This Dixon B31W series polished weld concentric reducer sanitary fitting is made of stainless steel 316L and welds to tubing on both ends. This concentric reducer fitting welds to two pipes or tubes of different diameters that are along the same pipe axis. It is made of stainless steel 316L for strength, enhanced resistance to corrosion, and greater ease in welding than stainless steel 304. The lower carbon content of the material minimizes harmful carbide precipitation due to welding. This fitting has a maximum operating pressure rating of 250 pounds per square inch (psi) at 70 degrees F ambient temperature and meets 3-A Sanitary Standards Number 63-03 for sanitary fittings (authorization number 621). This polished weld concentric reducer sanitary fitting is suitable for use in food, beverage, and dairy applications.
Pipe and tube fittings are components used for connecting, terminating, controlling flow, and changing the direction of piping in many different industries. Sanitary fittings are used in the food, beverage, biotech, pharmaceutical, and other sanitary process industries to transport fluids through pipe lines and are available in a range of materials, finishes and shapes. When purchasing fittings, consider the application, as this will affect material type, shape, size, and required durability. Fittings are available threaded or unthreaded, in many shapes, styles, sizes, and schedules (pipe wall thickness).
