A method for cutting a wound hose (1), made from mutually engaging windings (11, 12, 13, 14) of a metallic tape (2), with the wound hose (1) being welded in a predetermined axial area (10) and then cut within the area (10) essentially in a plane (6) extending radially, with the wound hose (1) being axially compressed in the predetermined area prior to welding such that in the area (10) a mutual contacting of the windings (11, 12, 13, 14) occurs. The welding is performed along a predetermined number of windings (11-14) in the area (10), and the welding energy required for welding the windings is introduced via the area of the winding hose into it. Additionally, an accordingly produced wound hose (1) is provided and a device suitable for its production.

A tool for manipulating a tubular, such as casing or production tubing, in a downhole environment, this described. The tool comprises a housing defining a chamber, the chamber having at least one outlet, a propellant source located within the chamber and an ignition mechanism for igniting the propellant source. Upon ignition of the propellant source, the propellant deflagrates, creating at least one stream of combustion products, the chamber directing the stream of combustion products through the/each outlet, towards the tubular to be manipulated, the/each stream of combustion products combining with at least one modifying agent to manipulate the tubular.

An apparatus for locating a hardware at a desired location on a tubular structure of a machine includes a linear element including a plurality of linear reference indicia thereon, a slider coupled to the linear element, an angular element including a plurality of angular reference indicia thereon, a hardware locator coupled to the linear element and adapted to engage with the hardware to locate the hardware at the desired location on the tubular structure, and a reference hardware locator coupled to the angular element. The angular element is coupled to the tubular structure such that the reference hardware locator engages with a pre-existing hardware mounted on the tubular structure. The pre-existing hardware is used as a reference to locate the hardware at the desired location on the tubular structure.

An apparatus for torch cutting large pipe with a pair of split discs mounted to the pipe, one of the discs being a split ring gear. A circumferential track is formed in the facing surfaces of each of the discs. A driver mechanism is mounted on a set of rollers that operate in the tracks. The driver mechanism has a pinion to engage the split ring gear teeth so that turning the pinion causes the driver mechanism to move around the pipe. A torch is mounted to the driver mechanism in a position to cut the pipe as the driver mechanism moves around the pipe.

A pipe cutting assembly and method of use thereof for cutting level vertical pipes is provided. In one form, the pipe cutting assembly includes an adjustable arm including: at least one horizontal guide body movably mountable to and radially extending from a circular guide of the pipe cutting assembly; at least one vertical guide rail slidably mountable to the at least one horizontal guide body and horizontally moveable relative thereto; and a cutting torch mount for mounting a cutting torch, said mount slidably mountable to the at least one vertical guide rail and vertically moveable relative thereto.
