The ASTM A403 WP304 45° Butt Weld Elbow is a precision-engineered directional fitting designed for critical piping systems requiring superior corrosion resistance, cleanliness, and structural integrity. Manufactured from premium 304 stainless steel, this elbow ensures optimal flow direction change while maintaining system pressure and efficiency.
Material Certification: 304 Stainless Steel (UNS S30400), Cr 18-20%, Ni 8-10.5%
Manufacturing Standards: ASME B16.9 / MSS SP-43 Class 1 compliant
Pressure Ratings: Schedule 5S, 10S, 40, 80, 160 (available on request)
Size Range: DN15 to DN600 (1/2" to 24")
Wall Thickness Options: Standard, Extra Strong, Double Extra Strong series
Surface Finishes: Pickled & Passivated, Mechanical Polish (180-600 grit), Electropolished
Testing Protocols: 100% dimensional inspection, optional PMI, Liquid Penetrant Testing
Superior Corrosion Resistance: 304 stainless steel provides excellent performance in oxidizing environments across chemical, food, and pharmaceutical applications
Leak-Free Connection: Butt welding creates permanent, full-strength joints that eliminate leakage points
Optimized Flow Design: Precise 45° angle minimizes turbulence and pressure drop for enhanced fluid dynamics
Stress Relief Treatment: Solution annealing (1050-1100°C rapid cooling) removes welding stresses and restores corrosion resistance
