Multilayer  Pipe Market

KWD-globalpipe, 2008-04-01, No.275. In our issue no. 274 we wrote that EMMETI are about to set up production of multilayer pipe. Meanwhile, EMMETI have asked us to withdraw this statement as it is wholly unfounded. While some considerations have been made regarding such a production EMMETI are still puzzled by the high investment needed, the numerous Italian competitors, and the extremely high production capacity for multilayer in Italy. We are happy to oblige and publish this rebuttal. Watch this space.

NSF Advises Consumers Not to Use Saudi Industries’ Piping for Drinking Water Applications

NSF International, today announced that it has revoked Saudi Industries for Pipes Company Limited’s (SIP) certification, a manufacturer of PVC pipes and fittings based in Jeddah, Saudi Arabia. Consumers should not use SIP’s Chlorinated Poly Vinyl Chloride (CPVC) piping for potable water use as recent testing indicates that this piping exceeds the maximum allowable extraction level for lead.
The piping in violation was manufactured between March 2007 and October 2007, and was marketed under the trade designation CPVC pipes in ½ inch to 2 inch diameters. The violation was uncovered during SIP’s annual audit. NSF’s numerous attempts to gain access to the plant for follow-up actions were denied. (more…)
