TOOL FOR DETECTING CORROSION CRACKING UNDERGOES U.S. TRIALS
Full-scale tests of an in-line inspection tool specifically designed to detect stress corrosion cracking (SCC) were completed last month with the tool's first ever run in an in-service U.S. gas pipeline. British Gas Inspection Services Inc., Houston, brought the 36-in. crack-detection tool (CDT) to the U.S. after trials in Canada earlier this year. Commercial availability is set for 1994.
