The figure below illustrates the standard components of a spiral curve connecting tangents with a central circular curve. The back and forward tangent sections intersect one another at the PI.

From the first Spiral Wound Gasket in 1912 to the ever evolving applications for Thermiculite®, our goal is to develop materials that push the parameters of heat, pressure and chemical resistance.

All dimensions are in millimeters Spiral Wound gasket with Inner - and Outer ring d1 = Inside diameter Inner ring. d2 = Inside diameter sealing element when no Inner ring is used. d3 = Outside diameter of …

As an extension of TxDOT’s Roadway Design Manual Chapter 14, this aid provides designers with guidance for the development of multilane roundabout lane configurations that may require one or …

Designed to achieve an effective seal under the most demanding operating conditions, the Spiral-Max pro-file is engineered to provide recovery in applications where the load on the gasket may vary due …

The Spiral Wound Gasket with center Ring is for use w ith flat face and raised face flanges, this gasket features increased compressive force for blow-out prevention.

Eastern Sheet Metal fittings are sized to slip into, and should be used with, Eastern Sheet Metal spiral duct. A tight fit is necessary to minimize friction loss and to promote proper sealing.
