What is the symbol on a pipe?
In the United States, this is usually an arrow that points in the direction the contents in the pipe are flowing. A label can also have common warning symbols to alert people to potential dangers; this is common in Europe.
How to label a pipe?
The following considerations will help ensure pipe labels are visible to the people who need to see them: 1 The Frequency of Labels - Labels need to be placed at least every 25-50' on the pipe so they are easy to see. It is also important to add a label if the pipe changes direction so that it is clearly visible. 2 Obstructions to the Label - If a pipe goes through a wall or around a corner, labels should be placed on either side so that people can see the color of the label from any angle. 3 Lighting - While pipes are often in areas that don't get too much light such as under the floors or in the rafters, it is helpful to ensure a sufficient amount of light is reaching them so people can see the colors and words on the labels. 4 Near Access Points - If there are designated access points to a pipe, it is important to have a label visible. This will help the maintenance team quickly determine what is in a pipe before working on it. 5 Near End Points - At either end of the pipe, there should be a label so that people using the pipes can quickly see what is in them.
Why do pipes need to be cleaned?
Cleaning pipes on a regular basis will make labels easy to see. Even having a layer of dust on a label can cause the color to appear different than it is. This could cause someone to incorrectly assume they know what is in a given pipe, which opens them and the facility up to the potential for dangerous accidents.
Why are pipes important?
Most facilities have dozens of pipes moving substances from place to place and because of this, it is important to be able to keep track of the contents in each pipe as well as its destination.
How to make sure people know what each color label means?
One of the most effective ways to make sure people in the facility always know what each color label means is to hang up pipe color code charts. These are effective because employees can reference them before taking any action. This is especially important for employees who don't often need to access pipes and may not remember the color code in detail.
Why is it important to use user defined pipes?
This is important because it allows facilities to plan out certain pipes that don't fit in with the normal standards. It is important to remember, however, that whenever using user-defined pipe markings, people who haven't been sufficiently trained won't understand what they mean.
What is piping code?
