Steel Plate Flange is a pipe connection component manufactured by cutting and machining high-quality steel plates. It is widely used in industries such as petroleum, chemical engineering, power generation, shipbuilding, water supply and drainage, and mechanical manufacturing. Its primary function is to provide a reliable connection between pipes, valves, pumps, and equipment, facilitating system installation, disassembly, and maintenance.

Introduction
Steel plate flanges are typically manufactured from carbon steel, stainless steel, or alloy steel, and feature a simple structure, high strength, excellent load-bearing capacity, and stable sealing performance. The products can be designed and manufactured according to international or industry standards (such as ANSI, ASME, DIN, EN, GB, etc.) to meet the requirements of different working conditions, and are suitable for medium-low pressure and some high-pressure applications.
When used in conjunction with gaskets and fasteners, steel plate flanges effectively prevent media leakage, ensuring the long-term, safe, and stable operation of pipeline systems.
