6-03 25-196-B Attachment A - Metal Canister Drawing.pdf

This is a technical drawing and specification document for metal canisters used in activated carbon and exchange services for the North Texas Municipal Water District under contract 25-196-B. The document details specifications for activated carbon filter containers with a 470-gallon open-head drum capacity, including precise dimensional requirements, material specifications using CRCO carbon steel per ASTM A1008, and operational parameters such as maximum flow rate of 300 CFM, maximum temperature of 140°F, and maximum pressure of 3 PSIG. The drawing shows detailed measurements, cross-sections, and assembly instructions for the cylindrical containers with covers, gaskets, and coupling mechanisms.

The specifications indicate these canisters are designed for plenum flow/PVC screen distribution systems with specific material thickness requirements (1.5mm or 0.0543-0.0590, 16 gauge) and finish requirements including exterior urethane enamel paint and interior epoxy phenolic coating. The document includes detailed closure instructions, bolt specifications, and part lists showing components such as reinforcement rings, NPT fittings, gaskets, and mounting hardware. The containers appear to be industrial-grade water treatment equipment designed to house activated carbon media for water filtration applications within the municipal water system.
