Press pad or chain, for a pipe press fitting, has adjacent press zones with different geometries to give a consistent distortion at the pipe ring seal chamber
The press pad or chain, for a hydraulic or mechanical press unit to press a pipe with a tubular press fitting, has two or more press components (3) to impose a pressed geometry. The press component has two longitudinal and adjacent press zones (10,11) with different out-of-round geometries and with rounded corners (13), and where one forms a ring bead, together with a further press zone (12).
