A plumbing pipe is an U-shaped piece of pipe that is designed to hold gas or liquids to block unintentional flow. It is the most important thing to prevent the gas from sewers that enter buildings , while permitting waste materials to flow through.
In refineries that use oil traps are employed to keep hydrocarbons and other hazardous chemicals and gases from flowing through drains.
Heating systems use this technique is used to avoid thermo-siphoning, which could allow warmth to flow to places which it's not intended to be. In the same way, certain pressure gauges are linked to systems that use U bends to ensure an in-place gas, when the system is using liquid. To add a decorative look they are often disguised as complete loops of pipe making more than one U to increase the effectiveness.
In residential applications traps are usually U, S, Q or J-shaped pipes that are located beneath or inside the plumbing fixture. A trap with an S-shape is called an S-bend.
It was created by Alexander Cumming in 1775 but it was named the U-bend in the wake of the introduction of the trap with a U-shape created by Thomas Crapper in 1880.
The U-bend was not able to jam, and unlike the S-bend it didn't require an overflow. For the United States, traps are often referred to as P-traps.
