Hydrogen Embrittlement Failure Of Nickel Alloy UNS N07716-140 Tubing Retrievable Safety Valve Component Installed In A Sour Production Gas Well

Product Number: 51322-17709-SG

A 9-5/8 inch (244.8 mm) Tubing Retrievable Safety Valve (TRSV), which is a type of Sub Surface Safety Valve (SSSV) governed by API Specification 14A, was found to have failed when retrieved during workover operations in a gas production well in June 2019. This TRSV was installed in the well in November 2013 and was in production service from 2015 until November 2018 when the well was shut in for maintenance of surface equipment. In March 2019, with the well still shut in for maintenance, a rapid increase in the tubing-casing annulus (TCA) pressure was observed.

Improving Hydrogen Embrittlement Resistance Of Precipitation Hardened Nickel-Alloys

Product Number: 51321-16673-SG

Author: Luca Foroni, Carlo Malara

Publication Date: 2021

Precipitation hardened (PH) Ni-alloys are widely used in the oil and gas industry since they provide an excellent combination of corrosion resistance and mechanical strength. Their use in the manufacture of API1 6A pressure-containing and pressure-controlling components is subject to the stringent requirements of specification API Standard 6ACRA. However, matching the requirements of API Standard 6ACRA does not preclude susceptibility of some PH Ni-alloys to hydrogen embrittlement (HE) and this in some cases has led to premature and unexpected failures of components made from such
materials.(
