AI Technical Summary

Technical Problem

Existing tubular threaded components face issues with abrasion of protective coatings due to solid particles, such as mill scale and corundum, infiltrating from within, leading to degradation of functional surfaces and threads, and traditional seals fail to effectively block these particles while also causing loosening and increased installation/uninstallation difficulties.

Method used

A tubular threaded protector with an external axial seal positioned to block solid particles, anchored by a housing or joint support, ensuring the seal remains in contact with the internal wall to prevent particle infiltration and enhance locking, thereby preserving coatings and reducing loosening.

Benefits of technology

The solution effectively prevents degradation of functional surfaces and threads by blocking solid particles, maintains seal integrity, and simplifies installation/uninstallation by reducing mechanical and thermal stress-induced loosening.
