Paris Waterworks in the late 1770s or early 1780s.
I consider that the ability to produce gas-tight joints in cast iron pipes was a significant factor in the development of blowing blast furnaces through two or three arches (rather than one) and a factor in the increase in the size of furnaces, which began in the early 19th century, or possibly about 1790.

Hi,
I have today seen lengths of cast iron pipes, in situ. They are c75mm
dia and c 3 m from socket to spiggot with smaller joints at c 1m
(presumably made off site). Can anyone on the list suggest an earliest
date for this technology. The date of the adit which supplies the water
is unknown as is the location to which the water went.
