Carbon Steel Pipes and Tubes (A53 Grade B) that we offer are widely used for mechanical and pressure applications. We make available our Carbon Steel Pipes and Tubes in different sizes and thicknesses to suit varied application requirements.

 
Scope : Covers Seamless and Welded, Black and Hot-Dipped Galvanized nominal (average) wall pipe for coiling, bending, flanging and other special purposes and is suitable for welding. Continuous-Welded pipe is not intended for flanging. Purpose for which pipe is intended should be stated on order.
Materials and Manufacture : The steel for both seamless and welded pipe shall be made by one or more of the following processes: open-hearth, electric furnace, or basic-oxygen. The weld seam of electric-resistance welded pipe in Grade B shall be heat treated after welding.
Hot-Dipped Galvanizing : Sets standards for coating of pipe with zinc inside and outside by the hot-dipped process. Weight of coating must not average less than 1.8 oz. per square foot and not less than 1.6 oz. per square foot.
Permissible Variations in Wall Thickness : The minimum wall thickness at any point shall not be more than 12.5% under the nominal wall thickness specified.
Permissible Variations in Weights per Foot : Plus or minus 10%
Number of Tests Required

• Seamless and Electric-Resistance-Welded -- Bending, flattening, tensile on one length of pipe from each lot of 500 lengths or less of a size.
• Continuous-Weld -- Bending, flattening, tensile
