The DST tools manufactured by ZZ Top is full bore type and annular pressure operated, 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 butalso 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 which import from USA directly.

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.

For other redress parts like O rings, rupture discs are also optional from US parker and Fike USA, and as per our test 

Chinese are also in good performance, those parts can be available once request.
