We are a professional and experienced manufacturer in the encapsulated tubings and cables field. We specialize in producing 316L, 316, 304, Incoloy 825, Incoloy 625, 2205, and 2507 Encapsulated Tubings and Tubing Encapsulated Conductors (TEC).
Tubing Encapsulated Conductor (TEC) is designed to supply downhole power directly to gauges and efficiently transfer digital data uphole. The core copper conductor features double insulation, protected securely by a premium stainless steel tube. A specialized Polypropylene coating is applied to provide additional layer protection to the tube wire. Multi-core tubing, TEC, and Encapsulated tubing represent our primary hot-sale product lines. We accept all types of professional third-party testing.
Encapsulation Materials: PVC, F40, F46 Nylon, etc.
Encapsulated Control Line for Downhole Chemical Injection
Our products undergo rigorous evaluation by professional inspection entities including SGS, BV, APPLUS+, and the Center of China National Petroleum Corporation. Every key performance index strictly aligns with American ASTM A269 standards and relative industry guidelines, with specific quality parameters surpassing standard international requirements. Our products are widely utilized and trusted by major operators like CNPC, KOC, KNPC, Halliburton, Baker Hughes, Schlumberger, Weatherford, OXY, and more.
Our standard design includes two joints of 3/8″ x 0.035″ inch sized Encapsulated Control Line flatpacked within a 24mm x 13mm jacket. Custom encapsulation options are available in Santoprene, PVC, F40, F46 Nylon, or other specified materials. The two lines can be color-coded for identification. Tube selections range from weather-resistant stainless steel to advanced alloys like Incoloy 825 or Incoloy 625. Tubing interiors can be pre-flushed, tested, and pre-filled with specified fluids. The flatpack is level-wound onto a heavy-duty wooden drum with protective guards installed to prevent physical damage during shipment and deployment.

Frequently Asked Questions (FAQ)
What are the main applications of Tubing Encapsulated Conductors (TEC)?
TEC is predominantly used to supply downhole electrical power to subsea and deep-well gauges while enabling reliable transmission of digital data back to the surface monitoring equipment.
Which steel grades and materials are available for your control lines?
We offer encapsulation over a wide range of corrosion-resistant alloys and steel tube materials including 316L, 316, 304, Incoloy 825, Incoloy 625, 2205, and 2507 depending on project pressure and environmental requirements.
What encapsulation materials do you support for physical protection?
We support a variety of external jackets, including PVC, F40, F46 Nylon, Santoprene, and other specialized engineering polymers nominated by the customer.
What quality standards do these encapsulated tubes comply with?
Our products are verified by third-party inspection authorities like SGS, BV, and APPLUS+. Every run is manufactured to meet or exceed American ASTM A269 standards along with related oil and gas industry requirements.
How are control lines packaged for shipment to prevent mechanical damage?
The control lines are precision level-wound onto sturdy wooden drums. They are fitted with custom protectors to prevent physical, mechanical, or environmental damage during handling and transportation.
