Cross Section
|
Available in a full range of styles and materials, our spiral wound gaskets are manufactured in accordance with ASME B16.20 for use in all industry flanges, including ASME/ANSI B16.5, ASME B 16.47, Series A & B. T.C.I assures strict adherence to these specifications as routine inspection procedures are applied throughout the manufacturing process. In addition, we maintain trace ability of all materials used in our gasket construction to provide material certifications as required.

ASP-R
|
Spiral Winding Only |
This style of gasket consists of the winding/sealing element only. It has no guide ring (centering ring) or inner ring. It is most commonly used in tongue and groove and male/female flanges. |
|
|
ASP-IR
|
Spiral Winding with Inner Ring |
This gasket is similar to the ASP-R, however, it has an inner ring. Its application is similar to the ASP-R. |

ASP-CG
|
Spiral Winding with Outer Guide |
The ASP-CG is the most common profile of spiral wound gasket and used extensively in ANSI B16.5 flanges. The gaskets consist of a metal guide ring (or sometimes referred to as a centering ring) and a spiral wound sealing element. This profile is normally used in raised and flat faced flanged. The outer ring is often made of carbon steel (painted or zinc plated to prevent corrosion) but can be made of alloys for higher temperature and more severe medium applications. |

ASP-CGI
|
Spiral Winding with Outer Guide and Inner Ring |
This gasket is identical to the ASP-CG, however an inner ring has been inserted to enhance gasket performance. The inner ring is added to prevent the possibility of the gasket imploding into the pipe during installation, to protect the sealing element from extreme temperatures and mediums, fill the void between flanges to prevent erosion of the flange, and to reduce the possibility of failure. The inner ring is normally made of the same alloy as the winding. The DIN 2699 standard (German) specifies inner rings in all spiral wound gaskets. Inner rings are required for gasket with PTFE filler according to ASME B16.20 standards, and considered important for graphite fillers. This profile is normally used in raised and flat faced flanges. |
