Control line Manufacturing Range The Oil & Gas sector represents one of Fine Tubes principal markets for supply of a wide range of tubular product forms and materials. Our products have been successfully used in some of the most aggressive subsea and downhole conditions and we have a long proven track record of supplying products that meet the strict quality requirements of the Oil & Gas and geothermal energy sectors. Coiled tubing is available in a range of different product forms depending on the customer requirements. We manufacture seam welded and redrawn, seam welded and floating plug redrawn and seamless tube products. The standard grades are 316L, alloy 825 and alloy 625. Other grades of stainless steel in duplex and superduplex and nickel alloy are available on request. Tubing can be supplied in the annealed or cold worked condition. Improvements in the technology for the enhanced exploitation of oil and gas fields has increasingly required the use of long continuous lengths of stainless steel and nickel alloy tubulars for hydraulic control, instrumentation, chemical injection, umbilical and flowline control applications. The benefits of this tubular technology have resulted in reduced operating costs, improved recovery methods and reduced capital expenditure by connecting downhole valves and chemical injection with remote and satellite wells to a fixed or floating central operating platform. Applications Fine Tubes offers coiled control line in stainless steel and nickel alloys. Our products are used in the following applications: • • • • Downhole hydraulic control lines.

Control line Control Line Product Forms Types of tubing Long coils of tubing can be manufactured in four main forms: • Seamless – in which a billet of metal is extruded into a tube and drawn to final size. • Welded* – made by forming a strip of material into a tube and welding the seam. Some local cold work on the weld may also be applied by calibrating rolls. • Welded & Sunk – after being welded the tube is drawn through a die to homogenise the seam weld. • Welded & Floating Plug Drawn – after being welded the tube is drawn through a die with a floating plug in the bore to rework the weld...

Control line Advantages of Redrawing Welded Tube Control Line Pressure Calculations Long lengths can be made by seam welding formed strip but such tubing has OD & ID discontinuity and may suffer from local problems of mechanical strength or corrosion. A welded & sunk tube improves these aspects and has been proven reliable in service over several decades for offshore applications. Although more expensive than welded only tubing, the welded and redrawn tube is still relatively inexpensive compared to seamless. The working pressure for a tube depends on the operating conditions of each...
