Customized processing of air conditioning duct wooden bracket

Customized processing of air conditioning duct wooden bracket

The standard size of 426 * 50 type insulation has a thickness of 50mm, a width of 50mm, a bracket base length of 526mm, and a distance of 50mm from the pipe end to the support hanger after installation. The 426 * 50 type air conditioning wooden bracket is mainly used for the installation and support of galvanized pipes, seamless pipes, welded pipes, PPR pipes, and DN400 type pipes in pipeline systems. Φ27、 34, 43, 48, 60, 76, 89, 108 are used for fixing and installing PPR air conditioning ducts, and can be used as iron clips for fire and chemical pipelines.
4>Φ273、 325, 377, 426, 480 are used for fixed installation and scaffolding of main and underground pipelines. Knowledge Expansion and Extension: (1) Stacking of Materials
1) Plates of the same thickness should be stacked in the material pile.
2) If the length of the board is uneven, the long board should be stacked on both sides of the stack, and the short board should be placed in the middle. 3) A spacer strip should be placed between two layers of boards, with a cross-sectional size of 25 × 25mm and a length equal to the width of the stack. The upper and lower spacers should be aligned, and the spacers at both ends of the stack should be level with the ends of the board.
4) A heavy object should be placed at the top of the stack aligned with the position of the divider to prevent warping of the board or stacking low-quality boards at the top. 3.1 The Quality Management Department is responsible for formulating the implementation rules for pipeline deformation prevention and control in long-distance pipeline engineering, supervising the implementation of these rules at the construction site of long-distance pipelines, and guiding the Quality Supervision Station to supervise and inspect the implementation of pipeline deformation prevention and control measures in the project department.
3.2 When conducting quality supervision and inspection on long-distance pipeline engineering projects, the quality supervision station focuses on examining the factors that cause pipeline deformation and the construction process. It particularly checks the implementation of pipeline deformation prevention and control measures for welding, trench excavation, pipe laying, cleaning and diameter measurement processes by the pipeline group, and inspects the physical quality of the pipeline by checking the deformation of the diameter measurement plate

Φ27、 34, 43, 48, 60, 76, 89, 108 are used for fixing and installing PPR air conditioning ducts, and can be used as iron clips for fire and chemical pipelines.
4>Φ273、 325, 377, 426, 480 are used for fixed installation and scaffolding of main and underground pipelines. Knowledge Expansion and Extension: Thirdly, the steel pipe welding sub item is applicable to the welding of welded steel pipes, seamless steel pipes, and other steel pipes.
4、 The sealing material for pipeline threaded connections takes into account both hemp and PTFE tape, but in reality, it is different and cannot be adjusted.
5、 The installation of outdoor plastic water supply pipes has comprehensively considered the connection methods such as bonding, electric welding, rubber rings, and threaded connections. When applying the sub items, the materials of the pipes and fittings can be converted according to the actual situation. But when using rubber ring connection, the rubber ring material should be calculated according to the actual situation; When using electric fusion welding, the material of the electric fusion sleeve should be calculated according to the actual situation. (5) Final treatment (final treatment, final treatment): Final treatment is carried out after the wood has been balanced or after the actual moisture content of the wood that does not require balance treatment reaches the required final moisture content.
Dry bulb temperature: 5-8 ℃ higher than the dry bulb temperature in the post drying stage, but not exceeding 100 ℃.
Wet bulb temperature: 3-4 ℃ lower than the dry bulb temperature during processing. If a balanced moisture content device is used, the balanced moisture content value can be set to 13% -14%.
Retention time: You can refer to the initial processing time, or shorten it by 1-2 hours compared to the initial processing time.
The effectiveness of the final treatment should be based on the actual inspection of whether the residual stress index of the wood meets the requirements of the grade wood quality standards. For secondary materials that are not cut after drying, a certain residual stress is allowed, and the final treatment may not be strict
