Three Distinct Functions

  • Recirculation (bypass) flow control for pump protection
  • Pre-fill of decoking lines, hoses, manifolds, etc., at a predetermined flow rate to prevent water hammer
  • Full flow to the decoking tool nozzles. Very low pressure drop (high Kv [Cv]) in full flow for reduced energy consumption

Features and Benefits

  • Cost-effective solution
  • Design and maintenance simplicity with minimal moving parts
  • No foundation required

Design Features

  • Long Stroke, Single Stem Operation
    • Assures no unwanted overlap of functions
  • Non-Clogging Design
    • Passes particles up to 3 mm (1/8 in)
  • Compact Design
    • Simplifies installation. Suitable for direct mounting on the jet pump
  • Stainless Steel
    • Inlaid at all gasket surfaces, option for fully lined body
  • Valve Stem Sealing
    • Using low friction elastomer rings. No adjustment…no packing required
  • Proven, Replaceable, Durable Soft Seals
    • Assures zero leakage with water and coke fines – no lapping required during repairs
  • Instant Return
    • To any operating mode upon command
  • Actuation
    • Limitorque® motor operator is standard. Optional double-acting pneumatic actuator with positioner is available with 5.5 bar (80 psi) to 7 bar (100 psi) air supply requirement
  • Decoking Valve Upgrade Options
    • A Flowserve decoking expert can help specify appropriate materials and design enhancements, controls and instrumentation for specific service requirements

Hydraulic Decoking System Rotary Joint

Control System

说明: 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.

Hydraulic Decoking Systems AutoShift™ Cutting Tool

说明: 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.

Hydraulic Decoking Systems Rotary Joint

说明: 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.

Hydraulic Decoking Systems Drill Stem Guide and Shroud Assembly

说明: 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.

Hydraulic Decoking Systems Latching Mechanisms

说明: 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.

Hydraulic Decoking Systems Video Monitoring System

说明: Video monitoring systems provide critical feedback to operators and are an essential part of remotely operated coke cutting systems from Flowserve.

Hydraulic Decoking Systems Audio Monitoring System

说明: Audio monitoring systems provide critical feedback to operators and are an essential part of remotely operated coke cutting systems from Flowserve.

Pulley Blocks and Sheaves

说明: 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.

Hydraulic Decoking Systems Jet Pump

说明: 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.

Hydraulic Decoking Systems Crosshead (Free Fall Arrestor)

说明: 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.

Decoking Winch

说明: 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.

Hydraulic Decoking Systems Coke Drum Monitoring

说明: 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.

Hydraulic Decoking Systems Drill Stem

说明: Flowserve threaded drill stems are extremely durable for decoking service with a side load strength four times greater than comparable welded drill stem designs.

除焦软管

说明: 除焦软管将水从工作台连接输送到旋转接头。 这种高压软管可处理 5000 psi 以及高达 450° F 的温度。

Isolation and Bleed Valves

说明: 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.

Hydraulic Decoking Systems Tensiometer / Load Cell

说明: 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.
