1. General Information
The DFT16 FF Two End Flanged Pipe is designed for use in distribution networks and pumping stations, requiring reliable and rigid connections. Proper installation is essential to guarantee safe operation, long service life, and efficient, leak-free performance within the pipeline system.
2. Safety Precautions
Installation must be performed by qualified personnel only.
Ensure strict compliance with all local safety regulations and standards concerning pipeline pressure and heavy equipment handling.
Personnel must wear appropriate personal protective equipment (PPE) at all times.
Confirm that the pipeline section is fully depressurized and drained before attempting to install the DFT16 FF Two End Flanged Pipe.
3. Pre-Installation Checklist
Inspect the DFT16 FF Two End Flanged Pipe for any visible damage to the flange faces or the protective coating sustained during transport or storage.
Check that the nominal size, pressure rating, and exact length match the system design requirements.
Verify that the interior and flange seating areas are clean and free from debris.
Confirm that the mating pipeline ends are correctly aligned, as this rigid spool piece cannot compensate for axial or angular misalignment. Ensure that high-quality gaskets and appropriate bolts are available for assembly.
4. Installation Procedure
For positioning, carefully lift and align the DFT16 FF Two End Flanged Pipe between the mating flanges of the pipeline.
Ensure the pipeline is clean and free from dirt, sand, or foreign particles. Use proper gaskets suitable for the medium and operating conditions.
Align the flange holes and insert all bolts. Tighten the bolts in a cross-pattern sequence in gradual steps to ensure even compression of the gasket.
Do not use excessive force that may damage the flange faces or bolts.
5. Post-Installation
Slowly pressurize the system and check for leaks around the connections. Personnel should carefully visually check both flange joints for any signs of weeping.
If leakage is detected, depressurize the system and re-tighten the bolts following the correct sequence.
Record the installation details for documentation.
Proper maintenance extends the service life of the DFT16 FF Two End Flanged Pipe and ensures reliable sealing integrity during testing and isolation periods. Follow the guidelines below to maximize the longevity of this essential unit.
1. Routine Operation
Visually inspect the DFT16 FF Two End Flanged Pipe area regularly, for example annually, for signs of external leakage, soil erosion around the joint, or movement of the pipe. If the fitting is used for long-term isolation, check the bolt tension periodically to ensure the mechanical seal remains secure.
The DFT16 FF Two End Flanged Pipe is a static component and requires no internal operation; ensure the surrounding environment remains clear for inspection.
2. Inspection Schedule
Monthly, check the visible bolts for signs of loosening or severe corrosion.
Quarterly, check the ground surface above the buried pipe for signs of heaving or settling, which may indicate axial thrust movement.
Annually, perform a detailed inspection including the gaskets, bolt condition, and coating integrity. Perform a torque verification check on all flange bolts to ensure the specified clamping force is maintained.
3. Lubrication
The DFT16 FF Two End Flanged Pipe is a mechanical sealing device and requires no lubrication after installation.
The rubber gaskets and flange faces should be kept clean during storage and installation to ensure proper seating.
4. Seal and Gasket Replacement
Replace flange gaskets and bolts if leakage or significant wear is observed. Always depressurize and drain the pipeline before performing any maintenance work.
Only use original spare parts to guarantee compatibility and reliability.
5. Cleaning
Keep the exterior of the flanged pipe clean to prevent corrosion.
In aggressive environments, consider applying additional protective coating or insulation.
6. Storage and Spare Parts
Store spare parts in a dry, clean environment, away from direct sunlight.
Maintain a record of all inspections, repairs, and replacements.
