To begin, a Mill Test Report (MTR) in the world of sanitary process is a quality assurance document that documents the chemical and physical properties of the stainless steel (or other alloys) used in the fabrication of hygienic process components and equipment. MTRs go by a variety of names, including Certified Mill Test Report (CMTR), Mill Certification, or Metallurgical Test Report. When a heat (lot) of steel is generated at the mill, it is assayed. The results of that assay are recorded and an MTR is generated.
Stainless steel is a generic term that refers to a variety of types of steel. But what is it that makes stainless steel “stainless” and why is stainless steel the material of choice for sanitary process components? This post will focus on those questions and provide insight into term that is often oversimplified
One piece of instrumentation that we try to specify with all installations, but not surprisingly see underutilized, are sanitary pressure gauges. Cheap and often overlooked, this post will take a look at how we can use a sanitary pressure gauge to help monitor pump performance.
