8.Q1. Does ABSA require material test reports (MTR’s) for pipe and fittings used in the construction of boilers and pressure vessels?
8.R1. ABSA does not require that MTR’s be provided for pipe and fittings used in the construction of boilers or pressure vessels except for pipe used as the shell of a boiler or pressure vessel or pipe caps used as heads on a boiler or pressure vessel. Otherwise, the requirements of the code of construction with respect to the provision of MTR’s apply. Note that individual manufacturers’ quality management systems or purchase contracts may require that MTR’s be provided for more items than the code of construction or ABSA require.
8.Q2. Is it mandatory that material test reports (MTR’s) for components of ASME Code boilers or pressure vessels state that the material was produced to an ASME (SA or SB) specification, or is it acceptable for the MTR to show an ASTM (A or B) specification number?
8.R2. The Forewords to the various sections of the ASME Boiler and Pressure Vessel Code state the following:
“All materials allowed by these various Sections and used for construction within the scope of their rules shall be furnished in accordance with material specifications contained in Section II or referenced in the Guidelines for Acceptable Editions in Section II, Parts A and B, except where otherwise provided in Code Cases or in the applicable Section of the Code. Materials covered by these specifications are acceptable for use in items covered by the Code Sections only to the degree indicated in the applicable Section. Materials for Code use should preferably be ordered, produced, and documented on this basis; Guidelines for Acceptable Editions in Section II, Part A and Guidelines for Acceptable Editions in Section II, Part B list editions of ASME and year dates of specifications that meet ASME requirements and which may be used in Code construction.” (emphasis added)
This means that one should be in the habit of ordering material to the appropriate ASME SA or SB specification number. However, if the material provided is only documented as meeting an ASTM A or B specification number of a specified edition date and that specification number and date are included in the Guidelines for Acceptable Editions in Section II, Part A or B, the material is acceptable for Code construction within the limitations of the Code of construction. See the second to last paragraph of the Foreword to any Section of the Code for additional detail. The above comments apply equally to non-ASTM material specifications that have been incorporated into Section II under SA or SB specification numbers.
