SHOCK TUBE INTEGRATED SYSTEMS

Raikka Oy Shock Tube Integrated Systems (STIS) with starters and detonators are non-electric devices designed to initiate explosives of different types.

The STIS devices are insensitive to electrical and electromagnetic influences and they need no blasting machines for operation

According to customers requirements the STIS devices include 2mm or 3mm shock tube needed length, starter RAIKKA VS2010 or RAIKKA PS2012 and detonator.

The products are packed hermetically in aluminuim foil bags and UN-approved corrugated cardboard boxes classified as detonator assemblies, non-electric UN 0500, 1.4S

Shock Tube

The shock tube is a small diameter plastic tube coated on the innermost wall with a reactive explosive compound which, when ignited, propagates a low energy signal similar to a dust explosion. The reaction travels at about 2100 m/s along the length of the tubing with minimal disturbance outside the tube.

Detonator

The detonator, which is made of aluminium, is crimped on the end of the shock tube in a rubber seal. It contains a base charge of about 1g PETN for initiation of a charge. The base charge is instantly initiated by the explosive mixture of the shock tube without any delay.
