Stainless Steel Lap Joint Flanges are specialized pipe fittings that pair with a stub end to create a flange connection. They are widely used in systems requiring frequent disassembly, alignment flexibility, or where pipes and components must be replaced often — such as in sanitary, chemical, and food processing industries.
Stainless Steel Lap Joint Flanges
Core Functions
-
Provides a removable flange connection for piping systems
-
Allows easy alignment and assembly/disassembly
-
Facilitates maintenance, inspection, and cleaning
Key Features
-
Material: High-grade stainless steel (commonly 304, 316, or 316L) for excellent corrosion resistance and durability
-
Design:
-
Twin component system: Uses a lap joint flange + stub end
-
Pipe is welded to the stub end; the lap joint flange slides over and is bolted to the mating flange
-
-
Alignment Flexibility: Flange can rotate freely around the stub end, making alignment easier during installation
-
Standards Compliance: Manufactured to ASTM/ASME, DIN, EN, JIS, and other international standards
-
Pressure Ratings: Available in standard classes (e.g., 150 #, 300 #, 600 #) depending on application and design code
-
Surface Finish: Smooth flange face for effective sealing with gaskets
