ABSTRACT:
A clamp for forming a seal on a pipeline section, the clamp comprising a pair of complementary clamp members to be clamped together, each clamp member having an inner surface with a pair of axially spaced, circumferentially extending circumferential seals, and one clamp member having a pair of circumferentially spaced longitudinal seals which extend axially to bridge the gaps between the opposed circumferential ends of the pair of circumferential seals to define four junction zones where the circumferential seals and the longitudinal seals abut, and retention means at each junction zone to connect the circumferential and longitudinal seals together in the retention zones, and at the same time connect the seals to the clamp member at the junction zones. The clamp includes corner seals to provide back-up sealing for the junction zones. The clamp includes heat protection grooves to protect certain of the clamp seals. The clamp may include a pipe branch to provide a hot tapping facility. Embodiments of the clamp have an optimized body design to provide for weight minimization.
