CNMAX Stainless steel tubing 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.

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 tubing 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 operatin

Manufacturing Range

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.

• Diameter from 3mm (0.118“) to 25.4mm (1.00“) OD.
• Wall thickness from 0.5mm (0.020“) to 3mm (0.118“).
• Typical sizes: 1/4“ x 0.035“, 1/4“ x 0.049“, 1/4“ x 0.065“, 3/8“ x 0.035“, 3/8“ x 0.049“, 3/8“ x 0.065“.
• OD tolerance +/- 0.005“ (0.13mm) and +/- 10% wall thickness. Other tolerances are available on request.
• Coil lengths up to 13,500m (45,000ft) without orbital joints depending on product dimensions.
• Encapsulated, PVC coated or bare line tubing.
• Availableon wooden or steel spools.
