External siphon pit Ø315

The RASAN brand siphonic manholes for sanitation are manufactured in PE using the rotational moulding technique.

The technical characteristics of the polyethylene used in the manufacture of these pits are as follows:

Density: 940 Kg / m3

Extension at break (90 mm / min):> 400%

Extension at rupture (90 mm / min):> 400%

Tensile strength (50 mm / min): 21 Mpa

Modulus of elasticity (2 mm / min): 910 Mpa

Hardness: 54 EDGE D

Flowability index (190ºC, 2,16Kg): 3,4 g / 10min

Coefficient of linear expansion: 0.155 mm / m / m ºC

Softening temperature: 112ºC

Thermal conductivity: 0.35 Kcal / mhºC

Polyethylene is also perfectly resistant to all components of domestic and industrial wastewater and is resistant to most acids and aggressive substances (see table of resistance to chemical products).

The RASAN PE siphonic pits are manufactured in diameters 400, 315 and 250. The outlet located at the bottom of the pit in the shape of a pipe is what allows the siphonic function of the pit.

The pit is made of PE and has a diameter of 400, 315 and 250.

They are perfectly watertight pits, which prevent any infiltration of water into the ground or vice versa, making these pits ideal for ground with water tables and preventing the contamination of aquifers.
