Producer: B&BC a.s. Monolithic seamless shaft bottoms B&BC Excelent DN 800- DN 1500 can be produced with any cunette shape or height as well as with any type and location of shaped joints for branch pipelines. Cunette and adjacent lining can be made from concrete, basalt or stoneware. Products have valid Railway Infrastructure Administration (SŽDC) Certificate. Shaft bottoms are manufactured from C 40/50 XF4+XA1 concrete, custom made from XF4+XA3 concrete following the Czech Technical Standards.
Producer: B&BC a.s., Czech Republic Channeled pipe with integrated rubber sealings in the joint combines inner capacity profile and smaller dimension channel in the bottom part of flow profile (in water-stream) for transfer of smaller flow in higher speed. Channeled pipes are advantageous for their hydro-dynamic parameters, i.e. transfer of small flow (Q [m3/s]) by high speed (v [m/s]) – compared to the classical round profile without channel.
Výrobce: B&BC a.s., Czech Republic Channeled pipes with integrated sealings combine inner profile of circular, larger dimensions pipes with channel of smaller dimensions (in the bottom part of flow profile). It brings a combination of circular and egg-shaped profiles hydraulic properties. Pipes are manufactured from C40/50 FX4+XA1 concrete, custom made from XF4+XA3 concrete. The entire flow profile is lined by basalt fittings.
