A fixture for fixing a pipe end portion to an apparatus, comprising: - a shaft being axially displaceable along an axis in a D1 direction and an opposite D2 di- rection, - a plurality of segments displaceable between a release-position and a fixing-position, each segment comprises a wedge shaped inner face; - a cone comprising a tapered wedge face abutting the wedge shaped inner face; and - a release spring element biasing the segments in the axial direction towards the release- position, such that an axial displacement of the cone in the D1 direction displaces the segments radially outwards, and an axial displacement of the cone in the D2 direction displaces the segments radially inwards The cone comprises a cone centre hole and the cone is slideably engaged with the shaft. The fixture comprises a position spring element abutting the cone and bias the cone axially in the D1 direction.
A rigid fluid reservoir (630) for a hydraulic fluid (69), the rigid fluid reservoir (630) comprises a rigid house (6302) and an outlet (6306). The rigid fluid reservoir (630) is sealed from a surrounding environment (6305). The rigid fluid reservoir (630) comprises an inflatable device (6301), wherein the inflatable device (6301) is positioned within the rigid house (6302). The inflatable device (6302) communicates with the surrounding environment (6305) via a through hole (6303) in the rigid house (6302).
An apparatus (1) arranged for rolling a circumferential external groove (994) in a pipe (99) The apparatus (1) comprises a fixture (50) and a grooving tool (10). In a fixing- position the fixture (50) is configured to engage an internal wall (996) of the pipe (99) and fix the apparatus (1) to a pipe end portion (990) such that a pipe centre axis (X99) is coaxial with an apparatus centre axis (X1), and the grooving tool (10) is rotatable around the centre axis (X1). The grooving tool (10) comprises a hydraulic piston (12) and at least one wheel-holder (110), the hydraulic piston (12) is displaceable along the centre axis (X1), the hydraulic piston (12) is configured to displace the wheel-holder (110) in a radial direction relative to the centre axis (X1) between an idle position (1102) and a grooving position (1104), and the wheel-holder (110) comprises a grooving wheel (111).
A tool is for inside chip-separating processing of a tube. The tool has a housing which is rotatable around a center axis of the tool, a blade holder which is rotatable around an axis of rotation, there being a plurality of blades positioned along the periphery of the blade holder, and a guide element which is arranged to guide the blade holder between an active position and a passive position. Each of the blades has a surrounding cutting edge which forms a working plane which is arranged perpendicularly to the centre axis of the tool. The blades are arranged for alternating contact with the tube when the blade holder is rotating and is in the active position.
A tool (1) for inside chip-separating processing of a tube (90), the tool (1) comprising a housing (10) which is rotatable around a centre axis (XI) of the tool (1), a blade holder (21a, 21b, 21c) which is rotatable around an axis of rotation (X2), there being a plurality of blades (22a, 22b, 22c) positioned along the periphery of the blade holder (21a, 21b, 21c), and a guide element (30) which is arranged to guide the blade holder (21) between an active position (A) and a passive position (B). Each of the blades (22) has a surrounding cutting edge which forms a working plane (P22) which is arranged perpendicularly to the centre axis (X3) of the tool (1). The blades (22) are arranged for alternating contact with the tube (90) when the blade holder (21) is rotating and is in the active position (A).
