1 HydroFORM Phased Array Corrosion Mapping System Part 1 Equipment Overview

2 HydroFORM Corrosion Mapping System - Equipment The HydroFORM Phased Array System is designed to perform internal and external corrosion\erosion mapping on piping by use of a semi-automated encoder scanner without the use of high speed mechanical raster scanners or computer based software beyond the Omniscan MXU. The HydroFORM corrosion mapping system consists of the following components: Omniscan MXU 16:128 Phased Array Instrument. Omniscan MXU Software Version 2.0R21 or later Olympus HydroFORM scanner Scanner (Olympus P/N: Hydroform-K-Manual) Olympus 2-Axis CHAIN Scanner for Piping (Olympus P/N: Chainscan-XY38) HydroFORM Adaptation Kit for use with CHAIN Scanner (Olympus P/N: Hydroform-A-ADPchain) 7.5L64-I4-P-7.5-OM Phased Array Probe (Custom 1mm pitch X 64 elements, 7.5MHz ) Consumable Foam Seals for Water Column Water supply 2

3 HydroFORM Corrosion Mapping System Omniscan MXU The HydroFORM Phased Array System is designed to be used with the Omniscan MXU instrument and latest standard MXU software. No specialized software package is required. Corrosion mapping, weld inspection, or other applications can be performed using the standard software package. Although extremely beneficial for specialized inspections such as HIC detection\sizing, angle beam weld root corrosion, microbiological (MIC) attack, pitting, etc., the Multi-group option for the Omniscan MXU is not required for standard zero degree single group corrosion mapping. 160 megabyte and 300 megabyte file saving options (160 standard) Up to 6 hours acquisition time with two internal batteries **** Although the HydroFORM Corrosion Mapping system is not inherently incompatible with the Omniscan-M platform, due to the limited data storage, one axis encoder limitation, and reduced analysis capabilities it is not supported in the training and NPI documentation. 3

4 HydroFORM Corrosion Mapping System Omniscan MXU Software The HydroFORM Phased Array System is designed to be used with the Omniscan MXU instrument and latest standard MXU software. Corrosion mapping, weld inspection, or other applications can be performed using the standard software package. Omniscan MXU software version 2.0R20 or later can be downloaded from the support section of the ONDT webpage at Although extremely beneficial for specialized inspections such as HIC detection\sizing, angle beam weld root corrosion, microbiological (MIC) attack, pitting, etc., the Multi-group option for the Omniscan MXU is not required for standard zero degree single group corrosion mapping. 4

5 HydroFORM Corrosion Mapping System Omniscan MXU Software Changes to the Omniscan MXU software in version 2.0R20 and later related to the HydroFORM system include: C-scan compression to ensure no data points or relevant readings are missed when the number of data points in the data file exceed the display pixels available in the C-scan display. Corrosion specific Readings such as thickness and position for the entire C-scan and within the cursor zone. Color palette range and thickness range behavior. 5

6 HydroFORM Corrosion Mapping System HydroFORM HD MAPPER The HydroFORM can be attached to semi-automated, full mechanized scanners, or used independently for manual encoded one line scans. The scanner concept creates a local immersion technique by securing the PA probe and enables conforming to rough and uneven surfaces while maintaining a constant water column. Low water requirements and Integrated water ports Easy synchronization on front wall echo for OD and ID corrosion monitoring. Minimum tools required for use. Wedge reflection is minimized. Adjustable water column height. Magnetic and non-magnetic wheels. Self centering probe position. Integrated wheel encoder. Industrial design for harsh environments 6

7 HydroFORM Corrosion Mapping System HydroFORM Manual When used in the manual configuration without a scanner, the integrated encoder provides one line scans of approximately 60mm wide X 1mm resolution depending on aperture used. No additional scanner required for manual encoded one-line scans. Supplied with magnetic wheels for maximum stability. Quick radius adjustment allows inspection of pipe diameters without changing hardware or wedge. (Patent pending) Surfaces Convex: 4 in. OD to Flat Concave : 10 in. ID to Flat 7

8 HydroFORM Corrosion Mapping System HydroFORM Semi-Auto When used with the CHAIN Scanner, provides one line scans of approximately 60mm wide X 1mm resolution depending on aperture used. Can acquire up to five complete lines of data (60mm X 5 revolutions = C-scan of 300mm X pipe diameter) without resetting the CHAIN Scanner position. CHAIN Scanner can be quickly repositioned while maintaining precision position for additional coverage. Data files can be merged together for C-scans larger than 300 megabytes (Requires Tomoview). Can be configured with magnetic or non-magnetic wheels. Both included in HydroFORM-K-ADPchain package. Quick radius adjustment allows inspection of pipe diameters without changing hardware or wedge. (Patent pending) Surfaces Convex: 4 to 38 in. OD Flat 8

9 HydroFORM Corrosion Mapping System HydroFORM Adapt Kit The adaptation kit contains all the required hardware to adapt the HydroFORM to a standard Olympus CHAIN Scanner (Olympus P/N: Chainscan-XY38) Crank handle for faster indexing Encoder junction with Lemo connector for quick change between the Mini-Wheel and CHAIN Scanner signal Reversed spring loaded arm for HydroFORM scanner attachment Four plastic wheels Parts to allow the CHAIN Scanner to inspect Flat surfaces 9

10 HydroFORM Corrosion Mapping System 7.5L64 Phased Array Probe 1mm pitch X 64 element linear array. 7.5 MHz frequency for optimized near surface resolution. Custom housing design for HydroFORM scanner. 60mm wide acquisitions based on four elements aperture. Optimized acoustics for corrosion mapping applications. Up to 1 mm near surface resolution under optimum conditions. 10

11 HydroFORM Corrosion Mapping System Consumable Foam Seal Foam seal to maintain water column and conform to irregular surfaces. Consumable material to be replaced periodically. Will deteriorate differently based on pipe surface condition. Can be replaced in less than 5 minutes. Tough durable Teflon surface for extended life. The HydroFORM system initially comes with 100 replaceable seals. Additional seals available with short delivery time. 11

12 HydroFORM Corrosion Mapping System Water Supply System The HydroFORM HD MAPPER requires a constant water supply to maintain the water column in the chamber. Different pressure is required to initially fill the chamber and clear the bubbles, and to maintain a constant water column during scanning. Electric Water Pump (CFU03) Requires VAC power source. Supplies constant controllable water pressure for optimum scanning speeds and production. Removes the skill and time out of maintaining constant water column for easier use and faster production scanning. Manual Water Pump (WTR-Sprayer-8L) No power required 8 liters reservoir Manual water pump will reduce production and data quality depending on surface condition of component. Not recommended where a power source is available for electric water pump Not capable of maintaining constant consistent pressure for fast acquisition. 12
