ASME B16.5 Class150 Insert Blind Flange – Space-Saving & Easy to Install
1.Product Description
An Insert Blind Flange is a solid disc with no center hole, designed to be inserted and bolted between two standard flanges in a piping system . Its primary function is to block off sections of a pipeline . Unlike a pipe cap, a blind flange is secured with bolts, making it easy to install and remove for maintenance, inspection, or system modification . It serves as a reliable, removable closure.
The design and manufacturing of insert blind flanges are governed by various international and national standards. Key parameters include:
|
Parameter |
Details & Examples |
|---|---|
|
Pressure Ratings |
Common ratings include PN 10 and PN 16 . Standards like GB/T 4450-1995 cover marine-use flanges . |
|
Size Range |
Available in a wide range of diameters, from as small as DN 15 up to large sizes like DN 2000 or even larger . |
|
Materials |
Made from various materials including carbon steel (e.g., Q235, ASTM A105), alloy steel, stainless steel, and plastic . |
|
Standards |
Conforms to various standards such as GB/T (China), DIN (Germany), ASME (USA), and industry-specific standards like SH/T for petrochemicals . |
|
Temperature Range |
Operating temperatures can vary; for example, some are rated for temperatures up to 300 °C, while others, like spectacle blinds per DIN 86042, are used up to 120 °C . |
Insert blind flanges are critical for safety and maintenance in numerous industries:
Isolation for Maintenance and Safety: They provide a secure and sealed barrier to temporarily or permanently isolate a section of a pipeline . This allows for safe inspection, cleaning, or repair of equipment like valves, pumps, and vessels without draining the entire system . Their robust sealing performance makes them a preferred isolation method.
Pipeline Termination: Used to permanently or temporarily seal the end of a piping system .
Wide Industry Use: They are versatile components found in:
Shipbuilding: Used in various shipboard systems, with standards like GB/T 4450-1995 specifically for marine flanges .
Petrochemical & Oil Refining: Standards like SH/T3425-2011 govern their use in steel pipelines for this sector .
Power Generation: Isolate sections in boiler and steam systems to prevent leaks and ensure safety during upkeep.
Aerospace and Vacuum Systems: Used in high-specification environments, with standards available for aerospace applications and vacuum systems .
