ISO 7005-1 Flanges – Certified Industrial Flanges by Werner Flanges Inc.
ISO 7005-1 Flanges are industrial pipeline components used to connect pipes, valves, pumps, and other equipment in pressurized systems. Designed according to the ISO 7005-1 standard, these flanges are typically manufactured from steel and intended for general-purpose applications across industries. Werner Flanges Inc. offers precision-engineered ISO 7005-1 flanges that meet stringent international quality standards, ensuring safe and leak-proof connections even under high-pressure and high-temperature conditions.
ISO 7005-1 flanges are widely used in oil and gas, petrochemical, power generation, shipbuilding, HVAC, water treatment, and other industrial sectors. These flanges are particularly preferred in European-standardized projects or where ISO compliance is mandated. Their adaptability to different pressure ratings (PN) and facing types makes them suitable for both above-ground and underground installations.
Werner Flanges Inc. maintains a large inventory of ISO 7005-1 flanges in a variety of pressure classes including PN6, PN10, PN16, PN25, and PN40. We supply a full range of sizes, materials, and flange types—such as weld neck, slip-on, and blind flanges—with optional surface finishes and testing certifications. Custom fabrication and express shipping options are available to meet urgent project needs.
With over three decades of experience in industrial flange manufacturing, Werner Flanges Inc. is a globally trusted name among EPC contractors, OEMs, and maintenance teams. Our ISO-certified production facilities, robust quality control, and responsive customer service make us a reliable partner for ISO 7005-1 flange sourcing. Whether your requirement is for a single unit or bulk shipment, we ensure timely delivery backed by full compliance documentation.
