In 2023, The American Water Works Association (AWWA) has issued a specification revision affecting the bolt hole diameter for 22″ Class-F flanges. This revision is applicable to Carbon Steel (AWWA C207 Class F) and Stainless Steel (AWWA C228 Class SF)
On the surface, choosing between threaded and socket weld flanges can seem like a minor detail. In reality, the sealing performance difference between the two is meaningful. This guide breaks down how each connection works, where each performs well, where
Threaded pipe 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 pipe flange, engineers and procurement
Domestic ASTM A36 is one of the most commonly specified carbon steel grades in American manufacturing. The combination of low carbon content, reliable weldability, and domestic availability makes it a practical choice across a wide range of industrial applications, which
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
