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.
