Technical Notes

Weight values are approximate theoretical reference values based on ASME B16.9 standard dimensions.
Actual product weight may vary depending on manufacturing tolerance, configuration, and specific material density.
Weight may vary according to material grade, schedule, and dimensions.
For threaded and forged fittings, standard formulas are unreliable; always refer to manufacturer data sheets for critical engineering calculations.
Always verify critical dimensions and weights against the applicable standard or approved drawing before fabrication.
