<p>\r\n    SUNHY supplies <strong>butt weld stub ends<\/strong> (also known as <strong>lap joint stub ends<\/strong>) designed for\r\n    lap joint flange assemblies.

ends clean and dry.<\/li>\r\n    <li><strong>Fit-up &amp; tack<\/strong> \u2014 Align centerlines, control root gap, tack evenly to reduce distortion.<\/li>\r\n    <li><strong>Weld per qualified WPS<\/strong> \u2014 Follow project welding procedure and heat input requirements (especially for stainless service).<\/li>\r\n    <li><strong>Assemble the flange joint<\/strong> \u2014 Position

specified; complete documentation for handover if required.<\/li>\r\n  <\/ol>\r\n\r\n  <p>\r\n    Tip: If the system requires frequent disassembly, keep gasket selection and bolt torque procedures
