Exploring API 605 Standards: A Guide to Emirerri Steel's ANSI B 16.47 Series B Products

ANSI B16.47 Series B, also known as API 605, is a set of standards established by the American National Standards Institute (ANSI) and the American Petroleum Institute (API). These standards define the design, dimensions, materials, pressure ratings, and sizes for large-diameter steel flanges. API 605 flanges are commonly used in the oil and gas industry, chemical processing, and other applications requiring robust and reliable connections in high-pressure and high-temperature environments.
