Product Q&A

Q:What is the scope of ASTM A403?

ASTM A403 covers wrought austenitic stainless steel butt-welding fittings for pressure piping and corrosion-resistant service. It applies to elbows, tees, reducers, caps, and stub ends manufactured from seamless or welded pipe. Grades include WP304/L, WP316/L, WP321, WP347, and duplex grades.

Q:What is the dimensional standard for a 90 LR elbow?

ASME B16.9 governs dimensions. For a 90 Long Radius elbow, center-to-end dimension = 1.5xNPS (nominal pipe size). Example: NPS 6 = 9 inches center-to-end. Short radius (1xNPS) is covered under ASME B16.28, not B16.9.

Q:What is the difference between WP304L and WP316L elbows?

WP316L contains 2-3% molybdenum , providing superior pitting and crevice corrosion resistance in chloride environments (e.g., marine, chemical, pharmaceutical). WP304L (no Mo) is suitable for general corrosive service but not seawater or high-chloride conditions. Both have maximum carbon 0.03% for weldability.

Q:What marking is required on ASTM A403 fittings?

Per ASME B16.9, each fitting must be marked with: manufacturer name or trademark, ASTM A403, grade (e.g., WP316L), schedule (e.g., SCH 40S), size (NPS), and heat number . For NPS 4 and smaller, markings may be on a tag attached to each bundle.
