GRADE 550 LINE PIPE PASSES TESTS FOR CANADIAN PROJECT

Tests by NOVA Corporation of Alberta, Calgary, on Grade 550 pipe have led to the world's first specified use of the high-strength material in a large-diameter, high-pressure natural-gas pipeline. Use of the pipe allows significant material cost savings by permitting thinner wall requirements. This savings is potentially enhanced by the fact that this higher strength pipe requires no significant changes to conventional methods of pipeline construction. The NOVA project also employed a mechanized, pulsed, gas metal arc welding system for the first time on this grade of pipe. This article provides details on the pipe's structural limits (diameter and thickness), test program, manufacture, tensile strength and toughness, and construction methods.
