HIGH PRESSURE SMDC
The High Pressure Shielded Mild Detonating Cord (HP-SMDC) assemblies are explosive transfer lines, consisting of a metal sheathed explosive core contained in a stainless steel tube. These assemblies, specifically designed for use in the oil and gas industry, are rated to withstand an external high well bore pressure of 30,000 PSI. The Mild Detonating Cord (MDC) explosive used in the SMDC assemblies is a high-temperature explosive which allows the MDC to withstand temperatures up to 500°F for 50 hours without degrading the effect of the detonation characteristics.
High Pressure SMDC [HP-SMDC] is are used to as an initiation/energy transfer between explosive devices in high temperature and high-pressure extreme environments. The HP-SMDC is a sealed device so it can provide energy transfer while submerged in the extreme environments.
HP-SMDC is currently used in high-temperature, high-pressure environments where point to point initiation is required and fragmentation / post function containment is required to protect perforating guns and pipe severance sub-assemblies.
