Home / Spacers / Standard Full Face Spacer: Thermoplastic Flange Spacing for Lined Pipe Systems

A Standard Full Face Spacer, also commonly referred to as a full-face flange spacer or full-coverage flange spacer, is a precision-cut thermoplastic component designed to cover the entire surface area of a flange (including bolt holes) while allowing uninterrupted flow through the piping system. Unlike ring spacers, full face spacers provide enhanced sealing support and uniform load distribution across the flange face.

Overview

SG-P manufactures Standard Full Face Spacers specifically for lined-pipe systems, ensuring precise alignment, excellent chemical resistance, and dependable long-term performance in corrosive and non-metallic environments.

What Is a Standard Full Face Spacer Used For?

Standard Full Face Spacers are used when full flange coverage is required while maintaining flow through the pipeline. They are commonly installed to improve gasket sealing, distribute bolt loads evenly, and protect flange faces from chemical attack.

Typical uses include:

  • Enhancing gasket sealing and flange protection
  • Maintaining proper flange spacing in lined-pipe systems
  • Compensating for gasket thickness or compression
  • Providing dielectric and thermal isolation
  • Improving load distribution across the entire flange face

Applications and Industries

Standard Full Face Spacers are widely used in industries that require corrosion-resistant, non-metallic piping components:

  • Chemical & Petrochemical Processing: protection and sealing support in corrosive service
  • Water & Wastewater Treatment: durable flange spacing and isolation components
  • Pharmaceutical & Food Manufacturing: non-contaminating, corrosion-resistant applications
  • Power Generation & Utilities: thermal/dielectric isolation and spacing support
  • Marine & Offshore Systems: corrosion-proof components in harsh environments
