Versatile Face Types and Material Grades

Lap joint flanges come in multiple face types: Flat Face (FF), Raised Face (RF), and Ring Type Joint (RTJ), offering compatibility with diverse piping systems. Manufactured from stainless steel, carbon steel, alloy steel, and mild steel in grades such as ASTM A105, A182, and F53, these flanges are suited for rigorous industrial use.


Superior Corrosion Protection and Coatings

To safeguard lap joint flanges during transit and storage, various surface coatings are available, including electro-galvanized, hot dip galvanized, painted, and rust-proof oil finishes. These coatings help maintain product integrity and ensure longevity even in harsh corrosive environments.


Strict Compliance and Inspection Standards

Lap joint flanges are manufactured and tested to meet industry standards like ASME B16.5, DIN, JIS, BS, EN, GOST, and ISO. Each flange undergoes rigorous inspection, including hydrostatic testing when required, and is stamped with size, material, pressure rating, and heat number for full traceability.
