Wall thickness measurements of corrosion under pipe supports

Page last modified

April 11 2024

The QSR1® semi‑automatically scans predefined sections of straight pipelines for corrosion under pipe supports (CUPS).

The QSR1® can provide a quantitative measure of the average wall, as well as the remaining wall thickness down to half of the nominal wall thickness.

This instrument is suitable for motorised guided wave scanning on predefined sections of straight pipelines, with the added compatibility to operate with GUL’s cloud‑based platform.

Currently not ATEX certified (under development)

Specification

Specification Title	Specification Description
Areas of Application	Currently QSR1® procedures are designed for scanning of simple supports.
Capabilities	Easily set-up for diameters between 6” and 24”. Automated configuration ensures performance independent of pipeline thickness variations.
Implementation time	Quick and easy setup. Obtain remaining wall thickness profile within minutes thanks to the fast data processing by WaveProQSR™.
In-service inspection possible	Measure remaining wall thickness at locations affected by CUPS while keeping the pipeline in service. Minimize risks by avoiding unnecessary lifting your pipeline, and still be able to make informed integrity decisions.
Inspection	Indirectly scan a pipe section to evaluate the severity of CUPS – Corrosion Under Pipe Supports.
Maintenance	The QSR® system has been designed to operate under real field conditions. The equipment is rugged and requires minimum maintenance. Worldwide field tests have proven the equipment can cope with real site conditions.
Measurement	QSR1® is an indirect quantitative scanning tool; the only system in the market that can provide a measurement to input in your asset integrity software.
Range	Pipe diameters between 6” and 24”. Nominal thickness between 6mm and 13mm (¼” to ½”).
Support	GUL provides full training and technical support on all its products. QSR® can be purchased with an option of data auditing through Trunk®, GUL’s cloud based system.
Temperature	-20°C to +70°C (0 to 160°F).
