[Xi’an, China – July 10th, 2025] — To support the safe and efficient operation of cathodic protection (CP) systems, KIG Tech provides high-quality Insulating Flange Gasket Kits and Monolithic Isolation Joints — two essential solutions designed to achieve effective electrical isolation in pipeline networks, especially in CP-zoned areas.

By preventing unwanted current flow and minimizing stray current interference, these components help improve the efficiency of cathodic protection systems and extend the life of critical pipeline infrastructure.

Product Overview

1. Insulating Flange Gasket Kits

Used in flanged joints, these kits include insulating gaskets, sleeves, and washers to block electrical conductivity across connected pipelines.

• Available in Type D, Type E (full-face), and Type F (ring) designs
• Suitable for oil, gas, water, and chemical pipelines
• Designed to withstand pressure and temperature variations
• Prevents galvanic corrosion between dissimilar metals

2. Monolithic Isolation Joints

Factory-assembled and permanently sealed, these joints ensure long-lasting, maintenance-free electrical separation.
• Constructed with high-strength dielectric materials
• Electrical resistance ≥ 10 MΩ
• Tested to 3,000V and pressure-rated
• Ideal for buried or subsea pipelines
• Eliminates field installation errors

Why Electrical Isolation Matters in CP Systems

Electrical isolation plays a vital role in cathodic protection performance. It helps:

• Prevent stray current corrosion
• Divide CP zones for accurate monitoring and current control
• Reduce risks of interference and overprotection
• Extend the lifespan of pipeline assets
• Improve operational safety at valve stations, terminals, and transitions

KIG Tech’s isolation solutions are built to international quality standards and engineered for reliable performance in challenging environments.

Typical Applications

• Valve stations and pipeline junctions
• Transition points between different metal pipelines
• Cathodic protection zone boundaries
• Underground and subsea pipelines
• Areas exposed to stray currents or grounding networks
