定义
The shell or casing in a heat transfer assembly is a structural component designed to enclose and protect internal heat exchange elements such as tubes, plates, or coils. It maintains pressure integrity, directs fluid flow, provides thermal insulation, and prevents external contamination while withstanding operational stresses including thermal expansion, pressure differentials, and mechanical loads.
工作原理
Acts as a pressure vessel and thermal barrier, containing heat transfer fluids and maintaining optimal temperature gradients by minimizing heat loss to the environment through insulation and structural design.
材料
Carbon steel (ASTM A516)stainless steel (AISI 304/316)aluminum alloys (6061-T6)or composite materials with corrosion-resistant coatingsselected based on temperature range (-50°C to 500°C)pressure (up to 30 bar)and fluid compatibility.
Surface Finish
Ra ≤ 3.2 μm
Wall Thickness
5-20 mm
Insulation Type
Mineral wool or ceramic fiber
Pressure Rating
Up to 30 bar
Temperature Range
-50°C to 500°C
Connection Standards
ANSI/ASME flanges
标准
ISO 9001ASME BPVC Section VIIIDIN EN 13445

常见问题

What factors determine shell material selection?

Material selection depends on operating temperature, pressure, fluid corrosivity, thermal conductivity requirements, and cost considerations, with stainless steel preferred for corrosive environments and carbon steel for high-pressure applications.

How does shell design affect heat transfer efficiency?

Proper shell design minimizes heat loss through insulation, optimizes fluid flow distribution to prevent hotspots, and accommodates thermal expansion to maintain structural integrity under thermal cycling.
