Hawk Rope Access, Inc.
Inspect large areas of piping and vessels quickly, safely and accurately.
Industrial Rope Access is well suited for deploying Automated Ultrasonic Testing (AUT). Our TD-Scan Automated Inspection System is compact and can be easily situated by our technicians to scan difficult and awkward locations. Crawlers are deployed quickly and efficiently making maximum use of each calendar day while reducing overall costs and interruptions to normal operations.

The TD-Scan Automated Inspection System is a development of Technology Design. The resulting pulse echo, corrosion mapping, and weld inspection technology is deployed by Hawk Rope Access, Inc. using traditional or Industrial Rope Access techniques. Large areas of piping and vessels, such as those found in the refining and petrochemical industries, may be quickly inspected while reducing the cost of scaffolding for difficult to reach areas.

An Automated Ultrasonic inspection system uses conventional and special transducers to generate sound in the test material. These transducers are mounted to robotic crawlers, which articulate to cover large areas of vessel surface.
Any defects found with AUT weld inspection are manually checked by the certified technician to confirm reliability.
Weld Inspection
Pulse-Echo weld inspection uses single or multiple search units, set at specific angles, to inject sound into the test weld to search for discontinuities and defects. These angled
and zero degree search units can be mounted onto a robotic crawler which enables the inspector to cover large areas of weld in a reliable and repeatable manner, and in a shorter amount of time than doing the work manually.
The crawler rasters the transducers in a perpendicular motion to the weld in order to get full volumetric coverage of the material with the search units.
This is performed simultaneously from both sides of the weld. This technique detects, locates, sizes, and identifies the nature of the flaw.
Corrosion Mapping
Corrosion mapping is one of the more common AUT inspections performed today. It provides
reliable information to engineers and inspectors about the remaining wall and ID geometries of equipment and piping. The information is used to establish corrosion rates, equipment longevity, and maintenance and repair cycles. AUT corrosion scanning provides digital images which can be archived for future examination, and then regenerated and remapped to establish flaw extension over time.
The collected data is then displayed in color in multiple A-Scan, B-Scan, C-Scan, and D-scan images.
These images are helpful in distinguishing mid-wall inclusions such as laminations and blistering, from back-wall discontinuities like erosion and corrosion.
Indication of depth is color coded to provide the image with qualities which resemble a topographical map viewed from the inspecting surface.

All data is digitally recorded allowing repeatable scans for monitoring purposes.

Hawk Rope Access, Inc. is continually adapting and applying rope access techniques to new settings, we have gained acceptance for our methods by introducing safe, successful programs, specific to the needs of industry, while generating significant cost savings.

Hawk has a broad depth of experience and procedures for offshore oil platforms, refineries, power generation, hydroelectric plants, bridges, pulp and paper plants, amusement parks, shipping and more.
