Jacket Shell is the outer containment structure in jacketed cooling/heating systems that creates an annular space for thermal fluid circulation around process vessels.
A Jacket Shell is a cylindrical or conical pressure vessel component designed to enclose another vessel (inner shell) while maintaining a precise annular gap. This gap forms a closed circuit for heating/cooling media (steam, water, thermal oil, or refrigerants) to transfer thermal energy through the inner vessel wall. It features inlet/outlet nozzles, baffles for optimized flow distribution, insulation attachments, and structural supports while maintaining pressure integrity and thermal efficiency.

不是客户评论，也不是实时热度。以下维度用于前期 RFQ 准备和供应商评估。
这些分值是采购评估维度示例，不代表真实客户评分、具体国家买家反馈或实时询盘。
Four primary types: Conventional (full vessel coverage), Dimpled (spot-welded plates for pressure distribution), Half-Pipe (welded pipe coils for high pressure), and Plate Coil (embossed plates for compact design).
Through baffle design for turbulent flow, optimal annular gap calculation (25-100mm), material selection for thermal conductivity, and surface finish to minimize fouling resistance.
Regular inspection for corrosion/erosion, pressure testing, thermal imaging for hot/cold spots, cleaning of internal surfaces, and gasket replacement at connections.
