ABSTRACT:
There is disclosed a clamp useful for connecting a tie-in line transversely to a carrier pipe, comprising: a lower body portion and a upper body portion that when connected together define a tubular bore, the lower and upper body portions being adapted to clamp onto the carrier pipe; a set of gripping collets positioned with the tubular sleeve bore proximate opposed ends of the upper and the lower body portions to engage such a carrier pipe; a branch tap positioned between the gripping collets and extending from one of the body portions transversely to the tubular bore; a first seal and a second seal for providing a seal between the carrier pipe and the upper and the lower body portions, the first and second seal positioned within the transverse bore and between the gripping collets and the branch tap; and a set of axial seals to form axially extending seals between the upper and lower body portions during use and to connect the first and second seals during use. The connector is particularly useful to attach branch pipes to oil or gas carrier pipes submersed undersea.
