AI Technical Summary
Technical Problem
Existing fire collars are difficult to install in densely packed corners of pipes, especially in confined spaces where flexible adjustment and stable fixation are challenging.
Method used
The fire arrestor ring is divided into several sections, which are connected by movable hinges to achieve flexible bending. Fixed bolts form a rigid support, and stainless steel fasteners and fixing components ensure stable installation in confined spaces.
Benefits of technology
It enables flexible adjustment of pipe angle deviation in confined spaces, ensuring that the fire collar does not shift during a fire, maintaining structural strength and fixation.
