Process Management Fisher Information Notice: FIN 2016-05 20 June 2016
Subject:
Insufficient Valve Cage Hardfacing Equipment Affected by this Fisher Information Notice:
Fisher Controls International LLC 301 South First Ave P.O. Box 190 Marshalltown, Iowa 50158-0190 USA T (641) 754-3011 F (641) 754-2830 Items subject to this Fisher Information Notice (FIN) are confined to the equipment and orders referred to in Table 1 attached below ("Equipment"). Specifically, "Equipment" refers to the 8" sized hardfaced HPNS cages supplied per the order numbers listed in Table 1.
Purpose:
The purpose of this FIN is to alert affected customers that, as of 29 April 2016, Fisher Controls International LLC (Fisher) became aware of a situation which !)lay affect the performance of the aforementioned Equipment, including its safety-related function.
Fisher is informing affected customers of this circumstance in accordance with Section 21.21 (b) of10CFR21.
Applicability:
This FIN applies only to the Equipment identified in Table 1, which lists serial and order numbers of the Equipment that was delivered to affected customers.
Discussion:
The Equipment in question is subject to CoCr-A hardface overlay requirements. The CoCr-A overlay deposit thickness must be 0.060" minimum after machining. However, the cages supplied in fulfilment of the orders listed in Table 1 may have insufficient hardfacing depth on the inside bore diameter at the top of the cages (approximately 1.50" from top).
This issue first came to Fisher's attention when a material grade inspection revealed insufficient cobalt. Subsequent PMI testing confirmed the upper section at the top of the cage fell short of expected CoCr-A. Two in-stock cages were sent to a third party accredited laboratory for macroetch examination and hardness survey. The results of this survey confirmed the top of the cages did not meet the minimum hardness requirement of 34 HRC and further confirmed the insufficiency is limited to the uppermost 1.50" of the inside bore diameter of the cages.

Process Management Fisher Controls International LLC 301 South First Ave P.O. Box 190 Marshalltown, Iowa 50158-0190 USA T (641) 754-3011 F (641) 754-2830 The absence of hardfacing at the mating surface between cage and plug creates the potential for galling, which could prevent the valve from performing its intended safety function. Testing has been conducted to analyze the risk of galling. Typically, galling is observed in cycle tests well exceeding the 600 cycle recommended lifetime for the Equipment. However, testing has proven galling to be an unpredictable phenomenon and could occur prior to the recommended lifetime of the Equipment. There are no known field issues with the affected Equipment.
Extent of Condition:
The problem of post-hardfacing material shrinkage is associated with the ratio of bore diameter to cage wall thickness. Large bore diameter thin-walled cages are at greater risk for material shrinkage. A third party accredited laboratory performed additional macroetch supplemental tests and evaluations on similar cages of varying bore sizes. It was determined that this issue is unique to the 8" sized HPNS cages.
Action Required:
Fisher will provide the affected customers with a properly coated cages at Fisher's cost. In addition, a Corrective Action Request (CAR 1804) has been initiated by Fisher to prevent reoccurrence of this issue.
