PTFE Spectacle blinds

Tank & Pipeline Ancillaries

Spectacle Blinds are simple safety devices that are installed between two pipe flanges. During normal operation, the open end is installed as a spacer to allow uninterrupted flow. To stop the flow in the pipeline, the blind end is rotated into place between the flanges. This positively isolates the downstream piping and equipment. A Spectacle Blind is generally installed as a permanent fixture.

Specifications

Material: Constructed from PTFE, known for its exceptional chemical resistance, non-stick properties, and ability to withstand high temperatures. PTFE is ideal for applications involving aggressive chemicals and corrosive environments.
Design: The figure-8 shape allows for easy switching between the blind and spacer positions. The solid plate blocks the flow completely, while the ring allows fluid to pass through.
Functionality: Spectacle blinds are inserted between flange joints in piping systems. By rotating the blind, operators can quickly change from blocking the flow to allowing it, facilitating maintenance and inspection procedures.
Versatility: Suitable for a wide range of industries, including chemical processing, pharmaceuticals, food and beverage, and water treatment. PTFE spectacle blinds can handle various fluids and gases without degradation.
Safety: Provides a secure method for isolating sections of the pipeline, ensuring the safety of personnel during maintenance and repair activities.

Advantages

Chemical Resistance: PTFE material offers superior resistance to a wide range of chemicals, making these blinds suitable for harsh environments.
Durability: PTFE spectacle blinds are highly durable and can withstand extreme temperatures and pressures, ensuring long-term performance.
Ease of Use: The design allows for quick and easy switching between open and closed positions, simplifying maintenance operations.
Cost-Effective: Provides a reliable and economical solution for pipeline isolation, reducing the need for more complex isolation methods.
