Applications of Conical Strainers
Pipeline Commissioning
Protects pumps, valves, and meters during system startup by filtering out welding slag, rust, and debris in newly constructed pipelines.
System Start-Up
Installed during start-up or expansion projects to ensure clean flow through pumps and prevent debris from entering sensitive equipment.
Maintenance Shutdowns
Provides temporary filtration during maintenance or shutdowns, protecting pumps and valves from clogging by debris that may accumulate over time.
Retrofit Projects
Installed in existing systems during upgrades to provide temporary protection until permanent filtration solutions are installed.
Debris Removal
Filters particles like sand, sediment, and welding slag, protecting pumps, filters, and meters during commissioning or maintenance.
Emergency Filtration
Offers immediate filtration in critical situations to protect equipment from sudden debris exposure or pipeline contamination.
