Bursting discs and holders are crucial components in a wide array of pressure and vacuum-related operations, playing a pivotal role in ensuring system integrity and safety under varying operational conditions. These discs, often paired with a holder, are engineered to rupture at a predetermined pressure or vacuum, allowing for immediate pressure relief during critical operations. This functionality is key not only for maintaining internal pressure within safe limits but also for preventing potential damage to system components and mitigating the risk of operational failure.
Moreover, bursting discs play a significant part when pressure adjustment is required due to changes in system or environmental conditions. By offering this dual functionality, bursting discs contribute substantially to the longevity and reliability of various systems, acting as a protective shield against unwanted pressure changes that could otherwise jeopardise both the system’s integrity and the safety of personnel.
Bursting discs and holders, due to their economical, compact, maintenance-free, and bubble-tight characteristics, are a practical and reliable choice for managing your system’s pressure needs. We also offer a selection of accessories to optimise the performance of your bursting disc assembly under different environments. At Assentech Sales Limited, our wide range of holder types, styles, and materials are designed to meet your unique requirements and provide the utmost safety and efficiency.
Types of Bursting Discs we Supply
- Reverse-Acting: Our bursting disc functions optimally in situations where pressure instabilities in the dome lead to its reversal or buckling. Compared to forward-acting designs, it offers a longer cycle life due to the compressive nature of the stresses in reverse-acting discs, which do not promote crack propagation. To ensure stability, the dome is supported on the outlet side, preventing premature movement prior to reversal. Scoring or cutting techniques are employed to facilitate opening after this reversal. The opening technique employed correlates with the energy present during reversal, with vapour reversal being significantly more energetic than liquid reversal.
- Forward-Acting: Functions can be compromised when the most vulnerable part of the disc surpasses its tensile strength. This is because, at higher operating ratios, these functions generally have a limited fatigue life. The primary reason behind this finite life is the tensile nature of the stresses they encounter. Additionally, their capability to withstand vacuum or back pressure is contingent on several factors. These include the inlet diameter that supports the dome, the prominence of the bulge, the material’s thickness, and sometimes, the incorporation of additional vacuum support.
Compliance with International Standards
Our products adhere to leading international standards for pressure relief. At the primary level, they are compliant with EN ISO 4126-2 CE and ASME XIII(UD). Beyond these benchmarks, we abide by varying international standards, highlighting our steadfast commitment to ISO9001. Moreover, we have ensured regional compliance through certifications such as the KOSHA, Canadian Registration Number (CRN), China Safety Notice, Stoomwezen, and TUV. These certifications not only reinforce our dedication to safety but also signify our aim to meet the highest quality standards across the globe.
