This is because it takes more energy to push them into motion than to keep them moving. In piping systems, your pipe surfaces are constantly running into heavy, fixed objects. That combination creates a high potential for friction and damage.
For instance, when a heavy pipe is stacked on a bare beam, any energy that moves the pipe is transferred into surface friction, which grinds down the outer layer of the pipe. In order to avoid friction damage, project engineers generally desire to have a low coefficient of friction. Here is the common equation for finding coefficient of friction fr :. Coefficient values are the numbers that express how materials interact.
These values usually run from , but they can also be higher than one if the materials are especially sticky. If materials have a coefficient value of one, it means the friction force is the same as the normal force. In other words, the force required to move the object is equal to that object's weight.
Objects can also have a friction value higher than one. For instance, rubber is a common material that can have a particularly high coefficient of friction. In piping, a lower coefficient of friction generally amounts to less wear. Imagine if your pipes were being scraped against concrete.
Pipe supports with a low coefficient of friction can protect pipes from damage by keeping the metal of pipes from scraping against rough surfaces around them. Pipes need to hold up in the face of several different forces. Gravity pulls down on heavy materials in one direction, rushing liquids push in another direction, and thermal expansion can cause even more movement.
All of these forces can focus damage on a single area at high-friction points. As a pipe wears down, it can weaken, rupture, and burst. Pipe supports that reduce the coefficient of friction lower the impact on pipes. They allow pipes to move more naturally without being torn apart. When metal surfaces wear down and split open, corrosive materials can slip into crevices and cause corrosion.
From there, corrosion can spread throughout a system and weaken pipes.
