JIS 10K Steel Flanges manufactured by Jiangyin Zhonghai Precision Machinery Co., Ltd. are engineered in strict accordance with the JIS B2220 standard. Designed for exceptional performance in medium-pressure environments, our 10K flanges offer more than just standard interchangeability. Through our integrated forging and heat treatment processes, we optimize the metallurgical structure of each component, ensuring superior tensile strength and long-term sealing stability.

With a production range from 1/2" to 60", Zhonghai delivers high-quality SOP, SOH, and Blind flanges. We also specialize in large-scale, non-standard JIS components with diameters up to 4 meters and individual weights up to 10 tons.

Core Advantages
·Certified Compliance: ISO 9001 certified with PED (Pressure Equipment Directive) and TS (Special Equipment License) qualifications, ensuring every 10K flange meets global safety and regulatory requirements.
·In-house Production Control: Our facility features a complete production line, including forging, heating, CNC turning, drilling, and testing. This end-to-end control eliminates quality inconsistencies.
·Deep Customization Capability: We support bespoke manufacturing based on drawings. Simply provide your dimensions (OD, ID, thickness, bolt circle, etc.), and our experts will provide a rapid technical assessment and quotation.
·Scalable Delivery: From small-batch prototypes to mass production, our internal forging capacity significantly reduces lead times for complex or non-standard orders.

Key Features
·High-Precision Machining: Utilizing CNC lathes for face finishing to ensure flatness and roughness levels strictly comply with JIS B2220, minimizing the risk of system leaks.
·Superior Material Density: Unlike simple plate-cut products, our 10K flanges are primarily forged to eliminate internal defects and enhance the pressure-bearing safety factor.
·Rigorous Quality Inspection: An independent QA department oversees dimensional verification and NDT (UT/MT) as required. All products are supplied with full Material Test Certificates (MTC).
·Versatile Surface Finishing: Options include anti-rust oil, painting, electro-galvanizing, or hot-dip galvanizing to suit various corrosive environments.

Applications
Zhonghai JIS 10K Flanges are the preferred choice for:
·Japanese Equipment OEM: Perfect compatibility with imported Japanese machinery, pumps, and compressors.
·Marine & Offshore: Adhering to JIS piping standards commonly used in international shipbuilding.
·Industrial Fluid Control: Low-to-medium pressure pipelines in chemical, oil, and gas sectors.
·Public Utilities: Municipal water supply, HVAC systems, and fire protection networks.
