The limitation on the length of pre assembly when installing galvanized air pipes on the head after pre assembly on the ground is to prevent damage to component interfaces caused by bending due to the weight of the galvanized air pipes.
The axis is vertically installed through galvanized air ducts. Due to the small space and inconvenient maintenance in the future, galvanized air ducts are generally connected by jacket angle steel flanges to increase the firmness and strength of the connection points and transform the flange into a "well" shape. The hanger is directly suspended on the angle steel flange on the lug without additional support.
Production and installation method of vertical installation support components for non flange connected glass fiber composite sheet galvanized air ducts.
Apply adhesive to the mortise and tenon joints of galvanized air ducts to improve the strength of the joints.
Protective measures should be taken to prevent damage to galvanized air pipes during transportation.
The galvanized air duct end of fiberglass composite plate is used to cut the surface. Before assembly, the flange connector should be sealed with tape or glue to cut the surface to prevent exposure and flying of fiberglass.
The hammer shaped device has high strength, small opening, and good performance. The raw materials used for long-term use are all produced by bending rollers. When the complement is heard on the outside and inside, there will be secondary tearing. The on-site production of cutting and drilling equipment is simple, labor-saving, and time-saving with 85 pieces. Galvanized air duct equipment shall not be protected after completion. Reduce Protection Fund No. 11. The long side diameter or bottom dimension of the mirror zinc plate air duct horizontal device is less than or equal to 400mm, and the spacing is not more than 4m; For galvanized air duct branches and hangers larger than 400mm and not larger than 3m, the spacing can be extended to 5m and 3.75m; The spacing between galvanized steel plate flanges and frames shall not exceed 3m.
The selection mode and standards for the strength of infrared pipeline supports and hangers should comply with GB ATLS and standards. The spacing between the air vent, valve, maintenance door, and self-control mechanism of the special galvanized sheet air duct support and hanger, as well as the air vent or plug, should be intact and bright after machining. The stress of each auxiliary support and hanger can be used for the disassembly or hoisting of vibration impact support and hanger上一篇：空调通风管道系统清洗流程要注意什么？
