Product Description
DST Slim Hole Downhole APR Drill Stem Testing Tools
Techcore Oil Tools manufactures full-bore, annular pressure operated downhole testing tools compatible with 4 1/2" to 20" casing sizes. These DST tools feature outer diameters of 3 7/8" and 5", with working pressures up to 105 MPa and temperatures up to 425°F.
Material Specifications & Compliance
Constructed in compliance with NACE MR0175 standards using AISI 41XX alloy steel with average hardness of 30 HRC. Critical components such as nitrogen cases utilize high-hardness materials, while ball valves feature Inconel 718 construction. For extreme conditions including high H2S, CO2, acid, and HCL environments, we recommend Inconel or other high-nickel alloy steels.
