High Tensile Stainless Steel Coiled Tubing

Super Duplex 2507 UNS S32750 High Tensile Chemical Injection Line Capillary Tubing

 

One of the main challenges in the upstream processes of the oil and gas industry is to protect pipeline and process equipment against waxes, scaling and asphalthane deposits. The engineering disciplines involved in flow assurance play an essential part in mapping the requirements that reduce or prevent loss of production due to pipeline or process equipment blockage. Coiled tubing from Meilong Tube is applied to umbilicals and chemical injection systems play an effective role in chemical storage and delivery at an optimizing flow assurance.

 

Our tubing is characterized with integrity and quality to be specially used in subsea conditions in the industries of oil and gas extraction.

 

Meilong Tube manufactures corrosion resistant alloy hydraulic control line tubing products for a variety of upstream oil and gas and geothermal applications. Meilong Tube has extensive experience in producing coiled tubing from duplex, nickel alloy and stainless steel grades to industry and customer-specific requirements.

 

Application

 

To assure produced fluid flow and protect your production infrastructure from plugging and corrosion, you need reliable injection lines for your production chemical treatments. Chemical injection lines from Meilong Tube help enhance the efficiency of your production equipment and lines, both downhole and at surface.

 

Importance of Capillary Tubing

 

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

Each one tubing coil is hydrostatic tested at minimum 11,600 psi.

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.

 

Vacuum Annealing for Injection Lines

 

Meilong Tube takes special care during manufacturing to assure cleanliness of inside surface and outside surface of control lines & chemical injection lines. Vacuum annealing insures volatility of metallic oxides and removal of any residual degreasing solvents or drawing lubricants. Vacuum annealing our alloy tubing insures a bright, cosmetically appealing surface as well as excellent mechanical properties.

Duplex 2507 is a super duplex stainless steel designed for applications which demand exceptional strength and corrosion resistance. Alloy 2507 has 25% chromium, 4% molybdenum, and 7% nickel. This high molybdenum, chromium and nitrogen content results in excellent resistance to chloride pitting and crevice corrosion attack and the duplex structure provides 2507 with exceptional resistance to chloride stress corrosion cracking.

 

Usage of Duplex 2507 should be limited to applications below 600° F (316° C). Extended elevated temperature exposure can reduce both the toughness and corrosion resistance of alloy 2507.

 

Duplex 2507 possesses excellent mechanical properties. Often a light gauge of 2507 material can be used to achieve the same design strength of a thicker nickel alloy. The resulting savings in weight can dramatically reduce the overall cost of fabrication.

 

Corrosion Resistance Suitable for Down Hole Applications

 

2507 Duplex is highly resistant to uniform corrosion by organic acids such as formic and acetic acid. It is also highly resistant to inorganic acids, especially if they contain chlorides. Alloy 2507 is highly resistant to carbide-related intergranular corrosion. Due to the ferritic portion of the duplex structure of the alloy it is very resistant to stress corrosion cracking in warm chloride containing environments. Through additions of chromium, molybdenum and nitrogen localized corrosion such as pitting and crevice attack are improved. Alloy 2507 has excellent localized pitting resistance.
