In construction and decoration, PP reducers are key transition connectors for PP pipelines, linking different-diameter pipes to ensure smooth fluid flow between main and branch pipes. Their connection has two core stages. First, preparation and specification selection: choose concentric reducers (for vertical pipes, uniform fluid distribution) or eccentric ones (for horizontal pipes, avoiding air/sediment buildup) based on installation direction and diameter pairs. Trim pipe ends flat, remove burrs, and clean pipes/reducer sockets to prevent leakage from impurities.
Connecting Method
The main connection is hot-melt welding, fit for pressure-bearing pipelines (e.g., domestic water supply). Heat a machine to 200-230℃, insert large/small-diameter pipes and corresponding reducer ends into matching dies, heat 3-5 seconds, then join firmly and hold 10-15 seconds to cool—forming an interface stronger than the pipes. For non-pressure scenarios (temporary decoration drainage), adhesive connection works: apply PP pipe adhesive to pipe outer walls and reducer inner walls, insert, rotate slightly, and cure 5-10 minutes for quick assembly.
PP reducers have notable advantages. Their tapered structure avoids pressure loss/turbulence from sudden diameter changes, vital for stable water pressure. Strong sealing & stability: hot-melt connections eliminate gaps, reducing leakage risk—critical for hidden wall/floor pipelines. Unlike makeshift methods, their integrated design avoids weak points. They resist domestic wastewater (detergents, grease) and mild acids/alkalis, with smooth inner walls preventing blockages; service life is 15-20 years, matching PP pipelines. Cost-effectiveness & ease of use: cheaper than metal reducers and lightweight, easing transport and installation.
Residential decoration uses them in water supply/drainage—kitchen concentric reducers connect main pipes to faucets/water purifiers; bathroom eccentric reducers link horizontal drains to washbasin pipes, avoiding sediment. For under-floor heating, concentric reducers transition main pipes to radiator branches. Public buildings (malls, offices) use large-diameter reducers in central systems—water supply reducers balance floor pressure; drainage reducers connect branch pipes to main risers. Old renovations use them to link new PP main pipes to existing small-diameter metal branches, cutting costs. Rainwater systems use reducers for roof collection to ground pipes, preventing waterlogging.
