Return Black Paint Seamless Buttweld FAQs
Q
What is the Function of Return?
A.
Return, also called 180°Elbow, helps change direction at 180 degrees since it usually results in low pressure. Its application is limited to minimal deposition and low turbulence systems.
Q
What is Schedule 40, Sch80?
A.
Schedule, often shortened as such, is a North American standard that refers to the wall thickness of a pipe or pipe fitting. Higher schedules mean thicker walls that can resist higher pressures.
Pipe standards define these wall thicknesses: SCH 5, 5S, 10, 10S, 20, 30, 40, 40S, 60, 80, 80S, 100, 120, 140, 160, STD, XS and XXS. (S following a number is for stainless steel. Sizes without an S are for carbon steel.)
Higher schedules are heavier, require more material, and are therefore more costly to make and install.
