Nickel-based alloy lap joint stub end
Nickel-based alloy lap joint stub ends are a type of special lap joint flange pipe fitting, formed from nickel-based alloy pipe blanks or plates, with one end being a butt-weld bevel for fusion welding to pipe of the same material, and the other end being solution-treated and finish-turned to form a flat lap joint surface, which can be rotationally aligned with a backing flange. We routinely stock Hastelloy, Monel, Inconel, and Incoloy series materials, covering both LP long-type and SP short-type configurations, with manufacturing referencing standards such as GB/T12459, ASME B16.9, MSS SP43, and ASTM SB366. The products are used in highly corrosive, ultra-high-temperature, high-purity sterile, or high-radiation pipelines where stainless steel, duplex steel, and alloy steel cannot perform, helping to solve problems of misalignment during joining, high-temperature deformation, and maintenance in confined spaces. For specific diameters, materials, pressure ratings, and delivery lead times, please contact us to confirm.
