Advanced PPR Plumbing Components Precision Brass Fittings

Introduction of PPR Fittings/Brass Fittings

PPR (Polypropylene Random Copolymer) pipes and fittings,the third generation of polypropylene pipes, have become the first choice in construction,water supply system,drainage system world wild.The pipes, produced using advanced random copolymerisation technology, achieves a perfect balance of temperature resistance, compression resistance and hygienic properties thanks to its unique molecular structure.

1. Excellent corrosion resistance: Brass fittings has oxidation resistance and acid and alkali resistance, suitable for water, steam, oil and some chemical media transportation.

2. High strength and ductility: Brass fittings can withstand high pressure (up to 25MPa), and can adapt to the thermal expansion and contraction of the pipeline system.

3. Antibacterial and environmental protection: Brass fittings has a natural antibacterial property, especially suitable for medical, food processing and other hygiene requirements of the scene.

4. Long life: life under normal conditions of use can reach more than 50 years, low maintenance costs.

5. 100% recyclable: in line with the concept of green sustainable development.

Part B,PPR Fittings/Brass Fittings

PPR Pipe Fitting Name ‌	Specifications & Applications‌
‌Elbow‌	Elbows are used to change the direction of piping, commonly at 90 and 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., valves, 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/Brass Fittings

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  

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, hot water circulation,etc.

Acid and alkali media transport (chemical corrosion-resistant type)  

Special Applications

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  

Packing and Shipment

Depends on the products and qty,we could make the packing of coiling,rolls,bundle packing,crates or boxes,etc.

Shipment:By sea,railway,by air or as customer’s request.
