The relevant regulations in the field of automated flame-cutting technology stipulate various safety devices for the process-gas supply of a cutting torch. The invention relates to the simplified installation and maintenance of the safety devices and to a compact structure thereof. Proposed is a multi-functional safety module, in the module body of which there are integrated a first and a second safety element to prevent flame- or gas-blowout, and in which there is provided a mechanical plug-type connection for establishing a gas-tight connection between the safety elements and the corresponding gas lines of the cutting torch.

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.

A water torch with tip for providing separate streams of hydrogen and oxygen at its exit includes the tip. The tip has a tip inlet end and a tip outlet end. The tip includes an inner housing and an outer housing. The inner housing has an inner housing inlet port at the tip inlet end in communication with an inner housing outlet opening at the tip outlet end via an inner tip passage. The outer housing surrounds the inner housing. The outer housing includes an outer housing inlet port at the tip inlet end in communication with an outer housing outlet opening at the tip outlet end via an outer tip passage created between the inner housing and the outer housing. The outer housing outlet opening and the inner housing outlet opening are at approximately the tip outlet end, where the outer housing outlet opening surrounding the inner housing outlet opening.

A method and an apparatus efficiently and reliably cut a steel frame. The cutting method includes locating a cutting torch apart from the steel frame held by a holding device in a direction along a cutting surface, moving the cutting torch from a cutting start position to a first cutting end position in a first feed direction perpendicular to a supply direction along the cutting surface, while applying a flame from a fire port of the cutting torch in the supply direction and supplying cutting oxygen to thereby cut a part of the cutting surface, stopping the cutting torch at the first cutting end position and thereafter cutting an uncut part by moving the cutting torch from the first cutting end position in a second feed direction opposite to the first feed direction.

A subsea wet-mateable connector handle has a handle part, a bushing support ring, a resilient bushing, a connector mount and a securing pin. A method of manufacturing a subsea wet-mateable connector handle includes cutting a handle part from a sheet of inherently corrosion resistant metal plate by a two-dimensional cutting process. A bushing support ring and a bushing are assembled onto a limb extending from the handle part. A connector mount is mounted to the bushing and the connector mount and bushing are fixed to the handle part with the securing pin.
