Coil Formed Tubes
Specialized tubing known as control line tubing is utilized for transmitting hydraulic fluids and control signals across various industries. This precisely constructed tubing guarantees precise communication and control among different system components, particularly in challenging or remote environments.
Control line tubing is often found in applications such as oil and gas wells, where it helps regulate wellbore pressure, monitor temperature, and manage fluid injection. It’s also crucial in aerospace and automotive sectors for hydraulic and pneumatic systems.

KRYSTAL has been providing coiled tubing for the international geothermal, heat exchanger, shipbuilding, oil and gas industries for over a decade. We can produce according to various international standards, with main materials including 304/316/2205/2507/alloy 625/825, etc.
In recent years, we have continuously made breakthroughs in the fields of coiled tubing, downhole control line, and chemical injection line. We mainly produce welded/seamless coiled tubing, capillary tubes, control line tubing, multi core tubing and cables.
KRYSTAL seamless coiled tubing can be up to 33,000fts/coil. And it can pass the max hydraulic pressure of 100MPA. Our seamless coiled tubing can be up to 120kgs/ coil. We can provide various encapsulated plastic material, such as PP,TPV,TPU,PVC,PVDF…
