Product catalog summary
Overview: The document outlines specifications and guidelines for Saf-T-Graf graphite disks used in safety systems to prevent overpressure. These disks are impermeable to gases and fluids, providing excellent sealing and corrosion resistance.
Armor: Armor is recommended for all graphite disks to enhance safety and prevent breakage, especially for disks with burst pressures over 150 psig or for ANSI Class 300/600 flanges. Options include carbon steel or stainless steel armor.
Stock and Specifications: BS&B offers monobloc disks in sizes from 25 to 200 mm with burst pressures from 10 to 150 psig, compatible with various flange ratings (ANSI, DIN, JIS, BS, AFNOR).
Gaskets and Sensors: Standard gaskets are made from Garlock® or Klinger®-Sil, with optional materials like GRAFOIL®, Neoprene, and PTFE. A Graphite Alert Sensor (GASTM) is available for burst detection.
Operating Conditions: Disks can operate at up to 80% of their burst pressure in static environments and are suitable for both gas and liquid services, resisting full vacuum with appropriate support.
Temperature and Corrosion Resistance: Disks withstand temperatures up to 205°C (400°F) and are corrosion-resistant except against free fluorine. An optional PTFE coating reduces product build-up.
Models and Applications: Various models are available, including monobloc and inverted monobloc, with liners for enhanced corrosion resistance. Vacuum supports are necessary for certain conditions, and armoring is advised for added safety.
Venting Capacities: Venting capacities are calculated based on ASME standards, with adjustments for vacuum support. Detailed venting capacity charts are provided for different disk sizes and conditions.
Ordering and Customization: Customers must specify flange ratings and gasket materials when ordering. Custom burst pressures and temperatures can be accommodated, with testing conducted at specified conditions.
Conclusion: Saf-T-Graf graphite disks offer reliable overpressure protection with customizable options for various industrial applications. Proper installation and specification are crucial for optimal performance.
Marked Burst Pressure Tolerance: Tolerances vary based on pressure levels, with specific examples provided. For reduced tolerances, contact BS&B Safety Systems.
Contact Information: Contact details for BS&B Safety Systems in the USA, Ireland, and the UK are provided for inquiries and support.
Additional Information: Product specifications are subject to change without notice. Questions regarding product selection should be directed to BS&B Safety Systems. All sales are subject to standard terms and conditions.

Armor Armor is recommended for all graphite disks for added safety, easier installation and elimination of breakage during installation. Armor reduces the possibility of a premature burst due to uneven or excessive torqueing of the flange studs. Armor is standard on disks with burst pressures in excess of 150 psig or to fit ANSI Class 300/600 flanges. Carbon steel armor is standard with 304/316 Stainless Steel as an option.
