Product Overview
Our fixed spray nozzle is a dedicated stationary jet component engineered for coiled tubing workover, wellbore cleaning, acid jetting and scale removal tasks. Manufactured from high-strength alloy steel via precision CNC machining, it comes with integrated external thread for direct mounting on jetting tools, wash pipes and bottom hole assemblies. The fixed internal flow channel delivers consistent, focused spray patterns without rotational components, eliminating mechanical failure risks caused by moving parts. Hardened flow passage greatly reduces abrasive wear from sand-laden fluid, extending service life during prolonged washing operations. The streamlined outer profile lowers flow resistance while tripping inside casing; customizable orifice diameter and thread specifications allow seamless integration with various downhole tool setups.
