Application

Duplex Stainless 2205 seam welded pressure tubing in the heat treated condition is typically used in oil and natural gas wells for chemical injection applications. In such applications, it is commonly referred to as capillary tubing and is free-hanging (self-supporting) inside the production casing. The chemicals being injected are often used to enhance production flow rates, inhibit corrosion or scaling and/or de-water. However, the tubing can also be used for control line tubing applications including hydraulically actuated surface-controlled subsurface safety valves. For control line applications, the tubing is generally deployed by strapping it to the outside of the production casing. The tubing is frequently supplied as 5,000 to 35,000 ft. coils on a wooden or steel reel, depending on size.

 

Description

Duplex Stainless 2205 is a duplex stainless steel. When properly heat treated, the microstructure consists of a nearly equal mixture of the austenitic and ferrite phases. This two-phase microstructure produces a fine grain size which increases the yield strength. In the final heat treated condition, Duplex Stainless 2205 can achieve a yield strength approximately twice that of austenitic alloys such as 316L, 825 and 625 which must be cold worked to achieve comparable yield strengths. Duplex stainless steels are often classified as lean, conventional, super or hyper based upon their pitting resistance equivalent (PRE or PREN). Various PRE formulas are used to rank an alloy’s resistance to chloride pitting corrosion based upon its composition. Duplex Stainless 2205 typically has a PRE of 36 and is considered a conventional duplex stainless steel. Duplex Stainless 2205 is often selected for use in oil and gas production environments based upon its higher strength and resistance to pitting, crevice and stress corrosion cracking in chloride containing environments. Consult ISO 15156-3, Table A.24 for the limits regarding the use of Duplex Stainless 2205 in hydrogen sulfide containing environments for oil and gas production.

Corrosion Resistance

2205 duplex stainless steel is a cost effective solution for many applications where the 300 series stainless steels are susceptible to chloride stress corrosion cracking. Stress corrosion cracking occurs when stainless steels are subjected to tensile stress, while in contact with solutions containing chlorides. Increasing temperatures also increase the susceptibility of stainless steels to stress corrosion cracking.

 

The combination of chromium, molybdenum and nitrogen convey the good resistance of 2205 to chloride pitting and crevice corrosion. This resistance is extremely important for services such as marine environments, brackish water, bleaching operations, closed loop water systems and some food processing applications. The high chromium, molybdenum and nitrogen contents of 2205 provide corrosion resistance superior to common stainless steels, such as, 316L and 317L in most environments.

Since 1999, Meilong Tube Co., Ltd. has produced both long coils and straight length of stainless steel and high nickel alloy tubing for numerous oil and gas applications, including hydraulic power, monitoring and control equipment, instrumentation, injection lines, down-hole safety valve control, subsea umbilical applications. Unique manufacturing capabilities and processes allow Meilong to produce the longest continuous length control line tubing available in stainless steels and high nickel alloys.

 

Our coiled tubing is available in a number of high performance corrosion resistant stainless steels and high nickel alloys, including 300 series, Incoloy, Inconel, capable of withstanding a variety of severe environmental conditions.

 

We specialize in manufacturing small diameter tubing ranging from 0.125 inch to 1 inch outside diameter (3.18mm to 25.4 mm) and a variety of wall thickness. Besides straight length instrumentation tubing, tubing is level wound coiled on various size spools, and products are tested and evaluated for specific applications before delivery. Our engineering staff welcome the opportunity to work with customers to solve special problems.

 

Vacuum annealing

Meilong takes special care during manufacturing to assure ID and OD cleanliness of instrumentation tubing. Vacuum annealing insures volatility of metallic oxides and removal of any residual degreasing solvents or drawing lubricants. Vacuum annealing our stainless steel tubing insures a bright, cosmetically appealing surface as well as excellent mechanical properties.

 

Meilong commitment to quality excellence

From the time an order is received, sent through the production process, completed, and finally shipped, many levels of inspection occur to reinforce Meilong’s Quality Policy. The job of ensuring quality products extends as far as our machine operators. Meilong operators take ownership over material processed at their stations by measuring for dimensional accuracy and conducting a visual inspection of every piece.
