Due to the additional effects of temperature, the pipe clamps and clamp bases are the most vulnerable components of the support chains in heat conducting piping.
At the same time, the insulation surrounding them makes regular inspection very difficult. As these components are therefore considered to be critically important, particular attention must be paid to their design and quality.
Saiho pipe clamps and clamp bases herald a new generation of pipe surrounds and their key feature is exacting stress-related design:
coverage of a range of up to OD 48'' and 169 kip with standard types
designed for 200,000 hours fatigue life and temperatures up to 1200°F
compatibility of connections and load groups within the Saiho modular system
verification tests by independent authorities
