Rishabh Industries welcomes enquiries for premium spectacle blind flanges for industrial piping projects, maintenance requirements, and plant procurement. Selecting the correct spectacle blind involves matching its material, dimensions, pressure class, and facing to the operating conditions and mating flanges.
For engineers, contractors, and purchase teams, a clearly specified spectacle blind helps simplify procurement and supports dependable pipeline isolation.
A spectacle blind flange, also called a figure-eight blind or spectacle blank, combines a solid disc and an open ring connected by a web. The solid section provides a physical barrier, while the open section allows flow through the connection. ASME describes this arrangement in its line blanks standard.
- Solid section: Used when the piping arrangement requires physical isolation.
- Open section: Maintains an open flow passage when positioned between the flanges.
- Connected construction: Keeps the blank and spacer together as one assembly.
- Planned repositioning: Requires shutdown, depressurisation, and the applicable site isolation procedure.
Industrial Applications
Spectacle blinds can serve piping systems that require a physical barrier during planned isolation. Suitability depends on the specific service and engineering requirements.
- Oil and gas facilities: Isolation arrangements for selected process lines.
- Chemical plants: Piping carrying compatible chemicals and process fluids.
- Petrochemical units: Maintenance and equipment isolation points.
- Power plants: Suitable utility and process piping connections.
- Industrial processing facilities: Planned shutdown and maintenance applications.

Frequently Asked Questions
Q1: What does a spectacle blind flange do?
A1: It provides either a physical flow barrier or an open passage, depending on which section is installed.
Q2: Is a spectacle blind the same as a blind flange?
A2: No. A spectacle blind fits between mating flanges; a blind flange closes a flanged connection.
Q3: Which material should I select?
A3: Select the material according to fluid compatibility, temperature, pressure, and the project piping specification.
Q4: Can I reposition it while the pipeline operates?
A4: Repositioning requires shutdown, depressurisation, and compliance with the site’s approved isolation procedure.
Q5: What details are needed for a quotation?
A5: Share size, pressure class, material grade, facing, standard, quantity, delivery location, and any drawings.
Q6: How do I confirm product suitability?
A6: Compare the offered specifications and documentation with your approved engineering and procurement requirements.
