Vivid Steel Engg Co. is one of leading Supplier & Exporter of Flange Bleed Valve in India, Mumbai. There is a lot of misunderstanding surrounding the term double block-and-bleed (DBB) as used to describe valve functionality. It seems almost every valve buyer and manufacturer has a different idea of what the term means for valve selection, which can result in the wrong specifications or valve type. Some of this confusion in the oil and gas industry stems from the fact that there are two credible sources that define the term differently.

There are two entities in the United States that define DBB – the American Petroleum Institute (API) and the Occupational Safety and Health Administration (OSHA). API is a trade organization that acts as an advocate as well as researcher for America’s oil and natural gas industry, outlining many industry guidelines for safe operation.
