Flange insulation jacket installation method and construction precautions
Flange insulation jackets are commonly used in industrial thermal insulation and play a very important role in the insulation process of equipment. Today, the editor will talk about the large installation method and construction precautions for the flange insulation jacket. I hope to help everyone. The details are as follows.
Flange insulation jacket installation method and requirements
Furnace rust removal → Weld the flange insulation jacket bolts on the furnace wall plate → remove the flange insulation jacket → screw the guide rod onto the small head of the screw → pass the flange insulation jacket through the guide hole along the center hole Rely on the furnace plate → use a special wrench to screw the nut onto the screw → unscrew the guide rod → install the other flange insulation jackets in turn → pull out the flange insulation jacket central plastic tube → disassemble the flange insulation jacket bundle With belt → compression mounting flange insulation jacket → install the next row of folding modules
Installation requirements:
1. First install the flange insulation jacket, then construct the flange insulation jacket
2. Installation of furnace wall flange insulation jacket should be installed from the bottom upwards
3. Anchoring nail welding position should be accurate, strict control error
4. Install the furnace top module first, then install the furnace wall
5. The arrangement of flange insulation jackets is mostly in the same direction "side-by-side" arrangement. After installing a row of modules, the flange insulation jacket should be compressed as required.
6. The connection between the top and the wall and the wall and the wall shall be compressed with a flange insulation jacket.
Flange insulation jacket construction precautions
Anchor nail welding
1. The anchoring nails must be welded perpendicular to the furnace wall. The deviation of the adjacent center distance of the bolts is ≤ 2mm, and the deviation of any two spacings is ≤ ± 3mm.
2. When wiring, it is necessary to use the center line of the wall as the reference, and route to both sides. The bolt position mark is made strictly according to the design drawing. The cumulative error of the size that may appear in the actual line is reflected in the last row of bolt positions.
3. The welding must be firm, the welding is completed, the quality of the welding is checked by hammering and bending one by one, and the welding slag is clear.
4. Must pay attention to the thread protection of the anchor bolts.
Backing layer tile
1. The indirect seams of the jacket must be staggered, and the amount of staggering is not less than the drawing.
2. Must be compressed to the required thickness in strict accordance with the design requirements
3. Fast cards must be clamped to prevent bounce
Module installation
1. When arranging the ranks, pay attention to the installation of the compensation bars between the rows and the rows. When installing, strictly follow the design requirements of the drawings and compress them to the specified thickness.
2. Install one by one, row by row, make sure the nut is tightened in place
3. After pumping the guard plate and the center plastic tube, you must carefully check the hole at the casing and the gap between the modules, especially the corners.
4. In order to prevent falling off, the compensation strip must be fixed to the installed flange insulation jacket with a U-shaped nail.
The above is about the installation method and construction precautions of the flange insulation jacket. I hope that everyone can understand the installation method and construction precautions of the flange insulation jacket.
