Our Monel 400 Multilayer Tube is crafted from a nickel-copper alloy, blending about 67% nickel with 23% copper, plus small amounts of iron and manganese for added strength and corrosion resistance. This alloy is a workhorse, offering excellent resistance to sour gas, seawater, and acids. The multilayer design enhances its durability and pressure resistance, making it ideal for high-pressure oil and gas pipelines where standard tubing might fail.

This tubing thrives in harsh environments. It performs reliably at temperatures up to 1000°F (538°C), resists pitting and crevice corrosion, and stays non-magnetic, which is critical for sensitive equipment like sensors. We offer full customization—diameters, wall thicknesses, layer configurations, and finishes—so you get tubing that fits your pipeline system perfectly, whether it’s for an offshore rig or a refinery.
