Stainless Steel /Nickel Alloy 6.35mm Sheath Encapsulation Optical Cable


Stainless Steel /Nickel Alloy 6.35mm Sheath Encapsulation Optical Cable

Fiber optic cables for oil wells offer numerous advantages over traditional copper cables. These cables have higher bandwidth and are less susceptible to interference, allowing for faster and more reliable data transmission. They are also more durable and can withstand harsh environments and extreme temperatures. Additionally, fiber optic cables are immune to lightning strikes and can transmit data over longer distances without the need for signal boosters. These advantages make fiber optic cables an ideal choice for oil well operations that require high-speed, reliable communication over long distances in challenging environments.

MTSCO has been supplying control line for the international geothermal, heat exchanger, shipbuilding, oil and gas industries for more than 10 years. In recent years, we have made breakthroughs in the fields of control line, downhole control lines and chemical injection control lines. We mainly produces welded/seamless control line, single/multi-core control line, capillary tube and other coiled tubing. The main materials are stainless steel, duplex steel and nickel alloy. The length can be more than 33000 fts/coil. The size, length, pressure and packaging method can be customized to ensure equipment quality and reduce maintenance costs.

MTSCO control line has been successfully applied to some harsh seabed and downhole conditions. Through continuous research and development, it can meet the strict quality requirements of the oil and gas industry and other industries.
