Chemical isolation systems should be deployed with vented equipment to protect both upstream process equipment and even clean air exhaust systems that return into the process. The BS&B Type IPD Chemical Isolation System provides protection to interconnected equipment in the event of an explosion. Ducting and piping connecting process equipment can propagate an explosion originating within a single piece of equipment. If unprotected, the ducting piping as well as the connected vessels and equipment are at risk. The BS&B Chemical Explosion Isolation System is designed to inject a suppression agent into ducting and piping to interrupt the transport of burning material and quench the flame front. When the sensor detects the early stages of the deflagration, not only are the main suppressing cannons activated but at the same time an isolation cannon is activated on each duct creating a chemical block on the duct and thus preventing the deflagration from moving upstream or downstream.
BS&B Safety Systems GmbH manufactures a full-line of high-quality pressure relief devices, explosion protection devices and wireless monitoring devices that are marketed throughout Germany, Europe and world markets. BS&B offers more than 75-years of leadership in the development of rupture disks, bursting discs and pressure relief devices. Its products are designed for the industrial process industries including chemical, oil and gas, pharmaceutical, biotechnology, food and beverage, and the OEM industry.
The BS&B product lineup includes:
Rupture Disks/Bursting Disks
Designed to provide reliable and accurate pressure relief at a chosen pressure and temperature, the rupture disk (bursting disc) changes from a seal to full open in an instant making it an excellent choice for both primary relief and isolation of pressure relief valves. When applied to a valve inlet, the rupture disk protects from the rigors of normal process operation by maintaining a leak tight seal. Applied to a valve outlet, a rupture disk prevents any undesirable back pressure influence and blocks relief line process materials from reaching the valve. Manufactured in nominal sizes from ¼in (6mm) to 44in (1,100mm), BS&B rupture disk technology choices meet both performance requirements and budget.
Buckling Pin Valves
An alternative to the rupture disk, the buckling pin valve provides pressure relief that meets the needs of continuous processes. The buckling pin controls valve operation and is installed externally to the process. This allows pin replacement without removing the valve from the process line, under normal circumstances. Typically applied to larger line sizes, the buckling pin valve is reset in place by one person in a few minutes compared to the hours required to replace a rupture disk or remove and retest a pressure relief valve. Manufactured in nominal sizes from 2in (50mm) to 72in (1,800mm), this technology is especially well suited to energy industry applications where fast reset of pressure relief systems is essential and to hazardous service in the process industry to achieve minimum process exposure time of personnel.
Explosion Protection Technology
BS&B 'venting' and 'suppression' technology protects low strength equipment such as dust collectors, dryers, cyclones, silos and grinding systems from the destructive effects of a deflagration. Protection of connected pneumatic systems is provided by either mechanical or chemical isolation. Hybrid applications of venting, isolation and suppression technology often provide the most cost effective protection. Comprehensive 'risk assessment' by BS&B evaluates protection strategies in line with codes and standards.
Commitment to Codes and Standards
BS&B manufacturing locations throughout the world are certified ISO 9001 with a commitment to stringent quality control systems to assure that consistent quality products are provided to the marketplace. Also, BS&B rupture disk / bursting disk technology is available certified according to the ASME Code with a "UD" stamp applied to both disk and safety head (holder) and to the European Code EN 4126-2 with a "CE" mark applied to both disk and bursting disc holder. Additional international standards such as ISO and TUV are supported. buckling pin valves are also provided with the "UD" stamp or "CE" mark, as required. The explosion protection solutions provided by BS&B follow either NFPA standards and guidelines (including NFPA 68, NFPA 69, NFPA 654) or the European ATEX directive.
From the ordering of raw materials to manufacturing, testing and final distribution, BS&B conforms with established international standards of quality. Meaning, you can rest assured knowing that any product bearing the BS&B name has passed a rigorous set of tests and meets the highest industry standards.
