Product Introduction


A flat-welded flange is a widely used pipe connection component designed to be welded directly onto the end of a pipe, providing a reliable and economical sealing solution for various piping systems. It features a flat sealing surface and simple structural design, which makes installation easier compared to other flange types. Flat-welded flanges are commonly applied in low- to medium-pressure and temperature pipelines, such as water supply systems, drainage lines, chemical processing, petroleum transport, power generation, and general industrial piping.
These flanges are typically manufactured from carbon steel, stainless steel, alloy steel, or other engineering metals, allowing them to meet different mechanical strength and corrosion resistance requirements. The welding process ensures stable alignment between the pipe and flange, reducing stress concentration during operation. Flat-welded flanges are compatible with standard gasket materials and bolt assemblies, enabling secure sealing performance and convenient maintenance. With standardized dimensions, good interchangeability, and cost-effective production, flat-welded flanges remain a practical choice for industrial piping installations worldwide.
