Paddle Spacer Paddle Spacer
A matching disc with an open bore that maintains unrestricted flow when the line is in service. It mirrors the dimensions and bolt pattern of the paddle blind, simplifying interchange.

Spectacle Blind Flange Spectacle Blind Flange
A combined unit containing both the paddle blind and paddle spacer joined by a connecting web. Rotates easily between “open” and “closed” positions for quick status changes and clear visual confirmation.

Frequently Asked Questions
What are Paddle and Spacer Flanges?
Paddle and Spacer Flanges are single piece line isolation tools used in piping systems to either block flow (paddle blind) or maintain flow (paddle spacer) without dismantling the entire assembly. Cut from high strength carbon steel, stainless steel, or alloy plates, these flanges are inserted between two pipeline flanges and bolted in place. They are especially valuable in oil & gas, chemical plants, refineries, and water treatment facilities, where quick and reliable isolation is required for inspection, repair, or system modification.
Where are Paddle and Spacer Flanges commonly used?
They are heavily deployed in refineries, petrochemical plants, offshore rigs, LNG terminals, chemical processing, pulp & paper, and power generation facilities. Any environment that requires frequent pipeline isolation for safety, testing, or changeover benefits from their simplicity and robust sealing capability.
What standards and certifications apply to Paddle and Spacer Flanges?
They are governed primarily by ASME B16.48 (Line Blanks), which specifies dimensions, tolerances, and marking. Buyers often request EN 10204 3.1/3.2 Material Test Certificates, PMI (Positive Material Identification), and third party inspections (Lloyd’s, DNV, BV) for critical service. Certification ensures full traceability and compliance with global project requirements.
