The percussion initiator is designed to initiate detonation in an explosive chain of expendable jet guns conveyed on tubing. BVT PI is installed in the firing heads of UFH, MFH, HFH, AFH.
The device is initiated by a shock pulse from the firing head impactor and transfers the detonation to the detonation transmission device (DTD, Booster, etc.).
BVT PI is used in leak-proof conditions, without contact with the well fluid. The device does not contain initiating explosives and is characterized by enhanced operational safety.
