Custom Engineered Products

Solutions for Original Equipment Manufacturers (OEM), Aerospace and Energy IndustriesBS&B fast tracks customer projects by the e!cient use

of standard building blocks of rupture disk technology.

Many custom engineered product solutions are in

the form of an assembly that permanently combines

the rupture disk and holder device, ready for use.

Whether created by welding, screw thread connection

or custom #tting, a rupture disk assembly provides

the highest performance at the best cost. BS&B will

help you de#ne your rupture disk assembly needs

whether for a single custom designed component or

for thousands of competitively priced units. Our design

and manufacturing experience is put to work to meet

your challenge.

CapabilitiesAt the heart of our custom engineered products are a proven family of rupture disk designs, developed to achieve the wide range of burst pressures and to support the operating conditions demanded by the

OEM, aerospace and energy industries.

Materials

Inconel®, stainless steel and nickel are the most widely employed materials for custom engineered rupture disk products, and Inconel® is o%en favored for the stability of burst pressure over a wide range of temperature that it can uniquely provide. Holder components made from brass or stainless steel are most typically selected by customers. A considerable percentage of BS&B’s product output is manufactured from custom materials. Please ask us if the material you wish to use

is not listed above.

Quality AssuranceAll BS&B custom engineered products are manufactured and tested within ISO 9001 certi#ed facilities. Depending upon the industry that we are supporting, additional standards are met, including:

Aerospace, AS9100

Automotive TS16949

Nuclear ASME section III

Pressure vessels ASME code stamp and European Pressure

Equipment Directive

CE marked

Commitment to ExcellenceWhile BS&B’s products are o%en small in size, their contribution to safety and science ranges from space programs past and present, to vehicle protection systems, and the safety of the energy industry from exploration of fossil fuels to renewable power systems. Whether providing a single custom engineered product, building a few hundred simple threaded assemblies or embarking upon a journey to supply millions of items, the commitment to innovation and excellence is re3ected in our

people and our products.

$e starting point for all custom engineered pressure relief products is to de#ne the following parameters:

Burst pressure

Operating pressure and 3uctuations

Operating temperature and 3uctuations

Required relief area / opening area

Preferred materials

Mounting dimensions or design footprint

With BS&B’s wide range of rupture disk technology, there are typically several design and performance options available. Our experts are on hand to assist with the best #t among

performance, timing and budget considerations.

BS&B welded assemblies are used in a multitude of industries where design engineers specify customized overpressure relief solutions to meet required footprints. BS&B manufactures welded assemblies using a variety of rupture disks, outlined in this section, and integrates the disks with customized holders unique to the application. Advantages of BS&B’s welded assemblies include the following:

BS&B Extruders

Ensures accurate burst pressure

Can be con#gured for no axial clearance

Can be con#gured for one way installation

Can be con#gured with weld preparations

Unending variety of end connections

Can be con#gured for tight #t installations

Reduce weight for aerospace / defense

3ight programs

$e Extruder rupture disk is a 3ush-mounted welded disk prohibiting product build-up on rupture disks. Designed for protection and relief of excess pressure in plastics and processing equipment, these units are designed to #t hole-in-vessel wall with the rupture disk mounted 3ush with interior wall. Typical applications include polyethylene manufacturing equipment and plastic extruder barrels.
