Nickel Alloy Welded Pipe & Tube<\/h1>\n \n

\n When industrial projects require large-diameter fluid transport, extensive exhaust ducting, or cost-effective heat exchange solutions, welded tubulars are the premier choice. 28Nickel manufactures high-quality welded nickel alloy pipes and tubes from premium rolled plate and strip. Subjected to 100% radiography (X-Ray) and severe quality control, our welded products ensure the weld seam performs with the exact same corrosion resistance and mechanical strength as the base superalloy.\n <\/p>\n <\/div>\n\n

Available Alloy Grades for Welded Pipe & Tube<\/h2>\n

\n We manufacture welded piping systems to handle everything from aggressive seawater in desalination plants to highly acidic flue gases in power generation scrubbers.\n <\/p>\n \n

Engineering Advantages of Welded Construction<\/h2>\n

\n Advanced continuous welding technologies (such as GTAW\/TIG and Plasma) combined with post-weld heat treatment have made welded \u043d\u0438\u043a\u0435\u043b\u0435\u0432\u044b\u0435 \u0441\u043f\u043b\u0430\u0432\u044b<\/a> a highly reliable alternative to seamless pipes.\n <\/p>\n \n

\n \n
\n
\n
\u2b55<\/div>\n

Unlimited Large Diameters<\/h3>\n <\/div>\n

While seamless pipes are limited by extrusion press capacities (typically topping out around 24 inches), welded pipes can be rolled and fabricated to virtually any diameter, making them essential for large chemical mains and exhaust ducting.<\/p>\n <\/div>\n\n

\n
\n
\ud83d\udcc9<\/div>\n

Cost & Lead Time Efficiency<\/h3>\n <\/div>\n

Forming pipe from readily available flat-rolled plate or coil is significantly faster and more economical than piercing solid billets. This provides major cost savings for large-scale infrastructure projects requiring miles of piping.<\/p>\n <\/div>\n\n

\n
\n
\ud83d\udd0d<\/div>\n

100% Weld Integrity<\/h3>\n <\/div>\n

Our welded pipes undergo strict Non-Destructive Testing (NDT), including 100% X-Ray Radiography and Hydrostatic testing. The weld bead is often cold-worked and fully solution-annealed to perfectly blend its metallurgical structure with the parent metal.<\/p>\n <\/div>\n\n

\n
\n
\ud83d\udccf<\/div>\n

Superior Concentricity<\/h3>\n <\/div>\n

Because they are formed from flat sheets with highly uniform thickness, welded pipes generally exhibit better concentricity and more consistent wall thickness (WT) than seamless pipes, which can suffer from slight eccentricity during extrusion.<\/p>\n <\/div>\n\n <\/div>\n\n

\n
\n
\ud83c\udf0a<\/div>\n

Marine & Desalination<\/h3>\n <\/div>\n

Long runs of welded Monel 400 piping are heavily utilized in seawater intake lines, brine heaters, and offshore platform fire water systems due to their exceptional resistance to chloride pitting.<\/p>\n <\/div>\n\n

100% Weld Integrity<\\\/h3>\\n <\\\/div>\\n

Our welded pipes undergo strict Non-Destructive Testing (NDT), including 100% X-Ray Radiography and Hydrostatic testing. The weld bead is often cold-worked and fully solution-annealed to perfectly blend its metallurgical structure with the parent metal.<\\\/p>\\n <\\\/div>\\n\\n

Superior Concentricity<\\\/h3>\\n <\\\/div>\\n

Because they are formed from flat sheets with highly uniform thickness, welded pipes generally exhibit better concentricity and more consistent wall thickness (WT) than seamless pipes, which can suffer from slight eccentricity during extrusion.<\\\/p>\\n <\\\/div>\\n\\n <\\\/div>\\n\\n

FGD & Scrubber Piping<\\\/h3>\\n <\\\/div>\\n

Large diameter welded pipes made from alloys like Hastelloy C-276 and Inconel 625 are the backbone of Flue Gas Desulfurization (FGD) systems, handling highly acidic and abrasive slurry.<\\\/p>\\n <\\\/div>\\n\\n

Marine & Desalination<\\\/h3>\\n <\\\/div>\\n

Long runs of welded Monel 400 piping are heavily utilized in seawater intake lines, brine heaters, and offshore platform fire water systems due to their exceptional resistance to chloride pitting.<\\\/p>\\n <\\\/div>\\n\\n
