SO Flange (Slip-On Flange) is one of the most widely used pipe connection components in industrial piping systems. Designed for easy installation and reliable sealing, slip-on flanges are suitable for pipelines that operate under low to medium pressure and are widely applied in industries such as oil & gas, chemical processing, water supply, and shipbuilding.
Easy Installation – Pipes can be inserted directly into the flange bore before welding.
Cost-Effective – Lower material and fabrication costs compared to welding neck flanges.
Versatile Applications – Suitable for low- and medium-pressure piping systems.
Reliable Connection – Provides strong sealing when welded on both sides.
SO flanges are commonly used in:
Oil and gas transmission pipelines
Chemical and petrochemical plants
Water supply and treatment systems
Shipbuilding and mechanical engineering
