The small and medium swivel is suspended below the hook, connecting the hose and the kelly, simultaneously realizing the three core functions of suspending the load, rotating the drill string, and circulating drilling fluid. It strictly follows international standards such as API Spec 8C, covering the full range of SL45--SL90 specifications, and has become the preferred equipment for medium and small oil and gas fields, geothermal development, and conventional workover operations.
- It adopts a box-type integral washpipe packing assembly, which is convenient and efficient to operate;
- The shell adopts a sealed oil reservoir design, effectively preventing sand, mud, and drilling fluid from invading the inside of the bearing. It can achieve long-term continuous operation without frequent maintenance, greatly reducing the risk of operation interruption.
- Key parts have undergone 100% magnetic particle and ultrasonic non-destructive testing to avoid quality defects from the source.
