The K-pipecharges consist of a powder explosive containing, i.a. glycol dinitrate and diatomite. The K-pipecharges are used in dimensional stone quarrying and for tasks that usually require very light charging.

The explosive is packed into plastic pipes. The pipes are equipped with expansion sleeves, which enable the pipes to be fixed in the middle of the borehole and prevent them from being thrown out of the hole. When the pipe is fixed, an air cushion is formed between the pipe and the wall of the hole, that on its own part prevents the rock from unnecessary breaking.

The pipecharges are available also without the expansion sleeve.

The pipecharges are highly frost-resistant, but they are not fully water-resistant.

The use of K-pipecharges requires a detonating cord in order to assure continuous detonation. The pipecharges are typically ignited by using a detonating cord, allowing several boreholes to be detonated simultaneously. This method produces a better rock surface compared to applications without a detonating cord.
