Feature of PP production

The polypropylene pipeline system for water drainage has the excellent advantages of lightweight, innocuous, anticorrosion, long lifespan, high concussion resistant, etc.

The characters of polypropylene super silencing drainage pipe:

Superior silencing performance:

Modulating the density and microstructure of the pipe, and absorbing and preventing output of the sound wave according to add special raw material that excelled than cast iron and other kinds of UPVC pipe for water drainage.

Strong chemical anticorrosion:

The acid-resistant can reach PH2 and alkali-resistant can reach PH12 of the inner layer of pipe. Chemical liquid from PH2 to PH12 is feasible for outputting through the PP pipe.

Excellent high temperature resistance:

Polypropylene resins of silencing drainage pipes have higher Vicat softening point which is greater than 140℃ while can be boiled; Core of polypropylene after modification has higher melting point and its Vicat softening point is above 150℃, in which is greater than PVC (about 80℃); therefore, polypropylene silencing drainage pipes can convey hot water whose temperature up to 95℃ while PVC drainage pipes cannot transport water which is less than 40℃.

Good resistance to impact strength:

Rigid outer layer can protect middle layer while also gives the pipes good resistance to tensile strength. Polypropylene itself has excellent elastic property: it cannot easily be able to have any cracks when it bears with greater impact force, in another words, the pipes cannot appear with cleavage when they are being distorted.

Advanced way of flexible connection:

Sealed rubber ring inserting connection, easily fix and disassemble. Good nature of flexibility and sealing, do not need adapter fittings. Furthermore, avoid that noise transferred to next fittings when running water rush wall of pipe.

Good capability of environment protection:

Avoiding environment pollution because of in-noxious capability, do not need connection glue, and PVC-U connection glue is harmful last for 15 years.

Strong capability of anti-earthquake:

Satisfy the requirement of transverse and upright moving or distortion for building.

Long lifespan:

It can be used more than 50 years, do not need to maintenance.

Application area:

1.      Pollution and waste water sewerage in construction house, wind, raining sewerage.

2.      School. Office building, student apartment, hospital, nursing home.

3.      Hotel, restaurant, Embassy, villa, high level house building.

4.      High temperature waste water sewerage in spring, project change item, family decoration, industrial building, and so on.

Comparison between PP super silencing sewerage and other plastic pipe:

There are three sources about the noise in sewerage pipe:

1.      Water stream impact the wall of pipe, so cause the vibration of pipe.

2.      Water stream could cause air squeeze fast

3.      Water fluent inside of the pipe.

The middle of viscoelastic material to absorb and isolate the sound of air compression and water, at the same time, the special viscous-elastic can effectively absorb micro—structure noise, the formation of different density of material inside of interface of multi-reflection acoustic reflex, stop the sound wave spread, inside of mute pipe smooth, so reduce the noise to the minimum about the water impact the wall of pipe, so the pipe vibration significantly less than other plastic pipe and cast iron pipe, the mute use non-adhesive flexible rubber ring socket connection, the flexible rubber ring could effectively absorb the vibration, By the "Institute of Acoustics, Chinese Academy of Sciences" and "National Chemical Building Materials Test Center" noise detection,

Under the same conditions, PP super silent drainage system better than the cast iron drainage pipe quiet performance, the noise frequency band of conventional drainage cast iron pipe is lower than 1 ~ 2dB.
