Galvanized spiral air duct is a kind of spiral air duct, which has been widely used in chemical fiber, petrochemical, machinery manufacturing, medical, food and other industries. In addition, it can be used in many occasions, so it is a good spiral branch pipe. Now let's briefly introduce the Yantai galvanized spiral air duct manufacturer, so that you can have a basic understanding of it.

鍍鋅螺旋風管的兩端，正常情況下是外接配件，比如彎頭等，并且在兩端還設有密封圈，但沒有凹槽，其主要特點有：

Both ends of the galvanized spiral air duct are normally external fittings, such as elbows, and there are sealing rings at both ends, but no grooves. Its main features are:

(1)外形美觀、強度高、密封性能好。

(1) Beautiful appearance, high strength and good sealing performance.

(2)安裝簡單，使用壽命長。

(2) Simple installation and long service life.

(3)內外壁都非常光滑，因此風道阻力小，使用時不會產生噪音。

(3) The inner and outer walls are very smooth, so the resistance of the air duct is small, and no noise will be generated during use.

(4)基本上不需要進行維護，還能降低能耗，節約費用。

(4) Basically, maintenance is not required, and energy consumption and cost can be reduced.

鍍鋅螺旋風管的安裝規定也是很重要的，其主要內容有：

The installation regulations of galvanized spiral air duct are also very important, which mainly include:

(1)鍍鋅螺旋風管如是水平安裝，如果直徑或長邊尺寸不大于400毫米，那么其間距不能大于4米；如果直徑或長邊尺寸大于400毫米，那么其間距不能大于3米。

(1) If the galvanized spiral air duct is installed horizontally, if the diameter or long side size is not more than 400mm, the spacing shall not be more than 4m; If the diameter or long side size is greater than 400mm, the spacing shall not be greater than 3m.

(2)其支、吊架間距，長為5米和3.75米，大不能超過這個范圍。

(2) The distance between the supports and hangers is 5 meters and 3.75 meters, which cannot exceed this range.

(3)鍍鋅螺旋風管如是垂直安裝，那么其間距不能大于4米。

(3) If the galvanized spiral air duct is installed vertically, its spacing shall not be greater than 4m.

(4)風管的支、吊架，好不要設在風口、閥門、檢查門等這些位置上。

(4) The support and hanger of air duct shall not be set at the air outlet, valve, inspection door, etc.

(5)如果風管長度超過了20米，那么應設置防止風管擺動的固定點，且數量不能少于規定要求。

(5) If the length of the air duct exceeds 20 meters, fixed points shall be set to prevent the air duct from swinging, and the number shall not be less than the specified requirements.

(6)吊架的螺孔，應采用機械加工。且在安裝好以后，不會有變形。

(6) The screw hole of the hanger shall be machined. After installation, there will be no deformation.
