This tubing is designed to provide reliable solutions for industries that operate in tough, corrosive environments. With a strong commitment to quality, precision, and adherence to international standards, Samia Pipes delivers Monel 400 Tubing that shines in marine, chemical, oil & gas, and heat exchanger applications. Renowned for its remarkable resistance to seawater, acids, and alkalis, as well as its impressive mechanical strength, the tubing is produced using advanced facilities and rigorous quality control to ensure it meets the demanding performance needs of various industries.
Monel 400 Tubing is made up of about 63% nickel and 28–34% copper, along with small amounts of iron, manganese, carbon, and silicon. This solid-solution alloy isn’t hardenable through heat treatment, but it boasts excellent mechanical properties, including a tensile strength of up to 550 MPa and a yield strength of around 240 MPa, with an elongation of up to 35%. It retains toughness and ductility across a wide temperature range and shows exceptional resistance to seawater, hydrofluoric acid, alkalis, and stress-corrosion cracking. Its high strength and corrosion resistance make it perfect for demanding, high-pressure environments.
