ASTM B515-95 pdf free.Standard Specification for Welded UNS N08120, UNS N08800, UNS N08810, and UNS N08811 Alloy Tubes.
This specification covers welded UNS NO8120，UNSN08800，UNS N08810 and UNS N08811 alloy boiler， heatexchanger, and condenser tubes for general corrosion resistingand low or high-temperature service.This specification covers tubes 1/s to 5 in. (3.18 to 127mm), inclusive, in outside diameter and 0.015 to 0.500 in. (0.38to 12.70 mm), inclusive, in wall thickness.Table 2 of Speci-fication B 751 lists the dimensional requirements of these sizes.Tubes having other dimensions may be furnished providedsuch tubing complies with all other requirements of thisspecification.
The values stated in inch-pound units are to be regardedas the standard. The Sl units given in parentheses are forinformation only.This standard does not purport to address all of thesafety concerns，if any,associated with its use. lt is theresponsibility of the user of this standard to become familiarwith all hazards including those identified in the appropriateMaterial Safety Data Sheet for this product/material as provided by the manufacturer; to establish appropriate safety andheal practices，and determine the applicability of regulatorylimitations prior to use.Tube shall be made from flatrolled alloy by an auto-matic welding process with no addition or filler metal.Subse-quent to welding and prior to final annealing, the material shallbe cold-worked in either the weld metal only or both weld andbase metal.Tube shall be furnished with oxide removed. Whenbright annealing is used, descaling is not necessary.
The material shall conform to the composition limitsspecified in Table 1. One test is required for each lot as definedin Specification B 751.
If a product analysis is performed,it shall meet thechemistry limits prescribed in Table 1, subject to the analysistolerances specified in Table 6 of Specification B 751.Mechanical and Other Properties: Mechanical Properties-The material shall conform tothe mechanical property requirements specified in Table 2.Onetest is required for each lot as defined in Specification B 751.A transverse sample representing the full-wall thickness of annealed alloys UNS N08120,N08810,andN08811 shall conform to an average grain size of ASTM No.5 or coarser.A flattening test shall be made on eachend of one tube per lot. Superficial ruptures resulting fromsurface imperfections shall not be cause for rejection.A flange test shall be made on each end ofone tube per lot.ASTM B515 pdf download.
