支撑裙座/支腿

Structural support system for evaporator vessels providing stability, load distribution, and thermal expansion accommodation.

技术定义与适配语境
典型 支撑裙座/支腿 会按材料、尺寸公差、适配关系和失效风险在 机械和设备制造 中评估。

The Support Skirt/Legs are critical structural components designed to securely mount an evaporator body/vessel to its foundation while supporting the vessel's weight, operational loads, and contents. They provide mechanical stability, distribute loads evenly to prevent stress concentrations, and accommodate thermal expansion/contraction during heating/cooling cycles. These components typically consist of cylindrical skirts or multiple legs attached to the vessel shell with reinforcing plates and anchor bolt arrangements.

定义
The Support Skirt/Legs are critical structural components designed to securely mount an evaporator body/vessel to its foundation while supporting the vessel's weight, operational loads, and contents. They provide mechanical stability, distribute loads evenly to prevent stress concentrations, and accommodate thermal expansion/contraction during heating/cooling cycles. These components typically consist of cylindrical skirts or multiple legs attached to the vessel shell with reinforcing plates and anchor bolt arrangements.
工作原理
The support system transfers vertical loads (dead weight, contents) and lateral loads (wind, seismic) from the evaporator vessel to the foundation through structural members. Skirts provide continuous support around the circumference with stress distribution, while legs create discrete support points. Both designs incorporate thermal expansion joints or sliding plates to allow movement during temperature changes without causing structural damage.

常见问题

What is the difference between support skirt and support legs for evaporators?

Support skirts are continuous cylindrical structures providing 360-degree support with better stress distribution, while legs are discrete columns offering easier access for maintenance and inspection. Skirts are preferred for tall vessels with high bending moments, while legs are common for smaller vessels.

How do support skirts accommodate thermal expansion?

Support skirts incorporate expansion joints, sliding plates, or flexible connections at the base to allow vertical and radial movement during temperature changes. This prevents thermal stress buildup that could damage the vessel or foundation.
