工程常见问题
Ratings depend on material and schedule (e.g. 3000 lb and 6000 lb classes). Confirm class on the line specification and MTO.
ASME B16.11 commonly covers NPS 1/8 through 4. Larger lines typically use butt-weld B16.9 fittings.
Yes. A 1/16" (1.6 mm) expansion gap is standard practice before socket fillet welding per industry guidelines.
Stainless and alloy forged fittings in A182 grades can be quoted on the same inquiry.
