大口径抽沙管道的优点：

The advantages of large diameter sand drainage pipe:

1、耐磨性：耐磨性是钢管的4-8倍，使用寿命更长；管道材质抗紫外线，抗老化。

1, wear resistance: wear resistance is 4-8 times of steel pipe, longer service life; pipe material resistance to ultraviolet, anti aging.

2、抗冲击：减缓对船体反冲击力，具有良好的弹性。

2, resistance to impact: to slow down the ship's anti - impact force, with good elasticity.

3、韧性好：耐疲劳、抗曲挠。良好的弯曲性，抗风浪，体现良好的灵活特性。

3, good toughness: fatigue resistance, anti bending. Good flexibly, resistance to wind and waves, showing good flexibility.

4、耐候性：良好的耐候性，不易氧化，爆裂。

4, weatherability: good weatherability, not easy to oxidize, burst.

5、安装使用方便：长为8-12米，或根据客户要求订做；每条管两头带活动金属法兰，管与管之间直接用螺栓连接。

5, easy to install and use: the length is 8-12 meters, or is customized according to the customer's requirements; each pipe has two moving metal flanges, and the pipe and pipe are directly connected with the bolt.
