Butt-Weld Flangeis a pipe fitting designed to connect pipes via welding—its neck is fused directly to the pipe end, creating a strong, leak-tight joint. It is widely used in high-pressure, high-temperature systems like oil and gas pipelines, power plant steam lines, and industrial chemical process pipes, where structural integrity under extreme conditions is non-negotiable.
A key advantage ofButt-Weld Flangelies in its superior strength and sealing reliability. The butt-weld connection distributes stress evenly across the joint, avoiding weak points found in threaded or slip-on flanges, and can withstand pressures up to 100+ MPa and temperatures over 600°C. This design also minimizes fluid turbulence at the joint, reducing erosion and extending the system’s service life.
Butt-Weld Flangefurther offers versatility and compliance. It is manufactured in various materials (carbon steel, stainless steel, alloy steel) to match pipe media—from crude oil to corrosive chemicals—and adheres to standards like ANSI B16.5 and DIN EN 1092-1. The smooth weld interface simplifies cleaning, making it suitable for hygienic applications (e.g., pharmaceutical fluid lines). Whether used in offshore rigs or refineries, it delivers stable performance for critical piping connections.
