Primary structural component of chemical storage tanks designed to safely contain and protect hazardous or corrosive substances under various pressure and temperature conditions.

技术定义与适配语境
典型 罐体/壳体 会按材料、尺寸公差、适配关系和失效风险在 化学制造 中评估。

The tank body or shell is the main cylindrical or spherical structural element of a chemical storage tank, engineered to withstand internal pressures, external loads, and environmental factors while preventing leaks and contamination. It serves as the primary barrier between stored chemicals and the external environment, requiring precise engineering for material compatibility, corrosion resistance, and structural integrity.

定义
The tank body or shell is the main cylindrical or spherical structural element of a chemical storage tank, engineered to withstand internal pressures, external loads, and environmental factors while preventing leaks and contamination. It serves as the primary barrier between stored chemicals and the external environment, requiring precise engineering for material compatibility, corrosion resistance, and structural integrity.
工作原理
Operates as a pressure-retaining boundary that contains chemical substances through balanced mechanical design. The shell distributes internal pressure stresses evenly across its surface area, utilizing principles of thin-walled pressure vessel theory (hoop stress and longitudinal stress calculations) to maintain structural stability while preventing deformation or rupture.
材料
Stainless steel (AISI 304/316/L)carbon steel with corrosion-resistant linings (epoxyrubberglass-flake)fiber-reinforced plastic (FRP)polyethylene (HDPE/XLPE)or specialized alloys (HastelloyInconel) depending on chemical compatibility requirements.
Capacity
1,000-100,000 liters
Diameter
1-10 meters
Wall Thickness
6-50 mm
Design Pressure
Atmospheric to 10 bar
Design Temperature
-40°C to 200°C
Corrosion Allowance
1-3 mm
标准
ISO 28300ASME BPVC Section VIIIDIN 28018EN 14015

常见问题

What factors determine material selection for chemical tank shells?

Material selection depends on chemical compatibility, temperature/pressure requirements, corrosion resistance needs, regulatory compliance, and total cost of ownership including maintenance.

How often should tank shells be inspected for integrity?

Regular visual inspections quarterly, comprehensive thickness testing annually, and full integrity assessment every 3-5 years depending on service conditions and stored chemicals.
