Blind flanges are essential components in industrial piping systems, designed to block off pipelines, valves, or pressure vessels. As a critical part of blind flange solutions, HEBEI JIUYUAN PIPELINE MANUFACTURING CO.,LTD. offers high-quality products tailored for diverse industrial applications. This article explores the features, technical specifications, application scenarios, and company background of blind flanges, ensuring compliance with international standards and providing insights into their practical use.
Product Features of Blind Flanges
Blind flanges are solid disks engineered to seal the end of a piping system, valve, or pressure vessel. Their design emphasizes ease of installation and removal, making them ideal for systems requiring frequent inspection or maintenance. Key features include:
- Material Variety: Available in carbon steel (ASTM A105, P235GH, P245GH, etc.), stainless steel (ASTM A182, 304, 306), and alloy steel, ensuring versatility across different environments.
- Pressure Ratings: Compatible with standards such as ANSI/ASME, DIN, JIS, and others, supporting pressure ratings from PN6 to PN40 and Class150 to Class2500.
- Surface Coatings: Options like black paint, galvanization, grease, and epoxy paint enhance corrosion resistance and durability.
- International Standards Compliance: Adherence to ASME, EN, JIS, DIN, BS, and other global standards ensures compatibility with diverse industrial systems.

Installation Guide for Blind Flanges
Proper installation ensures optimal performance and safety. Follow these steps:
- Preparation: Clean flange faces and gaskets to remove debris. Use a gasket compatible with the system’s fluid and pressure.
- Alignment: Match bolt holes of the blind flange and mating flange. Insert bolts and tighten in a crisscross pattern to ensure even pressure.
- Torque Application: Use a torque wrench to apply specified torque values, following manufacturer guidelines.
- Testing: Conduct pressure tests to verify leak-proof sealing before system operation.
