OEM Supply Alloy 625 Capillary String Control Line - PVDF Encapsulated SAF 2507 Hydraulic Control Line Flatpack – MEILONG

Product Introduction

Meilong Tube specially manufactures seamless and redrawn, welded and redrawn coiled tubing which are made from corrosion-resistant austenitic, duplex, super duplex stainless steels and nickel alloy grades. The tubing is used as hydraulic control lines and chemical injection lines specially serving oil and gas, geothermal industry.

Important

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.

Application

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.

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.
