Product material
The 1/4" O.D. x 0.049" W.T. 316L super coiled tubing welded control line is made from 316L austenitic stainless steel, which is highly valued for its excellent corrosion resistance and mechanical properties. Known for its low carbon content, 316L stainless steel minimizes carbide precipitation, which prevents intergranular corrosion and enhances its durability in marine and chloride-rich environments.

Applications
Hydraulic Control Lines for Subsea Applications: Due to its excellent corrosion resistance, 316L stainless steel is ideal for subsea hydraulic systems, where it is used to operate valves, actuators, and other equipment on the seabed. The tubing’s coiled design enables it to be installed in long continuous lengths, reducing potential leak points.
Downhole Chemical Injection: The tubing is used to transport chemicals like corrosion inhibitors and scale inhibitors directly to downhole reservoirs. 316L stainless steel’s high corrosion resistance is crucial for maintaining performance under extreme downhole conditions.
Control Lines for Safety Valves: In oil and gas wells, these control lines are connected to surface-controlled subsurface safety valves (SCSSVs) and allow operators to remotely open or close the valves. This ensures well integrity and safety, even under high pressure and corrosive conditions.
Umbilical Systems in Offshore Operations: In offshore applications, super coiled 316L control lines are integrated into umbilical systems, which combine power, control, and communication lines. They are used for remote monitoring and operation of subsea equipment, enhancing efficiency and safety.
Instrumentation and Monitoring Lines: 316L control lines are used for transmitting pressure or temperature data from sensors to monitoring systems. Its durability in corrosive environments makes it an ideal choice for continuous and reliable instrumentation.
