HELICOFLEX® TEXEAL® Texturized Seal Concept and Overview


HELICOFLEX® TEXEAL® Texturized Seal Concept and Overview

Technetics Group was the first to create the texturized seal concept with the goal of addressing issues with a metallic solution. Texturization has made many advances in the last few years and is now worldly applied thanks to Technetics’ innovation.

The process is simple, fast and reliable. Once the HELICOFLEX® TEXEAL® was designed, there was a series of tests conducted including varying pressures, nuclear conditions, temperatures and more. The HELICOFLEX® TEXEAL® concept allows for the highest seal performance due to its unique design, metallic properties, and rigorous testing.

HELICOFLEX® Spring Energized Seal

HELICOFLEX® Resilient Metal Seal


HELICOFLEX® Resilient Metal Seal


The HELICOFLEX® seal is a high performance, flexible metal seal that has exceptional compression and elastic recovery properties. This seal is composed of a close wound helical spring surrounded by one or more metal jackets. The spring is designed to have a specific compression resistance. During compression, the resulting specific pressure forces the jacket to yield and fill the flange imperfections while ensuring positive contact with the flange sealing faces. Each coil of the helical spring acts independently and allows the seal to conform to surface irregularities on the flange surface.

HELICOFLEX® design flexibility allows Technetics engineers to customize the seal characteristics to match each unique application.
