Product Description

The concept of spiral wound gasket construction was originated by Flexitallic in 1912, inaugurating the beginning of a new era in safe, effective sealing. And we are the main supplier of spiral wound gasket in China. 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 Rilson 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.

Thermiculite®, Rilson'S proprietary

high-temperature, sealing material 

is comprised of chemically exfoliated 

and thermally exfoliated vermiculite.

This revolutionary patented product

simulates the structure of exfoliated

graphite but with one notable

exception … gaskets made with

Thermiculite® maintain their integrity,

even at extreme temperatures.

Thermiculite is thermally stable,

ensuring against thermal oxidation,

at temperatures in excess of

1800ºF (Thermiculite® 835).

NOTES:

Selected materials should be compatible with operating temperature and chemicals. If in doubt, contact Rilson Technical Department.

If PTFE is subjected to temperatures above 250°C (500°F) decomposition starts to occur slowly, increasing

rapidly above 400°C (750°F). Care should be taken to avoid inhaling the resultant fumes, which may produce hazardous effects


Gasket Select

RS1-CG - Utilizes an external ring which accurately centers gasket on flange face, provides additional radial strength to prevent gasket blow-out and acts as a compression stop. A general purpose gasket suitable for use with flat face and raised face flanges up to and inclusive of class 2500. See note at bottom of page 8 for inner ring requirements.

RS1-CGI - A Style CG gasket fitted with internal ring which gives an additional compression limiting stop and provides heat and corrosion barrier protecting gasket windings and preventing flange erosion. Suitable for use with flat face and raised face flanges. See note at bottom of page 8 for inner ring requirements.

RS1-R - Basic construction type. Inner and outer diameters are reinforced with several plies of metal without filler to give greater stability and better compression and sealing characteristics. Suitable for tongue and groove or male and female or grooved to flat face flange assemblies.

RS1-RIR - Solid inner metal ring acts as a compression stop and fills the annular space between flange bore and the inside diameter of the gasket. Designed to prevent accumulation of solids, reduce turbulent flow of process fluids and minimize erosion at flange faces. Suitable for male and female pipe flanges.

Note: Please select correct gasket style for your particular application.

Rilson RS1-CGI Gaskets with spiral wound outer ring are primarily designed for the male and female flanges and are custom built to suit the design conditions of individual heat exchanger vessels.

These gaskets are available in an extensive range of materials. This style incorporates several special features, as follows:

1. The outer wound nose to ensure correct sealing element location in the flange recess.

2. A spiral wound sealing element to ensure a positive seal under fluctuating temperature and pressure conditions.

3. A solid metal inner ring to protect the sealing element and act as a compression stop. As an optional extra, inner rings can also be supplied with nylon location screws to secure the gasket to the flange on assembly.

4. Can be supplied with pass partition bars in any configuration. Pass bars are secured to the inner ring and can be supplied in either solid metal or double jacketed construction.


Recommended Gasket Style

For high pressure/temperature duty, also for gaskets with PTFE filler, corrosive or fluctuating pressure or temperature service conditions.
