Abstract
A tool for severing or assisting in the severing of a conduit includes a housing defining a void arranged, in use, to at least partially encircle a conduit and an at least one void access, the void access having a void access inlet in fluid communication with the housing and a void access outlet being in fluid communication with the housing void. At least one propellant source is located within the housing. An ignition mechanism is provided for igniting the propellant source and at least one modifying material. Upon ignition, the propellant source deflagrates, creating at least one stream of combustion products, the stream of combustion products flowing out of the tool through the void access into the void, the void access channelling the stream of combustion products towards the conduit, the stream of combustion products combining with the modifying material to sever or assist in severing the conduit.
