FAQ
Q: What makes ASME B16.9 fittings different from other standards?
A: ASME B16.9 provides precise dimensional and tolerance specifications ensuring worldwide compatibility. Any B16.9 fitting will align perfectly with standard pipes regardless of manufacturer.
Q: Can I mix your fittings with pipes from other suppliers?
A: Absolutely. The ASME B16.9 standard ensures compatibility across manufacturers when Nominal Pipe Size and Schedule match.
Q: Why are dimensional tolerances so critical?
A: Proper tolerances prevent misalignment during welding, which can cause defects, turbulence, and eventual failure from corrosion or fatigue.
Q: Are these fittings suitable for pigging operations?
A: Long radius elbows and tees work well for most pigging applications. For intelligent pigging in long pipelines, we recommend 3D or 5D bends per ASME B16.49.
