控制线广泛用于井下和海底领域的许多应用. Younglee manufactures high quality control lines / 不锈钢和镍合金控制管路.

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:

• 井下液压控制管路
• 井下化学控制管线
• 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
• 别人

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, 聚氯乙烯涂层或裸线管
• Control line tubes are supplied in Coil wound on wooden drum or spool.
• 卷材缠绕在客户特定的金属卷轴上

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, 哥伦比亚, 等.
