It is not welded directly to the pipe, but slides over the stub end and can rotate freely, allowing easy installation and precise alignment of the bolt holes.<br \/>This design makes it particularly suitable for installations in confined spaces and for systems requiring frequent maintenance operations.<br \/>The flange itself does not provide sealing, which is instead ensured by the stub end surface, while the flange acts as the clamping element.<\/p>\n<p><strong>Characteristics of the lj flange (lap joint):<\/strong><\/p>\n<ul>\n<li>Use in combination with stub ends compliant with ASME standards;<\/li>\n<li>Easier alignment during installation;<\/li>\n<li>Available in various materials and ANSI pressure classes (150, 300, 600\u2026);<\/li>\n<li>Quick assembly thanks to the free rotation of the flange;<\/li>\n<li>No stress on the piping, ideal for sensitive materials or those difficult to weld;<\/li>\n<li>Easy maintenance; the flange can be removed without intervening on the line.<\/li>\n<\/ul>\n<p>[\/vc_column_text][\/vc_column_inner][\/vc_row_inner][vc_empty_space empty_h=&#8221;1&#8243;][vc_button button_color=&#8221;accent&#8221; border_width=&#8221;0&#8243;
