2008年12月26日 · A Mill Test Report or MTR is documentation from a testing facility that usually shows the chemical makeup and physical strength/properties of materials required to meet certain ASME and ASTM grades.

2010年3月26日 · The purpose of mill certifications is to verify that the material performs within the RANGE required by ASTM. In nearly all cases, I would avoid using mill certificates for design properties. As StructuralEIT noted, "in-place" steel would be the rare occasion where test coupons are the only information available.

2006年8月1日 · The post fabrication hydro test of 1.5 times the design pressure can bring the resultant stress close to the yield stress. Why is that the mill test pressure required much lesser.

2007年8月14日 · Do I need mill test for tubes to be installed on a Power Boiler built according to ASME Section I? hcjulien

2006年5月3日 · A pipe with mill test pressure of about 3.5 times my design pressure? How does mill test pressure guide me in evaluating the suitability of the material [pipe, say] for my requirement?

2015年12月9日 · I didn't realize that in your question you were referring to the mill test pressure and the test limits / calculations in API 5L. I must admit I hadn't realized that the test stress in API 5L was 0.6 SMYS for grades up to grade B and then varying up …

2016年4月12日 · And the vendor submitted MTC for the metareials to be used for this project. And I found that the date in the MTC is about four to five years back. When I raised my concern the vendor responded that they're using the material that is available with them but how old of the material and test certificate be approved ???

2010年5月31日 · Do you guys typically request certificates of compliance (COC) or mill test reports (MTR) from the vendor to confirm that the pipes they want to use meet ASTM standards? Per specifications, the pipes need to meet ASTM A53/A53M for steel, and ASTM B88 for copper. These pipes will be used for...

2011年4月20日 · Ladies/Gentlemen, I am presently working in Luanda Angola as a Resident Engineer on a construction Project. The Contractor has submitted Mill Test Certificates in order to verify if the reinforcing steel Ø 20mm and Ø32mm satisfies the requirements of BS 4449 Grade 460. In terms of the Geometric...

2003年1月6日 · C-E marking on a mill test report is non-sense. The PED requires that for pressure part materials, the mill supplies a certificate of specific product control. In other words a mill certificate including test reports as per referenced material standard. The tests shall be witnessed by an approved third party of the Community.
