Changing the Way Americans Think About Manufacturing Careers

The Valve Manufacturers Association is focusing a major effort on developing a solution to a problem that plagues this industry as well as most of the industrial world: how to find and attract talented new workers. While VMA can help in forming a solution, the association can’t do it alone—industrial companies themselves need to rethink recruiting methods and ways to improve the image of manufacturing and heavy industry.

Hazards in Chlorine Piping and the History of a Solution

North America relies on chlorine for many industrial processes and for making the ingredients that go into many of the nation’s chemicals. But using it carries a certain amount of risk. Among the solutions for handling those risks is the bellows seal metal-seated globe valve. This article outlines the hazards and how this solution was born.

2016 Market Forecast: Dodging Market Strikes

Discussion of crude oil and natural gas have dominated much of the last few VMA Market Outlook Workshops and this year’s event, which was Aug. 6-7 in Chicago, was no different: Declining oil prices made it into most discussions at the workshop, and shale gas came up many times. However, a few other issues also seemed to bounce off the walls and return repeatedly to the list of ­concerns among the assemblage. Among them: China’s current ­economic doldrums and the high U.S. dollar.

Coatings can Make a Difference in Wastewater

15 sum wastewater introIn Episode 23 of the Discovery Channel’s “Dirty Jobs,” Mike Rowe had the task of pulling a submersible wastewater pump from a lift station for inspection and cleaning. His exposure to fumes, sewage and sludge while accomplishing this task undeniably demonstrated the need to reduce maintenance and repair in the wastewater industry wherever possible. The images conveyed showed how messy wastewater equipment can get and why costly downtime occurs in this industry.

Understanding and Selecting Valve Flanges, Pt. I: Design and Standards

14 fall flanges introFrom time to time, we are re-posting particularly well-received articles that have previously run on VALVEMagazine.com so that those who might have missed them will be able to catch up on the best of the best. This article, Understanding and Selecting Valve Flanges, Pt. I: Design and Standards, was Number 2 on our Top Ten online Stories of 2014 and initially ran on November 14, 2014.

Because flanges allow the assembly and maintenance of system components without the need for cutting and welding pipe, they play an important role in piping systems. However, the structural integrity and leak tightness of waterworks piping systems are only as strong as the weakest element, which often is the flange connection between various valves and fittings. Yet because piping systems are subject to many types of loads and are constructed of a variety of materials, understanding and predicting the rating and performance of those flange connections is difficult. This is further complicated by the fact that different sealing mechanisms such as gaskets, O-rings and mechanical seals can significantly affect the performance of the connections. As far as ratings, ASME B16.1 lists pressure ratings for Class 125 flanges from 50 to 200 psig depending on size, material and temperature.
