Jacket Body/Shell Component – Machinery and Equipment Manufacturing

Component Specifications

Definition

The Jacket Body/Shell is a critical pressure-retaining component in industrial cooling jackets, forming an annular space or channel around vessels, reactors, or machinery. It provides structural integrity while enabling controlled circulation of cooling fluids (water, glycol, or refrigerants) to absorb and transfer heat from the enclosed equipment. Engineered to withstand thermal expansion, pressure differentials, and corrosive environments, it ensures efficient heat exchange and process stability.

Working Principle

The Jacket Body/Shell operates on conductive and convective heat transfer principles. It creates a sealed enclosure around equipment surfaces, allowing coolant to flow through the annular space. Heat from the inner equipment wall transfers through the shell material to the circulating coolant, which carries thermal energy away. The design maximizes surface contact and flow dynamics to optimize cooling efficiency while maintaining structural stability under thermal and mechanical stresses.

Materials

Carbon steel (ASTM A516), stainless steel (304/316L), duplex stainless steel, nickel alloys, or corrosion-resistant alloys. Material selection depends on temperature range (-40°C to 300°C), pressure requirements (up to 10 bar standard), and chemical compatibility with coolants and process media.

Technical Parameters

Surface Finish Ra ≤ 3.2 μm for hygienic applications
Wall Thickness 3-12 mm depending on diameter and pressure
Pressure Rating Up to 10 bar (standard), custom designs up to 25 bar
Connection Types Flanged (ANSI/DIN), welded, or threaded
Temperature Range -40°C to 300°C

Standards

ISO 9001, ASME BPVC Section VIII, PED 2014/68/EU, DIN 28008
