What equipment is used to ensure a pipe is at the correct angle before welding?

Using a level is essential for ensuring that a pipe is positioned at the correct angle before welding. When working with pipes, achieving precise angles and alignment is crucial for both the integrity of the weld and the overall performance of the piping system. A level provides a quick and reliable means of determining whether the surface of the pipe is horizontal or vertical.

The use of a level allows pipefitters to make necessary adjustments before welding takes place, which prevents issues such as misalignment and can affect the efficiency and safety of the installation. Proper leveling is important for systems that involve gravity flow, where even a minor angle deviation can lead to drainage or flow problems.

While clamps and measuring tapes are useful tools for securing pipes and measuring lengths, respectively, they do not specifically provide information about angular alignment like a level does. A surveyor's transit is generally used for more extensive site layout and elevation measurements rather than the specific angle checks required in pipefitting. Hence, the level stands out as the most directly applicable tool for ensuring correct angular alignment before welding.
