description
Grooved straight tee (Equal tee) is an equal-diameter three-way pipe fitting with a grooved connection structure. The pipe diameters of the three interfaces are the same, and it is used in pipeline systems to achieve vertical branch connections of pipelines

application
- Main pipeline diversion system: fire sprinkler piping network, HVAC main trunk pipes, achieving equal-diameter vertical branches to ensure balanced diversion flow.
- Equipment parallel connection: multiple devices in the pump room are connected in parallel for water supply/return, with three-way connectors reducing welding joints and lowering the risk of leakage.
- Space-optimized layout: building mechanical and electrical pipe shafts, ship pipe compartments, compact design (especially short types) saving 30% of installation space.
- Industrial Circulation System: Cooling tower circulation water and chemical medium transportation, with equal-diameter structures to prevent cavitation caused by sudden changes in local flow velocity.
- System Expansion and Renovation: Municipal water supply/industrial pipeline network upgrades, allowing new branches to be added without replacing the main pipeline (e.g., community water supply expansion).
advantages
- Dual types cover all scenarios:
- Short: Suitable for space-constrained areas (such as equipment compartments);
- Standard: Preferred for conventional branches, with less fluid disturbance;
- Long Type (Long) (14“-24”): Designed for extra-large pipe diameters, reducing high-pressure water hammer impact.
- Zero flow loss design: Equal-diameter three-way interface, branch pipe flow attenuation <5%, outperforming unequal-diameter tees.
- Triple sealing assurance:
- Ductile iron body (ASTM A536) resists deformation;
- Grooved ends with dual sealing rings for seismic resistance and anti-loosening;
- Hot-dip galvanized coating (≥80μm) resists chemical corrosion.
- Minute-level installation: Grooved connection requires only 3 steps (align pipes → clamp → bolts), 90% faster than flange connections.
- Full size coverage: 1“-24” meets all needs from residential branch pipes to industrial main pipes, UL/FM certification ensures fire system safety.
packing
- Smart Graded Packaging:
- ≤4 inches: 12 pieces per box, PE bag + bubble wrap, paper box with compartments to prevent collision;
- >4 inches: Single suspended wooden box, three-way interface with EVA protective cap, hollow box design for easy forklift handling.
- Error-proofing Identification System:
- Product body laser-engraved type identification (Short/Standard/Long);
- Outer box labeled with three-color tags for type classification (Blue label = Short type/Green label = Standard/Red label = Long type).
- Revolutionary protection for large items:
- 10“-24” long three-way connectors use a removable steel frame structure, with magnetic dust covers embedded at the interface;
- Equipped with RFID electronic tags, scan to access installation videos and pressucapacity parameters.
- Transportation safety technology:
- Acceleration sensors built into wooden boxes automatically alarm during transportation in case of abnormal vibrations;
- Stack height limit labels (≤3 layers) printed on all six sides of the box.
