Description
A semicircular, scored, reverse-acting rupture disc, ideal for liquid, gas, or vapor applications.
Designed for use in toxic and corrosive environments, the APX rupture disc combines the performance of Continental Disc rupture discs with materials that resist the most challenging process media. The APX continues the legacy of the flagship HPX® product with low Kr factors, high cycling capability, and the quality certifications you expect from Continental Disc Corporation.
The Continental Disc APX™ rupture disc is a semicircular scored reverse acting rupture disc that is ideal for liquid or gas/vapor applications. In terms of performance, precision, and durability, the APX rupture disc outperforms the competition. One of several benefits of the APX is the flexibility to tailor it to the demands of the customer, particularly regarding flexibility in holder materials of construction.
Designed for use in toxic and corrosive environments, the APX rupture disc combines Continental Disc’s rupture disc performance with materials that stand up to the most challenging process media. The APX continues the legacy of the flagship HPX® product with low Kr factors, high cycling, and quality certifications that you’ve come to expect from Continental Disc Corporation.
Optimum material thickness and manufacturing tooling design provide not only the full opening and accurate burst rating you expect, but also longer service life at higher operating-to-burst pressure ratios demanded by today’s process industries.
• Developed for highly toxic and/or corrosive services.
• Operating ratio capabilities of up to 95% of burst pressure to meet industry standards.
• Wide range of burst ratings from 20 to 600 psi to meet a broad range of toxic service applications.
• Standard-height, reduced-height, and custom-height holders available to accommodate piping constraints.
• Dual-disc and pre-torqued holders available to expand overpressure protection applications in toxic services.
• The rupture disc can be operated at full vacuum.
