Which way does PVC pipe go?
The flow surface on the interior of a PVC pipe is a smooth surface interrupted by a small gap at every joint. For flow in the spigot-to-bell direction, the flow encounters a square edge as it crosses the gap. For flow in the bell-to-spigot direction, the flow encounters a slightly rounded edge as it crosses the gap.
Why are pipe ends important?
While size is an important factor when choosing flanges, elbows, and other components of your piping process, pipe ends are a critical consideration to ensure a proper fit, a tight seal, and optimal performance.
Where is the plain end of a pipe placed?
Where applicable, the plain end will be placed typically ⅛” from where the pipe rests to allow for thermal expansion during welding.

Can a pipe have multiple end types?
A single pipe can also have multiple end types. This is often designated in the pipe description or label.
Flanged Pipe
No Bell pipe is made in Class 53 or higher in order to meet AWWA C115/A21.15 for flanged pipe. Flanged pipe is used in many applications, including treatment plants and pumping stations. For water applications, No Bell for fabrication purposes is typically provided with double cement lining which is standard for fabricated pipe.
Grooved Pipe
No Bell pipe is cast with a minimum Class 53 for grooved pipe in accordance with ANSI/AWWA C-606. Grooved pipe is used for water, sewage, and other liquids, where specifiers prefer something different than flanged pipe. This pipe has grooved pipe ends, which are connected using segmented mechanical couplings and bolts.
River Crossing Pipe
No Bell is usually cast in Class 55 or 56 for use as River Crossing pipe for the additional weight to help overcome buoyancy. For a great article describing an inventive way to complete a difficult river crossing, check out this blog, "Another River to Cross" by my colleague Ken Rickvalsky.
