A Slip-On Flange is designed to slide directly over the pipe, making it a cost-effective solution prized for its ease of installation. It is secured with inside and outside welds, creating a strong, reliable connection without complex fitting. Typically made from carbon steel, stainless steel, and alloy steels, these flanges offer high corrosion resistance and are ideal for medium pressure and temperature systems. Their versatility makes them a popular choice for oil & gas, chemical processing, power generation, and water treatment, as well as for plumbing, HVAC, and other industrial piping to ensure a durable, leak-proof connection.
