A combination of elbows or bends that brings one section of piping into parallel with another section of piping is known as?

The term that describes a combination of elbows or bends used to bring one section of piping into parallel with another section is known as an offset. An offset is a crucial element in plumbing design as it ensures that pipes can navigate around obstacles or fit within the specifications of a given layout while maintaining the required flow and pressure.

In plumbing systems, offsets help to redirect the flow of water, taking into account the necessary angles and dimensions of the piping system. This type of configuration is essential in maintaining alignment in situations where a direct run of piping isn't possible due to structural elements or other constraints.

The other terms—curve, fitting, and joint—do not accurately describe the specific scenario of aligning parallel pipe sections. Curves in plumbing generally refer to rounded changes in direction not specifically about parallel alignment. Fittings are generic components that include various types of connections, and while an offset uses fittings, the term "fitting" doesn't convey the specific concept of establishing parallelism in the piping layout. A joint refers to the connection where two pipe ends meet and does not pertain to the formation of parallel runs. Understanding the distinct terminology is vital for effective communication and function within plumbing systems.
