WEB EXCLUSIVE Montreal-based PVC pipe producer Ipex Inc. recently became the second processor in North America to make oriented PVC pressure pipe for municipal water and sewer applications. Ipex had announced plans to make the pipe last year. Its Bionax OPVC pipe is 40% lighter than standard PVC pipe and almost twice as strong (7100 psi of Hydrostatic Design Basis vs. the usual 4000 psi), with three times the impact strength and better crack resistance, Ipex says. Flow rates are also higher because of larger IDs. Ipex orients its Bionax pipes in-line, using the latest technology licensed from Wavin BV in Dedemsvaart, the Netherlands, and equipment built by Rollepaal BV, also in Dedemsvaart (U.S. office in Glen Burnie, Md.). The process pulls hot pipe in the MD direction, then stretches it over a mandrel to increase TD diameter and hoop strength. Bionax pipe comes in 4 to 12 in. diam. and meets ASTM F1483 and AWWA C909 standards for pressure pipe, certified by NSF International, Ann Arbor, Mich. JM Eagle, headquartered in Los Angeles, is the only other North American producer of OPVC pipe in 6 to 16 in. OD.
