1 version 1996 and 2015 are indicated below….ANSI A13. 1-2015.

Green with White Lettering – Using a green label with white lettering means that the pipe contains potable water. It could be used for cooling, feeding boilers, or even going to drinking fountains or sinks. Blue with White Lettering – Blue labels with white lettering are used for pipes that transport compressed air.

A color code or colour code is a system for displaying information by using different colors. The earliest examples of color codes in use are for long distance communication by use of flags, as in semaphore communication.

– Ensure to know the color coding of various piping systems on ship (e.g. bilge lines are normally yellow, sludge line is black, fresh water lines are blue, sea water lines are green etc.)

CPVC is widely used in water and sanitary systems for hot and cold water distribution. It is a thermoplastic produced by polymerization of vinyl chloride, with additional chlorination.

Although there are many options for underground water pipes, HDPE pipes and PEX pipes are generally the best choices for an underground water line. These durable pipes are resistant to corrosion and rusting, ideal for running an underground water line.

Copper pipes are considered by many to be the standard for residential hot or cold water applications. These lightweight and durable metal pipes are available in rigid 2- and 10-foot lengths with diameters of ½ inch to 1 inch. Types of copper pipe fall into categories based on thickness of pipe wall.

In most cases, the main pipeline from the street to your home is either 3/4 or 1 inch in diameter, supply branches use 3/4-inch-diameter pipe, and pipes for individual components are 1/2 inch. Remember that water pressure decreases by a half-pound per square inch for every foot pipes extend above your water supply.

Types of Pipes Main Plumbing Pipes. There are five plumbing pipe materials that are — or were in the case of galvanized steel — most common: copper, galvanized steel, polyvinyl chloride (PVC), chlorinated polyvinyl chloride (CPVC) and cross-linked polyethylene (PEX).

Pipes come in several types and sizes. They can be divided into three main categories: metallic pipes, cement pipes and plastic pipes. Metallic pipes include steel pipes, galvanised iron pipes and cast iron pipes. Plastic pipes include plasticised polyvinyl chloride (PVC) pipes (LEE n.y.).

Pipe fittings, also known as pipe connectors, attach one pipe to another in order to lengthen the run or change the flow direction in a plumbing system. These are used to combine, divert or reduce the flow of the water supply, and they come in a variety of sizes to fit the pipe they will connect.

Common joining methods include: Adhesive bonding, brazing, CSST, flanged, grooved, heat-fusion weld, hubless coupling, mechanical, PEX, press, quick connect, solder, solvent weld, SV gasket, threaded and welding.

What are the different types of joints?

• Ball-and-socket joints. Ball-and-socket joints, such as the shoulder and hip joints, allow backward, forward, sideways, and rotating movements.
• Hinge joints.
• Pivot joints.
• Ellipsoidal joints.

This Indian standard covers the colour scheme for the identification of the contents of pipelines carrying fluids in domestic and public buildings and such industrial installations where a specific colour code does not exist.

HTML color codes are hexadecimal triplets representing the colors red, green, and blue (#RRGGBB). For example, in the color red, the color code is #FF0000, which is ‘255’ red, ‘0’ green, and ‘0’ blue. These color codes can change the color of the background, text, and tables on a web page.

I calculated there to be 16,777,216 possible hex color code combinations. The maximum possible characters that we can have in a single hexadecimal character is 16 and the maximum possible characters a hex color code can contain is 6, and this brought me to my conclusion of 16^6.

a color name. HTML used to recognize 16 color names (“black”, “white”, “gray”, “silver”, “maroon”, “red”, “purple”, “fushsia”, “green”, “lime”, “olive”, “yellow”, “navy”, “blue”, “teal”, and “aqua”), but new browsers can recognize 147 CSS3 color names.

Safety Color Coding Labels and Tape

The color of safety

• Red: Fire protection equipment. Danger, high risk of injury or death.
• Orange: Moderate risk of injury. Guarding devices.
• Yellow: Caution statements. Minor risk of injury.
• Green: Safety equipment or information.
• Blue: No immediate hazard.
• Red – combustible materials. Yellow – oxidizers.

caution

ANSI Safety Color: Blue Blue communicates information unrelated to personal injuries and other hazards (most commonly on “Notice” signs). It is most commonly associated with maintenance work and other safety precautions. Blue signs may: Alert employees to designated smoking and non-smoking areas.

The colour should be green where the information supplements a safe condition sign, red where it supplements a fire equipment sign or yellow to supplement a warning sign.
