输油管道的管材一般为钢管，使用焊接和法兰等连接装置连接成长距离管道，并

The pipeline is generally steel pipe, welding and flanges from the pipe connection means growth, and use of the valve opening and closing control and flow regulation. The main transport pipeline isothermal heat delivery order and delivery transport process and the like. Pipeline corrosion and how corrosion is an important part of pipeline maintenance. Currently oil pipeline has become one of the main transport tool, and still has considerable development potential in the future. <br>1, the interior of the pipeline company <br>2, a long distance pipeline <br>3, crude oil pipeline <br>4, refined oil pipeline

The pipe of the pipeline is generally a steel pipe, which is connected to the growth distance pipe using a connection such as welding and flange, and a valve is used for open and close control and flow adjustment. The pipeline mainly has the same temperature transport, heating transport and sequential transportation process. The corrosion of pipe and how to prevent corrosion are one of the important links of pipeline maintenance. At present, the pipeline has become one of the main transportation tools of oil, and in the future it still has considerable development potential.<br>1, the internal oil pipeline<br>2, long-distance pipeline<br>3, crude oil pipeline<br>4, oil pipeline

The pipe material of oil pipeline is generally steel pipe, which is connected with long distance pipeline by welding and flange, and the valve is used for opening and closing control and flow regulation. The oil pipeline mainly includes isothermal transportation, heating transportation and sequential transportation. Pipeline corrosion and how to prevent corrosion is one of the important links of pipeline maintenance.
