镀锌钢板风管可按截面形状和材质分类。按截面形状,镀锌风管可分为圆形风管,矩形风管,扁圆风管等多种,其中圆形风管阻力小的高度尺寸大,制作复杂。所以应用以矩形风管为主。
Galvanized steel duct can be classified according to cross-sectional shape and material. According to the cross-sectional shape, galvanized air ducts can be divided into various types, such as circular air ducts, rectangular air ducts, flat circular air ducts, etc. Among them, circular air ducts have small resistance, large height dimensions, and complex manufacturing. So the application is mainly based on rectangular air ducts.
镀锌钢板风管广泛应用于民用及工业领域，比如：高层建筑的地下车库、宾馆、酒店、、医院、写字楼、车间厂房、纺织、石油化工、机械制造、仪表、电子、医药、烟草、食品以及地铁、人防等工程的送风、排风、排烟管道。镀锌风管通常在连接的时候，两端总是外接于配件（如弯头、变径）。
Galvanized steel sheet air ducts are widely used in civil and industrial fields, such as underground garages, hotels, hotels, shopping malls, hospitals, office buildings, workshops, textile, petrochemical, mechanical manufacturing, instruments, electronics, medicine, tobacco, food, as well as air supply, exhaust, and smoke exhaust pipes for subway, civil air defense, and other engineering projects in high-rise buildings. Galvanized air ducts are usually connected externally to fittings (such as elbows, reducers) at both ends.
镀锌钢板风管成品如何保护？风管加工设备上应覆盖柔性材料，且不得影响设备操作；进入车间应更换布鞋，禁止在镀锌钢板上踩踏；风管合缝及敲翻边时使用橡胶锤配合液压合缝机，不得使用金属锤；
How to protect finished galvanized steel duct products? The air duct processing equipment should be covered with flexible materials and should not affect equipment operation; Cloth shoes should be replaced when entering the workshop, and stepping on galvanized steel plates is prohibited; When sealing and flipping the air duct, use a rubber hammer in conjunction with a hydraulic sealing machine, and do not use a metal hammer;
风管下料、合缝、装配法兰等工序须在柔性地毯上操作，严禁风管镀锌层与地面直接接触；风管半成品、成品须整齐放置在方木上，每层不超过1.2m，严禁多层堆放造成风管变形；
The cutting, jointing, and flange assembly processes of the air duct must be carried out on flexible carpets, and direct contact between the galvanized layer of the air duct and the ground is strictly prohibited; The semi-finished and finished products of the air duct must be neatly placed on square timber, with each layer not exceeding 1.2m. It is strictly prohibited to stack multiple layers to cause deformation of the air duct;
山东通风管道加工表示风管成品长时间堆放时应用塑料薄膜覆盖，避免积灰；镀锌钢板应放在宽敞干燥的隔潮木头垫架上，码放时按系统编号，整齐、合理，便于装运。搬运装卸应轻拿轻放，防止损坏成品。
Shandong ventilation pipeline processing indicates that when finished air ducts are stacked for a long time, they should be covered with plastic film to avoid dust accumulation; Galvanized steel plates should be placed on spacious and dry damp proof wooden pallets, neatly and reasonably numbered according to the system during stacking, for easy shipping. Handling and loading should be handled with care to prevent damage to the finished product.
