Use calibrated torque wrenches and avoid over-tightening, which can damage the spiral wound gasket's compression characteristics.
Quality Certification Requirements
ASME B16.20 compliant spiral wound gaskets must undergo rigorous testing including dimensional verification, material certification, and pressure testing. Manufacturers must provide mill test certificates and traceability documentation for all components.
Visual Identification and Troubleshooting
Identify proper ASME B16.20 spiral wound gaskets by their distinctive outer centering ring, inner centering ring, and visible spiral winding pattern. Common installation issues include uneven compression, incorrect torque application, and mismatched flange surface finishes.
