Cross Coupling cable Protector for oil parts
Our cross coupling cable protector is a professional downhole accessory specially developed for oil and gas well completion operations. It is mainly used to protect ESP power cables, control lines, chemical injection lines and umbilical cables at tubing coupling joints. When running, pulling and tripping tubing strings in the wellbore, cables are prone to severe friction, extrusion and impact damage at the convex coupling positions. This cable protector tightly locks and wraps cables to isolate direct contact between cables and tubing couplings, effectively eliminating cable breakage, insulation peeling and leakage failures caused by long-term friction, greatly improving the safety and service life of downhole cable systems.
We adopt precision investment casting technology to produce cross coupling cable protectors, with optional materials including 42CrMo alloy steel, carbon steel and stainless steel according to different downhole working conditions. All products comply with oilfield API standards, with stable structural strength, excellent abrasion resistance and corrosion resistance, adapting to high temperature, high pressure, brine and other harsh downhole environments of onshore and offshore oil wells. Custom sizes and structural designs are supported to match various specification tubing couplings.
Core Structural & Performance Advantages
- Reliable Clamping Structure Split two-piece design with matched locking buckles and fastening bolts. After installation, it can firmly fix the protector on the tubing coupling without loose sliding during pipe string lifting and lowering. The inner arc fits closely with the outer wall of the coupling, providing stable positioning without offset.
- Effective Cable Protection The inner reserved wire groove perfectly accommodates multiple groups of cables, forming an isolation buffer layer between cables and metal couplings. It avoids sharp metal edges scraping cable outer jackets, and buffers external impact and extrusion force to prevent cable insulation damage.
- Superior Material Durability
- Alloy steel version: High tensile strength, strong impact resistance, suitable for deep wells, heavy pipe strings and high-friction wellbores; can be quenched and tempered for higher hardness and wear resistance.
- Stainless steel version: Outstanding anti-corrosion performance, ideal for high-salinity, corrosive formation water and offshore oil wells.
- Carbon steel version: Cost-effective for conventional shallow oil and gas wells with mild working conditions.
- Easy On-site Installation Lightweight split structure, convenient to assemble without complex special tools. Fast locking design shortens operation time on site, improves tubing running efficiency and reduces construction cost.
- Wide Size Compatibility Customizable inner diameter to fit all common API tubing couplings, covering multiple tubing specifications used in oil production, water injection and gas recovery wells.
