Coiled tubing is available in a range of different product forms depending on the customer requirements. We manufacture seam welded and redrawn, 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.
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.
Applications
• Downhole hydraulic control lines.
• Downhole chemical control lines.
• Subsea control lines for hydraulic power and chemical injection.
• Smoothbore control lines used in fibre optic applications.
