Hydrostatic Tested Inconel 625 Capillary Tubing Chemical Injection Line for Geothermal Wells

 

  Meilong Tube specially manufactures seamless and redrawn, welded and redrawn hydraulic control line capillary tube 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.

 

Typical Size of Inconel 625 Capillary Tubing

 

Outside diameter of chemical injection lines is mainly 3/8’’ (9.53mm).

Wall thicknesses: 0.035’’ (0.89mm), 0.049’’ (1.24mm), 0.065’’ (1.65mm), 0.083'' (2.11mm)

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.

 

Importance of Inconel 625 Capillary Tubing

 

Each one nickel alloy Incoloy 625 tubing capillary tube is a completely continuous length without orbital welds.

Each one tubing coil is hydrostatic tested at minimum 10,150 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.

 

Application for Inconel 625 Capillary Tubing

 

Chemical Injection Line

 

A small-diameter conduit that is run alongside production tubulars to enable injection of inhibitors or similar treatments during production. Conditions such as high hydrogen sulfide [H2S] concentrations or severe scale deposition can be counteracted by injection of treatment chemicals and inhibitors during production.

 

A general term for injection processes that use special chemical solutions to improve oil recovery, remove formation damage, clean blocked perforations or formation layers, reduce or inhibit corrosion, upgrade crude oil, or address crude oil flow-assurance issues. Injection can be administered continuously, in batches, in injection wells, or at times in production wells.

Material Description

 

Inconel 625 is a material with excellent resistance to pitting, crevice and corrosion cracking. Highly resistant in a wide range of organic and mineral acids. Good high temperature strength.

 

Characteristics of Inconel 625

 

Excellent mechanical properties at both extremely low and extremely high temperatures.

Outstanding resistance to pitting, crevice corrosion and intercrystalline corrosion.

Almost complete freedom from chloride induced stress corrosion cracking.

High resistance to oxidation at elevated temperatures up to 1050C.

Good resistance to acids, such as nitric, phosphoric, sulfuric and hydrochloric, as well as to alkalis makes possible the construction of thin structural parts of high heat transfer.

 

Inconel 625 for Application 

 

Components where exposure to sea water and high mechanical stresses are required.

Oil and gas production where hydrogen sulfide and elementary sulfur exist at temperature in excess of 150C.

Components exposed to flue gas or in flue gas desulfurization plants.

Flare stacks on offshore oil platforms.

Hydrocarbon processing from tar-sand and oil-shale recovery projects.
