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 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.
The control line is 100% dimensionally inspected and eddy current tested to international ASTM or DIN standards. All lines are 100% hydraulically pressure tested before being released and certified. Any orbital joints are also radiographically tested in a minimum of 3 planes to ensure the quality of the joint.
Coiled tubing is available in a range of different product forms depending on customers' requirements. We specilize in providing 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.
