High-Performance Reaction Vessels

Custom-Engineered Pressure & Process Vessels for Chemical, Petrochemical & Fine Chemical Processing

Hexamide Agrotech INC is a premier manufacturer, supplier, and global exporter of heavy-duty Reaction Vessels. Engineered strictly in compliance with ISO 9001:2015 quality systems and ASME Section VIII Division 1 pressure vessel codes, our reaction vessels are built to deliver superior mechanical integrity, highly efficient thermal transfer, and absolute operational safety across demanding industrial chemical environments.

Whether your process requires high-pressure hydrogenation, solvent distillation under full vacuum, exothermic neutralization, or viscous resin mixing, our custom reaction vessels are engineered to withstand extreme temperature fluctuations, high internal pressures, and aggressively corrosive chemical media.

Technical Specifications Overview

Key Features & Structural Engineering Excellence

1. Superior Metallurgy & Pressure Vessel Geometry

Reaction vessels undergo intense mechanical fatigue caused by pressure cycles and chemical exposure. Hexamide reaction vessels are designed using Advanced Finite Element Analysis (FEA) to ensure structural stability and zero fatigue failure:

• Corrosion-Resistant Alloys: Fabricated from low-carbon stainless steel alloys (SS316L) and nickel-based superalloys (Hastelloy C276) to protect against intergranular corrosion, pitting, and stress-corrosion cracking in aggressive acidic or basic environments.

• Precision Formed Dish Ends: Top and bottom heads are hydraulics-pressed and flanged into Torispherical, Semi-Ellipsoidal, or Hemispherical profiles, ensuring maximum pressure rating integrity and smooth fluid drainage.

2. Specialized Thermal Management Systems

Precise temperature regulation is essential for maintaining reaction kinetics, maximizing yield purity, and preventing dangerous thermal runaways:

• Limpet Coil Reaction Vessels: Half-pipe limpet coils welded externally to the vessel body create high-velocity fluid channels for high-pressure steam, thermal oil, or chilled water, providing exceptional heat transfer efficiency.

• Full Jacketed Reaction Vessels: Full jacket construction envelops the shell and bottom dish, providing maximum wetted heating surface area for small-to-medium batch processing.

• Internal Heating/Cooling Coils: Supplemental internal coil circuits provide accelerated direct thermal transfer for ultra-exothermic chemical reactions.

3. Precision Agitation & Fluid Dynamic Control

Mass transfer speed directly dictates process reaction times. Our engineering team custom-pairs drive systems and impellers based on fluid rheology:

• High-Viscosity Reaction Systems: Heavy-duty Anchor impellers fitted with flexible wall-scraping PTFE blades sweep the internal walls to maximize heat transfer and prevent local thermal degradation.

• Gas-Liquid Phase Dispersions: Multi-tier Rushton turbines shear gas streams into fine bubbles to maximize inter-phase contact surface area.

• Solid Suspension & Low Shear: Hydrofoil and Pitch-Blade impellers deliver strong axial flow, keeping heavy solid catalysts uniformly suspended with low energy intake.

Quality Assurance & Non-Destructive Testing (NDT)

To ensure leak-proof performance and zero operational failure on-site, every reaction vessel undergoes multi-stage non-destructive testing at our Navi Mumbai manufacturing plant:

1. Hydrostatic & Pneumatic Testing: 100% hydrostatic pressure testing at 1.5x design pressure across the primary vessel shell, limpet coils, and outer jackets.

2. Non-Destructive Testing (NDT): Dye/Liquid Penetrant Testing (DPT) on all structural weld joints, supported by 100% X-Ray Radiography inspection on main load-bearing seams.

3. Agitator Dynamic Balancing: Impeller and drive shaft assemblies undergo dynamic balancing to eliminate operational vibration, protecting mechanical seals and extending equipment life.

4. Surface Profile Roughness Validation: Verification of internal surface finishes ($\text{Ra} < 0.4\ \mu\text{m}$) accompanied by chemical passivation to guarantee non-reactive, smooth internal walls.

Primary Industrial Applications for Reaction Vessel

Our reaction vessels are deployed across diverse process manufacturing sectors worldwide:

• Chemical & Fine Chemical Synthesis: Organic synthesis, nitration, sulfonation, halogenation, and neutralization processes.

• Resins, Polymers & Adhesives: High-temperature resin synthesis (alkyd, epoxy, polyester, phenolic) and polymerization lines.

• Pharmaceutical Intermediates: High-purity active pharmaceutical ingredient (API) synthesis, crystallization, and solvent extraction.

• Agrochemicals & Specialty Chemicals: Pesticide, herbicide, liquid fertilizer, and surfactant manufacturing.
