Alba Corrix EVSM Spiral Wound Gaskets are designed to replace graphite-filled spirals in both seawater and hydrocarbon applications, making them particularly suitable for upstream oil and gas operations. EVSM (Expanded Vermiculite Sealing Material) is a spiral wound gasket filler designed to address the issue of flange corrosion in oil and gas applications. Unlike graphite, EVSM is non-conductive, mitigating the risk of galvanic corrosion inseawater applications.

EVSM gaskets maintain the integrity of traditional graphite filled spiral while offering enhanced tightness and mitigating the risk of corrosion. 

  1. Enhanced sealing performance compared with graphite
  2. Non-conductive – prevents galvanic reaction with flanges
  3. Fire safe to API 6FB
  4. Jointly developed with Dr Gavin Smith/Phoenix Sealing UK
  5. Same installation & torque procedures as graphite
  6. Proven track record & approval
  7. Specified and used in multiple North Sea assets
  8. Manufactured in UK


Full Description

EVSM filled spirals are available with and without retaining rings, and in a wide range of allow materials to ensure compatability with the sealing media and operating conditions. They are engineered to suit standard pipeline flanges as well as non-standard applications, including vessel flanges.   3rd party test reports are available upon request.  Please e mail sales@albagaskets.co.uk
