Glass Lined Reactor, Half Pipe Coil Jacketed

Corrosion-resistant reaction vessels with half pipe wrapping around the outside wall of the vessel

Half pipe coil jacketed glass lined reactors are widely used in chemical, petrochemical, pharmaceutical, dye, pesticide, and food industries. Compared with conventional jacketed glass lined reactors, the half pipe coil design offers several clear advantages in terms of safety, heat transfer, rigidity, and corrosion resistance.

  • Capacity range: 50 – 80,000 L
  • Maximum pressure: up to 16 bar (atmospheric to high pressure)
  • Operating temperature range: –19 °C to 200 °C
  • Standards: CE/JIS/ASME/GB

  • Vessel type and safety

    In half pipe coil jackets, the heating or cooling medium flows in a steady way, which makes them safer than conventional jackets. The design also helps the reactor stay more stable when working under pressure.

  • Heat transfer performance

    The heat exchange area of a half pipe coil is roughly one-third smaller than that of a conventional jacket, but because the medium flows two to three times faster, the overall heat transfer is much more efficient. Conventional jackets often have problems such as flow disturbance, short circuits, or uneven heat transfer. The half pipe coil design avoids these issues and works especially well with liquid heating and cooling media. For steam heating, though, conventional jackets can sometimes be a better option because of the way steam interacts with the grouped pipes.

  • Structural rigidity

    The design of the half pipe coil not only strengthens the vessel but also improves its stability. With an open-flow layout that allows high-speed circulation, it helps reduce external pressure on the inner wall of the reactor, resulting in greater overall mechanical strength.

  • Corrosion resistance

    When cooling water is used, conventional jackets are more likely to suffer corrosion from ions like H⁺ and Cl⁻, which can cause deposits to build up and damage the walls. The half pipe coil design avoids this problem thanks to its faster flow through the upper and lower channels, reducing the chance of buildup and protecting the walls from corrosion.

Open-top glass lined reactors consist of a few important parts: the vessel body, a removable cover, sealing gaskets, and clamps. Sealing gaskets are necessary to form a seal between the cover and the body, while the clamps hold them firmly together, so the reactor stays tightly closed and safe during operation.

The internal design pressure depends on the sealing method. With a packing seal, the vessel is rated for 0.2 MPa. With a mechanical seal, the design pressure can be 0.4 MPa or up to 1.0 MPa, depending on the configuration.

Some glass lined reactor models are equipped with quick-opening manhole covers and dual manholes, to enable easier access for inspection and maintenance. The lid is designed with butt-welded flanges to ensure stronger connections and simplify the installation of extra components, combining durability with practical convenience.

When working with liquid heating or cooling media, the half-pipe coil jacket generally provides better heat transfer performance. Its effective area is smaller, about one-third less than that of a conventional jacket, but the flow rate is two to three times higher. In half-pipe coil jackets, the faster flow helps avoid many of the problems seen in conventional designs, like uneven heat transfer or buildup inside the jacket. This way, the heat spreads more evenly, making the process both more efficient and steadier during operation.

The half-pipe coil jacket is recommended. Cooling water often contains ions such as H⁺ and Cl⁻ that can accelerate corrosion. In conventional jackets, deposits can accumulate and worsen this effect. The faster flow in half-pipe coil jackets minimizes deposits and reduces the risk of wall corrosion.

Yes. These glass lined reactors are CE-certified for the European Union, also comply with Japanese JIS standards, U.S. ASME codes, and Chinese JB standards. Backed by these certifications, they fully meet the compliance requirements for export to EU markets.
