ISO7005-1 Flanges and Their Joints—Circular Flanges for Pipes

ISO 7005-1 flanges and their joints-circular flanges for pipelines-are manufactured via the forging process. Forged construction ensures exceptional mechanical strength, structural integrity, and long-term reliability, with key specifications and details as follows: – Size Range : DN10 – DN3600 (Nominal Diameter, compliant with ISO international pipeline size standards) – Pressure Class : PN2.5 – PN420 (Nominal Pressure, in accordance with ISO 7005-1 pressure rating specifications) – Material Scope : Carbon steel, stainless steel (e.g., 304L, 316L, duplex grades), alloy steel (forged to meet ISO material standards, ensuring excellent corrosion resistance, pressure-bearing capacity, and temperature adaptability) – Core Advantages : Forged microstructure delivers superior sealing performance, high fatigue resistance, and global interchangeability-compatible with international industrial pipeline systems, suitable for harsh operating conditions such as high pressure, high temperature, and corrosive media. – Application Scope : Designed for pipelines transporting liquids, particulates, and gases. Widely used in chemical processing, oil refining, boiler systems, power generation, food processing, and other industrial fields requiring standardized, internationally compatible pipeline connections and pressure sealing.
