Slip-On Flange (SORF/SOFF)

Slip On Flanges are versatile, easy‑to‑install flanges designed for low‑ and medium‑pressure pipelines. Manufactured in carbon steel, stainless steel, and alloy steel, they provide reliable sealing and alignment for water, oil & gas, HVAC, and industrial applications.

Slip On Flanges supplied by Anchor Building Materials Trading LLC are designed for secure, cost‑effective pipeline connections across a wide range of industrial systems. Featuring a slightly larger bore than the pipe, these flanges allow the pipe to slip through before welding, ensuring easy alignment and simplified installation.

Manufactured according to ANSI/ASME B16.5, B16.47, DIN, and API standards, Slip On Flanges are widely used in water supply networks, oil & gas pipelines, HVAC systems, fire‑fighting lines, chemical processing plants, and general industrial piping. Their robust construction, precision machining, and corrosion‑resistant materials ensure long‑term performance in demanding UAE operating conditions.

Slip On Flanges are available in raised face (RF), flat face (FF), and ring‑type joint (RTJ) configurations, making them suitable for various pressure classes and pipeline designs.
