    镀锌铁皮风管材料的厚度怎么决定?

    来源:http://www.luyunhuanbao.com/     发布时间:2023-01-17  

    由风管的长边(圆风管是直径)尺寸,及风管工作压力共同决定:
    It is determined by the size of the long side of the air duct (the diameter of the round air duct) and the working pressure of the air duct:
    低压系统:P≤
    Low-voltage system: P ≤
    中压系统:
    Medium voltage system:
    高压系统:
    High pressure system:
    以中低压、镀锌铁皮风管板厚为例:
    Take the thickness of medium and low pressure galvanized iron sheet air duct as an example:
    风管长边尺寸b≤320mm:

    Air duct long side dimension b ≤ 320mm:
    风管长边尺寸b≤630mm:
    Air duct long side dimension b ≤ 630mm:
    风管长边尺寸b≤1000mm:
    Air duct long side dimension b ≤ 1000mm:
    风管长边尺寸b≤2000mm:
    Air duct long side dimension b ≤ 2000mm:
    风管长边尺寸b≤4000mm:
    Air duct long side dimension b ≤ 4000mm:
    以上均出自《通风与空调工程施工质量验收规范GB50243-2002》
    The above are from Code for Acceptance of Construction Quality of Ventilation and Air Conditioning Engineering GB50243-2002
    其它材料如铝板、玻璃钢风管,详见以上规范表4.2.1-1到
    Other materials, such as aluminum plate and GRP air duct, are detailed in Table 4.2.1-1 to
