Understanding and Choosing Waterworks Valve Flanges

Understanding and Choosing Waterworks Valve FlangesPART TWO: Construction and Installation

(Ed. Note: The first part of this article is available in the Fall 2014 issue of VALVE Magazine. Read the online version HERE.)

Part One provided a thorough explanation of the variables and ratings that affect flange ratings. But that’s only a piece of the picture. This article, part two, describes how flanges are produced and the accepted methods for use and installation.


Innovative, Practical Corrosion-Resistant Coatings

Innovative Practical Corrosion-Resistant CoatingsLike anything made of metal, valves are subject to corrosion that compromises performance. Aluminum alloys are widely used for valves because of their low density and positive mechanical properties. Unfortunately, serious corrosion problems can occur when aluminum alloys are exposed to corrosive environments.


Magnetic Valve Breakthrough

Magnetic Valve BreakthroughThe topic of controlling or monitoring fugitive emissions is an ever-present discussion in the valve community. Regulation standards get tighter and environmental impacts continue to drive innovation as new technology is released. A trustworthy valve or valve actuator that completely eliminates fugitive emissions might be considered the Holy Grail of the industry for particular applications.


Equipment Mapping Process Streamlines Repairs

Equipment Mapping Process Streamlines RepairsAll of industry relies on properly working equipment and well-trained staff to operate and maintain their facilities. However, when staff relies on outdated information or incorrect tagging, the risk of serious safety and reliability problems increases as does the cost of doing business.

Anyone who has provided valve repair services for any amount of time will have run into situations where certain elements necessary to complete a job were missing. It might be that an unknown safety factor for the removal of a piece of equipment did not come to light until the start of the job.


Repairing Hydraulic Servo Valves in Seismic Vibrator Trucks

Seismic Vibrator TrucksSeismic vibrator trucks (aka “thumper trucks”) send shockwaves deep into the earth’s subsurface to locate untapped hydrocarbon reserves for the oil & gas industry.

These shock/soundwaves reflect back to the surface, where they are picked up and recorded by geophones. This seismic data is later imaged with advanced software (think: ultrasounds) and analyzed by geologists who advise oil companies on where to drill for oil reserves.
