镀锌螺旋风管它是螺旋风管的一种，目前已经受到了广泛的使用，在化纤、石油化工、机械制造、医疗、食品等行业，都能看到它的身影。并且，它能用于多种场合，因此是一种不错的螺旋分管，那么下面烟台镀锌螺旋风管厂家我们来简单介绍一下这种风管，让大家能够对它有基础的了解。
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.
镀锌螺旋风管的两端，正常情况下是外接配件，比如弯头等，并且在两端还设有密封圈，但没有凹槽，其主要特点有：
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)外形美观、强度高、密封性能好。
(1) Beautiful appearance, high strength and good sealing performance.
(2)安装简单，使用寿命长。
(2) Simple installation and long service life.

(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、吊架间距，长为5米和3.75米，大不能超过这个范围。
(2) The distance between the supports and hangers is 5 meters and 3.75 meters, which cannot exceed this range.
(3)镀锌螺旋风管如是垂直安装，那么其间距不能大于4米。
(3) If the galvanized spiral air duct is installed vertically, its spacing shall not be greater than 4m.
(4)风管的支、吊架，好不要设在风口、阀门、检查门等这些位置上。
(4) The support and hanger of air duct shall not be set at the air outlet, valve, inspection door, etc.
(5)如果风管长度超过了20米，那么应设置防止风管摆动的固定点，且数量不能少于规定要求。
(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，应采用机械加工。且在安装好以后，不会有变形。
(6) The screw hole of the hanger shall be machined. After installation, there will be no deformation.
