The range is manufactured with a flat face and does not feature the raised sealing face of heavy duty flanges such as ANSI B 16.5, BS4504 and DIN 2576 (PN 10 and 16) for example. Although the standard shows the flange with a raised boss on the rear, the flanges are usually supplied at flat plate flanges unless otherwise stated.
Originally designed for use in carbon steel, these flanges are manufactured from plate and bar and are available in mild steel, stainless steel and copper alloys. These flanges are often used in hygienic applications such as food and brewing where corrosion and cost are the main criteria.
