PP CORRUGATED SEWERAGE PIPES

PP corrugated sewerage pipes for underground water drainage and pressure-free sewerage systems are manufactured in a Block Copolymer polypropylene (PP) extrusion process, securing a high rigidity level.

Two-ply corrugated PP pipe consists of two layers of material. The outer wall of the pipe is made of two pipes, connected alongside the entire perimeter. The connection is executed in a special technological process.

The outer corrugated wall of the pipe is black. The corrugated rings have an oblong trapezoid cross-section. The size of the rings and the distance of their separation are relative to the pipe diameter and the rigidity level. The inner side of the ring is hollow, and the inner surface of the pipe is smooth, coloured green. The nominal diameter of the pipe (DN) is the inner diameter (ID). Pipes supplied to diameter range DN 200 – 800 mm are manufactured as 6m rods, with integrated connector.

The pipes bear permanent marking in accordance with SRPS EN 13476-3:2009 standard.

  • Marking of standard: SRPS EN 13476,
  • DN / ID,
  • Kind and type of material,
  • Manufacturer marking and year of manufacture.

Two-ply corrugated PP pipe is manufactured to different degrees of perimeter circumferential firmness, in accordance with SRPS EN ISO 9969. The standard firmness of the ring is 4 kN/m2, 8 kN/m2 and 16 kN/m2.

Ring firmness of 10 kN/m2 is supplied based on the customer’s requirements. Corrugated PP pipes are an excellent choice when dealing with the highly demanding loads and site conditions.

Some of the advantages of two-ply corrugated PP pipes include:

  • Long service life,
  • Simple and safe handling and installation,
  • Excellent hydraulic qualities,
  • Excellent mechanical features – very high resistance to mechanical impact at low temperatures and excellent characteristics at high temperatures,
  • High resistance to temperature changes – the pipes are resistant to temperatures of up to 60 ºC, and temporarily of up to 900C,
  • High resistance to wear, contributing to low consumption over a long period of use ,
  • Light weight of the pipes – enabling cost –efficient, simple and and safe handling and installation,
  • Complete discharge system – all of the elements of the system are made from the same material,
  • Flexibility in tailoring and connecting pipes – the pipes are conducive to all the standard methods of processing and jointing,
  • Low cost for the entire system,
  • Flexibility of the pipeline – stability when exposed to excessive load / pressure; even with a relatively thin over-layer, the pipeline is capable of sustaining deformations without suffering damage in its structure; tolerant to ground compaction.

The pipes must not be dragged over the ground or rough surfaces. Pipes made of PP are not affected by low temperatures, and there are no special requirements regarding handling at low temperatures.

Polypropylene pipes may be stored under a roof shelter or in the open, owing to their high UV resistance.

PE dvoslojna korugovane cevi za podzemno odvodnjavanje i kanalizaciju bez pritiska se proizvode procesom ekstruzije od polietilena visoke gustine. Cev je sastavljena je od dva sloja, spoljnja površina je rebrasta, a unutrašnja je glatka. PE dvoslojna korugovana cev se proizvodi u razlicitim obodnim čvrstocama u skladu so standardom SRPS EN ISO 9969. Standardno se izraduje za prstenastu krutost 4 kN/m2 i 8 kN/m2• Na zahtev kupca proizvodi se i 10 kN/m2. PE korugovane cevi su odličan izbor za upotrebu pri najzahtevnijim opterećenjima i pogonskim uslovima.

Two-ply corrugated PE pipes for underground drainage and pressure-free sewerage systems are made by extrusion of high-density polyethylene. The pipe is made from two layers, with the ringed outer surface and the smooth inner surface. The two-ply corrugated PE pipe is made to a range of circumferential rigidity levels, in accordance with the standard SRPS EN ISO 99’09. The standard circumferential rigidity values are 4 kN/m2 and 8 kN/m2, while a higher value of 10 kN/m2 is supplied based on the customers’ requirements. Corrugated PE pipes are an excellent choice for the most demanding loads and site conditions.

The nominal diameter of the pipe (DN) is the inner diameter (ID).

Pipes having a diameter of between DN 50 and 160 (mm) are supplied in 25m and 50m coils, while the diameters of d DN 200 – DN 800 are supplied as straight 6m rods, with integrated connector.

The pipes bear a permanent marking in accordance with SRPS EN 1347ó-3:2009.

  • DN / ID,
  • SN Marking,
  • Kind and type of material,
  • Manufacturer’s marking and year of production.

Polypropylene pipes may be stored under a roof shelter or in the open, owing to their high UV resistance.

All of the PE pipes described above are also supplied as drainage pipes, based on the customers’ requirements.

Drainage pipes provide optimum drainage of the sub-level and non-freezing levels of the soil. They are used to establish drainage systems in the course of construction works and closing of construction sites, by entering an existing course and transporting the water to the main outlet. The connectors are sand-tight, and no rubber sealing is necessary. The standard layout is 6 openings around the perimeter, arranged at 60o. relative to axis.

Partly perforated drainage and sewerage pipes are an ideal combination for collector systems utilising perforated pipes. Depending on the specific requirements, the pipes can be primed to collect any type and volume of surface water, transporting it to any distance. Rubber sealing is inserted in the first channel of the corrugated pipe, while the lubricated collar is pulled over the lubricated rubber ring.

Opening s constitute >50cm2/m of the pipe area, allowing inlet of water. They are arranged symmetrically within each channel of the corrugated pipe. Mechanical laying of pipes is recommended as faster and more precise. In the course of laying, the pipes may be enclosed with filtering material, enabling an increased inlet rate and preventing clogging.
