There are attached tables such as air duct, fixed support and support frame in the smoke exhaust pipe. Its installation is divided into two parts. One part is air duct, including common flange air duct and hot-dip galvanized electric welding air duct, and the other part is fixed support and support frame. These two parts have the following details.
1. Air duct
(1) The installation of bronchitis must be carried out after the construction of the enclosure of the construction project, and the detailed address has long been eliminated.
(2) Before setting the pipeline, it is necessary to study the position, average altitude, direction, etc. in order to better complete the scheme design requirements, ensure that the position of the hole is as appropriate as possible, and the specification of the hole is as much as 100 mm above or below the specification and model outside the pipeline.
(3) When dealing with bronchitis, collision or falling must be prevented to prevent damage to bronchitis. Remove dust and dirt before installation. If the whole process of installation is interrupted, the air duct mouth should be closed to prevent dust and unclean things from entering the air duct.
(4) Bronchitis is not allowed to install web pages on walls or wooden floors, or install throats, cables and cables.
(5) In case of inflammable gas in the gas transmission pipeline, or in such geographical environment, if it is necessary to choose the indispensable grounding system precautions to safely prevent the steam body whose temperature exceeds 80 ℃, please choose the indispensable safety precautions.
(6) Shandong ventilation pipe processing personnel reminded that sealing treatment should be carried out as far as possible to prevent seamless splicing at the bottom of the pipe. wait.
2. Seismic support
(1) The application of common raw materials of all parts and components of the seismic support shall comply with the provisions of the design scheme and its main parameters.
(2) The large allowable installation interval of the pipeline, and at least the model and specification of the support should meet the requirements.
(3) The embedded parts of the seismic support shall be installed properly, firmly and reliably. The embedded parts shall be removed, and the exposed part shall be corrosion resistant.
(4) Never set the fulcrum support frame at the operation process part of the mechanical equipment. When fixing the fixed fulcrum support frame, the anchor screws with the overlapping length of bulging reinforcement shall be used to fix it, and the anchor screws with the overlapping length of bulging reinforcement shall be used to meet the specified requirements as far as possible.
That's all for the installation instructions of ventilation duct, air duct and seismic support. If you are interested in this, please follow our website http://www.jnqsg.com Ask for more precautions.
