Insulation stent. The insulation bracket spacing according to the pipe wall thickness and the transport medium, regular support spacing of 1.5-2 m. 2. Through the competent ends, two sets of bracket mounted side by side, middle distance uniform installed according to design requirements. 3. Caliber, anti-corrosion layer external reasons, the bracket gap range 2-40mm gap are qualified. 4. Insulation bracket installed in the pipe of different diameters, so the radian because of their own toughness with the pipeline outside the arc to change. 5. Type A stent such as 508,559,610 smaller diameter piping is installed, the pipeline radians, as difficult to install can use installation tools, such as tensile calipers.
