为了减少粉尘和防止仪表、调压阀的指挥机构等因为堵塞失灵，常采用如下措施：In order to reduce dust and prevent the instrument, pressure regulating valve command organization because of blockage failure, often use the following measures：（）

A、脱除天然气中的水蒸气、氧、硫化物、二氧化碳等组分，减少管内腐蚀Remove water vapor, oxygen, sulfide, carbon dioxide and other components from natural gas, and reduce corrosion inside tube；
B、采用管内壁防腐涂尘，保护管材The inner wall of the pipe is used for anti-corrosion and dust coating to protect the pipe material；
C、定期清管和扫线Regularly pigging and sweeping；
D、在允许的情况下，采用所能达到的最低流速输气，减少气流冲击腐蚀和携尘能力To minimize shock corrosion and dust carrying capacity, the lowest possible flow velocity is used when permitted；
E、在集气站、配气站、调压计量站等处安设分离器、除尘器和过滤器，脱除各类固（液）体杂质Separators, precipitators and filters are installed in gas collecting stations, gas distribution stations and pressure regulating and measuring stations to remove all kinds of solid (liquid) body impurities。
