定义
A connection flange is a precision-engineered mechanical component designed to create a secure, leak-proof joint between an outlet nozzle/port and a valve in industrial fluid handling systems. It features bolt holes, sealing surfaces, and standardized dimensions to ensure proper alignment, pressure containment, and easy maintenance access.
工作原理
The flange creates a mechanical connection by clamping two mating surfaces together with bolts, compressing a gasket between them to form a pressure-tight seal. It transfers mechanical loads while allowing controlled fluid flow between the nozzle and valve.
材料
Carbon steel (ASTM A105)stainless steel (AISI 304/316)alloy steelor ductile iron with corrosion-resistant coatings where required.
Face Type
Raised face (RF), flat face (FF), ring-type joint (RTJ)
Surface Finish
125-250 µin Ra for sealing surfaces
Pressure Rating
150-2500 PSI
Temperature Range
-20°C to 400°C
Bolt Hole Quantity
4, 8, 12, or 16 holes
Bolt Circle Diameter
Standardized per ASME B16.5
标准
ASME B16.5ISO 7005-1DIN 2501EN 1092-1

常见问题

What is the difference between raised face and flat face flanges?

Raised face flanges have a small raised section around the bore for gasket compression, while flat face flanges have full contact surfaces. RF is standard for higher pressure applications.

How do I select the correct flange material for corrosive fluids?

Select stainless steel (316 for chlorides) or apply protective coatings. Consider fluid chemistry, temperature, and pressure when specifying materials.
