APR Drill Stem Testing Tools For Slim Hole Downhole Testing
The Drill Stem Testing Tools / DST tools manufactured by
Techcore Oil Tools is full bore type and annular pressure
operated downhole testing tools as per Halliburton tools, the DST
tools are applicable for 4 1/2” to 20” casing, the tools OD is 3
7/8” and 5”, Working pressure upto 105Mpa, working temperature upto
425F.
As per NACE MR0175 standard, the materials ZZ Top used is AISI41XX
Alloy steel with hardness in 30HRC in average but also consider the
high working pressure to choose high hardness material used in
Critical parts i.e. Nitrogen Case, for ball valve, the material is
Inconel 718
And for strict working condition such as high H2S, CO2, Acid and
HCL, we also suggest the material Inconnel or other high Nickel
alloy steel.
