组件规格

定义
A critical fluid transfer component designed to create a secure, leak-proof connection between external gas supply lines and the inlet manifold of processing equipment. It ensures controlled gas flow entry while maintaining system pressure integrity and preventing contamination.
工作原理
Operates by providing a sealed interface between the gas supply line and manifold inlet. The fitting's internal geometry directs gas flow into the manifold chamber while maintaining pressure through precision threading, gaskets, or compression mechanisms that prevent leaks.
材料
Stainless steel (AISI 316L/304)brass (C36000)aluminum alloys (6061-T6)or engineered plastics (PTFEPEEK) depending on gas compatibilitypressure requirements (typically 0-1000 psi)and temperature range (-40°C to 200°C).
Leak Rate
<1×10⁻⁹ mbar·L/s helium
Port Size
1/4" to 2" standard
Surface Finish
Ra ≤ 0.8 μm for sealing surfaces
Connection Type
NPT, BSPP, SAE, or flange
Pressure Rating
Up to 1000 psi
Temperature Range
-40°C to 200°C
标准
ISO 1179DIN 3852ASME B1.20.1

常见问题

What factors determine material selection for inlet port fittings?

Material selection depends on gas chemical compatibility (corrosion resistance), operating pressure/temperature, regulatory requirements (FDA/USP Class VI for food/pharma), and cost. Stainless steel offers broad chemical resistance, while plastics provide cost savings for non-critical applications.

How often should inlet port fittings be inspected?

Visual inspection monthly for leaks/corrosion, torque verification quarterly, and replacement per manufacturer schedule (typically 2-5 years) or when leak tests exceed 1×10⁻⁹ mbar·L/s. High-cycle systems require more frequent checks.
