In construction and decoration, PP tees are key "branch connectors" for PP pipeline systems, enabling fluid diversion/confluence and flexible connection between main and branch pipes. Their connection follows three core steps for stability and leak-proofing. First, component matching and pre-processing: select PP tees based on pipe diameters, and choose types such as straight tees (90° branching) or lateral tees (45° for tight spaces). Trim pipe ends flat, remove burrs, and clean pipe/tee surfaces to avoid impurity-related leaks.
Connecting Method
The main connection method is hot-melt welding, ideal for pressure-bearing pipelines. Heat a machine to 200-230℃, insert pipe ends and tee sockets into matching dies, heat 3-5 seconds, then quickly join and hold 10-15 seconds to cool—forming an interface stronger than the pipe itself. For non-pressure scenarios, adhesive connection works: apply PP pipe adhesive to pipe outer walls and tee inner walls, insert and rotate slightly, then cure 5-10 minutes for quick assembly.
PP tees have notable advantages. Strong branching stability: their integrated design avoids pipeline weak points, and hot-melt connections boost integrity, reducing leakage—critical for hidden wall/floor pipelines. Space adaptability: various types fit needs, e.g., lateral tees for narrow kitchen cabinets, reducing tees to match main/branch flow demands. Corrosion resistance & durability: they resist domestic wastewater and mild acids/alkalis, with smooth inner walls preventing blockages; service life reaches 15-20 years. Cost-effectiveness: low raw material costs, prices lower than metal tees, and lightweight eases transport and handling.
Residential decoration uses them in water supply/drainage—kitchen straight tees connect main pipes to sink/water heater branches; bathroom reducing tees split drains for showers/washbasins; lateral tees for hidden floor pipelines avoid floor heating conflicts. Public buildings (malls, offices) use large-diameter tees for main systems—water supply tees branch to floors for even pressure; drainage tees link horizontal pipes to vertical risers. Old building renovations use reducing tees to connect new PP main pipes to existing small-diameter branches, cutting costs. Rainwater systems use tees to split roof collection pipes into downspouts, speeding discharge.
