The gas cylinder tube is an accessory that connects to the outside world. In the case of pumping gas cylinders, metal hoses must be used due to the high working pressure. The gas in the bottle should be used in the customer's production process. Due to the application of gas pressure reducing valves, plastic and plastic hoses made of rubber and plastic products are generally used, but large and medium-sized mining enterprises use more metal hoses. The consumption is large, and the work pressure is also higher than that of small and medium-sized manufacturing enterprises.
