The EN1092-1 Type 01 Flange (Plate Flange) is a critical piping component designed according to the European Committee for Standardization (CEN). Jiangyin Zhonghai Precision Machinery Co., Ltd. leverages its extensive forging heritage and precision machining technology to produce Type 01 flanges that not only fully comply with EN1092-1 but also offer superior material density and mechanical performance.

Utilizing our in-house forging, heat treatment, and CNC turning production lines, we provide Type 01 flanges ranging from DN15 to DN1500, with extreme capabilities for oversized flanges up to 4 meters in diameter. Whether for standard engineering procurement or bespoke requirements based on specific blueprints, Zhonghai delivers reliable, PED-certified solutions.

Core Advantages
·Certified Quality Excellence: ISO 9001 certified with PED (Pressure Equipment Directive) and TS (Special Equipment License) qualifications, ensuring safety in pressurized environments.
·Integrated Manufacturing: Our full-process production—from raw forging and machining to heat treatment—eliminates subcontracting risks and guarantees consistent precision and lead times.
·Powerful Customization: Beyond standard specifications, we offer "Custom Machining by Drawing." Provide us with your dimensions (OD, ID, thickness, bolt circle, material), and we will provide a rapid assessment and quote.
·Independent Quality Assurance: Our specialized QA department ensures all processes align with EN, ASTM/ASME, and API standards, providing full traceability for every component.

Product Features
·Superior Craftsmanship: Available in forged or high-precision cut options. Forged flanges maintain continuous metal grain flow, offering higher strength for demanding industrial service.
·High Precision Fit: CNC turning and drilling ensure that face symmetry and bolt hole positioning fall within strict tolerances, facilitating easy on-site installation.
·Wide Pressure Range: Covering ratings from PN2.5 to PN100, suitable for various pipeline diameters and pressure conditions.
·Durable Surface Treatments: Options include anti-rust oil, black/yellow paint, electro-galvanized, or hot-dip galvanized finishes to meet specific corrosion resistance needs.

Applications
·Industrial Piping: Widely used in chemical processing, water treatment, heating, and general industrial networks.
·Equipment Interfaces: Serving as critical interfaces for pumps, valves, and pressure vessel tanks.
·Large-scale Infrastructure: Municipal water supply/drainage, desulfurization projects, and auxiliary mechanical parts.
·Export Projects: Designed to European standards, making them the preferred choice for international engineering and trade.
