1 / 4 '' OD X 0.065 '' Copper Nickel Brake Tubing Hydraulic Control Line Incoloy 825

1 / 4 '' OD x 0.065 '' WT nickel alloy tubing hydraulic control line made from Incoloy 825

The nickel alloy tubing products for the oil & gas sector have been successfully applied 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 and gas sector.

Meilong Tube offers control line tubing in a wide range of corrosion resistant stainless steels, nickel alloys. We have extensive experience in product supply and innovation in this sector, from the technological advances required for subsea developments in the 1999 to the deepwater challenges of today

Typical Size of Nickel Alloy Tubing Control Line

Outside diameter of nickel alloy tubing control lines is mainly 1/4’’ (6.35mm).

Wall thicknesses: 0.035’’ (0.89mm), 0.049’’ (1.24mm), 0.065’’ (1.65mm)

Control line tubing is available in lengths from 400 feet (122 meters) to 32,808 feet (10,000 meters). No orbitally butt welds.

Other specifications (1/8’’ to 3/4’’) are available on request.

Features of Nickel Alloy Tubing Control Line

Each one tubing coil is a completely continuous length without orbital welds.

Each one tubing coil is hydrostatic tested with a targeted pressure.

The test can be witnessed on site by the third party inspectors (SGS, BV, DNV).

Other tests are eddy current test, chemicals, flattening, flaring, tensile, yield, elongation, hardness for the material quality.

Testing Abilities for Nickel Alloy Tubing Control Line

Process and Packing for Nickel Alloy Tubing Control Line

Seamless: pierced, redrawn, annealed (multi-pass circulation process)

Welded: longitudinally welded, redrawn, annealed (multi-pass circulation process)

Packing: Tubing is level wound coiled on the metal / wooden drums or spools.

All drums or spools are packed in wooden crates for easy logistic operation.

Alloy Materials

Alloy Feature

Incoloy alloy 825 is a nickel-iron-chromium alloy with additions of molybdenum and copper. This nickel steel alloy’s chemical composition is designed to provide exceptional resistance to many corrosive environments. It is similar to alloy 800 but has improved resistance to aqueous corrosion. It has excellent resistance to both reducing and oxidizing acids, to stress-corrosion cracking, and to localized attack such as pitting and crevice corrosion. Alloy 825 is especially resistant to sulfuric and phosphoric acids. This nickel steel alloy is used for chemical processing, pollution-control equipment, oil and gas well piping, nuclear fuel reprocessing, acid production, and pickling equipment.

Meilong Tube manufactures high quality seamless and redrawn, seam-welded and redrawn coiled tubing which are made from corrosion-resistant austenitic, duplex, super duplex stainless steel and nickel alloy grades. 100% of products are used as hydraulic power control lines, chemical injection lines, alloy tubing in umbilicals and instrumentation tubing for the exploitation engineering in the upstream oil and gas industry.

Coiled tubing is available in sizes arrange from outer diameter 0.125 inch (3.175 millimeters) to 1 inch (25.4 millimeters). Wall thickness is up to 0.083 inch (2.108 millimeters). Lengths up to 65600 feet (20,000 meters) are available for cost-effective umbilical manufacturing. More sizes within the scope can be customized to be produced and delivered for meeting your special requirements.

As more oil and gas extractions move into deeper and harsher waters where extreme offshore environments demand extreme safety, our work is to help you use the “right” corrosion resistant material for coiled umbilical tubing to improve the safety and reliability of your work. This is the power for driving our innovations and continuous development.

Now Meilong Tube is devoting its capability to bring global customers most cost-effective tubing products through ensuring a comprehensive supply guarantee regarding the complete value-added chain in tubing production and is herewith the basis for the high performance in products and customer satisfaction.
