Leak Prevention Space Saving Blind flange ASMEB16.5 Class150

1.Product Description

A blind flange, also known as a blind flange, is essentially a solid disk with no center hole, designed to be bolted onto a pipe or vessel flange . Its primary function is to block off sections of a piping system. Unlike a pipe cap, a blind flange is secured with bolts, making it easy to install and remove for maintenance or system modification . There is also a special type called a spectacle blind flange (or figure-8 blind), which has a solid end for isolation and a ring end for flow, allowing for easy switching between operational and isolated states .

2.Key Product Parameters

The design and manufacturing of blind flanges are governed by various international standards to ensure safety and compatibility. Key parameters include:

3.Product Applications

Blind flanges are critical for safety and maintenance in numerous industries:

• Isolation for Maintenance: They provide a reliable, sealed barrier to temporarily 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 systems like fuel lines, ballast water, and ventilation .

  • 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 .

  • Water Treatment & Public Utilities: Employed in municipal water supply and wastewater treatment plants to manage flow and facilitate equipment servicing .

  • Other Sectors: Also common in paper manufacturing, mining, pharmaceuticals, and food processing .
