The system in final inspection produces an automated dimensional inspection report for the OD and OOR of the pipe ends and body to assure compliance with API and other standards. When installed prior to cutting, the measurements can be used to fine-tune the tooling during a set up change, and then alarm whenever OD or OOR values approach the allowable limits so that an operator can intervene before a quality fault occurs.
Sensors are mounted on a precision space-frame and aligned via patented software techniques. Data sets from each sensor are internally transformed into a global coordinate system to render the complete cross-sectional profile image. Software measurement tools can be configured to display and record up to 180 OD values, one per degree, as well as maximum and minimum OD and OOR for the pipe ends and body.
FEATURES • Reliable due to its simple design
• Automatically measures pipe OD and OOR from 6" up to 24" (150 to 600mm) at two locations: in-line before cutting, and in final inspection
• Utilizes CrossCheck™ Line-Laser Sensors to
achieve the range and accuracy required for pipe mills
• A single measurement cycle instantaneously acquires about 5,000 data points (for a 24" pipe) in a precise cross-sectional plane in 1 millisecond
