Slip-On Flange

Slip-On Flange

Reliable and Economical Solutions for General Piping Applications

Our Slip-On Flanges are among the most widely used flange types in industrial piping, offering a perfect balance of performance, ease of installation, and cost-efficiency. Designed to slide over the pipe and be fillet welded on both the hub and bore, these flanges provide strong, leak-resistant connections for a wide range of low to medium-pressure systems.

Key Features & Benefits

• Easy Alignment and Installation: The slip-on design allows for simple positioning on the pipe, making alignment quick and hassle-free during welding.

• Lower Material and Fabrication Costs: Requires less material than weld neck flanges and involves simpler welding procedures, reducing overall project expenses.

• Versatile Application: Suitable for a broad spectrum of industries, including water treatment, HVAC, oil & gas, and general industrial piping.

• Strong and Durable Connection: Double fillet weld (inside and outside) ensures excellent structural integrity and resistance to leakage under moderate pressure.

• Wide Size and Pressure Availability: Offered in a comprehensive range of sizes and pressure classes to meet diverse system requirements.

Technical Specifications

• Size Range: 1/2" to 24" (DN15 to DN600)

• Pressure Classes: Class 150, 300, 600, 900, 1500, 2500

• Standards Compliance: ASME B16.5, ASME B16.47 Series A & B, EN 1092-1, BS 4504, DIN 2576

• Facing Types: Raised Face (RF), Flat Face (FF), Ring Type Joint (RTJ)
