SGL Acotec GmbH, a member of the SGL Carbon Group that specializes in industrial corrosion protection, has developed a GRP bonded tube system capable of handling highly corrosive media at temperatures of up to 200 degrees C (392 degress F), reported KWD-globalpipe ( .

Going by the name Keraverin PTFE, the tubing is distinguished by brand-new liner material and a specially developed process system that makes it affordable. It is particularly well suited for use in the pipeline systems of chemical plants, where maximum safety and reliability are a priority. It is a seamless and largely no-flange system. Where needed, flanges of the same material are provided.

SGL Acotec views it as a substitution product for conventional metal tubes with enamel or loose-shirt lining. The process arose from a specific market requirement in which a chemical industry client asked for a technical solution for the general weak points at flanged joints of a pipeline system. Also, permeation of the liner led to corrosion of the outer steel piping.

SGL Carbon Group is headquartered in Wiesbaden, Germany, with U.S. sales office in Charlotte, NC ( The company was formed in 1992 as a merger between SIGRI (Germany) and Great Lakes Carbon (U.S.).
