Blind Raised Face Flanges

New Era Pipes and Fittings’ Blind Raised Face Flanges Manufacturer delivers a dependable sealing solution for piping systems that require secure closure. These flanges are designed to have a slightly raised sealing surface so that gaskets are compressed uniformly and a pressure-tight joint is formed. They are made of high carbon steel, stainless steel, and alloy grades and can be used in oil and gas, chemical plants, water treatment, and power generation, where the restriction of flow to allow inspection or future growth is important. They have a strong construction and accept the demanding service with their specific size and shape.


In industries that have found trusted components using B2B services, Blind Raised Face Flanges are provided in different sizes, pressure classes, and finishes in accordance with the ASME, ANSI, and DIN standards. One of the main sub-products in this line is the Spectacle Blind Flange, which is used on systems that require periodic isolation of the line and easy visual verification of the open or closed position. Custom flange drilling patterns, corrosive-properties coating, and full-mill certifications can be ordered on each flange, guaranteeing the buyer will obtain products that will fit easily into the existing pipelines and comply with the project and requirement specifications.


Type of Sub-products

  • Spectacle Blind Flange
    Spectacle Blind Flange

    Spectacle Blind Flange

    It consists of a solid blind plate and an open spacer connected by a tie bar. By rotating the assembly, operators can alternate between blocking and allowing flow, perfect for systems requiring frequent line isolation or inspection without removing the flange entirely.

  • High Pressure Blind Raised Face Flange
    High Pressure Blind Raised Face Flange

    High Pressure Blind Raised Face Flange

    Built for pressure classes up to 2500, these flanges feature heavier sections and robust metallurgy to withstand severe pressure and temperature. Ideal for steam lines, superheated service, and critical process piping.

  • Threaded Blind Raised Face Flange
    Threaded Blind Raised Face Flange

    Threaded Blind Raised Face Flange

    Combines a threaded bore with a blind face, allowing closure of threaded piping without welding. It is frequently used in low pressure, non critical services or where welding is impractical.


Frequently Asked Questions

What materials are used to manufacture Blind Raised Face Flanges?

These flanges are manufactured from a wide range of materials to suit different industries and environments. Common materials include carbon steel (ASTM A105), stainless steel (304, 316, 321), alloy steel, duplex, super duplex, and nickel alloys. The choice of material depends on factors like operating temperature, fluid composition, and pressure rating. For corrosive or high stress environments, stainless steel and special alloys are preferred.

What standards do Blind Raised Face Flanges conform to?

Blind Raised Face Flanges are manufactured in strict compliance with international standards, including ASME B16.5, ASME B16.47, ANSI, DIN, and EN standards. These standards govern dimensions, pressure ratings, tolerances, and material requirements, ensuring global compatibility. Compliance guarantees that the flanges are safe, reliable, and interchangeable with equipment across different regions and industries.

What is a Spectacle Blind Flange and how is it related?

A Spectacle Blind Flange is essentially a pair of metal disks joined by a web—one solid (to block flow) and one with a bore (to allow flow). It provides a quick visual indication of whether a line is open or closed. Spectacle blinds are often used alongside Blind Raised Face Flanges in systems that require frequent flow isolation for maintenance or operational switching.
