工程常见问题
The listed NPS and OD refer to the large (run) end. Small end size follows the common one-step reduction for that line class—confirm both ends on the isometric when ordering.
Yes. See the eccentric reducer chart; flat side orientation must be shown on the drawing or MTO.
H is the overall end-to-end length of the concentric reducer per ASME B16.9, used for pipe rack layout and shipping volume estimates.
Yes. Specify SCH 80 on both ends or mismatched schedules if the line list requires it.
