Chemical Reactor: Half Pipe Coil Jacket Design | JCT Machinery

The commonly used media in the reactor jackets include steam, heat conduction oil, cooling water, vacuum and thermal insulation media.

The purpose of using a cover is generally heating or cooling container and its internal medium, which can also be used as a sealing thermal insulation room for container.

1. Half Pipe Coil Jacket Design

Ⅰ. The half pipe of the cylinder uses the plate to suppress the forming.

Ⅱ. The half pipe and the cylinder welding open the inner slope, the root is welded, and the root gap is 2~3 mm during welding. If the outer slope is welded, the inner wall of the jacket is prone to tumor.

Ⅲ. After the overall production of the equipment is completed, the container is filled and pressed, and the coats test pressure to observe the weld and weld in the inner wall of the container.

For the reactor, the difficulty is half pipe coil jacket design structure. Becausee the device needs to be arranged with attachments such as branches, pipe mouths, etc., it is especially important to avoid interference with these accessories.

2. Characteristics of Half Pipe Coil Jacket Design

Ⅰ. Because the design of inner tube and the lower seal does not consider the impact of the external pressure, it can greatly reduce the computing thickness of the inner and sealed heads and save costs for equipment with a large diameter and higher coat pressure.

Ⅱ. You need to pay special attention to half pipe coli jacket design structure, because the inner tube needs to weld the entire half pipe, the welding deformation is large, and the selection requirements of the mixer need to be considered. The thickness of the inner tube needs to consider a certain stiffness. For example, the scratch film evaporator has high requirements for the oval degree of the cylinder, so it is necessary to consider the cost.
