Title: Effects of Hardness on Pintle Rod Performance in the Universal and Retained Gas Samplers

Technical Report ·
DOI:https://doi.org/10.2172/798673· OSTI ID:798673

Interaction between hardness of the pintle rods and the retainer rings used in the core samplers is investigated. It is found that ordinary Rockwell C measurements are not sufficient and superficial hardness instruments are recommended to verify hardness since in-production hardness of pintle rods is found to vary widely and probably leads to some premature release of pistons in samplers.
