HDPE pipe tee fittings are chemical fittings with three ports, i.e. one inlet and two outlets, or two inlets and one outlet design. These fittings can be used at the convergence of three identical or different pipelines to connect and extend piping systems by changing the direction of the fluid. The tee can be T-shaped or Y-shaped, with equal or reducing orifices, and is suitable for a wide range of application scenarios.
Classification
The classification of HDPE pipe tee fittings mainly includes same-diameter tee and reducer tee.
HDPE Equal Tee is a tee with the same diameter for both main and branch pipes.
HDPE Reducing Tee is a tee where the diameter of the branch pipe is smaller than the diameter of the main pipe.
In addition, according to the butt form, the tee can be divided into.
Butt-welding Tee: Tee fittings that are butt-welded to the connecting fittings.
Socket Tee: Tee fittings that are welded or fused after inserting the connecting fittings into each end of the tee.
Advantages of HDPE pipe tee fittings
1. Good chemical corrosion resistance: able to withstand the corrosion of a variety of chemical media, including PH2 to PH12 chemical reagents, suitable for a variety of chemical environments.
2. Good low-temperature impact resistance: safe to use in the temperature range of -60℃ to 60℃, with good impact resistance.
3. Energy-saving and environmental protection: the material can be recycled and reused, with no toxicity, no odor, and no harmful gases produced during combustion, which is in line with the sustainable development strategy.
4. No leakage at the joints: the use of hot fusion fittings connection, essentially to ensure that the PE piping system interface material, structure, and pipe body itself are of the same nature, to achieve an integrated connection.
5. Resistant to vibration and end-load: PE piping system has better end-load resistance after connection by fusion method, and no joint leakage will occur.
6. Long service life: there is no environmental stress cracking problem, and the service life in the indoor environment can reach 50 years.
Appliance
The application of HDPE pipe tee fittings is not only limited to ordinary pipeline connections but also plays an important role in the dynamic header operation of oil and gas pipelines.
For example, in the operation of oil and gas pipelines, replacement of pipe sections, connection, increase of valves, station renovation, and other needs, HDPE pipe tee fittings play an important role in the operation of oil and gas pipeline dynamic header. fittings ensure the safety of the fire-connected operation through the process of “unilateral blocking + airbag isolation”, etc. The fire isolation is carried out through the clever application of pipe tee and the addition of a nitrogen airbag, which effectively isolates the flammable and explosive media. By skillfully applying the pipe tee and installing a nitrogen gas bag to isolate the fire, it can effectively isolate the flammable and explosive medium and other harmful gases, and guarantee the safety of the operation area.
In addition, it is also widely used in the fields of municipal engineering, underground buried drainage in residential areas, sewage pipes, pre-buried pipes of highways, as well as agricultural irrigation water transmission and flooding, and drainage and ventilation pipes of mines and buildings. These applications show the important role of HDPE pipe tee fittings in improving project efficiency and guaranteeing project quality.
