Monel 400 Pipes

ASTM B165 UNS N04400 Seamless Monel Pipes & ASTM B725 Welded Pipes Supplier in India


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.


Monel 400 Pipes

Alloy 400 seamless pipe is available in sizes from 4mm to 219mm with thickness ranging from 0.5mm to 20mm, offered in single, double random, or custom cut lengths. Monel 400 welded pipe sizes range from 5.0mm to 1219.2mm, with identical thickness and length options. Both types are offered with bright, polished or annealed finishes to meet functional and aesthetic requirements. UNS N04400 pipe is made with modern procedures to assure dimensional precision and constant performance.


Every UNS N04400 Monel 400 pipe goes through quality checks, including non-destructive, PMI, mechanical, destructive, NABL-approved lab, and flaring tests to verify strength and material integrity. Pipes are packed in wooden boxes, bubble wraps, or steel strip bundles, with customized options to protect the product during transit. Our monel 400 pipe price reflects the quality, precision, and durability.
