Slip-on flanges are a common type of flange where the pipe is directly inserted into the flange bore and then connected by fillet welding. Due to their simple installation and relatively low requirements for pipe concentricity, they are widely used in various industrial piping systems. These flanges are commonly used in the petroleum, chemical, power, water supply and drainage, shipbuilding, and general industrial sectors, and are suitable for medium-low pressure and normal or medium temperature conditions.
- Materia: ASTM / ASME A/SA 105 ASTM / ASME A 350 , ASTM A 181 LF 2 / A516 Gr.70 A36, A694 F42, F46, F52, F60, F65, F706
- Size: 1/2″ (15 NB) to 48″ (1200NB)
- Flange Face Type : Flate Face (FF), Raised Face (RF), Ring Type Joint (RTJ)
Introduction
Slip-on flanges are typically manufactured from carbon steel, stainless steel, or alloy steel, and feature a simple structure, cost-effectiveness, and ease of welding and installation. Products can be manufactured according to international and industry standards such as ANSI, ASME, DIN, EN, and GB, and can be used with various gaskets to ensure good sealing performance and system reliability.
