Tri Clamp is a type of clamp produced according to the ISO 2852 standard and widely used for connecting sanitary pipes. 

The ISO 2852 standard specifies the size, shape, material requirements, and testing methods for connection force of clamps to ensure the safety and hygiene performance of the connection.

The design of Tri Clamp clamps makes them easy to install and disassemble, and can meet the high hygiene requirements for pipeline connections in industries such as food, pharmaceuticals, and chemicals. 

It is usually made of stainless steel(SS316/SS316L), which can resist corrosion and contamination, while its smooth surface design helps reduce bacterial growth(usually Ra<0.8μm).
