Dual String Protector

Dual String Protector
Product description
Protectors are designed to protect all control lines and cables along the full length of the production string, reducing the risk of damage to cables, control lines, or flatpacks. PDT’s Protector portfolio includes clamping and cable protection solutions to protect cables from lateral, axial, and rotational loading in downhole applications. In addition to our standard cross-coupling range, PDT designs application-specific solutions for demanding situations.

 

Application 

Dual string protectors are used when completions require two production strings. Production tubing strings are typically different sizes.
The centralizer is mounted over the primary production string connection, allowing the secondary string to move freely.
