Our products are equipped with high-strength rubber O-rings from German companies CORDES GmbH and Dichtungstechnik GmbH (DS), which officially guarantee the service life of their products for 80 to 100 years. These O-rings have significant advantages in ensuring the tightness of the pipeline in the butt joints.

Reinforced concrete pipes are used in the construction of embankments, dams, highways, railroad tracks. They are used in civil and industrial engineering, when laying water supply and sanitation systems (sewerage, wastewater, stormwater, sanitary wastewater, amelioration), in the construction of hydraulic structures and for pumping liquids under pressure and by gravity.

According to GOST, in territories with seismicity of 7 and 8 points, only pipes joined using rubber O-rings can be used. Sapa Su pipes are equipped with rubber O-rings and, thanks to an increase in pipe wall thickness of up to 50 mm, they withstand seismicity of up to 9 points.
