1.镀锌螺旋风管在安装需要检查风管是否合格,产品检查合格后再进行部分配件组装,组装后再进行风管清洁与高空安装。

1. galvanized spiral pipe in the installation needs to check whether the wind pipe is qualified, product inspection qualified after part of the assembly, after assembly of the wind pipe cleaning and high altitude installation.

2.镀锌螺旋风管在安装现场时需要进行水平安装时，螺旋风管的直径或长边尺寸不能小于或等于40cm，间距不应大于4m；如螺旋风管的直径或长边尺寸大于 40cm，那么它间距不应大于3m。同时镀锌螺旋风管的支、吊架间距可分别延长至5m 和3.75m；对于薄钢板法兰的镀锌螺旋风管，其支、吊架间距不应大于3m。

2. when installing the galvanized spiral pipe in the installation site, the diameter or length of the long side of the spiral pipe should not be less than or equal to 40cm, and the distance should not be greater than 4m; if the diameter of the spiral pipe or the size of the long side is larger than 40cm, it should not be more than 3m. At the same time, the distance between the support and the hanger of the galvanized spiral pipe can be extended to 5M and 3.75m respectively. For the galvanized spiral pipe of the thin plate flange, the distance between the support and the hanger should not be greater than that of 3M.

3、镀锌螺旋风管需要进行垂直安装时，风管间距不应大于4m，单根直管必须至少应有2 个固定位定住。

3. When the galvanized spiral pipe needs vertical installation, the distance between the air pipes should not be greater than 4m, and the single straight pipe must have at least 2 fixed positions.

4、镀锌螺旋风管支、吊架需按国标标准选用强度和刚度相适应的规格和样式。对于直径或边长大于250cm 的超宽、超重等特殊镀锌螺旋风管的支、吊架应按特殊设计规定。

4. Galvanized spiral pipe supports and hangers should be selected according to the national standard standards and styles that are suitable for strength and rigidity. For the special zinc coated spiral pipes with diameter or side length larger than 250cm, the support and hangers should be specified according to the special design requirements.
