Ductile iron pipe plants need dust and fume capture at the process stages present on the production line. These can include cupola or induction-furnace melting, metal transfer, centrifugal casting and finishing operations. Hood arrangements must allow access for charging, tapping and maintenance.
Annealing and zinc or bitumen coating require assessment of the gas and fume characteristics. Cement lining and dry-material handling can require local dust extraction at feeding, mixing and transfer points. Bag filters, extraction ductwork and centrifugal fans are selected for each duty; particulate collectors alone are not a complete treatment solution for every gas or vapour.
System selection starts with the pipe-production process, capture locations, airflow, temperature, dust loading and applicable consent conditions. TECHFLOW can review the extraction and particulate-filtration requirements with the plant team.
Pulse jet filters, furnace fume extraction equipment and centrifugal blowers shown on this page are considered according to the process duty. Final scope and performance requirements are established in the project proposal.
