18 Angles

A piping system is the assembly of instruments, valves, fittings, and pipes that allow for the transfer of fluid or gas from one location to another. The pipe itself is the backbone of the system.

Whatever type of piping- there will be a system and a need to ‘fit up’ the pipes. This is something a Pipe Fitter would do. Here is an example…

3 Piece 90°(3 piece turn)
3 PIECES = 2 CUTS
90÷2= 45

When building a two-piece 90° turn we need to cut two pieces at 45°. When making a three-piece turn we will need to add one more piece of pipe and thus change the angle we need to cut. The plan view of the joint will look like this. A bisected joint to show what the finished angle will be.

Types of Angles

• Acute – Less than 90˚
• Right  – Exactly 90˚
• Obtuse – More then 90˚, less then 180˚
• Straight – Exactly 180˚
• Reflex – Greater then 180˚
• Full rotation  – Exactly 360˚

An angle can be measured precisely using a protractor, precisely. An angle is measured in degrees, hence it is called ‘degree measure’ One complete revolution is equal to 360 degrees, hence it is divided into 360 parts. Each part of the revolution is a degree.
