| Introduction FIRST AND FOREMOST The concept of spiral wound gasket construction was originated by Flexitallic in 1912, inaugurating the beginning of a new era in safe. effective sealing. The primary purpose for this development was the increasingly severe temperatures and pressures used by U.S. refinery operators in the first half of the century. 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 relaxation and creep, demand a gasket with adequate flexibility and recovery to maintain a seal even under these varying service conditions. The Flexitallic Spiral Wound Gasket is the precision engineered solution to such problems, meeting the most exacting conditions of both temperature and pressure in flanged joints and similar assemblies and against virtually every known corrosive and toxic media. This publication is designed to facilitate the specification and ordering of standard Flexitallic Spiral Wound Gaskels. Dimensional data for the basic styles - Style CG, Style CGI, Style Rand Style RIR are detailed on respective tables. |
STYLE LS & LSI LOW STRESS RANGE OF SPIRAL WOUND GASKETS Tho LS gasket offers the same high integrity seal associated with the spiral wound gasket however the LS and LSI has been designed in such a way that compresion and sealing requirements are achieved under very low seating stresses. These gaskets are intended for use on class 150 and 300 applications where customers traditionally do not use spiral wound gaskets due to concerns about exceeding allowable design stresses.
Tho traditional spiral wound gasket has its steel windings protruding above the compression stop; this requires a significant loading stress to compress the gasket to its optimum operating thickness. The LS and LSI gaskets have only soft Flexicarb or PTFE filler protruding above metal windings and guide ring; therefore as the gasket is compressed, the Flexicarb, Thermiculite 836 or PRFE filler is readily compressed thus productin the sealing mechanism at an earlier stage as compated to the conventionally manufactured sprial wound gasket.
