Boiler expanders are self-feeding, parallel rolling, three expanding rolls and three flaring rolls with fixed roller length. It is particularly suitable for rolling and flaring tubes in drums, super heater and economizer header having small plug or hand hole openings.

Booster coil is a secondary ignition coil, which increases the intensity of the spark. It is a basic hot water or steam coil used to boost the temperature in a ducted HVAC system. These are available in many different sizes.

Borescope is a long, thin, rigid rod like optical device that allows an inspector to see into inaccessible areas by transmitting an image from one end of the scope to the other. Borescopes are designed to provide direct, forward oblique, right angle, and retrospective viewing of the area in question. It is used in aircraft/engine maintenance programs to reduce or eliminate the need for costly teardowns. It comes in three general types: rigid, flexible and charge-coupled devices. Rigid and fiberoptic borescopes are capable of providing access to small openings. The rigid borescopes utilize a lens train; this is called the lens optic technique.

Bottom entry mixers are designed to fit into the bottom or side of a mixing vessel. These mixers are typically used in conjunction with a slow speed anchor stirrer or scraper unit for high viscosity products. It gives high shear homogenization while the stirrer/scraper distributes the homogenized output uniformly through the vessel. It is ideal for high viscosity cosmetic, pharmaceutical, and food products. It can also be used for low viscosity products and to wet out powders.

Brake shoes are curved metal parts of a drum brake assembly that carry the friction material lining. These are the components that mount the friction material or linings that contact the drums. The shoes also provide the area to mount the backing plate. These are usually made from welded steel, although some drum brakes use aluminum shoes. The outer part is called the table or sometimes the rim and is curved to match the curvature of the drum. The brake lining is riveted or bonded to the brake shoe table. Many brake shoes have small notches or nibs along the edge of the table that bear against the backing plate and help to keep the shoe aligned in the drum. The web is the inner part of the shoe that is perpendicular to the table and to which all of the springs and other linkage parts attach.

A brake is a device, which is used for slowing or stopping the motion of a machine or vehicle, and to keep it from starting to move again. The kinetic energy lost by the moving part is usually translated to heat by friction. Alternatively, in regenerative braking, much of the energy is recovered and stored in a flywheel, capacitor or turned into alternating current by an alternator, then rectified and stored in a battery for later use. Brakes of some description are fitted to most wheeled vehicles, including automobiles of all kinds, trucks, trains, motorcycles, and bicycles. Baggage carts and shopping carts may have them for use on a moving ramp.

Brass Tube Plugs are made with a brass nut and bolt assembly. These plugs are offered in either double size (two silicone parts) or a single size (one silicone part). The single plugs are recommended for lower pressures and the doubles are for pressures between 60 psi and 150 psi.

Breather Desiccators is designed to be remotely mounted to the exterior of an equipment. It provides protection against corrosion, dampness and contamination in electronic, electrical, optical, electro-optic and telecommunications. It is a powerful adsorbing agent. The molecular sieve desiccant maintains an ultra low relative humidity for extremely sensitive applications. It is suitable for applications where equipment or enclosures are used.
