Project Detail
Project: 529618-High Coast-3
Equipments: Module Piping Spools
Date: November 2019 to April 2020
Vendor Location: Fabricator of Piping Spools in Tamaulipas, Mexico.
Witness on Measurement of Anchorage Profile per ITP 529618-HC-01 Rev 1, Item No. 5.2 and Approved Vendor Paint Procedure HC-PC-02 Rev 2, Paint System Nr 1.
Inspected Item: Lot of Spools identified as Control Number H0043-02, H0053-01 and H0073-01.
Findings: Specified Range for Anchorage Profile, 2.0-2.5 mils, Actual as Measured, 2.8, 2.9 and 2.8 Mils. Exceeded above the max specified. Vendor Team was warned on the risk of leaving peaks unpainted due to exceeded anchorage profile, producing rusting, therefore They were aware to adjust their blasting parameters such as the distance between the blast nozzle to the item being blasted, air pressure etc in order to bring the blasting profile to within specification.
Re-Inspection: Based on the values measured during last witnesses on surface preparation as well as the anchor profile records per documentation review on spools inspected in the last visits by Fraza Team, Vendor has kept the anchoring profile under control and within the specified ranges. See photos as Illustration on referenced issue as originally found.
