石油管线是由油管及其附件所组成，并按照工艺流程的需要，配备相应的油泵机组，设计安装成一个完整的管道系统，用于完成油料接卸及输转任务。输油管道主要包括等温输送、加热输送和顺序输送。管道的腐蚀及其预防是管道维护的重要环节之一。
气动球阀(英文名:Electronic Ball Valve)由气动执行机构和气动球阀组成。它是一种用于工业自动化过程控制的管道压力元件，通常用于管道介质的远程开/关控制。气动球阀标准GB/T21465-2008《阀门术语》定义为启闭件(球)由阀杆驱动，绕阀杆轴线旋转的阀门。主要用于切断或接通管道中的介质，也可用于调节和控制流体。其中，硬密封V形气动球阀的V形球芯与硬面硬质合金金属阀座之间具有很强的剪切力，特别适用于含有纤维、微小固体颗粒等介质。
气动球阀结构简单，仅由几个零件组成，节省数据消耗；体积小，重量轻，安装尺寸小，驱动扭矩小，调压阀，操作简单敏捷，只需旋转90°即可快速启闭；同时具有良好的流量调节效果和密封特性。在大中口径、中低压的应用范畴中，电动球阀是占主导地位的阀门情况。电动球阀在全开时，蝶板的厚度是介质流经阀体的阻力，所以通过阀门的压降很小，因此具有良好的流量控制特性。电动球阀有两种类型:弹性密封和金属密封。
根据用户的需要，可设计成适用于含固体颗粒、料浆等介质的结构或耐较高温度的结构。球体的加工精度非常精密，操作轻便，无不良干涉。阀座采用PTFE+25％玻纤或PEEK。 PTFE+25％玻纤在高压下能获得比PTFE更好的性能，而且还能减少酸性介质腐蚀，通常在800磅级 的压力下采用；另外可以根据客户要求定做进口PEEK材质，以适应高温，高压工况下的高密封工 作性能。具有防阀杆吹出结构。
与同类行业的同种规格产品相比，占地空间少，而且外型美观。在保证阀门正常操作、使用情况下，使用寿命在15年以上。
气动球阀是所有阀类中流体阻力最小的一种，以压缩空气为动力，通过活塞齿条，齿轮的机械传动阀杆，以角行程输出的扭矩转动球体 0~90°，就能快速完成启闭动作或调节动作，操作方便快捷。球芯通道平整光滑，不易沉积介质，可以进行管线式通球。
