Plastics lined steel piping for safe transport of contaminating products includes a chamber containing water surrounding the lining and communicating with expansion vessels, for leak detection

摘要

The plastics-lined steel piping for safe transport of contaminated products has its steel exterior (2) separated from the plastics (1) by a chamber (3) containing water communicating with expansion vessels. The separators (5) contain water flow holes, and the protective exterior (2) can also serve as a support for e.g. a modular stabilizer, with rapid detection of leaks of e.g. chemicals.
