Part B,PPR Fittings:Elbow, Tee, Coupling, Valve, End Cap, Reducer, Flange, Crosse, Cap
| PPR Pipe Fitting Hingoa . | Specifications & Applications. |
| Elbow | Elbows are used to change the direction of piping, commonly at 90 mo e 45 degrees, to help the piping system bypass obstacles and adapt to layout requirements. |
| Tee | Tees are used to divert or merge bodies of water through a T-shaped design, creating a branch line from the main line, for multi-point water systems in homes or commercial buildings. |
| Coupling | Couplings connect two pipes to ensure a leak-tight seal and can be used to extend the length of a pipe or repair a broken section. |
| Valve | Valves control the flow of water, such as ball valves (to quickly shut off the flow of water) and gate valves (to accurately regulate the flow), and are suitable for maintaining and regulating water pressure systems. |
| End Cap | End Caps Seal the ends of pipes to prevent leaks and maintain system pressure in situations where unused orifices need to be closed. |
| Reducer | Reducers connect pipes of different diameters, balancing flow rates and pressures and providing smooth transitions to accommodate customized piping systems |
| Flange | Flanges connect pipes to other components (e.g., valve, pumps) and allow for quick disassembly and reassembly for systems that require frequent maintenance or inspection. |
| Crosse | Crosses create multi-branched lines on mains through four-way connections for multi-point distribution of complex water systems. |
| Cap | Caps temporarily or permanently close off the end of a pipe for future expansion or modification of the piping design. |
Applications of PPR Fittings:Elbow, Tee, Coupling, Valve, End Cap, Reducer, Flange, Crosse, Cap
Residential and Building Water Supply and Drainage Systems
Household water supply system: used in household water supply pipe, especially in drinking water system. PPR pipe and fitting especially suitable for medium flow of water delivery.
Drinking water delivery (hot and cold water system)
Radiant floor heating network (oxygen barrier type special piping)
Solar hot water circulation system
PPR Tube Used In Industrial Transfer System .
Industrial plumbing system: It is suitable for some industrial piping systems in low and medium temperatures, such as liquid transport in chemical and food industries.
Food-grade liquid conveying(dairy/beverage production line)
Air-conditioning system: In air-conditioning cooling and heating systems, the pipes are commonly used for condensate discharge, tafe 'a e vai vela,mo e ngaahi me'a pehē.
Acid and alkali media transport (chemical corrosion-resistant type)
Special Applications of PPR Pipeline
Agricultural irrigation system: due to the stable and corrosion-resistant material of PPR pipe, it is also used in farmland irrigation, horticultural irrigation and other occasions.
Fire-fighting system: sometimes it is also used in the construction of fire-fighting water pipelines, especially in some small and standardised fire-fighting facilities.
Swimming pool circulating water treatment
