定义
A flange ring is a critical component in pressure vessel manway assemblies, designed to create a robust, leak-proof interface between the removable manway cover and the vessel shell. It typically features bolt holes for fastening and a sealing surface to accommodate gaskets, ensuring pressure integrity and safety in high-pressure environments.
工作原理
The flange ring works by distributing clamping force evenly via bolts to compress a gasket against its sealing surface, forming a tight seal that prevents fluid or gas leakage under pressure. It aligns and secures the manway cover to the vessel, allowing for safe access while maintaining structural integrity.
材料
Common materials include carbon steel (e.g.ASTM A105)stainless steel (e.g.ASTM A182 F304/F316)or alloy steelselected based on pressuretemperatureand corrosion resistance requirements.
Diameter
Typically 300-600 mm
Thickness
10-25 mm
Surface Finish
Ra 3.2 μm or smoother for sealing
Pressure Rating
150-300 psi
Bolt Circle Diameter
As per ASME standards
标准
ASME BPVC Section VIIIISO 7005-1DIN 2501
