CONTINUOUS-WELDED pipe is not intended for flanging (roll back operation to form flange using pipe wall). A-106 Covers SEAMLESS carbon steel nominal wall pipe for high-temperature service, suitable for bending, flanging and similar forming operations. NPS 1-1/2 and under may be either hot finished or cold drawn. NPS 2 and larger shall be hot finished unless otherwise specified. SPEC HOT-DIPPED GALVANIZING A-53 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. A-106 Not covered in specification. SPEC PERMISSIBLE VARIATIONS IN WALL THICKNESS A-53 The minimum wall thickness at any point shall not be more than 12.5% under the nominal wall thickness.

NOTE: NPS 4 and smaller-weighed in lots. Larger sizes by length. A500 GRADE B STRUCTURAL PIPE A500B Structural Pipe is manufactured for use in applications that demand greater strength, closer tolerances, and a superior finish. This product is an excellent choice for painted applications such as handrails, commercial architectural applications, agricultural implements and communication towers. A500B Structural Pipe is manufactured in sizes from NPS 1/2 to NPS 9 in schedules 5 to 80. It can also be custom produced to meet your specific needs in outside diameter from.406 to with wall thickness from.035 to.500. TOLERANCES Straightness: 1/8" times the number of feet of total length divided by 5 Length Tolerances Mill Cut: 22 ft. and under -- +1/2"; -11/4" Over 22 ft. to 44 ft /4"; -1/4" OUTSIDE DIAMETER 0.840" to 1.900" incl. -- ±0.5% and larger -- ±0.75% The outside diameter measurements shall be made at positions at least 2" from either end of the pipe.

52 Reduce Your Machining Costs with Dura-Bar Plus Dura-Bar products have always been considered the most machinable cast iron due to strict control of the process variables that govern continuous casting. Recently, extensive tool life tests by independent machine shops and the University of Alabama, Birmingham have been used to establish even tighter control limits on the continuous casting process. The results is new and improved Dura-Bar Plus. Dura-Bar Plus is engineered iron designed to meet our customer s most critical requirements. It is manufactured to strict process controls that give you world-class quality and uncompromising consistency. By using Dura-Bar Plus, you will be able to increase your profit margins by machining more parts per hour, thereby decreasing cycle time and increasing profitability. With Dura-Bar Plus, you will also be able to: Optimize your machining speeds and feeds Lower your tooling costs Decrease downtime for tooling change Reduce scrap In addition, the wide range of sizes and immediate availability of Dura-Bar products eliminate the need for expensive patterns and costly inventories. Together, it all adds up to lower cost per part. Dura-Bar Plus is only available in G2 Gray Iron and in , , and ductile irons. A Commitment to Quality Dura-Bar is a QS-9000 Registered company committed to quality. We maintain our positions as industry leader by producing the most consistently reliable, highest quality bars and tubes. As such, our new Dura-Bar Plus products are sold with a Zero-Defect Guarantee against foundry defects. (For more information about the Zero-Defect Guarantee, go to The Continuous Casting Process Dura-Bar Continuous Cast Iron Bar Stock GRAY IRON The close grain, dense iron permits precision machining at optimum speeds.

53 Austempered Ductile Iron Ductile Iron can be heat-treated to enhance wear resistance and mechanical properties. The standard methods of heat-treating include quench and temper, induction, and flame hardening. In each of these methods the matrix is transformed to martensite, which will be stronger and more wear resistant than either pearlite or ferrite. Another method of heat-treating involves heating the part to obtain austenite and then quenching it above the martensite start temperature but below the pearlite transformation temperature, and holding the part at this temperature for a time that is sufficient to produce an ausferrite matrix. This process is called austempering, and parts that have been heat-treated in this manner are commonly referred to as austempered ductile iron, or ADI. Austempered ductile iron parts have high impact properties, excellent wear resistance, and higher tensile strengths than parts that have been quenched. Any grade of ductile iron can be austempered but it is sometimes necessary to add nickel and copper to produce the desired microstructure in parts that have heavy sections (greater than 2"). The table below contains the expected minimum properties of ADI.
