A system for making a connection between a first tubular member and a second tubular member having coincident bores for conveying a fluid, the connection having an axis in the general direction of flow of said fluid therethrough, the system comprising a connection (1) and a tensioning tool (100), the connection having a first tubular end (6) comprising a first end flange (16) having an end face (17) and a collar (20) comprising a sleeve (21) and an end stop (30) fixed to the sleeve (21), said sleeve (21) arranged about said flange (18) and said end stop (30) arranged about said tubular end (6), said collar (20) slideable along said tubular end (6), the connection further having a second tubular end (7) comprising a second end flange (43) having an end face (45) and a locking nut (50) about and slideable along said first tubular end (7), the tensioning tool (100) for applying axial tension to said collar (30) relative to said second tubular end (7) characterised in that at least one of said sleeve (20) and said second tubular end (7) has a set of parallel circumferential grooves (23,47) therein and said tensioning tool (100) has a set of ridges (142), the system comprising the steps of moving said set of ridges (142) into said set of grooves (23,47) and applying an axial tension to said collar (20) relative to said second tubular end (7).
A system for making a connection between a first tubular member and a second tubular member having coincident bores for conveying a fluid, the connection having an axis in the general direction of flow of said fluid therethrough, the system comprising a connection and a tensioning tool, the connection having a first tubular end comprising a first end flange having an end face and a collar comprising a sleeve and an end stop fixed to the sleeve, said sleeve arranged about said flange and said end stop arranged about said tubular end, said collar slideable along said tubular end, the connection further having a second tubular end comprising a second end flange having an end face and a locking nut about and slideable along said first tubular end, the tensioning tool for applying axial tension to said collar relative to said second tubular end characterised in that at least one of said sleeve and said second tubular end has a set of parallel circumferential grooves therein and said tensioning tool has a set of ridges, the system comprising the steps of moving said set of ridges into said set of grooves and applying an axial tension to said collar relative to said second tubular end.
A connection having a first tubular end comprising a first end flange having an end face a collar comprising a sleeve and an end stop, said sleeve arranged about said first end flange and said end stop arranged about said first tubular end, said collar slideable along said tubular end, the connection further having a second tubular end comprising a second end flange having an end face and a locking nut about and slideable along said second end characterised in that the end stop lies within the sleeve and is concentric therewith, the end stop threaded to the sleeve.
