Metalloy International is a remarkable fabricator of 317L Stainless Steel Heat Exchanger Tubes that are used in a number of sectors for cooling, boiling, and re-heating oils, fuels, and air, including fabrication of shell and tube heat exchangers, oil processing facilities, and petroleum products. Tubes made of 317L stainless steel can be ordered as seamless, welded, or welded redrawn. We still produce these Stainless Steel 317L Tubes with a blend of low-carbon, higher Molybdenum austenitic stainless steels with a higher Nickel alloy content to keep the price stable. As a result, the combination of these components has outstanding oxidation resistance as well as superior mechanical and fabricability characteristics.

It is an austenitic stainless steel with a higher concentration of chromium, nickel, and molybdenum, which has outstanding corrosion resistance. It is more immune to the chemical effects of multiple acids. The lower carbon content of alloy 317L makes it resistant to intergranular corrosion. At higher temperatures, it has a higher tensile strength. Many of the normal hot working processes were used to make them. It is heated to temperatures ranging from 1149 to 1260 degrees Celsius. The temperature does not exceed 927 degrees Celsius. It is subjected to a post-work annealing procedure in order to maintain its higher corrosion-resistant properties.

We are always concerned with adhering to the compilation of national and international standards and requirements. Our Stainless Steel tubes are brimming with plenty of advantages. High resistance to pitting, crevice corrosion, and stress corrosion cracking, as well as better heat conductivity and lower thermal expansion than austenitic steels, are only several of the advantages. Our whole team has been keeping our best service commitment. A devoted and driven team is our greatest advantage. We remain committed to supplying consumers with high-quality goods and services. As multinational manufacturers, we configure our goods to globally accepted specifications to ensure product consistency. To store these developed Stainless Steel 317L Heat Exchanger Tubes, we have high-tech storage facilities.

We perform the following tests in the initial stage: hardness test, thermal conductivity test, leakage test, positive substance test, intergranular corrosion test, and mechanical test. Third-party officials conduct the final inspection. Furthermore, secondary tests include disruptive, compression, and tensile tests, among others.
