Slip On Flanges
Slip On Flanges are widely used pipe flanges designed to slide over pipes and provide strong welded connections with easy installation. Manufactured from premium quality materials, they offer excellent durability, corrosion resistance, pressure handling capability, and reliable performance for oil & gas, petrochemical, chemical processing, power plants, marine, and industrial piping applications.
Overview
Slip On Flanges are one of the most commonly used flange types designed to fit over the outside diameter of pipes before being welded into position. Their simple design allows quick installation, accurate alignment, and cost-effective piping connections.
These flanges are secured using internal and external fillet welds, providing good mechanical strength and dependable sealing performance. Slip On Flanges are commonly preferred for low to medium-pressure applications where easy assembly and maintenance are required.
Veltronova Industries supplies premium quality Slip On Flanges manufactured with advanced technology and high-grade materials. Available in various sizes, pressure ratings, face types, and material grades, our Slip On Flanges are suitable for refineries, oil & gas industries, petrochemical plants, chemical processing, power generation, marine, and industrial piping systems.
