The F and K pipecharges consist of a powder explosive containing nitroglycol and diatomite packaged in a polypropylene tube.
K-pipecharges are specifically designed for dimensional mining in quarries and other applications that require smaller and controlled charges.
For F-pipecharges, the primary application is smooth blasting and pre-splitting above ground and in tunneling work, but they can also be used in other types of blasting where a precise amount of explosives is required. When contour lines are blasted using F-pipecharges, damage to remaining rock is minimized, resulting in durable, high-quality walls. In addition, the remaining walls will be given the desired contour lines.
The pipes (Ø 17mm) can be equipped with locking sleeves that center the pipes in the borehole and prevent them from being thrown out of the hole. When the pipe is centered, an air cushion is formed between the pipe and the wall of the hole, which reduces the risk of unnecessary cracking in the rock.
