Applications

Flange Spreading Wedges are designed to open flange joints with a minimum access gap of 5 mm.

The jaws of the tool open in a parallel motion which maintains a safe along with full step contact between the tool and the flange.

The parallel Jaw motion also ensures that the spreading forces are perpendicular to the flange face.

It is highly recommended that two or more Flange Spreading Wedges are used together to maintain a parallel Flange joint gap during spreading.

Operation

Ergonomic Guidelines

Consider this list of general ergonomic guidelines to identify areas for improvement in posture, handling or work environment.

  • Take frequent breaks and change work positions frequently.

  • Adapt the workstation area to your needs and the work task.

    • Adjust for a convenient reach range by determining where tools need to be located to avoid static load.

  • Avoid work positions above shoulder level or with static holding during assembly operations.

    • When working above shoulder level, reduce the load on the static muscles by lowering the weight of the tool, using for example torque arms, hose reels or weight balancers. You can also reduce the load on the static muscles by holding the tool close to the body.

    • Take frequent breaks.

    • Avoid extreme arm or wrist postures, particularly during operations requiring a degree of force.

  • Adjust for a convenient field of vision that requires minimal eye and head movements.

  • Use appropriate lighting for the work task.

  • Select the appropriate tool for the work task.

  • In noisy environments, use ear protection equipment.

Operating Instructions

Operating the Pump

  1. Connect the gauges to the pump.

    Make sure the control valves are closed.

  2. Remove the caps from the connectors.

  3. Connect the hose to the pump and to the tool.

  4. Close the pressure relief valve.

  5. Open the control valves simultaneously to apply the pressure on the connect tools.

  6. Use the handle to build the pressure in the pump.

    The safe working pressure must be 10,000 psi (700 Bar).

  7. Close one control valve, to increase the pressure on one active tool.

Depressurizing the Pump

  1. Open both control valves slowly.

  2. Open the pressure relief valve to depressurize the system.

  3. Check the gauges and make sure the pump is depressurized before disconnecting the coupling.

Operating the Flange Spreader

WARNING

Reduce Lateral Flange Movement

  • Before attaching the tool, make sure that at least two flange bolts remain in place 180 degrees apart with nuts loosened sufficiently enough for flange work to be carried out. These bolts will reduce the lateral flange movement during flange spreading.

  1. Before operating the tool for flange joint, check the minimum access gap should be 5 mm.

  2. Insert the first flange spreader into the flange Joint access gap.

  3. Insert the second flange spreader into the flange joint access gap.

  4. Make sure the tool is fully inserted.

  5. Operate the pump handle to pressurize the system. Refer to Operating the Pump.

  6. Once the required gap is formed into the flange joint, insert the safety block.

  7. Insert the safety blocks on both sides of the flange joint.

  8. Release the pressure and depressurize the system. Refer to Operating the Pump.

  9. The operator may perform the flange work now.

  10. Close the flange joint after the work is finished.

    Depressurize the system after the work is finished.

Service

Maintenance Instructions

Attaching the Stepped Block and Larger Safety Block

  1. A stepped block can be attached to the tool to increase the spreading distance.

  2. Use the retaining screw and hex key provided to attach the stepped block (1).

  3. A second stepped block can be attached to increase the spreading distance to a maximum of 124 mm (4.88 ”).

  4. When the tool is used with stepped blocks the large safety block must be used.

  5. Unscrew and remove the top block from the small safety block.

    Attach the top block on to the large safety block (2) and tighten the screw.

Maintenance Instructions

Service Recommendations

Preventive maintenance is recommended at regular intervals. See the detailed information on preventive maintenance. If the product is not working properly, take it out of service and inspect it.

If no detailed information about preventive maintenance is included, follow these general guidelines:

  • Clean appropriate parts accurately

  • Replace any defective or worn parts

Maintenance

  • Visually Inspect the tool, jaws, wedge and coupler for any damage.

  • Replace the worn or damaged parts

  • Clean and remove the access grease from the surfaces and coupler

  • Clean the coupler and put the protective cover.

  • Apply the grease to the tool jaws (1) with a high load bearing grease.
