Precision Distillation Column Shells

Precision Distillation Column Shells: Custom-Fabricated for Process Excellence

At Kalyros Engineering LLP, we specialize in the precision fabrication of distillation column shells and cylindrical vessels critical to chemical, petrochemical, pharmaceutical, and food processing industries. From our advanced facility in MIDC Bhosari, Pune, Maharashtra, India, we manufacture robust column shells using high-quality sheet metal rolling, longitudinal seam welding, and circumferential joining techniques. The images showcase our expertise: large-diameter cylindrical shells with precise longitudinal welds, tack-welded seams for structural integrity, and smooth internal/external finishes suitable for high-pressure and corrosive environments.

Our Manufacturing Excellence: Engineered for Reliability and Performance

Kalyros Engineering LLP brings decades of heavy sheet metal fabrication experience to produce distillation column shells that meet stringent process and safety requirements:

• Custom Design and Engineering: We collaborate with process engineers and EPC contractors to design shells according to exact specifications, including diameter, wall thickness, length, material grade, and nozzle/flange locations, using advanced CAD and stress analysis tools.
• Premium Material Selection: High-grade carbon steel, stainless steel (304/316/316L), duplex steel, or special alloys chosen for corrosion resistance, temperature tolerance, and pressure ratings in aggressive chemical environments.
• Advanced Fabrication Techniques: Our facility features heavy-duty plate rolling machines, submerged arc welding (SAW), TIG/MIG welding, and plasma cutting to form perfect cylinders with precise circularity. Longitudinal and circumferential joints are executed with full penetration welds, followed by non-destructive testing.
• Rigorous Quality Control: Every shell undergoes dimensional checks, weld radiography/UT, hydrostatic pressure testing, surface finish inspection, and material traceability certification to ensure compliance with ASME, TEMA, and international standards.
• Sustainable Practices: Optimized material utilization and controlled welding processes minimize waste while delivering environmentally responsible fabrication.

The result is distillation column shells that offer exceptional structural strength, leak-proof joints, and long service life in continuous operation.

Applications of Our Distillation Column Shells

Our precision-fabricated shells form the backbone of separation processes across industries:

• Chemical and Petrochemical Plants: Core components in fractional distillation columns for separating hydrocarbons, solvents, and chemical mixtures.
• Oil and Gas Refineries: Used in crude oil distillation units, vacuum distillation columns, and gas fractionation towers.
• Pharmaceutical and Fine Chemicals: Hygienic stainless steel shells for solvent recovery, API purification, and high-purity distillation systems.
• Food and Beverage Processing: Columns for alcohol distillation, essential oil extraction, and edible oil refining.
• Environmental and Waste Treatment: Shells for solvent recovery towers and effluent treatment distillation units.
