These fittings are engineered to work in combination with <strong>Lap Joint Flanges<\/strong>, allowing easy alignment and disassembly of piping sections, especially where space constraints or corrosion-resistant materials are a concern. The <a href=\"https:\/\/www.primesteelcorp.com\/lap-joint-stub-end-asme-b16-9.html\">Lap Joint Stub End<\/a> acts as a welded extension of the pipe, while the backing flange remains loose, enabling cost-effective flange reuse and reducing material wastage in high-alloy systems. Ideal for <strong>low-pressure, non-critical<\/strong>, or <strong>frequently dismantled systems<\/strong>, they are widely used in <strong>chemical processing, water treatment, pharmaceuticals, oil &#038; gas<\/strong>, and <strong>marine applications<\/strong>. All our Lap Joint Stub Ends are manufactured according to <strong>ASME B16.9<\/strong> and <strong>MSS SP-43<\/strong> standards, with stringent dimensional accuracy and metallurgical integrity.<\/p>\n<hr \/>\n<h3>Features of Lap Joint Stub Ends:<\/h3>\n<ul>\n<li>Designed for use with <strong>Lap Joint (Loose) Flanges<\/strong><\/li>\n<li>Offers rotational alignment and ease of disassembly<\/li>\n<li>Reduces overall cost in high-alloy piping systems<\/li>\n<li>Minimizes corrosion in flange areas as only the stub end contacts the fluid<\/li>\n<\/ul>\n<hr \/>\n<h3>Dimensional Range \u2013 Lap Joint Stub End Specifications:<\/h3>\n<ul>\n<li><strong>Size Range:<\/strong> \u00bd\u201d NB to 24\u201d NB<\/li>\n<li><strong>Wall Thickness:<\/strong> SCH 10S to SCH XXS<\/li>\n<li><strong>Stub End Types:<\/strong>\n<ul>\n<li><strong>Type A<\/strong> \u2013 Suitable for standard lap joint flanges<\/li>\n<li><strong>Type B<\/strong> \u2013 Compatible with slip-on flanges<\/li>\n<\/ul>\n<\/li>\n<li><strong>Face Finish:<\/strong> Standard machined finish for sealing with gasket<\/li>\n<li><strong>Ends:<\/strong> Beveled ends as per ASME B16.25<\/li>\n<\/ul>\n<p>All sizes are available in <strong>Short Stub End<\/strong> and <strong>Long Stub End<\/strong> configurations.<\/p>\n<hr \/>\n<h3>Applicable Standards for Lap Joint Stub Ends:<\/h3>\n<ul>\n<li><strong>ASME B16.9<\/strong> \u2013 Factory-made wrought buttwelding fittings<\/li>\n<li><strong>MSS SP-43<\/strong> \u2013 Light-weight stub ends for corrosion-resistant applications<\/li>\n<li><strong>DIN \/ EN Norms<\/strong> \u2013 For custom projects upon request<\/li>\n<\/ul>\n<hr \/>\n<h3>Material Grades Available:<\/h3>\n<ul>\n<li><strong>Stainless Steel:<\/strong> A403 WP304, WP316, WP316L, WP321, WP904L<\/li>\n<li><strong>Carbon Steel:<\/strong> A234 WPB, WPC<\/li>\n<li><strong>Alloy Steel:<\/strong> A234 WP11, WP22, WP5<\/li>\n<li><strong>High Nickel Alloys:<\/strong> Inconel 600 \/ 625, Monel 400, Hastelloy C276, Alloy 20<\/li>\n<li><strong>Duplex &#038; Super Duplex:<\/strong> UNS S31803, S32750, S32760<\/li>\n<\/ul>\n<p>Each stub end is thoroughly tested for dimensional accuracy, pressure handling, and corrosion resistance.<\/p>\n<hr \/>\n<h3>Industries in Sri Lanka Using Lap Joint Stub Ends:<\/h3>\n<ul>\n<li><strong>Desalination &#038; Water Plants<\/strong> \u2013 Flanged joints for anti-corrosive pipelines<\/li>\n<li><strong>Pharmaceutical &#038; Food Industry<\/strong> \u2013 Sanitary systems that require regular cleaning<\/li>\n<li><strong>Petrochemical Facilities<\/strong> \u2013 Corrosion-prone areas in low-pressure systems<\/li>\n<li><strong>Offshore &#038; Marine Engineering<\/strong> \u2013 For easy maintenance of saltwater lines<\/li>\n<li><strong>Breweries &#038; Dairy Plants<\/strong> \u2013 For hygienic and non-contaminating installations<\/li>\n<\/ul>\n<hr \/>\n<p>\n<i class=\"fas fa-envelope\"><\/i> <strong>Need a quote or have a technical query?
