The DFT12 PT Three End Flanged T Piece is an essential pipeline fitting specifically engineered to facilitate a secure, leak-free connection for branching off a main water line or creating a stable base for flanged vertical components. Designed to meet the stringent demands of modern infrastructure, this specialized fitting ensures reliable pressure containment, structural rigidity, and long-term durability in complex water distribution and fire protection scenarios.
At the core of the DFT12 PT Three End Flanged T Piece is its robust, three-flanged design, which provides a dedicated connection point for the main flow (two ends) and a lateral connection point (the third end). This heavy-duty structure is crucial for managing the significant hydraulic thrust forces generated when flow direction changes abruptly at the T-junction. The component’s strength ensures the entire assembly remains fixed and secure.
Manufactured from high-strength, corrosion-resistant materials (such as ductile iron) and built with a fixed, heavy-duty body, the DFT12 PT Three End Flanged T Piece is designed to withstand continuous system pressure and demanding burial environments. Its precision-machined flanged ends ensure accurate alignment and a reliable bolted connection to the mating pipes and valves. This component is non-reducing, ensuring minimal flow turbulence at the junction point.
The DFT12 PT Three End Flanged T Piece is ideally suited for applications connecting fire hydrants to the main line, creating valve manifolds, or enabling new branch lines within municipal and industrial networks. Its structural integrity and dependable connection points make it a preferred choice for engineers seeking a high-integrity, standards-compliant solution for long-term network expansion and system stability.
In summary, the DFT12 PT Three End Flanged T Piece offers an optimal combination of structural strength, reliable flow division, and secure flanged integration. With its robust three-flange configuration, corrosion-resistant construction, and focus on branching reliability, this unit stands as a trusted solution for modern fluid control and complex pipeline integration requirements worldwide.
1. General Information
The DFT12 PT Three End Flanged T Piece is designed for the permanent, secure creation of a three-way flanged junction in pressurized pipelines. Proper installation is essential to guarantee safe operation, long service life, and efficient flow branching.
2. Safety Precautions
Installation must be performed by qualified personnel only.
Ensure strict compliance with all local safety regulations and standards concerning working with pressurized pipelines and managing significant thrust forces.
Wear appropriate personal protective equipment (PPE).
Confirm that the pipeline section is fully depressurized and isolated before attempting to install the DFT12 PT Three End Flanged T Piece.
3. Pre-Installation Checklist
Inspect the DFT12 PT Three End Flanged T Piece for any visible damage during transport or storage, paying attention to all three flange faces and the interior coating.
Check that the fitting type, size, and pressure rating match the system requirements.
Verify that the interior is clean and free from debris.
Confirm that all three mating pipe flanges are properly aligned (parallel and concentric) and free from burrs or sharp edges.
Ensure materials for the necessary external thrust restraints are readily available.
4. Installation Procedure
Positioning: Install the DFT12 PT Three End Flanged T Piece at the desired branching location, ensuring all three flanges are correctly oriented for connection.
The fitting should be supported adequately to prevent strain on the main line.
Use the appropriate gaskets suitable for the medium and operating conditions for all three flanged connections.
Align the fitting precisely between the pipeline flanges and insert bolts, tightening them gradually and crosswise in incremental steps on all three connections.
Ensure external thrust restraint (e.g., concrete block) is applied to the fitting’s body to counteract hydraulic forces.
5. Post-Installation
Slowly reintroduce fluid and pressurize the system, checking immediately for leaks around all three flange connections.
If leakage is detected, depressurize the system immediately and verify the flange alignment and re-tighten the bolts following the cross-pattern sequence.
Verify that the thrust restraint is effective under full operating pressure.
Record the installation details, flange torques, and thrust restraint notes for documentation purposes.
Proper maintenance extends the service life of the DFT12 PT Three End Flanged T Piece and ensures continuous structural integrity and leak-free performance. Follow the guidelines below to maximize the longevity of this essential unit.
1. Routine Operation
Visually inspect the DFT12 PT Three End Flanged T Piece area regularly (e.g., annually) for signs of external leakage, soil erosion around the joint, or movement of the piping.
Monitor the structural integrity of the external thrust restraint, looking for cracks or shifting.
2. Inspection Schedule
Monthly, check the visible flange 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 anchor failure.
Annually, perform a detailed inspection by excavating the joint (if buried) to check the flange connections for sustained seal integrity and corrosion.
3. Lubrication
The DFT12 PT Three End Flanged T Piece is a passive structural component and requires no lubrication after installation.
All fasteners should be protected with appropriate anti-corrosion coatings before burial.
4. Seal and Gasket Replacement
The flange gaskets on any of the three ends should be replaced if external leakage is observed that cannot be stopped by re-tightening the bolts to the specified torque.
The structural integrity of the fitting itself should be verified if excessive stress or external force is suspected.
Always isolate and fully depressurize the pipeline section before attempting to replace any connected components.
5. Cleaning
The exterior of the DFT12 PT Three End Flanged T Piece should be kept clean before burial.
After excavation, clean the fitting and inspect the coating integrity before reburial.
6. Storage and Spare Parts
Store spare parts (gaskets, bolts) in a dry, clean, and cool environment, away from direct sunlight and temperature extremes.
Maintain a detailed record of all inspections, bolt torque checks, and repairs performed on the DFT12 PT Three End Flanged T Piece unit.

Frequently Asked Questions about the DFT12?
What are the main advantages of this valve?
The DFT12 PT Three End Flanged T Piece offers structural stability for creating critical pipeline branches, ensuring secure, high-pressure flanged connections in three directions simultaneously, which is necessary for complex valve or hydrant manifolds.
Why should I choose this product?
This valve delivers outstanding performance in both sealing and durability, making it a dependable choice for demanding applications. Its straightforward design facilitates easy installation, offering flexibility during system design. With a wide range of material options, it meets the needs of various infrastructure projects, from municipal water networks to industrial facilities.
Why is thrust restraint mandatory for the DFT12 PT Three End Flanged T Piece?
Thrust restraint is mandatory because the abrupt 90-degree change in flow direction at the T-junction generates high hydraulic forces (thrust) that must be absorbed by an external anchor (like a concrete block) to prevent the fitting and connected pipe from separating.
Can the DFT12 PT Three End Flanged T Piece be used to connect pipes with different nominal sizes?
No. The DFT12 PT Three End Flanged T Piece is designed to connect only flanged components of the same nominal size at all three ports, unlike universal couplings which accommodate varying O.D.s.
What is the benefit of a fully flanged tee piece over a welded tee in certain environments?
The fully flanged design allows the DFT12 PT Three End Flanged T Piece to be easily removed or inserted into the pipeline during maintenance or replacement of major valves, offering greater flexibility than permanent welded connections.
