Threaded companion flanges are widely used across industrial, commercial, and municipal piping systems. Selecting the right one for a specific application involves more than just choosing a pipe size. Before specifying or installing a threaded flange, engineers and procurement teams
Not every piping connection can be welded. In explosive atmospheres, remote locations, or systems requiring regular disassembly, threaded companion flanges provide an essential alternative. Standardized under ANSI/ASME B16.5 and used across oil & gas, process, and utility piping systems worldwide,
Plate flanges are cut or machined from flat steel plate rather than forged from bar or billet. They are widely used in waterworks, irrigation, selected industrial systems, utility connections, and other applications where ring-type slip-on and blind flange styles are
Plate flanges are fabricated by cutting profiles from flat carbon or stainless steel ASTM specified plate. Subsequently, they are machined to precise specifications, including bolt hole patterns and center bores. While forged flanges are formed under high pressure from round
Plate flanges are one of the most widely used connection components in piping systems, especially in waterworks, industrial processing, and utility applications. They are fabricated by cutting profiles from flat carbon or stainless steel ASTM specified plate. Subsequently, they are
If you work on water or wastewater projects, you’ve likely encountered AIS (American Iron and Steel) and BABA (Build America, Buy America). They are closely related but don’t operate the same way in practice. AIS established the baseline by requiring
The Deutsches Institut für Normung (DIN) is a leading standards organization that aligns with European and international frameworks to ensure industrial safety and quality. DIN establishes essential requirements for metric piping, specifically regarding flange materials, pressure ratings, and temperature tolerances.
Plate flanges are flanges manufactured from flat-rolled steel plate stock rather than being shaped from heated metal billets through a forging process. They are cut, machined, and drilled from plate stock for use in a wide range of piping systems.
A “plate flange” describes how a flange is manufactured (cut from plate/flat stock), not a universal dimensional standard. The actual dimensions, bolt-hole patterns, facing details, and pressure/temperature rules come from the standard you specify, such as ANSI/ASME B16.5, AWWA C207,
If you have worked around flanges long enough, you have seen it. Two different suppliers, two flanges made to the same specification, with the same dimensions, tolerances, material, and standard, and still do not look equal when they arrive. One
