Update The new edition for ASME B31.3, Process Piping, has been issued (December 2020). As usual, there are many clarifications, updated references to codes and standards, updates to basic allowable stresses and . Following exceptions are permitted by ASME B31.3 code: Initial service leak test in lieu of hydrostatic leak test may be carried out for piping systems in Category D fluid service. A pneumatic test or a combined hydrostatic-pneumatic test may be proposed as an alternate test if the owner considers a hydrostatic leak test to be impracticable. Specific requirements were added for double seated valves. Table 323.2.2A, “Tabular Values for Minimum Temperatures Without Impact Testing for Carbon Steel Materials,” was revised in its entirety. . Threaded joints and tubing joints no longer needed to be leak tested in accordance with the ASME B31.3 leak test. Current B31.3 Toughness Testing Requirements • Table 323.2.2 Austenitic Stainless Steels: B- 4 Base metal and weld metal deposits shall be impact tested in accordance with para. 323.3. • When impact testing is required by Table 323.2.2, paragraph 323.3.4 and sub-paragraphs require Charpy impact testing at a temperature not higher than the
ASME B31.3 requires leak testing of all piping systems other than Category D systems. For piping in Category D Fluid Service, the piping may (at the Owner's option) be put in service without a leak test and examined for leakage during the initial operation of the system. . 14.1 Overview of Pressure Test Requirements. 14.2 Hydrostatic Test. 14 . ASME B31.3 • Impact Testing (Paragraph 323.2.2, Paragraph 323.3.1) - For most carbon steels, impact testing during the welding procedure qualification was changed from being required for the weldment for design minimum temperatures below -29°C (-20°F).

ASME B31.3 contains requirements for piping typically found in petroleum refineries; chemical, pharmaceutical, hydrogen, textile, paper and pulp, power generation, semiconductor, and cryogenic plants; and related processing plants and terminals. . Impact Testing (paras. 323.2.2, 323.3.1) Flange Attachment Welds (para. 328.5.2) Heat Treatment .
The design minimum temperature is required to determine the impact test requirements of ASME B31.3. As the temperature is decreased, the notch toughness of the material drops. Thus, impact tests are required under conditions of sufficiently low temperature and high stress to ensure that the material has adequate toughness to avoid a brittle fracture. .
requirements permit moderate energy piping to be hydrostatically tested using the initial service leak test at the system operating pressure in lieu of a higher-pressure hydrostatic test . This is consistent with B31.3 requirements for Category D fluid service. Therefore, permitting a system
Application Flexibility: ASME B31.3 allows for higher allowable stress for the same materials at the same temperatures compared to ASME B31.1, reflecting its use in less extreme conditions. Process Piping Focus: This code is particularly suited for the various piping requirements in chemical and processing plants, where systems might involve a .

IT doesn't require impact test either on material or in PQR as per most of the international codes including ASME B31.3 upto -196 Deg C if I am not wrong. But some oil and gas clients specification asks for impact test for PQR for cryogenic application. there is nothing to do with international code. Figure 1 This chart, which approximates ASME UCS-66 and appears here for illustrative purposes only, shows four temperature functions for impact testing. If an alloy is listed as belonging to Curve C, its thickness is 3.5 in., and the MDMT is 60, it is above the curve and does not need an impact test.
The 2014 Edition of ASME B31.3, Process Piping [1], introduced significant changes to the post weld heat treatment (PWHT) requirements for P-No. 1 carbon steel materials. In particular, PWHT is no longer a mandatory requirement for any wall thickness provided that multi-pass welding is employed for wall thicknesses greater than 5 mm (3/16 of . Table A-1 and Table A-1M of ASME B31.3 code contain the minimum design metal temperature for which the material is normally suitable without impact testing. . is established by para. 323.2.2 and other impact test requirements.

The ASME B31.3 Code defines unlisted components as components not in Tables 326.1, A326.1, or K326.1. Unlisted components can have pressure ratings but the owner and/or the designer has the responsibility to verify that the design, materials, fabrication, examination, and testing of the component meet the requirements of ASME B31.3.ASME B31.3 Process Piping Minimum Temperature For Impact Testing . Calculate ASME B31.3 process piping minimum temperature for impact testing from wall thickness and material type. For carbon steel materials with a minimum temperature letter designation, the minimum temperature for testing can be calculated according to table 323.2.2A (curves A .When conducting a leak test as per ASME B31.3, several requirements outlined in para. 345.2 must be considered to ensure the effectiveness and safety of the testing process. These requirements cover various aspects, including pressure limitations, examination for leaks, heat treatment, and special provisions for testing specific components.
ASME B31.3 for example requires a lateral expansion of 0.38mm for bolting materials and steels with a UTS exceeding 656N/mm 2, rather than specifying an impact value.
