Dipping tubes to Saudi Arabia


YANBU Cement Co, one of the most important cement groups in Saudi Arabia, has entrusted Estanda with the manufacture of dipping tubes for raw cement preheating cyclones.

This project, which has now been completed, was carried out on one of the group’s cement plants, and consisted of the complete installation of dipping tubes for the five cyclone stages (cyclone C2, C3, C4, C5 and C6).

The selected designs and materials consisted of high temperature and oxidation resistant refractory alloys, with high chromium (Cr) and nickel (Ni) content, taking into account the extreme conditions from the outlet gases coming from the clinker kiln (calcination).

Estanda, a guarantee of quality, experience and knowledge in the manufacturing of dipping tubes and dipping valves
