Monel 400 Pipes

What is Monel 400 Pipes ?

Monel 400 pipes are made from a strong nickel-copper alloy known for its resistance to corrosion and seawater. This B165 N04400 alloy contains around 67% nickel and 23% copper, along with iron and trace elements. Monel 400 works well in high temperatures—up to 1000°F—and has a density of 8.80 g/cm³ and a melting point between 2370°F and 2460°F. Parag Metals is a trusted monel 400 pipe suppliers, offering top-quality ERW, seamless, and welded pipes. We stock and deliver products built to perform in tough conditions.

Our Monel 400 pipes come in a size range of 4mm to 219mm, with thicknesses from 0.5mm to 20mm. Length options include single, double random, and custom-cut lengths. We offer different finishes such as bright, polished, and annealed. Shapes include round, square, rectangular, and hydraulic forms, allowing customers to choose the best fit for their projects. Every alloy 400 pipe and tubing meets dimensional accuracy and finishing standards.
