What’s the difference between filters and strainers?

Oct 22, 2013

So, you have a process that has some particulates in it. You know that you want some or all of these particulates out of the product before you proceed with manufacturing, but you’re not sure how to get started. Do you need filters or strainers? What is the difference between filtering and straining anyway? What does it all mean? These questions are not uncommon...

1. When the product is corrosive to the piping system. Products containing chlorides and other salts can attack the tubing and fittings used to transport the products throughout a plant. Systems fabricated from 304 or 316 stainless steel can become leaky after prolonged contact with salty food and beverages, e.g. sports drinks and soy sauces. If the product is...

Stress Corrosion Cracking

Stress Corrosion Cracking

Sep 17, 2010

Unexpected or premature failure of chemical process equipment constitutes a serious hazard in terms of personnel, plant, and environmental safety. By weakening reliability, such failures also adversely affect productivity and profitability. Modern experience in chemical plants has been that failures due to environmental cracking are among the most serious of such problems, making up about 20 to 30% of all corrosion failures. The purpose of this article is to discuss in simple terms some of the pertinent information.

What Is an MTR?

What Is an MTR?

Aug 26, 2010

An MTR (Material Test Report, or Mill Test Report) is a quality assurance document that lists the chemical composition of a particular material, which is identified by a heat number. It also contains information such as mechanical properties like strength, elongation, hardness and other applicable industry standards. MTRs are typically required for all tube, fittings, and components to be used in high purity systems.
