#DIFFERENCE BETWEEN B31.3 AND B31.8 MANUAL#

When pipe materials joined have different yield strengths and unequal wall thicknesses, taper boring and special beveling in accordance with ASME B16.25 under the following is to be used as follows:ДЄ. The end preparations and geometry shall comply to ASME B16.25.ДҐ.1.2 Joints Between Piping of Unequal Strength, with Different Walls When the wall thickness ratio of the two pieces is greater than 1.5, a combination of taper boring and weld end preparation is used. When the wall thickness ratio of the two pieces is less than or equal to 1.5, the thicker wall is taper bored in accordance with the respective ASME B31 design code.Д«. The joint details for piping of equal strength, and different wall thickness shall be as follows:ДЄ. Welds in metallic piping shall conform to the requirements of SES W05-F02 and other Standards referenced therein.ДҐ.1.1 Joints Between Piping of Equal Strength, with Different Walls Pipe Weld Joints in Plants and Pipelines | ASME B31 Piping Code General Requirements DefinitionsДЇor the purpose of understanding this standard, the following definition applies.ДЇluid services that are deleterious to human health, or will contribute to a fire, areД¬onsidered hazardous.
