工程常见问题
Per ASME B16.9, A for 45° LR elbows is shorter than 90° LR on the same NPS. Values in this table are reference layout dimensions in millimeters for spool design.
Yes. SCH 80 wall and weights differ; see our SCH 80 elbow chart or list schedule on the inquiry.
Standard export supply includes ASME B16.25 bevel for field welding unless the PO specifies socket or threaded ends.
Masses are approximate single-piece carbon steel values for freight planning. Certified weights may appear on packing lists after final inspection.
