Duplex 2507 Capillary Coiled Tubing with Ferrule Fittings Working Pressure Above 10000 Psi
Product Description:
Meilong Tube specialises in the production of seamless and redrawn, welded and redrawn coiled tubing. Made from austenitic stainless steels, duplex stainless steels and nickel alloy grades, this type of tubing is primarily used for the purpose of hydraulic control lines and chemical injection lines for oil and gas, and geothermal industry.
Unique capabilities enabled by Meilong Tube make our coils the longest continuous chemical injection line available in stainless steels and high nickel alloys. Furthermore, with an exceptionally clean and smooth inside surface, they are great for chemical injection systems due to the shorter hydraulic response time and increased collapse strength. In addition, there are lesser incidences of methanol permeation.
Duplex 2205 is a nitrogen-enhanced duplex stainless steel, designed to combat common corrosion problems encountered when using 300 series stainless steels. It is composed of a ferrite-austenite structure, with approximately 40-50% ferrite in the annealed condition. This grade is the most commonly used duplex alloy and displays excellent resistance to various forms of corrosion. It combines the favorable qualities of both a ferritic alloy (such as stress corrosion cracking resistance and higher strength) with those of an austenitic alloy (facility of fabrication and corrosion resistance). However, it should only be used in temperatures below 600 °F, as higher temperature exposure may cause embrittlement. The combination of chromium, molybdenum and nitrogen found in Duplex 2205 give it excellent resistance to chloride pitting and crevice corrosion. This is particularly useful in marine environments, brackish water, bleaching operations, closed loop water systems and food processing applications,
rendering it superior to other stainless steel grades like SS316L and SS317L in many environments.
Features:
Each one tubing coil crafted by Meilong Tube is a completely continuous length, free of any orbital welds. Every coil is hydrostatically tested at a minimum of 10,000 psi, and can be witnessed on site by third party inspectors such as SGS, BV, and DNV. Additionally, board tests such as eddy current testing, chemicals, flattening, flaring, tensile and yield, elongation, and hardness are done to ensure material quality.
Furthermore, Vacuum annealing is done during manufacturing in order to guarantee cleanliness for both inside and outside surfaces of control lines and chemical injection lines. The vacuum annealing removes any degreasing solvents or drawing lubricants, as well as granting a bright exterior to the tubes and improving its mechanical properties.
