Bulk materials are stored in silos and transported underground for processing using hydraulic or pneumatic pumps, which operate at up to 2 bar (30 psi). The pipeline, typically DN 80 or DN 100, can reach lengths of 50 meters, with larger sizes requiring auxiliary systems. Coupling connections are increasingly used for faster assembly and easier servicing, allowing quick disconnection and reconnection when needed.
Some pipelines are used in vertical mining shaft applications. They can be free-hanging or secured to a shaft wall with brackets. Thermal expansion, static load calculations, diameter reducers, transition pipes and elbows are a few of the many considerations in vertical shaft mining pipe systems. ESSER employs a team of experienced engineers to assist with the conception, design, manufacture and installation of these complex systems.
