Flowline Insulating Nipples

Enhancing Cathodic Protection

SKU: RICE® FLOWINE INSULATING NIPPLES

Over the past 40+ years, Rice Flowline Insulating Nipples have become an industry standard based on their proven performance, rugged construction and ease of installation.

They isolate sections of a pipeline to improve the effectiveness of cathodic protection systems. Long path insulating nipples provide unique current control by separating pipework into distinct zones and effectively eliminating long-line currents. Optimum cathodic protection can be achieved for each section of pipeline while maximizing savings and minimizing costs.
