Product Description

Key Features

Premium Casting Material Manufactured via precision casting using high-strength alloy steel or ductile iron, offering excellent mechanical strength, toughness and resistance to impact, extrusion and fatigue under downhole conditions.

Stable Centralizing & Protection Rigid one-piece body provides reliable centering; optimized profile avoids scraping tubing or wellbore, effectively eliminating eccentric wear and extending cable service life.

Anti-Slip & Anti-Rotation Equipped with built-in locking structure and friction pads to firmly grip cables and tubing, preventing axial slippage and circumferential rotation in dynamic working conditions.

Corrosion & Temperature Resistance Surface treated with anti-corrosion coating; suitable for high-temperature, high-pressure and corrosive downhole environments, with long service life.

Easy Installation & Wide Compatibility Simplified clamping/split mounting design for fast installation; compatible with API standard tubing (2-3/8" to 7") and various round/flat cables. Custom sizes available.

Frequently Asked Questions

What materials are used for these cable protectors?

Our protectors are manufactured using high-strength alloy steel or ductile iron through a precision casting process to ensure maximum durability in downhole environments.

Are these compatible with standard API tubing sizes?

Yes, they are designed to be compatible with API standard tubing ranging from 2-3/8" to 7". Custom sizes are also available upon request.

How do they prevent the cable from slipping?

Each unit is equipped with a built-in locking structure and specialized friction pads that provide a firm grip on both the cables and the tubing, preventing any axial or circumferential movement.

Can these be used in horizontal or deviated wells?

Absolutely. The rigid one-piece body design is specifically optimized for ESP cable protection in vertical, deviated, and horizontal well configurations.

What kind of surface protection is applied?

The protectors undergo an anti-corrosion surface treatment, making them highly resistant to high temperatures, high pressure, and corrosive downhole fluids.
