　　Insulation bracket instructions

　　First, the insulation bracket spacing According to the pipe wall thickness and conveying medium may be, conventional support spacing of 1.5-2 meters.

　　Second, through the competent end of the two sets of stents installed side by side, the middle of the distance according to the design requirements of uniform installation.

　　Third, due to diameter, corrosion and other external reasons, so the scaffold gap is different, ranging from 2-40mm qualified clearance.

　　Fourth, the insulation bracket installed in the pipe on different diameter, so the arc due to their own toughness can be changed with the pipeline outside the arc.

　　5, A-type bracket in the installation of such as 508,559,610 and other smaller diameter pipe, due to the larger pipeline curvature, such as difficult to install can use the installation tools, such as stretching calipers and so on.

　　Sixth, according to the construction process requirements, casing length greater than 30 meters, in order to prevent excessive wear, the front end need to use steel support bracket, the competent through the casing, the steel support bracket can be removed and reused.

　　7, in order to speed up the construction speed can be used to fasten the power tool screws.

　　8, 800mm and above diameter pipe can increase the reinforcement zone, in order to achieve double fastening effect.

　　In order to facilitate the construction of each insulation bracket lined with insulating rubber plate, the installation without additional rubber plate.
