HDPE Spigot Tee Fittings | Leak-Proof HDPE Fittings Supplier | Payal Irrigation
An HDPE Spigot Tee is a three-way pipe fitting that is installed to form a branch connection in a high-density polyethylene (HDPE) pipeline system. It is provided with 3 spigot ends for butt fusing to form a strong, permanent fit together of the fitting and the HDPE pipe. HDPE Spigot Tees are among the most common fittings in water supply systems, agricultural irrigation, city pipelines, industrial pipes and other fluid systems requiring reliable branch connections and leak-free joints.
Payal Irrigation’s HDPE spigot fittings are available in different applications and pipeline layouts. Choosing the right size tee, pressure rating, SDR/PN rating and fusion parameters is critical in order to ensure long-term pipeline performance.
What is an HDPE Spigot Tee?
An HDPE Spigot Tee is a tee fitting used to join three sections of an HDPE pipe. There is usually one main inlet, one main outlet and a 90 degree branch outlet. This enables the pipeline to be split into a separate branch with only a single fitting.
The spigot ends are formed to be fusion-welded to matching HDPE pipes or other spigot fittings. If it is prepared correctly, the pipe and fitting can be connected as a continuous polyethylene pipe fitting.
How Does an HDPE Spigot Tee Work?
The HDPE Spigot Tee is designed to form a branch connection in a pipeline:
- The pipe ends and tee spigot to be prepared for the HDPE pipe are cleaned.
- The mating surfaces are set up in an appropriate butt fusion machine.
- Appropriate fusion equipment is used to heat the surfaces.
- The heated surfaces are pressed together under controlled pressure.
- The joint is allowed to cool for the specified time period.
- The fusion joint created is permanently bonded.
- Fusion parameters should be based on the manufacturer of the pipes and fittings and relevant HDPE fusion standards.
Key features of HDPE Spigot Tee
The best HDPE Spigot Tee will offer:
- Three-way pipeline connection
- Spigot-end construction
- Able to be joined by butt fusion welding
- Strong and leak-resistant fused joints
- Corrosion resistance
- Resistance to compatible fluids with chemicals
- Lightweight in comparison to other metal fittings
- Smooth flow within the interiors
- Ideally designed for sub-ground pipe installations
- Long service upon proper specification and installation.
HDPE Spigot Tee vs HDPE Equal Tee
HDPE Spigot Tee is different from HDPE Equal Tee.
- An HDPE Spigot Tee is the type of connection that uses spigot ends for fusion joining.
- HDPE Equal Tee is the branch geometry of all 3 outlets are the same nominal size.
Hence, a fitting can be said to be an HDPE Spigot Equal Tee if it has spigot ends and three equal sized outlets.
For example, a 63 mm × 63 mm × 63 mm tee would generally be considered an equal tee, while a 110 mm × 110 mm × 63 mm configuration would be a reducing tee.
HDPE Spigot Tees come in various sizes
here are several dimensions of HDPE Spigot Tees depending on the manufacturer and use. Common configurations can include equal and reducing sizes.
- Before ordering, confirm:
- Nominal pipe diameter
- Tee outlet size
- SDR rating
- Pressure and/or PN classification where appropriate
- PE grade
- Connection method
- Applicable standards
Never announce specific sizes or pressure ratings on the product page if they are not the exact range that you offer.
HDPE Spigot Tee installation
Proper installation is vital for dependable operation. Pipe and fitting surfaces must be clean, free from contamination before fusion. Correct set-up is required to avoid putting stress on the joint.
Fusion process to be carried out by trained personnel with appropriate equipment. The heating temperature, interface pressure, heating time, joining pressure, cooling time and other parameters shall be performed in strict accordance with the manufacturer’s specifications and standards.
Once installed, the pipeline should be inspected and tested following the commissioning procedure as agreed to with the project.
