Sumer Metal Industries Private Limited is a trusted manufacturer, supplier and exporter of Inconel 718 Clad Tubes, offering premium nickel-base clad tubing engineered for extreme environments. Using controlled cladding processes and precision finishing, Sumer Metal produces clad tubes that combine the corrosion and high-temperature resistance of Inconel 718 with ductile backing materials to meet long service life requirements in oil & gas, petrochemical, power generation and aerospace applications.
Our Inconel 718 cladding is deposited/formed to exact metallurgical and dimensional tolerances to ensure a sound metallurgical bond, consistent thickness and minimal dilution. Tubes are produced in a variety of product forms — welded, seamless and clad — and undergo full inspection and NDT (visual, dimensional, UT/eddy current where requested) before dispatch. Sumer Metal’s quality systems and traceability ensure each tube is supplied with heat-treatment and test certificates per customer and international standards.
Typical end-uses for our Inconel 718 clad tubes include high-pressure heat exchangers, downhole tubular components, high-temperature process piping, gas turbine components, and corrosion-resistant cladded liners for reactors and piping. The alloy’s excellent creep and tensile strength at elevated temperatures, together with weldability and age-hardening response, makes it a go-to choice where a corrosion-resistant surface layer over a lower-cost structural core is required.
We supply standard and custom sizes, wall thicknesses and clad thickness options with relevant heat treatment (solution + precipitation age) tailored to the application. Complementary services include bespoke cutting, end-machining, non-destructive testing, and supply of Mill Test Certificates (MTC) per EN/ASTM/ASME specifications. Our technical team can assist in material selection, specifying clad thickness and advising on welding and joining practices for field installation.

Inconel 718's nickel-chromium matrix, strengthened with niobium and titanium precipitates, retains high tensile and creep strength at elevated temperatures and resists oxidation and chloride corrosion. Cladding provides a corrosion-resistant surface over a structural core for longer service life.
Yes — Sumer Metal provides full Mill Test Certificates (MTC), heat treatment records and NDT reports. We regularly export to Oman, Qatar, Saudi Arabia, UAE, Kuwait, Spain, Germany, USA, Canada and regions across Africa.
Clad thickness depends on corrosion severity, temperature and expected service life—typical ranges are 0.5–6 mm. Backing material is selected for mechanical load, cost and weldability (carbon steel, low alloy or stainless). Contact our technical team for application-specific advice.
