Hydraulic Decoking Systems AutoShift™ Cutting Tool
The AutoShift combination decoking tool makes remote drum decoking feasible by removing the operator from the cutting deck. Boring and cutting mode shifting is accomplished automatically and safely within the drum by water pressurization and depressurization.

Features and Benefits
The AutoShift combination decoking tool provides numerous benefits to hydraulic decoking operations:
- Improved Operator Safety – Remote operation eliminates operator exposure to high-pressure water, steam eruptions, H2S vapors and mechanical hazards
- Greater System Automation – Automatic shifting coupled with computerized controls and instrumentation enables total process automation
- Reduced Cycle Times – Automatic shifting within the drum saves 30 minutes or more per cycle
- Improved Efficiency – The decoked vessel returns to service more quickly and safely
- Easier Maintenance – AutoShift features a self-cleaning design that flushes coke fines from the shifting mechanism and jet ports
- Shifting Flexibility – “Stuck” tools can be freed up quickly within the drum by automatically shifting between boring and cutting modes
- Manual Shift Feature – If necessary, AutoShift can quickly and easily shift modes as with traditional combination cutting tools
- Retrofit Cartridge Assembly – Existing Flowserve (i.e., Worthington, Pacific) and non-Flowserve hydraulic decoking systems can upgrade to AutoShift technology

|Description:||The decoking winch is specifically designed for use in coke cutting to raise and lower the cutting tool in the coke drums. Several unique features are incorporated to assure safe, reliable operation in the most demanding environments.|
|Description:||Flowserve decoking hoses are designed for the harsh environment of the delayed coker. These high-pressure hoses are oil and chemical resistant and feature abrasive-resistant outer covers with multiple layers of wire reinforcement for strength and durability.|
|Description:||Video monitoring systems provide critical feedback to operators and are an essential part of remotely operated coke cutting systems from Flowserve.|
|Description:||The Flowserve Pacific® heavy-duty rotary joint is robustly designed to support the suspended loads experienced in coking units. Its function is to transmit cutting fluid from the stationary hose connection to the drill stem and cutting tool. Flowserve is continually upgrading its rotary joint to accommodate increasingly higher cutting pressure requirements.|
|Description:||The crosshead and free fall arrestor unit guides and centers the rotary joint-drill stem-cutting tool assembly in the coke drum. The crosshead is designed to safely absorb all torque loads normally sustained from cutting operations.|
|Description:||The Flowserve decoking control valve controls the flow from the jet pump with a single valve providing three distinct features: recirculation flow control, pre-fill and full flow to the decoking tool nozzles.|
|Description:||The lifting mechanism for the drill string utilizes multiple blocks and sheaves built to Flowserve specifications. Multiple sizes and load ratings are available to meet specific unit requirements.|
|Description:||Audio monitoring systems provide critical feedback to operators and are an essential part of remotely operated coke cutting systems from Flowserve.|
|Description:||Flowserve latch mechanisms enable stowing of the crosshead when not in use, providing a safe and practical way to remove tension on the cable and winch.|
|Description:||The Flowserve compression type tensiometer replaces typical designs used for measuring cable tension. The result is a more practical load measurement system with many safety, operation and maintenance advantages.|
|Description:||Built to meet or exceed ISO 13709/API 610 (BB5), latest design, the WIK is a multistage, double-case barrel pump. Its unique low specific speed hydraulics and extra heavy-duty design are especially engineered for reliable service in jet pump decoking services. The WIK is intended for special purpose, unspared, high-power density and extremely arduous conditions.|
|Description:||The Flowserve drill stem guide and shroud can accommodate up to 305 mm (12 inches) of overall lateral misalignment. The innovative design rides on the drill stem and fully encloses the cutting tool. It diverts dangerous water flow vertically away from operators in the unlikely event a pressurized cutting tool is retracted from the drum or energized while stowed.|
|Description:||Flowserve coke drum monitoring systems provide coke cutting personnel with positive confirmation that the coke has been removed and the cutting process can continue. The system can be integrated with the decoking control system for maximum ease-of-use or provided as a stand-alone option.|
|Description:||Customized decoking ball valves are used to manage cutting water flow to the coke drums and to relieve drum pressure. The valve designs incorporate unique features that provide long life and safe operations.|
|Description:||The decoking operating system utilizes state-of the-art programmable controllers, monitoring equipment, and field devices with over 20 years of field-proven design techniques.|
|Description:||Flowserve threaded drill stems are extremely durable for decoking service with a side load strength four times greater than comparable welded drill stem designs.|
