Typical Applications
Downhole Control Lines
Hydraulic control lines for sub-surface safety valves, flow control devices, and intelligent well completions. Rated for high-pressure, high-temperature (HPHT) well conditions.
Subsea Umbilicals
Core component of subsea umbilical systems providing hydraulic, chemical injection, and electrical signal pathways between surface facilities and subsea equipment.
Chemical Injection Lines
Precision lines for injecting corrosion inhibitors, scale inhibitors, methanol, and other chemicals directly into wellbores and flowlines to maintain flow assurance.
Instrumentation & Sensing
Small-diameter tubing for pressure gauges, temperature sensors, fiber optic monitoring, and distributed sensing systems in permanent downhole monitoring.
