Cylindrical Semi-circular Coil

The cylindrical semi-circular heat exchange tube is a common heat transfer enhancement structure, typically uniformly welded around the outer wall of the container. It facilitates heat exchange between the introduced heat transfer medium and the internal materials through internal flow, enabling temperature control during reaction or storage processes. Compared to traditional jacketed heat exchangers, this design offers higher heat transfer coefficients, faster media flow rates, and a more compact overall configuration, making it widely used in stirred reactors and storage tanks requiring temperature-controlled materials. The welding quality between the semi-circular tubes and the cylinder directly impacts equipment safety; therefore, welding deformation must be controlled to prevent uneven stress distribution on the cylinder, while ensuring no media leakage at joint interfaces. Both design and manufacturing phases must comply with relevant pressure vessel specifications.
