The screw-on swivel is a core integrated equipment with dual functions of "fluid circulation + drilling tool screw-on" in petroleum drilling and workover operations. It is a key equipment for making single joints, unscrewing the kelly, and conventional drilling operations. Its innovation integrates the swivel and kelly screw-on device into one, without the need for additional connecting parts. The XSL series screw-on swivels cover models such as XSL225, XSL450, and XSL675, suitable for medium-deep well and deep well operation scenarios.
- The lower end joint thread adopts API standard REG specification, which can precisely match various kellys.
- The washpipe packing assembly adopts a quick-release box structure, and the seal can be replaced without disassembling the hose and gooseneck, making operation convenient.
Core load-bearing parts are made of high-quality alloy steel to eliminate safety hazards such as shell cracking and center tube deformation.
