ASTM B241/B241M-16 pdf free download.Standard Specification for Aluminum and Aluminum-Alloy Seamless Pipe and Seamless Extruded Tube.
1.1 This specification covers aluminum and aluminum—alloy searnlcss pipe in the alloys (Note 1) and tempers shown in Table I [Table 2] and seamless extruded round lube in the alloys and tempers shown in Table 3 (Table 4] intended for pressure applications. The standard sizes for seamless pipe are listed in Table 16.7 of ANSI H35.2 and H35.2(M). Nonstandard alloys. tempers. and sizes of pipe are produced as seamless extruded tube. Also included in this standard are seamless extruded pipe and seamless extruded tube for Oil & Gas Transmission previously covered under Specification
B345/B345M.
3. Ternilnology
3. 1 Definitions of Ternis Specific to This Standard:
3. 1 .1 alcliad seaniless pipe or alclad seamless round tube, n—a composite pipe or tube product composed of a seamless aluminum alloy core having on either the inside or the outside surface a metallurgically bonded aluminum or aluminum-alloy coating that is anodic to the core, thus electrolytically protecting the core against corrosion.
3.1.2 capable of adj—the test need not be performed by the producer of the material. However, should subsequent testing by the purchaser establish that the material does not meet these requirements, the material shall be subject to rejection.
3. 1 .3 extruded seamless alc!ad tube, n—a composite round tube product composed of an aluminum alloy core having Ofl either the inside or outside surface a metallurgically bonded aluminum or aluminum alloy coating that is anodic to the core, thus electrolytically protecting the core against corrosion.
3. 1 .4 exti-uded seamless pipe. ti—extruded seamless round tube with standardized sizes of outside diameter and wail thickness commonly designated by “Nominal Pipe Sizes” and American National Standards Institute (ANSI) “Schedule Numbers.”
3. 1 .5 extruded seamless round rube, n—a hollow product having a round cross section and a uniform wall thickness, brought to final dimensions by extruding from a hollow cast ingot or mandrel pierced ingot.
3.1.6 producer ti—the primary manufacturer of the material
3. 1.7 seamless pipe, n—extruded or drawn seamless tube having certain standardized sizes of outside diameter and wall thickness commonly designated by “Nominal Pipe Sizes” and American National Standards Institute (ANSI) “Schedule Numbers.”
3. 1 .8 supplier n—jobber or distributor as distinct from producer.
