Ventilation duct is a piping system software used for gas transportation and distribution. There are two kinds of compound air duct and inorganic air duct. Durkduct is a composite duct. It can be classified according to cross section and material. What provisions must be provided for air duct installation? 1. Ventilation duct machinery and equipment in Hunan Province ranks second: first the main pipe and then the riser pipe. Method of machinery and equipment: to judge according to the specific situation. The length can be connected on the road surface, and then all the personnel can be hoisting. It can be matched to the last 10-12 meters long. The ventilation duct can be hoisting to the support frame (the heavier ventilation duct) with the chain or lifting platform, and the ventilation duct can also be put on the support frame section by section. 2. Professional skills stipulate that the flatness of dark installation is less than or equal to 3 mm per meter, and the total errors and leaks are less than or equal to 20 mm; Flatness per meter ≤3mm, total errors and leaks ≤ 20mm; Buried, the direction should be appropriate, no significant errors. 3. The joint of the ventilation duct of the composite material should be firm, without holes and cracks. After the completion of the software and equipment of the ventilation duct system, the air tightness test should be carried out according to the system software type. 4, ventilation ducts through the regeneration must be turned off fire safety explosion-proof wall or concrete floor, should be embedded pipe or safety protection waterproof casing, the thickness of stainless steel should not be less than 1.6 mm, ventilation ducts and safety protection waterproof casing, the use of non-combustible and non-harmful soft materials to plug leakage.
