Crafting precision and durability within industrial infrastructures, Multi Metals is a premier manufacturer, supplier, and exporter of High Nickel Alloy Pipes and tubes. Our products hold approval from industry giants like Saudi Aramco, BHEL, GAIL, Hind Zinc, and NALCO, testifying to their superior quality and reliability.

At Multi Metals, versatility is our hallmark. We engineer these high nickel alloy pipes and tubes in various sizes, grades, specifications, and types, ensuring a seamless fit for varied industrial needs. Ranging from 1/2″NB TO 150 “NB IN, our Monel 400 Pipes and tubes are available in multiple configurations such as round, square, rectangular, and hydraulic forms.

Dedicated to meeting precise requirements, our pipes & tubes feature diverse ends—plain, threaded, and beveled—and are produced in different types: welded with seamless, ERW (Electrical Resistance Welding), welded fabricated. These products, which include chromium, molybdenum, tungsten, titanium, and other alloying elements, are provided with unprecedented heat resistance characteristics accompanied by high similar to austenitic steels.

Nickel 200 Seamless Pipes represent the pinnacle of engineering innovations, providing superior high-temperature resistance, corrosion protection strength, and toughness that are ideal for even the most challenging uses. On the other hand, with our range of Inconel

The corrosion resistance of our Inconel 625 Seamless Pipes is exceptional due to their lofty position in the galvanic electrochemical sequence of metals. Also, Incoloy 800 Welded Tubes made from corrosion-resistant nickel alloys are equally good in resisting acids such as sulphuric acid, hydrochloric acid and phosphoric acid neutral solutions.

Thus, SMO, a highly alloyed stainless steel of the austenitic type with increased chemical resistivity, fits in an aggressive chloride-bearing medium. It provides excellent resistance to pitting, crevice corrosion, stress corrosion cracking, and significantly more strength than regular austenitic stainless steel.

Hastelloy C22 Pipes and Tubes exhibit applicability in weld heat-affected zones, making them ideal for diverse chemical process applications. Similarly, while Hastelloy C276 Pipes and tubes tend to toughen during work, they remain easily formable, ensuring quality outcomes.
Quality Assurance and Customer Satisfaction

Customer satisfaction remains our paramount objective. To uphold the highest standards, our products undergo rigorous testing—mill tests, 100% radiography, raw material assessment, hardness tests, macro/micro tests, flaring tests, intergranular corrosion checks, chemical analyses, third-party inspections, and PMI testing. These extensive examinations guarantee error-free products.

To cater to diverse client needs, our High Nickel Alloy Pipes and tubes, approved by esteemed organizations like Saudi Aramco, BHEL, GAIL, Hind Zinc, and NALCO, are available in custom ranges at competitive prices across various countries.
At Multi Metals, our commitment to excellence, precision engineering, and customer-centricity is reflected in every product, ensuring superior quality and performance for industrial infrastructures globally.
