B.PPR Fittings

BST’s products,withith ISO9001:2000, ISO14001:2004,OQS,ISO/TS16949:2002 certificatifications, and PPR pipes and fittings completely meet the standard DIN8077/8078, PE-RT floor-warm pipe system are accord with international standard.<o:p></o:p>

Polypropylene pipes and fittings for cold and hot water supply, heating, under floor heating, for any liquids and gazes.PPR pipes fiberglass (PPR-FB-PPR),with antibiotic inner layer.

PPR fitting is the occupation of installing or repairing piping or tubing systems that convey liquid, gas, and occasionally solid materials. This work involves selecting and preparing pipe or tubing, joining it together by various means, and the location and repair of leaks.

1）Material:PPR

2)Standard/Criteria: Product standards: Din8077-8078

3) Product pressure grade: PN2.5Mpa

4) Production temperature: -40°C- +95°C,or -40 °F~203°F

5) Product colors: green, white, gray avaible

6) Product dimensions: 20mm - 160mm

7) Pipes length as a standard - 2 and 4 meters

8)ADVANTAGRE :

1. Healthy, hygienic and non-toxic,bacterial neutral,low cost,

2. High strength &good durability, high pressure resistance&high shock resistance

3.Easy installation,home,residential buildings, hospitals, hotels, schools and office.

4. Light weight.It is only 1 / 9 of steel pipe and 1 / 10 of purple steel pipe, convenient to transport and handle,reducing the carrying cost and construction strength.

5. Environmental: Recyclable

6. lower coefficient of thermal expansion

7.Corrosion resistance  

8.No pipe furring: smooth inner walls reduce pressure loss and increase flow speed   

9.Sound insulation: compared with galvanized steel pipes, 40% reduced 

10.long lifespan：at least 50 years

9) Applications:

-(a) Potable water pipe networks for cold and warm water installations of residential buildings,hospitals, hotels, schools, office buildings and shipbuilding.

-(b) Pipe networks for rainwater utilization systems.

-(c) Pipe networks for compressed air plants.

-(d) Pipe networks for swimming pool facilities.

-(e) Pipe networks for solar plants.

-(f) Pipe networks in agriculture and horticulture.

-(g) Heating pipes for residential housing.

-(h) Pipe networks for industry, transport of aggressive fluids (acid, alkali).

-(i) Transport of liquid foods.

10)Unique Features:

UV Resistance: PP-R pipes and fittings are not ultra-violet resistant and must be covered, lagged or painted if being installed outdoors. The pipe can be painted using an etch primer to prepare the surface, and then applying a UV stable paint

Head loss: The internal surfaces of the pipes and fittings are smooth, so limestone or other deposits can not form and therefore head loss is reduced to a minimum

Acoustic: The material elasticity and high insulation capacity mean a considerable reduction in the noise of the installation even when there is water hammering

Abrasion: PP-R pipes allow high velocities of the transported fluid, up to 7m/s, without the problem of erosion, even in the presence of acid and alkaline substances with PH values between 1 and 14

Energy saving: The reduced heat dispersion, in association with a low thermal inertia, allow to supply hot water even if the pipe has not yet reached the average operating temperature. The energy saving is in the range of 10% to 20%

Conductivity: The PP-R system is a poor conductor of electricity; therefore perforation phenomena caused by stray currents are unknown. Since PP-R is a poor conductor of heat, condensation and heat dispersion of the transported fluid are considerably reduced

Flexibility: The flexibility and resilience of the PP-R pipelines allow their use also in seismic areas. The low specific weight means easy transport and handling. The system can be used in traditional site installation, for the preparation of prefabricated constructions and in the creation of modules or fitted walls.

Welcome,we are right here waiting for your voice.
