摘要

Navy jets launching from carriers routinely subject flight deck personnel to 150 decibels or more. Because a mere 85 decibels can damage hearing, the Navy, understandably, is keen to reduce jet exhaust noise. At the California Institute of Technology in Pasadena, Tim Colonius, professor of mechanical engineering, and his team have been using mathematical models to understand how jet engines generate noise.

1. THE STANDARD PIPE MARKETA6Our projection of full year 2017standard pipe shipments suggests anincrease over ’16 of about 34.7% Part of thatgrowth, as we’ve been discussing, is relatedto a more appropriate relationship betweenBlack PE standard pipe and line pipeproducts. Keep in mind that the walltolerance on standard pipe is twice what it ison API line pipe yet often these products aremade to the higher tolerance and dual ortriple stenciled. [J] .

3. Interpipe boosts 2018 non-CIS pipe and wheel salesThis year, Ukrainian pipe-maker Interpipe is set to pursue increased sales of high-margin,technically sophisticated products -- pipes with premium threads, wheelsets, machinedwheels and finished axles.The company will continue to face and mitigate the same risks: trade barriers, low rates ofscrap collection in Ukraine and a shortage of qualified production personnel, Interpipe CEOFadi Hraibi said in a results report distributed Tuesday.
