组件规格

定义
A specialized threaded or flanged connection point on an inert gas supply manifold designed to securely mount a pressure gauge, allowing real-time monitoring of gas pressure within the system to ensure safe and efficient operation.
工作原理
Provides a sealed interface between the manifold's internal gas flow and the pressure gauge. The port transmits pressure from the gas stream to the gauge's sensing element (typically a Bourdon tube, diaphragm, or capsule), which converts pressure into mechanical movement displayed on the gauge dial.
材料
Stainless steel (AISI 316L/304)brass (C36000)or carbon steel with corrosion-resistant coatingscompatible with inert gases like nitrogenargonor helium.
Port Size
1/4" to 1/2" NPT common
Thread Type
NPT, BSP, or metric threads (e.g., G1/4, M20x1.5)
Sealing Method
O-ring, gasket, or thread sealant
Pressure Rating
Up to 3000 psi (207 bar)
Temperature Range
-20°C to 150°C
Connection Orientation
Vertical, horizontal, or angled
标准
ISO 1179DIN 3852ASME B1.20.1

常见问题

What is the purpose of a pressure gauge port on an inert gas manifold?

It allows installation of a pressure gauge to monitor real-time gas pressure, ensuring system safety, leak detection, and optimal performance in applications like welding, food packaging, or chemical processing.

How do I select the right pressure gauge port?

Consider gas compatibility, pressure/temperature ratings, thread type (NPT/BSP), material (stainless steel for corrosive environments), and compliance with industry standards like ISO or DIN.
