A stainless steel sanitary elbow fitting is a pipe fitting that connects two pipes of different or the same nominal diameters and changes the direction of fluid flow. They are found in various connectiond (weld or tri-clamp) and sizes, including bend radius of 90° and 45° angles. Weld elbows are used on permanent installations where process piping and equipment can be cleaned in place (CIP) and removal from the system is not required.  They are often used at turns in pipelines to ensure a smooth flow of fluids. Sanitary elbows are designed to prevent deposits from forming and meet hygienic requirements. They can also help improve product quality and safety by minimizing contamination. They're commonly found in pharmaceutical, food and beverage, personal care, and dairy industries. Made from stainless steel (usually 304 or 316L), they’re autoclavable, corrosion-resistant, and have antimicrobial properties.
