John Brady owns Standard of New England with his wife, Julie. He started the business in 1996 when the opportunity to purchase a failing company and turn it around presented itself. First learning about piping systems on board U.S. Coast Guard Cutters, and then at a very well-respected supplier in the Boston area, John jumped into his new business ready to learn and grow. He enjoys sharing what he has learned over the years with engineering teams, estimators, maintenance managers, pipe fitters, procurement departments, and project managers across a wide range of industries in need of complex, high-energy piping systems. Born in Boston, John now lives in the beautiful Seacoast region of New Hampshire with Julie and their three dogs: Rosalie, Emma, and Jasmine.

Why are Spiral Wound Gaskets So Popular?

The spiral wound gasket’s popularity is due to several factors:

•  It is ideal in high temperature, high-pressure, and corrosive applications.
•  A wide variety of available gasketing material allows
     engineers, contractors, and industry professionals to tailor the gaskets
     to their specific application. (See material options, below.)
• 
The v-shaped metal strip, called the winding, forms a tight seal with spring like qualities.
• 
It creates an excellent seal once compressed under the load of bolts or studs.
• 
Upon compression the filler fills minor imperfections in the flange facing creating a near perfect seal.

There are many types of spiral wound gaskets, the most common four are:

CG Style– The most commonly used and widely available configuration of spiral wound gaskets. CG Style gaskets have a solid metal ring on the outer diameter referred to as the centering guide (CG). This guide allows the installer to more accurately center the gasket on the flange face while providing strength on the outer ring. CG style gaskets are used with both flat and raised-face flanges in a wide variety of applications.

CGI Style– Like the CG Style described above, CGI gaskets have an outer ring, but they also offer an internal ring protecting the inner diameter of the gasket against heat, corrosion and blow-outs making it ideal in vacuum applications. CGI Style gaskets can be used with both flat and raised-face flanges.

R Style– The most basic configuration of spiral wound gaskets, the R-Style consists of only the metal winding and the filler materials. The inner and outer diameter are reinforced by several layers of the winding material without the filler. The inner portion of the R-style gasket is made up of winding and filler material. This style is used with tongue and groove, flat-faced to grooved, and male to female flange connections. They are also regularly used in valve bonnets and pump casings. 

RIR Style– Is similar to the R-Style gasket in its basic construction but has an inner liner ring that acts as a reinforcement. The inner ring creates a compression stop and fills the void between the inner diameter of the gasket and the flange bore. This reduces the accumulation of solids and reduces tubulation of fluids. RIR-Style gaskets are used on male and female flange connections.
