ASTM B704 Tubing

Manufacturer, Supplier and Exporter of Inconel Alloy ASTM B704 Tubes, ASTM B704 Tubing, ASTM B704 Welded Tubes

We, Steel Tubes India, are manufacturers and suppliers of ASTM B704 Tube and we sell these tubes in sizes of 6.00 mm OD to 914.4 mm OD and thicknesses of 0.3 mm – 50 mm, SCH 160, SCH10, SCH 5, SCH 80S, SCH 40, SCH XXS and SCH 80. These tubes are available with us in lengths within 13,500 mm. The type of these tubes that we have with us is Welded Tubes and we sell these in grades of UNS N08825, UNS N06219 and UNS N06625. In this specification of ASTM B704, is included Inconel 625 Welded Tubes and Incoloy 825 Welded Tubes, which are in big demand for use against specific kinds of chemical attacks.  

Incoloy 825 Tube is a welded steel tube, that has been produced with a spiral seam or a longitudinal seam. In the start of the manufacturing process of welded Incoloy 825 Tubes, the material is flat rolled. And depending upon the application used, the tube dimension and the type of manufacturing process used, the tube may take the form of hot rolled tube or hot-cold rolled steel.

Inconel 625 Tube are manufactured using a high performing nickel–iron–chromium alloy, to which has been added copper, titanium and molybdenum. Because of this, welded tubes made from Incoloy 625 show very good resistance to reducing acids, as well as to oxidizing. Not only that, but these types of tubes also display superb resistance to corrosion from sea water, phosphoric acid and sulfuric acid. Plus, these tubes also show excellent resistance to localized attacks like pitting and crevice corrosion and also to SCC. Because of this, these welded tubes made from Incoloy 625 are used in high-pressure systems that call for excellent resistance and high-strength.

To ensure that we, Steel Tubes India, supply only the best quality ASTM B704 Welded Tube, we run all our tubes through the strictest of quality tests, some of which include Flattening Test, Pitting Resistance Test, Hardness Test, Micro and MacroTest, Intergranular Corrosion Test, Spectro Analysis, PMI Testing, to name a few. We also provide our clients with Standard Certificates such as Raw Materials Certificate, Third Party Inspection Report, FERRIT Content, 100% Radiography Test Report, etc. We even supply our clients with Test Certificates certifying NACE MR0103 and NACE MR0175. As such, you can be sure that our quality is the best you can get, anywhere!
