技术定义与适配语境
典型 连接体/线轴 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 Connection Body/Spool is a critical piping component that forms part of an outlet connection assembly in industrial fluid systems. It serves as the structural interface between different piping sections or between piping and equipment, featuring precisely machined ends (flanged, threaded, or welded) to ensure leak-proof connections. This component maintains alignment, absorbs thermal expansion stresses, and provides access points for maintenance in complex piping networks.

定义
The Connection Body/Spool is a critical piping component that forms part of an outlet connection assembly in industrial fluid systems. It serves as the structural interface between different piping sections or between piping and equipment, featuring precisely machined ends (flanged, threaded, or welded) to ensure leak-proof connections. This component maintains alignment, absorbs thermal expansion stresses, and provides access points for maintenance in complex piping networks.
工作原理
The component functions by creating a sealed, pressure-resistant conduit between two connection points. Its precisely machined ends mate with corresponding fittings using gaskets and fasteners to form a leak-proof joint. The spool configuration allows for thermal expansion compensation and misalignment correction while maintaining structural integrity under operational pressures and temperatures.
材料
Typically manufactured from carbon steel (ASTM A106/A53)stainless steel (304/316L)alloy steelor specialized alloys depending on service conditions. Materials must meet pressuretemperatureand corrosion resistance requirements.
Surface Finish
Ra 3.2 μm or better
End Connections
Flanged, Threaded, Butt-Weld
Pressure Rating
150-2500 PSI
Temperature Range
-20°C to 400°C
Dimensional Standards
ASME B16.5, B16.9
标准
ISO 15649ASME B31.3DIN 2635

常见问题

What is the difference between a connection body and a spool?

A connection body typically refers to a shorter component with specific end connections, while a spool is a longer prefabricated piping section that may include multiple components welded together for installation efficiency.

How do I select the right material for a connection spool?

Material selection depends on fluid compatibility, pressure/temperature requirements, corrosion resistance needs, and industry standards. Common choices include carbon steel for general service, stainless steel for corrosive environments, and alloys for high-temperature applications.
