.• <br />1.0 Genera] DeacriptTbn: <br />• <br />The scope of this project will be installation of two (2) parallel (in <br />the •ame trench) pipelines for non-flammable gaseous nitrogen service at 465 <br />psig initial operating pressure, n on-flammeble gaseous oxygen service at 350 <br />psig initial operating pressure. All lines will be hydrostatically tested and <br />rattd for 720 psig maximum •llawable operating pressure, each briefly <br />described bclov. <br />1.1 One (1) 16" O.D. oxygen pipeline and one (1) 16" O.D. nitrogen <br />pipelinc, each approximately 157,700 linear feet will originate at a <br />tie-in point approximately 6500 feet rest of U.C.C. Linde LaPorte plant <br />property and approximately 800 feet north of Hwy. 225 in the Exxon <br />saytovn-Bayport pipeline corridor, south within Exxon and Friendswood <br />corridors to Red Bluff Point area, across Galveston Bay, and then south <br />to terminate at U.C.C.
