| Title | Part 21 Report - Potential Minimum Wall Thickness Issue on Certain Posi-Seal Valves |
| Event Description | The following report was received via email:
Pursuant to 10 CFR 21.21 (a)(2), Fisher Controls International LLC ('Fisher') is providing required written interim notification of a potential failure to comply concerning minimum wall requirements in the packing box region of certain Posi-Seal valves [A11]. On March 10, 2017, Fisher discovered a minimum wall issue while processing an order. While the order at issue was corrected prior to shipment, Fisher is currently engaged in an extent of condition investigation to determine whether the noncompliance extends beyond the specific order. Fisher anticipates completing this investigation and disseminating additional information on or before June 9, 2017. Appropriate corrective action will be initiated to prevent reoccurrence. Should there be any further questions concerning this matter, please contact Benjamin Ahrens, Manager, Quality by email at Benjamin.Ahrens@Emerson.com or via phone at 641-754-2249.
The following report was received via email: Fisher Information Notice: FIN 2017-03 9 June 2017 Subject: Potential Minimum Wall Thickness Issue on Certain Posi-Seal A11 Packing Boxes Purpose: The purpose of this Fisher Information Notice (FIN) is to alert affected customers that, as of 10 March 2017, Fisher Controls International LLC (Fisher) became aware of a situation which may affect the minimum wall thickness of certain Posi-Seal designed valve bodies. Fisher is informing affected customers of this circumstance in accordance with Section 21.21 (b) of 10 CFR 21. Discussion: Fisher engineering identified a potential minimum wall thickness issue on a 14 [inch] Posi-Seal Type A11 body drawing in the process of fulfilling an order. The valve body drawing was such that it was possible to machine the packing box region of the valve body neck within drawing-specified tolerances but fail to meet minimum wall thickness as required by ASME B16.34. As a result of this discovery, the affected order was halted and an investigation was initiated. Extent of Condition: POSI-SEAL manufactured and supplied Type A11 valve bodies from their location in N. Stonington, CT to the nuclear industry prior to being acquired by Fisher in 1985. An extent of condition investigation was conducted to identify all potentially affected body drawing numbers and instances of orders shipped by Posi-Seal and subsequently by Fisher that could have had minimum wall issues. The scope of this investigation included all sizes and appropriate pressure classes of potentially affected valves shipped from either Posi-Seal or Fisher. The investigation concluded that only the 14 [inch] size for certain body drawing numbers are affected. Other sizes or types of valves are not affected by this FIN. Equipment Affected by this Fisher Information Notice: Items subject to this FIN are confined to the 14 [inch] Type A11 valve bodies having original Posi-Seal drawing/serial numbers referred to in the attached Appendix A. All affected equipment was shipped from N. Stonington. No affected equipment was shipped from the Fisher Marshalltown, IA location. Action Required: Fisher has revised the affected drawings to ensure the minimum wall requirements of ASME B16.34 are met. Fisher will also work directly with the affected customers to evaluate and resolve the potential minimum wall thickness issues. The in-process order was stopped and will be verified to meet minimum wall thickness requirements prior to shipment. 10 CFR 21 Implications: Fisher requests that the recipient of this FIN review it and take appropriate action in accordance with 10 CFR 21.
