1. Petrochemical & Chemical Processing: Cleaning reactor internals, heat-exchanger bundles, fractionation columns and piping to remove catalyst fines, polymer residues, sulfur deposits and corrosion products. Both on-line and off-line wash cycles restore throughput and heat-transfer efficiency without full disassembly. 2. Power Generation: Descaling boiler tubes, economizer coils and feedwater piping to eliminate scale buildup and under-deposit corrosion. Automated chemical skids circulate heated acid/alkaline solutions and use mechanical tube cleaners to restore thermal performance during planned outages. 3. Marine & Offshore: Cleaning shipboard seawater cooling circuits, firemain lines, ballast and bilge piping. Off-hull bays allow caustic detergent washes, followed by high-pressure rinsing and hot-air drying—critical for refit yards and new-build commissioning. 4. Municipal & Wastewater Treatment: Flushing clarifier skimmer arms, digester piping and sludge lines of organic and inorganic deposits. Periodic chemical treatments dissolve biofilms and precipitates, reducing downtime and ensuring compliance with discharge permits. 5. Food & Pharmaceutical (CIP/SIP): Validated Clean-In-Place cycles for stainless steel process lines, tanks and filter housings. Sequences of caustic, acid, disinfectant and rinse phases remove product soils and biofilms without disassembly, meeting FDA/GMP traceability requirements. 6. Heavy Manufacturing & Automotive: Cleaning hydraulic manifolds, gearboxes, stamping dies and CNC spindles of oils, greases and particulates. Heated alkaline detergents, ultrasonic agitation and closed-loop filtration achieve ISO 4406 cleanliness levels prior to re-assembly or coating. 7. Mining & Minerals: Descaling slurry pumps, flotation tank piping and filter press manifolds of mineral scale and hydroxide deposits. Acid or chelating washes restore pump performance and extend component life.

Introduction The Chemical Cleaning Bay is a purpose-built facility installed within an existing 150 ft × 60 ft workshop to perform combined mechanical and chemical cleaning of pipes and fittings made from MS, SS, Copper, Cupro-Nickel, Titanium, and Aluminum alloys. It serves vessels—ships, submarines, dredgers, and other marine platforms—during both refit and new-construction phases, ensuring components are free of scale, rust, old coatings, and other contaminants prior to assembly or repair. Key Features ▹ Integrated Shot Blasting & Dust Extraction: A fully enclosed shot-blasting chamber fitted with high-capacity dust extraction removes oxide scale, rust, paint, and other surface deposits effectively. ▹ Robust Construction: Cabinet fabricated from 3.15 mm thick, welded and folded MS sheet delivers high strength, rigidity, and long service life. ▹ Sealed Access Door: Hinge-type door (2000 mm W × 4500 mm H) with airtight seals and locking provisions to prevent dust escape and ensure operator safety. ▹ Hot Chemical Washing: ON/OFF-type hot water generator delivers up to 600,000 kcal/hr for heated chemical baths, enhancing removal of oils and greases. ▹ Automated Circulation & Filtration: 5.5 kW circulation pump (25 m3/hr at 40 mLC) with 1.1 kW make-up pump maintains fluid turnover; scrubber tower and regenerative dryer ensure clean, dry components post-treatment.
