SS316L High Burst Pressure Coiled Tubing Capillary Line Inconel 625

High burst pressure coiled tubing capillary line made from Inconel 625


Meilong Tube specially manufactures seamless and redrawn, welded and redrawn coiled tubing capillary line 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 Capillary Line


Outside diameter of capillary lines is mainly 1/4’’ (6.35mm).

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

Capillary 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 Capillary Line


Each one capillary line in form of tubing coil is a completely continuous length without orbital welds.

Each one hydraulic line in form of tubing coil is hydrostatic tested at minimum 15,000 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 Description for Capillary Line


In all fields of the oil and gas industry, chemicals are injected into process lines and fluids. Take oilfield services, chemicals are used to film the side of the wellbore for improved stability. In pipelines they avoid build-up and keep the infrastructure healthy.


The Role of Capillary Line


In the oil and gas industry we inject chemicals in order

to protect the infrastructure

to optimize processes

to assure flow

and to improve productivity

Inconel 625 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


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.
