Carbon steel flanges are among the most widely used pipe connection components in industrial infrastructure. They are reliable, cost-effective, and available in a range of grades and configurations. They are also able to match nearly any service condition. This guide
Selecting a carbon steel flange grade is one of the most important decisions in industrial piping procurement. The grade determines whether a flange can handle the system’s pressure, how it performs at operating temperature, and how it aligns with specific
ASTM A105 forged carbon steel flanges are the industry standard for pressure-rated piping across process, power, and oil and gas applications. A105 grade delivers the grain structure and mechanical properties required for moderate and high-pressure service. This material is referenced
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
