The Kerotest MIJ Insulators bring the highest quality monolithic isolation joint manufacturing and assembly capabilities to North America. MIJ Monolithic Isolation Joints, assembled right here in the U.S., use advanced corrosion prevention technology, testing equipment, tracking procedures, materials and coatings. The quality management system of our Mansura, Louisiana facility meets the requirements of ISO 9001:2015, and now houses Kerotest’s new MIJ manufacturing operations. With this new state-of-the-art equipment and capability, our customers will benefit from short lead times, ready inventory and reduced shipping costs.

Kerotest has produced and delivered WEI insulators for more than 48 years now. That experience led us to the design and development of the MIJ Insulator – a natural progression in maintaining current standards and meeting changing industry needs in both performance and production. The Kerotest MIJ Insulator fittings are designed for the most demanding cathodic applications in new and existing natural gas and petroleum pipelines.
