Product Description

1/4'' OD X 0.035'' WT

CNMAX Stainless Steel provides a wide range of tubular product forms and materials mainly for the oil & gas sector. 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.

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.

• Duplex 2205

• Super Duplex 2507

• Incoloy 825

• Inconel 625



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.


Production process

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.

Seam-welded and redrawn tubing.

Seamless and redrawn tubing.


Dimensional range

Diameter from 3.18mm (0.125``) to 25.4mm (1.00``) OD.

Wall thickness from 0.51mm (0.020``) to 3mm (0.118").

OD tolerance +/- 0.005`` (0.13mm) and +/- 10% wall thickness. Other tolerances are available on request.

Coil lengths up to 1500m (5,000ft) without orbital joints depending on product dimensions.

Coil lengths up to 13,500m (45,000ft) with orbital joints.

Encapsulated, PVC coated or bare line tubing.

Available on wooden or steel drums.


The above are tested in the condition of coiled tubing with orbital joints

All joints are X-ray tested

Control line may also be supplied without orbital joints

Certification to EN10204, 3.1



Redrawing process of welded tubes

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.


Seamless tubing has cross sectional uniformity however, it is the most expensive method of manufacture and has a limitation in the continuous length that can be produced between joints. For a slight premium over the welded & sunk price, tubing can be produced by the welded & floating plug drawn process which results in a product of similar appearance to seamless but with the significant advantage of much longer continuous lengths and greatly reduced costs.


Quality assurance
