Ventilation ducts are indispensable in building construction. When making and installing pipelines, certain standards shall be followed to ensure the normal application of the completed pipelines and reduce the probability of common faults. What standards should be followed in production, manufacturing and installation?
1. The production, manufacture and installation of air duct shall be carried out in accordance with the requirements of design drawings, contracts and relevant standards and specifications. All changes must be accompanied by design scheme or contract change notice or technical permit visa.
2. Before the construction of air duct system software engineering, the construction enterprise shall be in harmony with the construction unit, construction unit, general contractor, design scheme enterprise, etc. Check the installation status of embedded holes for the parts of air ducts and other pipelines. The project construction shall be in harmony with civil construction and other professional technical types of work.
3. The raw materials of common plates, aluminum profiles and other key finished products used in the manufacture and installation of air ducts shall meet the requirements of the design scheme and relevant products' Executive Standards in China, and shall be verified by the inspection of the original factory. The project acceptance of raw materials shall be carried out in accordance with China's current standards and relevant specifications.
4. The finished ventilation duct must have the corresponding enterprise qualification certificate, including the material qualification certificate of key raw materials, the compressive strength and tightness test report of air duct (the non-metallic air duct must also be provided with the qualified report of fire control and environmental sanitation test).
5. The production and processing technology of environmental protection, energy conservation and mechanical automation shall be selected for the production and manufacturing of air duct.
6. The testing instruments and instruments commonly used in the production, manufacturing and installation of air ducts shall be in qualified condition and within a reasonable testing period.
7. The air duct of concealed decoration works shall be subject to the project acceptance and approval visa of the project supervision staff before being concealed.
When manufacturing and installing ventilation ducts, they all have regulations they should follow. Doing this well can make all pipelines more durable.
