Cpvc pipes, fittings and tubular conduits in marine vessels

Abstract

A marine vessel (100) includes pipes and tubular fluid conduits which are a part of a waste water management system (102). The waste water management system includes CPVC piping (104) that is used to transport at least one of black water or gray water. The CPVC piping meets at least one fire endurance test set forth by the International Maritime Organization. Additionally or alternatively, the CPVC piping meets at least one test set forth in IMO A.653 (16).

Description

technical field [0001] The present invention relates to fittings, tubes and tubular conduits that can be classified in U.S. Class 138. Background technique [0002] Clean global water supplies have become a high priority for many governing bodies that impose strict environmental controls on those doing business on land or at sea. In offshore applications, considerable volumes of wastewater can be generated. Wastewater generated in offshore applications can include contaminants such as coliform bacteria, Cryptosporidium and Giardia, suspended solids, etc., all of which can have detrimental effects on water quality and the environment in general. As a result, various marine sanitation methods, devices and systems are used to mitigate the environmental impacts associated with wastewater. Example marine sanitation methods include physical / chemical separation methods, biological treatment methods, and electrolytic treatment methods. [0003] Physical / chemical separation includ...
