From Raw Tube to Encapsulated Control Line: See How It's Made

Multi-core control line manufacturing begins with premium 316L stainless steel capillary tubing. After precision automatic welding forms continuous coiled tubing, the tubing undergoes critical cold drawing and bright annealing processes to achieve uniform grain structure and superior mechanical properties. Multiple single tubes are then bundled into control lines via precision stranding technology. Finally, under strictly controlled temperature and speed conditions, the tube undergoes co-extrusion encapsulation with PVDF or FEP to form a complete, sealed protective layer.

Encapsulation Material Properties (PVDF and FEP)

The PVDF and FEP encapsulation layers used in this product are specifically designed for demanding conditions. PVDF offers outstanding mechanical strength, wear resistance, and UV aging resistance. It is suitable for outdoor environments and applications with moderate mechanical impact. FEP is renowned for its exceptional chemical inertness, superior electrical insulation, and broader operating temperature range (-200°C to +200°C), making it particularly suitable for highly corrosive media. MTSCO can recommend and provide the most suitable encapsulation material solution based on your specific application environment, ensuring long-term stable pipeline operation.

 Multi-Core Control Line FAQ

Q1: What packaging options are available for coiled cables? How is shipping damage prevented?

A1: We offer multiple packaging solutions including plastic reels, wooden reels, solid wooden reels, iron reels, iron-wood hybrid reels, and wooden boxes. During loading into shipping containers, we reinforce packages with wooden strips and ropes to prevent transit impacts and ensure safe delivery.

Q2: What is the maximum length per coil for this multi-core control line?

A2: Our welded coiled tubing can reach up to 50,000 feet (approximately 15 kilometers) per coil, meeting long-distance underground cabling requirements. This reduces field splicing and enhances system reliability. MTSCO's factory possesses ultra-long continuous production capabilities.

Q3: What is the maximum working pressure for the coils?

A3: Our welded coils undergo standard hydraulic testing at 5000 PSI and can withstand up to 15000 PSI testing pressure, meeting the requirements of most high-pressure applications. Actual working pressure must be calculated based on specific material, wall thickness, and operating temperature. MTSCO provides professional technical parameter selection support.
