Project Detail
Project: North Mountain Energy Project
Equipment: Air Inlet Filter Equipments
Date: May 2012 to to April 2013
Vendor Location: Fabricator of Air Inlet Filter Equipments in Cohahuila, Mexico.
Visual Inspection on Hot Dip Galvanized Surfaces per ITP-104043-01 Rev 1 Item 13, Customer Spec 295-395435 Item 020 and ASTM A123/ASTM E376 Standards.
Item Inspected: Hot Dip Galvanized Structure Columns.
Findings: Observed a lot of areas on Galvanized Surfaces of Columns repaired by brush retouch since as explained from Vendor, the heat input from the Hot Dip Galvanizing produced a critical deviation on straightness of columns, which they tried to fix by heat application at an important number of locations, damaging locally the galvanizing, which was repaired subsequently by brush retouch. Fraza Team has reviewed this issue with Vendor Representatives and it has been confirmed and agreed, the quantity of locations repaired by brush retouch is Not Acceptable to ASTM Standards referenced above.
Re-Inspection: Per Customer Direction, all Referenced Columns have been Hot-Dip-Galvanized again in accordance with Standard ASTM A-123, as well all of them dimensionally inspected for straightness by Vendor QC Team and found acceptable to Project Requirements. See Photo as Illustration on referenced Issue.
Benefits to Our Customer: By using Fraza Inspection Team, Customer saved a lot of of time and money preventing excessive expenses per back charges for Re-works at field site per unacceptable issues on Galvanizing if Not Corrected/Repaired in timely manner at Vendor Shop.
