Clear labels are tagged on the outside of the package for easy identification of the quantity and product I.D. Great care is taken during operation and transportation. A213 Grade T9, T11, T12, T22, T91 Alloy Steel Welded Tube packing will be according to international standard in bundles strapped by strips then into containers to avoid any damage.

Alloy Steel contains substantial quantities of elements other than carbon like chromium, silicon, nickel, manganese, molybdenum, tungsten, vanadium as well as limited amounts of other commonly accepted elements like sulphur, manganese, silicon & phosphorous. Addition of these alloying elements is usually done for purpose of increasing hardness, strength as well as chemical resistance of the end product. Alloy Steel Seamless Tubes (IBR) offered by us is made of alloy steel and feature exceptional performance properties. These are developed for energy-related applications involving oil & gas drilling and therefore are subjected to stresses in machine parts. Further, Alloy Steel Tubes are also used in domestic, professional or industrial areas.

We have been supplying high quality ASTM A213 Grade T12 Alloy Steel EFW Tubes with most advance technology and with most reliable quality. We place importance not just on managing material sales, but also on 'before' and 'after service'.
