Though modern treatment plant piping systems are made of different materials, metal remains one of the most common options. in areas where pipes pass through walls, at intersections, etc.). Stenciled markings should include numbers along with flow abbreviations and arrows to indicate the flow direction where necessary (e.g.Specifically developed to indicate unit numbers, stenciled markings should contrast with the background color. Appropriate stenciled marking should be used in conjunction with color coding standards.When different coating systems are used, it’s important to choose a uniform color.
Additionally, the name of the substance should be written on the pipeline. light gray and medium gray), a six-inch band of a contrasting color should be applied to one of the pipes/systems (e.g. When two similar colors are selected (e.g. For gases or liquids not listed above, it’s advisable to use a unique color scheme.To ensure a precise, easy, and rapid identification of the gases or fluids flowing through piping systems, the following guidelines should be considered: General Instructions for Proper Color Coding of Treatment Plant Piping Systems Light Green with Yellow Band sulfur dioxide To clarify the procedural aspects relating to color coding standards for treatment plant piping systems, we’ll use this blog post to review the recommended identification color codes along with a summary of instructions.Ĭolor Coding Standards for Treatment Plant Piping SystemsĪll new and modified treatment plant piping systems should be color coded according to the following scheme: Though standard piping color codes have been developed for water and wastewater treatment plants, not all plants follow the same recommendations, causing a great deal of confusion. Adopting and maintaining proper color codes for treatment plant piping systems according to ANSI guidelines can help you avoid potential operational errors and workplace accidents by allowing your staff to identify the contents of all pipelines easily, quickly, and accurately.
