Clamps Overview: Types, Applications, and Specific Sizes
Clamps are fasteners used to secure and connect pipes, valves, and other equipment. Typically made of metal, they exhibit good corrosion resistance and high-temperature tolerance. Clamps achieve secure connections by tightening bolts or nuts, ensuring the stability and safety of the assembly.
In level instrumentation, clamps are essential for maintaining the stability and sealing of instruments while simplifying the installation and maintenance processes. In applications involving sanitary instruments, the clamp connection method meets hygiene standards, facilitating cleaning and maintenance. Clamps are often made from corrosion-resistant materials like stainless steel, ensuring safety and hygiene. Thus, clamps play a crucial role in the design and installation of sanitary instruments.
