8.在制作镀锌风管时，应尽可能地减少垂直直缝和不水平接缝。圆周小于或等于900 mm的底板不得有接缝，超过900 mm无横向接缝。
8. When making galvanized air duct, vertical straight joints and non horizontal joints shall be reduced as much as possible. Baseplates with a circumference less than or equal to 900 mm shall not have joints, and those with a circumference greater than 900 mm shall not have transverse joints.
9.在板料大小符合切割要求且损失不大的情况下，可将弯头、三通等附件与直线段进行联接，以减小通风管道阻力。
9. When the size of the sheet meets the cutting requirements and the loss is small, the elbow, tee and other accessories can be connected with the straight section to reduce the resistance of the ventilation pipe.
本产品主要应用于工业及工程建筑，适用于工业、各种空调及通风系统的施工，适用于食品、机械、医药、电子、、体育娱乐、酒店、酒店、、办公楼、、别墅、航天航空制造等行业。特别是消防通风管道工程及民用建筑的通风、通风工程及工业。
This product is mainly used in industrial and engineering buildings, applicable to the construction of industrial and various air conditioning and ventilation systems, and applicable to food, machinery, medicine, electronics, shopping malls, sports and entertainment, hotels, hotels, shopping malls, office buildings, government agencies, villas, aerospace manufacturing and other industries. In particular, fire ventilation pipeline engineering and civil building ventilation, ventilation engineering and industry.
在各种通风条件下，镀锌风管具有的韧性和不脆性，是其优点之一。由于长时间的风吹雨打，一些数据会变得老化、腐烂、侵蚀。镀锌板风管的镀锌保护管道铁板不被氧化。
Under various ventilation conditions, galvanized air duct has excellent toughness and non brittleness, which is one of its advantages. Due to long-term wind and rain, some data will become aged, rotten and eroded. Galvanizing of galvanized sheet air duct protects the iron sheet of the pipe from oxidation.
镀锌管道内壁润滑，阻力小，通风损失小，能耗低，经济运行费用高，密封性好，抗压强度高。另外，在实际工程中，使用镀锌管道的一个普遍原因是其耐火性能良好。镀锌管线结构简单，施工方便，与土建工程密切结合，特别适合于各种复杂的净化及通风工程。该产品广泛应用于，办公楼，地铁入口，大型，现代工厂消防排烟，空调通风，除尘等。
The inner wall of galvanized pipe is lubricated, with small resistance, small ventilation loss, low energy consumption, high economic operation cost, good sealing and high compressive strength. In addition, in practical projects, a common reason for the use of galvanized pipes is their good fire resistance. Galvanized pipeline is simple in structure and convenient in construction. It is closely combined with civil engineering, especially suitable for various complex purification and ventilation projects. This product is widely used in shopping malls, office buildings, subway entrances, large shopping malls, modern factories, fire control smoke exhaust, air conditioning ventilation, dust removal, etc.
The above is a detailed introduction to the ventilation pipes in Jinan. I hope it will be helpful to you. If you have any questions, please contact us. We will provide services for you with our attitude http://www.jntfgd.com
