Wujiang, Jiangsu, P. The primary purpose for this development was the increasingly severe temperatures and pressures used by U. Metal Strip Filler Material The necessity for a gasket to have the ability to recover cannot be over emphasized. The effects of pressure and temperature fluctuations, the temperature differential across the flange face, together with bolt stress The color on the outside edge of the centering ring identifies both the winding and filler materials. The metallic winding material is designated by a solid color.

Play Video Traditional sealing solutions are inadequate for ethylene production. The oxidising environment and thermal cycling, exacerbated by regular decoking sessions, create harsh operational conditions that put plant equipment under significant stress.
Tests and operational experience have shown that choosing the right sealing gaskets and materials can make the difference between joint failure and efficient production. Download the technical paper to find out more. Thermal cycling As a result of maintenance shutdowns, decoking sessions and the cooling process, thermal cycling causes expansion and contraction of joints.
An effective sealing solution must be able to respond and adapt to this recurring demand. Oxidation The oxidising environment created by the high temperature steam and decoking sessions initiates an oxidising reaction with traditional sealing materials, which means they lose mass and ultimately cause leaks.
Download the technical paper Choosing the right sealing solution in ethylene production The operational challenges of ethylene production call for a thorough approach to gasket selection. In this technical paper, our experts describe the sealing challenges caused by the oxidising environment created by the superheated steam, thermal cycling and regular decoking sessions, highlighting the hotspots where traditional sealing solutions are known to cause joint failure.

Flexitallic Spiral Wound & Metal Gaskets
It is customary to select inner ring material to be the same as the metal winding. The traditional spiral wound gasket has its steel windings protruding above the compression stop. See Traditional vs. This requires a significant loading stress to compress the gasket to its optimum operating thickness. They are usually round, obround or oval shape, depending of course, upon the manhole plate configuration.
