Half-pipe Jacket Reactor (External Coil Reactor)

     The Half-pipe Jacket Reactor by Yalong Chemical is engineered for processes requiring high temperature, high pressure, and superior heat transfer efficiency. By welding semi-circular pipes to the exterior of the vessel, the heating/cooling medium flows at high velocity in a spiral path. This design not only reinforces the vessel’s structural integrity but also optimizes thermal performance, making it a preferred choice for resin, fine chemical, and polymer industries.

Key Features

High Heat Transfer Efficiency: The reduced cross-sectional area of the coils increases the velocity and turbulence of the medium (thermal oil, steam, or water), significantly enhancing the heat transfer coefficient.

Enhanced Structural Rigidity: The external half-pipes act as stiffeners, increasing the vacuum and pressure resistance of the inner vessel. This allows for a thinner inner shell compared to conventional jackets, optimizing costs.

Reduced Thermal Stress: The design minimizes thermal expansion stress caused by temperature differences between the inner and outer walls, extending the equipment’s service life.

Anti-Scaling & Easy Maintenance: High flow velocity prevents sediment buildup within the coils. The external structure simplifies inspection and hydrostatic testing.

Precision Manufacturing: Utilizing automated welding technology with 100% X-ray flaw detection on welds to guarantee safety under high vacuum or high-pressure conditions.

Applications

Resin Production: Alkyd, epoxy, and polyester resins.

Fine Chemicals: Polymer synthesis, intermediates, and adhesives.

High-Temp Processes: Reactions requiring prolonged heating via thermal oil at elevated temperatures.
