The ANSI/ASME B16.5 Class 150 Blind Flange is a standard flange used to seal pipeline ends or equipment openings, offering advantages such as complete sealing, easy installation and removal, and high adaptability.
Features of ASME B16.5 150# Blind Flange
- Standard: Complies with ANSI/ASME B16.5.
- Pressure Rating: Class 150 (maximum working pressure of 150 psi at ambient temperature).
- Type: Blind Flange.
- جنس: فولاد کربنی (مانند ASTM A105)، فولاد ضد زنگ (مانند ASTM A182)، فولاد آلیاژی (مانند ASTM A182 F11) و غیره.
- انواع چهره: صورت برجسته (RF)، صورت صاف (FF)، مفصل حلقه ای (RTJ) و غیره.
- محدوده اندازه: به طور معمول از 1/2 اینچ تا 24 اینچ.
Applications of ASME B16.5 150# Blind Flange
- Sealing Pipeline Ends: Used to seal temporarily unused pipeline ends.
- Equipment Isolation: Used to isolate equipment or pipeline systems for maintenance and inspection.
- Pressure Testing: Used for pressure testing of pipeline systems to ensure sealing.
- Preventing Media Leakage: Used to prevent media leakage or the entry of external contaminants into the system.
The ASME B16.5 150# Blind Flange is widely used in industries such as oil and gas, chemicals, and power to ensure system sealing and safety. Proper selection and use of blind flanges are key to ensuring the long-term stable operation of pipeline systems.

سوالات متداول
- The maximum working pressure of a Class 150 blind flange at ambient temperature is 150 psi. Specific pressure-temperature ratings can be found in the ANSI/ASME B16.5 standard.
- The main difference is that a blind flange has no center hole and is used to seal pipeline or equipment openings, while a regular flange is used to connect pipelines or equipment.
- Class 150 blind flanges are suitable for low-pressure systems. For high-pressure systems, blind flanges with higher pressure ratings (e.g., Class 300, Class 600) should be selected.
