45 Degree Sanitary Welded Elbow | 304/316L Polished Pipe Fitting

I：Brief Introduction (Application, Advantages & Applicable Industries)

Our 45 degree sanitary welded elbow is a hygienic pipe fitting for changing fluid direction at 45° in sanitary pipeline systems. Made of 304 / 316L stainless steel with mirror internal & external polishing, it eliminates dead corners, avoids material residue and bacterial growth. It complies with DIN11850 and ASTM A270 standards, widely used for food, dairy, beverage, brewery and pharmaceutical fluid transfer pipelines.
