Overview
Half piper jacket mixing tank is generally used for high-temperature applications. The piping sits on the outside of the tank and allows for temperature controlling fluid or gas to flow around the contents of the tank without directly interacting with it such as cooling ,Steam,oil.
1:Technical Specifications of Half-Pipe Jacketed Agitated Vessel
Core Structural Features
2:Jacket Design
Utilizes semi-circular cross-section pipes (half-pipe) welded spirally or circumferentially to the vessel exterior, forming an efficient heat exchange channel with superior pressure resistance compared to conventional full jackets.
Typical pipe diameter: 50–200 mm, pitch spacing: 30–50 mm. The narrow flow path increases medium velocity to 3–5 m/s, enhancing turbulent heat transfer.
3:Agitator System
Equipped with paddle, anchor, or helical ribbon impellers, adjustable speed 0–1440 rpm, motor power 0.18–75 kW for uniform mixing and mass transfer optimization.
Optional baffles or mesh demisters can be added to improve fluid dynamics and prevent foam accumulation.
4:Technical Advantages
High-Efficiency Heat Transfer: Reduces medium consumption by >40% compared to full jackets, with 30% higher heat exchange efficiency.
Structural Strength: Half-pipe welding reinforces vessel rigidity, allowing thinner wall designs for cost savings.
Process Adaptability: Supports multi-inlet/outlet segmented circulation for precise temperature control (-20°C to 200°C).
5:Key Manufacturing Processes
Welding Standards
Laser welding with internal bevel, 2–3 mm root gap to avoid internal weld protrusions.
Hydrostatic testing sequence: jacket first, then vessel, ensuring weld integrity.
Forming Technology
Cylindrical half-pipes: Roll-formed from metal strips with springback compensation.
Head half-pipes: Split from seamless steel tubes, requiring precision cutting.
Assembly: Temporary supports maintain cylindrical roundness during welding to prevent ovality deviations.
Typical Applications
Pharmaceuticals: GMP-compliant reactors for high-viscosity slurries and temperature-sensitive reactions.
Food Processing: Sanitary mixing tanks for dairy/beverage production.
Chemical Industry: High-pressure reactors (2–10 bar), e.g., polymerization/catalytic processes.
Selection Guidelines
Impeller type vs. viscosity (anchor for high viscosity, turbine for gas-liquid dispersion).
Half-pipe layout to avoid interference with supports/nozzles.
For customized solutions, consult with engineers to optimize material (SS316L/2205), pressure rating, and sealing (mechanical/PTFE).
