Blind flanges are critical components in industrial piping systems, designed to block off pipeline openings for maintenance, inspection, or future expansion. Manufactured by Hebei Jiyuan Pipeline Manufacturing Co., Ltd., these flanges combine durability, versatility, and compliance with international standards to meet the demands of diverse industries.
Product Features
Blind flanges are solid, disk-shaped components that create a secure seal in piping systems. Unlike other flanges, they lack a central hole, making them ideal for sealing valves, pressure vessels, or pipeline ends. Their design allows for easy installation and removal, facilitating frequent maintenance without compromising system integrity. Hebei Jiyuan’s blind flange products are available in multiple materials, including carbon steel (ASTM A105, P235GH) and stainless steel (ASTM A182, 304/306), ensuring resistance to corrosion, high pressure, and extreme temperatures.
These blind flange types are engineered to align with global standards such as ASME, DIN, JIS, and EN, guaranteeing compatibility across international projects. Surface coatings like black paint, galvanization, and epoxy paint further enhance their longevity in harsh environments. Whether for low-pressure noncorrosive applications or high-stakes industrial settings, Hebei Jiyuan’s blind flanges deliver reliable performance.

Application Scenarios
Blind flanges are indispensable in industries requiring secure, removable seals. For example, in oil and gas operations, they are used to isolate sections of pipelines during maintenance or testing. In power generation, they ensure leak-proof connections in high-pressure steam systems. The water treatment sector relies on blind flanges to block valves during upgrades, while shipbuilding applications benefit from their corrosion resistance in marine environments.
Hebei Jiyuan’s blind flanges are also ideal for chemical processing plants, where they prevent hazardous material leaks during system inspections. Their adaptability to ASME and DIN standards makes them suitable for global projects, while their carbon steel and stainless steel options cater to both cost-effective and high-performance needs. Whether for low-pressure or high-temperature applications, these flanges ensure operational safety and compliance.
