1. General Information
The DFT17 Q Elbow Piece is designed for use in distribution networks and pumping stations, requiring reliable directional changes between flanged and socketed components. 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 during the process.
Confirm that the pipeline section is fully depressurized and drained before attempting to install the DFT17 Q Elbow Piece.
3. Pre-Installation Checklist
Inspect the DFT17 Q Elbow Piece for any visible damage to the flange faces, spigot end, or the protective coating sustained during transport or storage.
Check that the nominal size, pressure rating, and angle match the system design requirements.
Verify that the interior and sealing areas are clean and free from debris.
Confirm that the mating pipeline ends are correctly aligned, as improper positioning can cause mechanical stress. Ensure that high-quality gaskets and appropriate bolts are available for assembly.
4. Installation Procedure
For positioning, carefully maneuver the DFT17 Q Elbow Piece into the correct orientation within the pipeline layout.
Ensure the pipeline interior is clean and free from dirt, sand, or foreign particles. Use proper gaskets and seals suitable for the medium and operating conditions.
Insert the spigot end or align the flange holes and insert all bolts as required. 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 body or connections.
5. Post-Installation
Slowly pressurize the system and check for leaks around the connections. Personnel should carefully visually check all 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 purposes.
Proper maintenance extends the service life of the DFT17 Q Elbow 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 DFT17 Q Elbow Piece area regularly, for example annually, for signs of external leakage, soil erosion around the joint, or movement of the pipe. Check the connection tension periodically to ensure the mechanical seal remains secure.
The DFT17 Q Elbow Piece 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 fitting for signs of heaving or settling, which may indicate axial thrust movement.
Annually, perform a detailed inspection including the seals, bolt condition, and coating integrity. Perform a torque verification check on flanged connections to ensure the specified clamping force is maintained.
3. Lubrication
The DFT17 Q Elbow Piece is a mechanical connection device and requires no lubrication after installation.
Sealing components and connection faces should be kept clean during storage and installation to ensure proper seating.
4. Seal and Gasket Replacement
Replace gaskets, seals, 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 elbow piece 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.
