白铁皮通风管道加工工艺要求：

Process requirements for processing white iron ventilation pipes:

应采用咬口连接或铆接，不得焊接。白铁皮通风管道板材拼接的咬口缝应错开，不得有十字型拼接缝。咬口缝紧密、宽度一致，折角平直，圆弧均匀且两端面平行。核实风管系统的标高，轴线、预留孔洞，预埋件等是否符合安装条件。备足安装用的各类辅助材料，准备好吊装机具和安装用的其它工具，对风管系统划线定位等工作。

It should be connected by biting or riveting, and welding is not allowed. The bite seams of the splicing of white iron sheet ventilation duct boards should be staggered and there should be no cross shaped seams. The bite seam is tight, the width is consistent, the folding angle is straight, the arc is even, and the two end faces are parallel. Verify whether the elevation, axis, reserved holes, and embedded parts of the air duct system meet the installation conditions. Prepare various auxiliary materials for installation, prepare lifting equipment and other tools for installation, and mark and position the air duct system.

Technical requirements for the processing of Jinan iron sheet air ducts:

角钢规格可以略小于法兰规格，当大边尺寸为630-800mm时，可采用∠25*4的扁钢做加固框；当大边尺寸为800-1250mm时可采用∠25*25*4的扁钢做加固框。

The size of the angle steel can be slightly smaller than the flange size. When the large edge size is 630-800mm, a ∠ 25 * 4 flat steel can be used as the reinforcement frame; When the size of the large edge is 800-1250mm, a ∠ 25 * 25 * 4 flat steel can be used as a reinforcement frame.

风管板材采用咬口连接时，咬口的形式有单咬口、联合角咬口、转角咬口、按扣式咬口和立咬口。其中单咬口、联合角咬口、转角咬口适用于微压、低压、中压及高压系统。在较大规模的风管制作项目中，卷板可以提高工效。但是卷板必须经过校正,否则会因为钢板本身的变形而影响风管加工的外观质量。

When the air duct board is connected by bite, the forms of bite include single bite, combined corner bite, corner bite, snap fit bite, and vertical bite. Single bite, combined corner bite, and corner bite are suitable for micro pressure, low pressure, medium pressure, and high pressure systems. In large-scale air duct production projects, rolling plates can improve work efficiency. However, the rolling plate must be calibrated, otherwise it will affect the appearance quality of the air duct processing due to the deformation of the steel plate itself.

白铁皮通风管道的板材加工厚度应符合产品标准，产品标准中板材公称厚度是允许有偏差，不同精度要求、宽度不同、屈服强度不同，允许偏差是不一样的。立管支架不足。GB50243规定，垂直安装时，支架间距不应大于4m。班组一般都是每层做一个支架，对于商业项目，层高往往超过4m，这就需要每层中间还需要加一个支架。

The processing thickness of the sheet metal ventilation pipeline should comply with the product standard. The nominal thickness of the sheet metal in the product standard allows for deviation, and the allowable deviation varies depending on the accuracy requirements, width, and yield strength. Insufficient stand pipe support. GB50243 stipulates that when installed vertically, the spacing between supports should not exceed 4m. Teams usually make a bracket for each floor. For commercial projects, the height of the floor often exceeds 4m, which requires an additional bracket in the middle of each floor.
