Production program of PE-HD anchor pipes for drainage and street sewerage
The wall of the pipe consists of a profiled outer layer and a flat inner layer, which are welded between the ribs and form a homogeneous wall. The outer profiled layer greatly improves the mechanical properties of the pipe and significantly increases the stiffness of the pipe in the radial direction. The flat and smooth inner side, in addition to additional safety, also enables ideal hydraulic properties and thus large unobstructed flows. Water inlet openings are securely installed in the groove between the two ribs, so that water capture is optimal with a reduced possibility of clogging of the openings. The water intake slots shall be between 0.8 mm and 1.4 mm wide, and the total open area of the water inlet slots shall be at least 50 cm2 per meter of pipe length.
The color of STIDREN pipes and fittings is black with a green line indicating the laying angle.
Pipe circumferential stiffness:
SN ≥ 4 kN/m2 (EN ISO 9969) or
Sr24 ≥ 31,5 kN/m2 (DIN 16961)
The pipes are manufactured in accordance with standards STS-06/050 (Form D) and DIN 16961/1.
Purpose of drainage pipe systems
The pipes are extremely resistant to static and dynamic mechanical loads, as they are designed for the most difficult operating conditions and thus especially suitable for drainage of large motorway and airport areas. The versatility of pipes – drainage, collection, sewerage and drainage of water enables additional simplifications in the construction of pipe systems and a significant reduction in implementation costs.
The water inlets are evenly distributed over the entire circumference of the pipe (360 °). Stidren D pipes are intended for drainage drainage of the terrain and are especially suitable for drainage of road and railway facilities, airports, tunnels, as well as landfills and other constructions due to their high resistance to backfill material pressure and dynamic surface load of vehicles.
The water inlet openings are distributed along the upper circular 220 ° circumference of the pipe. Stidren DD partial drainage pipes are also intended for drainage of the terrain and retain all the excellent properties of STIDREN D full drainage pipes. For proper orientation of the pipe when laying and backfilling, they need marking green lines that are on the top of the pipe.
The water inlet openings are distributed along the apex circular circumference of the pipe within a 120-degree center angle. Drainage sewer pipes Stidren DK have the function of drainage pipes, and at the same time perform the task of collecting – sewer pipes. The joints between the pipes and the connecting pieces are sealed with sealing rings so that the connections are watertight. For proper orientation of the pipe when laying and backfilling, they need marking green lines that are on the top of the pipe.
STIDREN drainage pipes are produced in the following dimensions:
|Nominal diameter DN (mm)||Outer diameter d (mm)||Inner diameter d (mm)||Pipe length (m)|
