Pipe is round material that is defined by specific O.D. (outside diameter) and I.D. (inside diameter) measurements and the pipe schedule thickness. For example, an appropriate description to specify a pipe size would be, “I would like a 1-1/4 inch schedule 40 pipe elbow.” It is important to understand that a 1-1/4 inch pipe does not have a 1-1/4 inch I.D.; rather, it has a 1.38 inch I.D. based on a schedule 40 thickness.
To order pipe handrail components:
· Specify the pipe size
· Specify the schedule thickness (40, 10, or 5) see table
· Specify degree of bend (90º, 45º, etc.)
· Specify material type
If you don’t know the pipe size you can:
· Specify O.D. (outside diameter)
· Specify I.D. (inside diameter)
· Specify schedule thickness (40, 10, or 5)
Pipe Flanges have two construction types: Flat Base and Raised Base.
Where pipe posts are set on wood, concrete, walls, or stairs, Flanges can be used as slip flanges with or without a set screw. Flanges can be welded to pipe posts or anchored with set screws or expansion bolts.
