济南风管加工共板法兰主要由角码、法兰夹具和法兰连接，与风管连接成一体。虽然这种风管成本低(角钢消耗减少，制作角钢法兰的人工消耗减少)，但实际应用中不如角钢法兰，漏风率也大，一定用机床加工。
Jinan air duct processing plate flange is mainly composed of corner code, flange clamp and flange connection, which is integrated with the air duct. Although the cost of this kind of air duct is low (the consumption of angle steel is reduced, and the labor consumption of making angle steel flange is reduced), it is not as good as angle steel flange in practical application, and the air leakage rate is also large, so it must be processed by machine tool.
手工制造很难实现其生产，通常只用于新风系统、空调系统等。排风系统通常采用角钢法兰连接，但人防工程不允许采用普通法兰板连接，那么济南通风管道制作基础是什么?下面，让我们一起来详细了解一下。希望能帮到您。
Manual manufacturing is difficult to achieve its production, usually only used for fresh air system, air conditioning system and so on. The exhaust system usually adopts angle steel flange connection, but the civil air defense project does not allow the use of ordinary flange connection, so what is the foundation of Jinan ventilation pipe? Next, let's have a detailed understanding. I hope I can help you.
Jinan ventilation pipe processing
济南通风管道厂家发现，在加工制造风管的过程中，对材料的要求相当苛刻。当风道表层为铝箔时，为了保证表层不容易损坏，规定了铝箔的材质和厚度，规定了铝箔与增强材料复合的风道表层铝箔的厚度。
Jinan ventilation duct manufacturers found that in the process of processing and manufacturing air duct, the requirements for materials are quite harsh. When the surface layer of air duct is aluminum foil, in order to ensure that the surface layer is not easy to be damaged, the material and thickness of aluminum foil are specified, and the thickness of aluminum foil on the surface layer of air duct compounded with reinforced material is specified.
非金属风管材料发展迅速，种类繁多，因其特点和优势而得到广泛应用。为确保使用，根据工程需要，建议由这些材料制成的风管应具有不燃性或阻燃B1燃烧性能，面层一定为不燃性材料。
Nonmetallic duct materials have been widely used because of their characteristics and advantages. In order to ensure the safety of use, according to the needs of the project, it is suggested that the air duct made of these materials should have non combustible or flame retardant B1 combustion performance, and the surface must be non combustible materials.
根据我国多年的工程应用实践和产品现状，规定了热敏胶带和压敏胶带的剥离强度试验低值和铝箔厚度，要求胶带宽度不小于50毫米，以防止所用胶带不能满足管壁密封强度和风管的使用寿命。热敏胶带的优点是它依靠热熔粘合，只要不加热，粘合表面在常温下固化，并且具有牢固的粘合强度。
According to the engineering application practice and product status in China for many years, the low value of peel strength test and aluminum foil thickness of thermal tape and pressure-sensitive tape are specified, and the width of tape is required to be no less than 50 mm, so as to prevent the tape from failing to meet the sealing strength of pipe wall and the service life of air duct. The advantage of thermal adhesive tape is that it depends on hot-melt bonding. As long as it is not heated, the bonding surface is solidified at room temperature, and it has strong bonding strength.
济南通风管道是一种用于循环空气和降低有害气体浓度的市政基础设施。通风管道和风管生产安装中使用的板材、型材等主要成品应符合现行设计标准及相关产品的规定，并应具有出厂检验证书。材料进场时，应按现行标准验收。
Jinan ventilation pipeline is a kind of municipal infrastructure for circulating air and reducing the concentration of harmful gases. The main finished products such as plates and profiles used in the production and installation of ventilation pipes and ducts shall comply with the current national design standards and the provisions of relevant products, and shall have the factory inspection certificate. When entering the site, the materials shall be accepted according to the current national standards.
