PP air duct features:

1.不锈蚀：可在很***的温度范围内承受PH值，范围在1～14的高浓度的酸和碱的腐蚀。

1. No corrosion: it can withstand the corrosion of high concentration acid and alkali with pH value in a wide range of temperature, ranging from 1 to 14.

2.耐磨损、不结垢：pp风管及管件内壁均匀光滑，流动阻力小并且不结垢。

2. Wear resistance and no scaling: the inner wall of PP air duct and pipe fittings is even and smooth, with small flow resistance and no scaling.

3.减小振动和噪声：具有******的隔声性能，可显著减少由液体流动引起的振动和噪声。

3. Reduce vibration and noise: with excellent sound insulation performance, it can significantly reduce the vibration and noise caused by liquid flow.

4.防冻裂：PP材料弹性******使得管材和管件截面可随着冻胀的液体一起膨胀而不会胀裂。

4. Anti freezing crack: PP material has excellent elasticity, so that the cross section of pipe and pipe fittings can expand with the frost heaving liquid without cracking.

5.防结露，热损失少：PP材料为不***热导体，可减少结露现象并减少热损少。

5. Anti condensation and less heat loss: PP material is a poor heat conductor, which can reduce condensation and heat loss.

6.安装简单：重量轻，安装操作方便，并且具有可焊性。

6. Simple installation: light weight, convenient installation and operation, and weldability.

7.使用寿命长：pp风管系统在规定的使用条件下寿命达50年。

7. Long service life: PP air duct system has a service life of 50 years under specified service conditions.

pp风管安装步骤：

PP duct installation steps:

1、安装pp风管时，应考虑环境温度对安装质量的影响，一般气温高于40℃或低于0℃时，不宜施工安装。

1. When installing PP air duct, the impact of ambient temperature on installation quality shall be considered. Generally, when the temperature is higher than 40 ℃ or lower than 0 ℃, it is not suitable for construction and installation.

2、由于pp风管线膨胀系数较***，故在安装时要考虑热补偿，一般以自然补偿为主，如采用方形伸缩器。

2. Due to the large expansion coefficient of PP air pipeline, thermal compensation shall be considered during installation, which is generally based on natural compensation, such as square expansion device.

3、在架空敷设时，应对管道采用管托支承，管托可用角钢、对剖的钢管等材料，使增强聚丙烯在管托上可以自由伸缩。

3. When laying overhead, the pipe shall be supported by pipe support, which can be made of angle steel, split steel pipe and other materials, so that the reinforced polypropylene can freely expand and contract on the pipe support.

4、pp风管需要暗设时。建议采用管沟敷设，管子一般采用焊接连接型式，若因***殊原因需要埋地时，应采用套管形式直埋，以避免回填土内混有硬杂物，报坏管子。

4. When PP air duct needs to be concealed. It is recommended to use pipe trench laying, and the pipe is generally welded connection type. If it needs to be buried due to special reasons, it shall be directly buried in the form of casing to avoid hard sundries mixed in the backfill and damage of the pipe.

5、pp风管采用法兰连接时，应严格对中，轴向***允许偏差不***于2mm，不得采用强制拧紧螺栓的方法来调整，拧紧螺栓分两次进行，***次按对角线均匀对称地拧一遍，然再拧紧螺栓。

5. When PP air duct is connected by flange, it shall be strictly aligned, and the maximum allowable axial deviation shall not be greater than 2mm. It is not allowed to use the method of forced tightening of bolts for adjustment. The tightening of bolts shall be carried out in two times, the first time shall be uniformly and symmetrically screwed once according to the diagonal, and then the bolts shall be tightened.
