ASME B16.5 Class 300 American Standard Butt-Weld Flange is a precision-engineered pipe fitting adhering to ASME B16.5 standards and rated for Class 300 pressure (≈517 psi at 100°F), designed to create strong, leak-tight joints via butt welding. It is widely used in oil and gas midstream pipelines, petrochemical process lines, and power plant auxiliary systems, where medium-to-high pressure and dimensional consistency are critical.
A key advantage of ASME B16.5 Class 300 American Standard Butt-Weld Flange lies in its pressure rating and standardization. The Class 300 rating suits most industrial medium-pressure applications, avoiding over-engineering costs, while ASME B16.5 compliance ensures global interchangeability—simplifying cross-project procurement and maintenance. The butt-weld design also distributes stress evenly, reducing joint failure risks under pressure fluctuations.
ASME B16.5 Class 300 American Standard Butt-Weld Flange further offers material versatility and durability. It is manufactured in carbon steel (A105), stainless steel (304/316L), and alloys (A182 F91) to match media like natural gas, light crude, or steam. The weldable structure ensures a seamless connection that resists corrosion and erosion, extending service life. Whether used in U.S. refineries or international gas transmission lines, it delivers reliable, code-compliant performance for medium-pressure piping systems.
