工程常见问题
Eccentric reducers keep the flat side continuous with the bottom of horizontal pipe runs to avoid air pockets or drain traps, common on pump suction and gravity lines.
Mark FUP (flat up), FOP (flat out), or flat bottom on the isometric or MTO. Fabrication will align the flat per the drawing.
Overall length H is similar for the same large/small NPS pair, but centerlines offset. This table lists large-end NPS and reference H for layout.
Any B16.9 combination can be quoted with large end, small end, schedule and orientation on the inquiry.
