Monel 400 pipe is a high-strength, corrosion-resistant alloy pipe made from a nickel-copper base with small amounts of carbon, aluminum, manganese, silicon, iron and sulfur. It provides outstanding mechanical strength with a yield strength of 35,000 psi and a tensile strength of 80,000 psi while remaining ductile. Monel 400 pipe is known for its resilience to seawater and strong chemicals, making it popular in demanding situations. Preston Pipes & Alloys is a leading monel 400 pipe supplier, providing precision-engineered products that meet quality standards. Because of its balanced composition, this pipe performs well in both oxidizing and reducing conditions making it a dependable choice for multiple industries.
Monel 400 seamless pipe and monel 400 welded pipe have various advantages based on the application. The seamless type ensure greater strength and consistency, while the welded type is more cost effective and available in bigger quantities. Both handle high temperatures up to 1000°F and have a density of 8.80 g/cm³. Their corrosion resistance to hydrochloric and hydrofluoric acids in deaerated environments makes them suitable for naval fittings, chemical processing equipment, pump shafts, propeller shafts, valves and pumps. The material's endurance in non-oxidizing chloride-based fluids increases its potential for offshore and chemical plant applications.
Preston Alloys ships alloy 400 pipes in seamless and welded forms. Monel 400 seamless pipes run from 4 mm to 219mm in outer diameter, with wall thickness from 0.5mm to 20mm, cut to single random, double random, or custom lengths. Welded pipes scale from 5.0mm to 1219.2mm with the same thickness and length options. Every pipe is bright, polished, or annealed, depending on the application. As a monel 400 pipes manufacturer, we hold tight tolerances across every batch of UNS N04400 pipe.
Testing runs before shipment: non-destructive checks, PMI, mechanical and destructive testing, flaring tests, and NABL-approved lab analysis. We pack pipes in wooden boxes, bubble wrap, or steel strip bundles, with custom packing on request. Our monel 400 pipe price reflects the testing and finish quality behind each order.
