This document provides information on circular flange pipe connections: - Circular flange AF connections have an extendable border that clamps onto pipes to seal them. A hollow profile stabilizes the pipe flange and stiffens the pipe. When correctly mounted and assembled, the connection can achieve an EUROVENT Class C rating. - The connection is suitable for pipe diameters between 200-3000mm. Special sizes are available on request, and stainless steel options are available on request. - Tables provide the product codes, materials, dimensions, pipe diameters, packaging quantities, and weights for various flange connection sizes. - Workmanship involves checking the pipe's internal diameter, pressing the flange onto the
