Bolt Hole Spiral Wound Gaskets are engineered for specialized flange connections where accurate bolt alignment is essential. The integrated bolt holes allow the gasket to be securely positioned during installation, reducing assembly time and ensuring proper alignment with mating flanges.
These gaskets are widely used in shell-and-tube heat exchangers, pressure vessels, condensers, reactors, and other custom equipment where standard spiral wound gaskets cannot meet the required geometry.
Ferrobend manufactures Bolt Hole Spiral Wound Gaskets according to customer drawings and application requirements using premium metallic winding materials and high-performance fillers. Custom dimensions, bolt hole patterns, and material combinations are available for demanding industrial services.
Ferrobend Bolt Hole Spiral Wound Gaskets are specially engineered for equipment requiring precise bolt alignment, custom dimensions, and reliable sealing under demanding industrial operating conditions.
The sealing element consists of precision-formed metallic winding combined with soft filler material to provide excellent resilience, recovery, and leak-tight sealing.
Accurately machined bolt holes ensure precise positioning during assembly, making installation faster and eliminating gasket movement.
Manufactured according to customer drawings with various shapes, bolt patterns, and dimensions for specialized equipment.
Designed to maintain dependable sealing performance under thermal cycling, pressure fluctuations, and demanding industrial environments.
