The majority of governmental agencies regulating drinking water supplies require that any product made or used in North America for the manufacture, distribution, or treatment of drinking water or drinking-water-related products must comply with the standards set forth in NSF/ANSI 61: Drinking Water System Components – Health Effects. These regulations apply to every component at every stage of the production process, from cement and paint to meters, valves, and gaskets.

In today’s changing landscape, there are more options than ever in the power generation industry; from natural gas, fossil fuels, coal, and nuclear to renewable methods such as hydroelectric, wind, solar, and biomass, energy can be produced in a variety of ways.

Hydrogen fluoride is a dangerous but critical component for various applications in the chemical processing industry, including gasoline production, specialty metal manufacturing, glass etching and polishing, stainless steel pickling, and semiconductor preparation. When mixed with water, hydrogen fluoride forms hydrofluoric acid, a corrosive fluid capable of causing severe burns and irritation if processes are not properly managed.

The Problem: Sealing Evaporator Dome Lids

Frequently used in the pulp and paper industry, multiple effect evaporators boil water through a sequence of vessels held at increasingly lower pressures. Because a reduction in pressure lowers the boiling temperature of water, only the first vessel in the series requires a heating source.

We are often asked about the differences between elastomeric (or soft) and hard gaskets, and which style is better suited on hinged and bolted manways. 

From a technical standpoint GRI feels the “hard” style gaskets are better suited for several reasons.  This is important because hinged and bolt manways are the number one cause of non-accident releases (NARs) in the industry.
