This information must match the order requirements. In the case of plate material this would be the thickness, round bar the diameter, or flat bar the thickness and width. The MTR identifies the applicable dimensions of the raw material. The product specifications that the raw material meets are listed on the CMTR. Often but not always the ASTM and ASME specification are identical. A240, while ASME specifications are prefixed by a “SA”, e.g. ASTM specifications are prefixed by an “A”, e.g. ASME material specifications are required when fabricating Pressure or Vacuum Vessels to the ASME Boiler and Pressure Vessel Code. CMTR’s certify that the raw material meets the appropriate American Society for Testing and Materials (ASTM) or American Society of Mechanical Engineers (ASME) material product specification. The MTR identifies the grade of the material.
Metal materials are produced in various grades. When matching an MTR to its raw material all accompanying paper work and in many cases markings on the raw material itself must match the heat number on the MTR. The heat number is used to maintain traceability of the material. Material manufacturers can identify raw material in different ways, using lot, coil or other identifying numbers, but ultimately all MTRs will identify the material with a Heat Number. This being another way we support our promise to Reduce Project Risk and achieve the lowest total cost of ownership for our customers Below we have summarized what our engineers are reviewing, so that only the correct materials are issued to the shop for manufacturing. The Project Engineer is responsible for review of the MTR to ensure it meets the engineering and order requirements. MTR’s are also used to maintain traceability of the material from its initial inception to its inclusion in a finished part.Īt most manufactures or fabricators, it is the Receiving Department’s responsibility to match received goods to supporting MTRs and forward that information to the Project Engineer.
Mtr report verification#
Whether it’s called a CMTR, Mill Test Report (MTR), Mill Certification, Metallurgical Test Report, or similar name, this document provides the end user of the raw material verification that the material received matches the requirements of their order. Think of the MTR as the DNA, this is one part of creating the birth certificate for your project or manufactured product.Ī Certified Mill Test Report (CMTR) is a quality assurance document generated by the raw material manufacturer and provided with the material to intermediate suppliers and ultimately to a finished goods manufacturer. The Certified Mill Test Report is a tool used to ensure that received raw material matches the engineering and purchase order requirements.
Whether manufacturing a subsea pipeline or a small skid package, using the correct material as determined in engineering for each component is critical.
