1. Product Characteristics
In the pipeline of petroleum, chemical, pharmaceutical, food and other industrial production devices, the mirror can observe the flow of liquid, gas, vapor, lubricant and other media in the pipeline at any time. It plays a role in monitoring production and avoiding accidents in the production process. It is an indispensable accessory to the pipeline device.
