What is the angle of a 1/8 pipe bend?

30 degrees
45 degrees
60 degrees
90 degrees

The correct answer is: 45 degrees

The angle of a 1/8 pipe bend is 45 degrees. In plumbing and piping, different bends serve to redirect the flow of liquids or gases within a pipe system. The term "1/8 bend" specifically refers to the fraction of a full circle that the bend represents. Since a full circle is 360 degrees, an 1/8 bend corresponds to one-eighth of that total, which is calculated as 360 degrees divided by 8, equating to 45 degrees. This understanding is crucial for contractors and plumbers who must design and install systems correctly to ensure optimal flow and fit of piping components. It’s important to recognize that as the fractions of bends decrease (such as 1/4 or 1/3 bends), the angles increase, leading to sharper turns in the piping system. Hence, knowing the angle for specific bends aids in accurate planning and installation within construction and plumbing projects.
