FEP Encapsulated Control Line Flatpack with Single Tube for Downhole Chemical Injection

 

Meilong Tube offers the encapsulation of control lines to provide increased durability, as well as chemical and corrosion resistance to meet each project’s specialized requirements, we offer different encapsulation types, such as: HDPE (High Density Polyethylene), Santoprene, PVC (Polyvinyl Chloride), Haylar and PVDF (Polyvinylidene Fluoride).

 

Welded hydraulic control line is floating plug drawn to ASTM specifications and is available in any length. Material types for hydraulic control lines include stainless steel TP316L which is suitable for sweet to moderately corrosive environments, Duplex stainless steel 2205, Super Duplex stainless steel 2507, nickel alloy Incoloy 825 and Inconel 625 are suitable for severely corrosive environments and high working pressures and temperatures. Control system fluids must be compatible with the environments and operating temperatures of the control line.

 

Control line encapsulation also is available, where requested, to provide additional crush and abrasion resistance during installation. The encapsulation material should be matched for compatibility with well fluids and temperature requirements.

 

Encapsulated Control Line Flatpack

 

Encapsulation is a plastic that is extruded over metal tube. Encapsulation prevents damage to the metal tubes during the manufacturing process. The encapsulation also provides additional abrasion resistance and is required if cable protectors are installed to enhance the holding force over each production tubing connection.

 

Encapsulations are available in a wide range of configurations with options of single pass encapsulation and dual pass encapsulation for added protection.

 

Application of Flatpack

 

Flatpacks are commonly used when several different lines are terminated at approximately the same depth in the well.

Common applications include intelligent well systems, deep-set chemical injection lines with downhole gauge cable and safety valve lines with shallow set chemical injection lines. For some applications bumper bars are also encapsulated into the flatpack to provide additional crush resistance.

 

Standard & Approvals

 

Control Lines are manufactured according to applicable ASTM standards for each specific material.

Tubes can be supplied flushed, filled, and filtered per client requirements and to the appropriate NAS/SAE standards.

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 of Super Duplex 2507

 

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.
