A safety digest highlights the value of worker participation to prevent chemical incidents. Produced by the U.S. Chemical Safety Board (CSB), the digest notes that lack of worker participation was a factor in several major incidents investigated by the CSB. In each case, workers and their representatives were not engaged to help identify hazards and reduce risks.

M&J Valve Danflo is engineered to track unabated surge-wave pressure transients. The surge-relief valves can be gas loaded or pilot operated. Both types of surge-relief valves actuate in 100 msec and open in 250 msec, thus diverting the required flow quickly enough to keep the pipeline pressure well below the setpoint.

Infrared heaters are used to transfer heat through a process or to a product via radiation.

Durex Industries, Cary, Ill., is offering screw plug, flange immersion and circulation heaters with fast-turnaround shipping capabilities. Plug heaters ship in three to five days, flange heaters ship in five to seven days and circulation heaters ship in nine to 12 days, regardless if they are standard or custom-configured. In addition, there is no upcharge for customized units or non-standard configurations.

Wisconsin Oven Corp., East Troy, Wis., shipped a four-zone conveyor oven to a manufacturer in the oil and gas industry. The electrically heated oven has the capability to heat 25 parts per hour with a heating time of 48 minutes and a cooling time of 12 minutes. Each chamber in this four-zone oven has a maximum temperature rating of 752°F (400°C).

A lack of regulations governing onshore drilling safety as well as shortcomings in safety management systems and industry standards utilized by the industry are among reasons cited for a fatal gas well blowout, says the U.S. Chemical Safety Board.

Convection and conduction heaters are used in heat processing applications to create and apply heat via either a medium such as air or via direct contact.

With a firing range of 15,000 to 200,000 MBH, Model FDR(X) combines a windbox, air register, ignition assembly, fuel train, flame-safety control, combustion control, flue-gas recirculation system and forced-draft blower into a packaged unit.

Digital mass-flow controllers provide stable control of mass-flow rates of process gases. With simultaneous display of mass-flow, volumetric-flow, pressure and temperature parameters, it can be used with manufacturing, bioreactors and surface depositions, and gas-sampling activities. 

Morris L. Crafton, founder of Thermcraft Inc., Winston-Salem, N.C., died in February at the age of 93. Crafton and his wife Clara founded the oven and furnace maker Thermacraft in 1971, initially focused on making replacement heating elements for industrial and laboratory furnace applications.
