Sustainability Focus

From the commencement of product development activity, the LSR rupture disk was created with a strong focus on sustainability. The design brief was to minimize the amount of raw material required while using processes that avoid the consumption of water and use the least amount of energy. Key sustainability points for the LSR rupture disk, the safety head in which it is typically used, and the facility in which it is produced are as follows;

  • Single piece construction, minimizing product material content and end of life material disposal.
  • Compatible with SRI-7RS / SRI-7RS-TR safety heads which are designed with reduced material content as a result of their patented casting based design.
  • Reduced product mass (LSR rupture disk and SRI-7RS series safety heads) which minimizes carbon footprint of product transportation activity as well as providing direct benefit with respect to shipping fees charged by weight.
  • No water consumed in the LSR rupture disk manufacturing process
  • Manufactured in a facility with ISO14001-2015 environmental management certification.
  • LSR rupture disks are individually packaged for protection in recyclable cardboard cartons marked with clear disposal identification for the user to follow.

Accessories

BS&B supplies many of the accessories required to safely and conveniently install our overpressure relief devices and complementary products. Through our professional team and global network of sales engineers and procurement personnel, we are able to provide the highest quality accessory products to meet your installation requirements.

Saf-T-Change Quick Disk Replacement (QDR)

After activation, the replacement disk is quickly slid into place. Saving hours of lost production due to blown rupture disks.

Tell-Tale Assemblies & Excess Flow Valves/Gauges

A gauge tap in the outlet flange of the safety head may be considered when the safety head is installed in a vertical position.

Spare Safety Heads & Cap Screws

Jackscrews

When activated, the jackscrews effectively separate the flanges, providing adequate clearance to remove or insert a safety head and external gaskets.

Lifting Lug Eye Bolts

Eye bolts are recommended when weight and/or accessibility is a factor in lifting safety heads.

Baffle Plate

When a safety head is free-vented to atmosphere, a baffle plate may be considered to disperse overpressure and absorb recoil.
