Ideal Detonators Pvt. Ltd., manufacturers the Non Electric Initiating device SRIDET which combines the versatility and advantages of Electric detonators and fuse.
SRIDET basically consists of a plastic tube carrying a very small quantity of explosive material on its inner surface crimped with a Delay Detonator shell. The Delay Detonator shell consists of 70cgs of PETN making it No. 8 strength along with the initiating primary charges ASA and the required delay element.
When the Shock Tube initiated, a low order shock wave with a velocity of 1900meters/sec passes through the tube and initiates the Delay
Detonator. The traveling shock wave is totally confined to the inner walls of the shock tube and no damage happens to the tube. The shock
tube can be initiated either with a Detonator or with Detonating fuse.
Ideal Detonators Pvt Ltd produces three types of SRIDET
SRIDET ( PETN Nonel Tube)
SRIDET – C ( PETN Nonel Tube)
SRIDET – I (HMX Nonel Tube)
The unique features of the SRIDET are
1) The shock tube is a co extruded double walled tube with thin coating of explosive charge
2) The explosive charge is highly reliable
3) The tube is oil resistant and moisture resistant
4) Simple and safe to handle and the user is not exposed to direct handling of any explosive material
SRIDET is designed and developed for
a) Sequential firing.
b) To reduce ground vibrations.
c) To reduce charge per delay in sensitive areas.
d) To provide the true bottom initiation in the blasts.
e) To provide good fragmentation .
f) Less flyrock.
g) Less air blast.
h) Maximum safety towards stray currents, leakage currents and air born static charges.
There are 3 types of SRIDETS for various applications :
1. SRIDET TOPLINE
2. SRIDET DOWNLINE
3. SRIDET DOUBLE DET
