Control Lines Brief Introduction
Control lines usually are coiled tubes made of stainless steel, duplex stainless steel or nickle alloys. The coiled tubes mostly are welded & redrawn tubes or seamless cold drawn tubes. Control lines are usually supplied with very long continuous lengths coiled on the drums.
Control lines are broadly applied in many applications, such as below:
- Downhole hydraulic control lines
- Downhole chemical control lines
- Subsea control lines for hydraulic power and chemical injection line
- Flowline control
- Instrumentation tubing
- Smooth inner surface control line tubing used in fibre optic applications
- Autrui
Control Line Tube Manufacturing Forms
As the professional manufacturer of control lines, Younglee makes long coils of control line tubing in three main forms as below:
- Seamless Tube – a billet of round bar is extruded or hot piercing into a tube and then cold rolled and drawn to final size.
- Welded and re-drawn Tube – a strip of metal is formed and being welded to a tube, then the tube is drawn through a mold to remove (homogenize) the weld seam. Some customers also call this type “seamless”.
- Welded and floating plug drawn – the weld tube is drawn through a mold with a floating plug in the bore to rework the weld seam internally and externally.
For more details on quality considerations, the advantages of redrawing welded tubes, and pressure calculations, please contact us for the control line datasheet.
Control Line Packing standards
- Control line tubes can be supplied as encapsulated, PVC coated or bare line tubing
- Control line tubes are supplied in Coil wound on wooden drum or spool.
- Bobines enroulées sur des bobines métalliques spécifiques au client
As one of the leading China control line tube factory, Baosheng control line is widely supplied to customer domestic and abroad. Our control line tubes are exported to many customers in the oil and gas field in many countries, such as Russia, Saudi Arabia, Colombia, etc.
