Stainless Steel Half-pipe Jacket Reactor (External Coil Reactor)

The Half-pipe Jacket Reactor is a professional chemical equipment specifically designed for high-pressure, high-temperature, and high-efficiency heat exchange. By welding semi-circular pipes to the exterior of the vessel, the heating or cooling medium (such as thermal oil, steam, or water) achieves high-velocity turbulent flow within the coils. This design offers superior thermal performance and structural integrity, making it ideal for resin synthesis, polymer materials, and fine chemical industries.

Key Features

• Enhanced Heat Transfer: The half-pipe design reduces the cross-sectional area of the medium flow path, significantly increasing flow velocity and turbulence, which results in a much higher heat transfer coefficient than conventional jackets.

• Reinforced Structural Rigidity: The external coils act as “ribs,” enhancing the vessel’s resistance to pressure and vacuum. This allows for a thinner inner shell while maintaining the same pressure rating, optimizing material costs.

• High Pressure Resistance: The coil-jacket design is better suited for high-pressure media and exhibits lower thermal stress compared to standard full jackets.

• Top-Driven Agitation: Equipped with a high-performance motor and gearbox, the agitator can be customized (anchor, frame, or turbine) to meet specific process viscosity and mixing requirements.

• Corrosion Resistance: Constructed from high-grade SS304 or SS316L stainless steel, featuring a polished or pickled surface finish for durability and ease of cleaning.

Applications

• Synthetic Resins: Alkyd, epoxy, polyester, and phenolic resins.

• Fine Chemicals: Production of adhesives, additives, and chemical intermediates.

• High-Pressure Processing: Reactions requiring rapid heating/cooling cycles or high-temperature oil circulation.
