TC Bend
What are TC Bends?
TC Bend (Tri-Clover Bend) is a type of sanitary pipe fitting used to change the direction of flow in hygienic process systems. Commonly made from stainless steel, TC bends ensure smooth, crevice-free transitions ideal for clean-in-place (CIP) operations. They are widely used in industries that demand sterile and contamination-free fluid transport.
Asiad Steel Industries is a leading manufacturer and supplier of TC Bends in various angles and sizes for hygienic process piping.
