Product Description

Seamless capillary coiled tubing for oil and gas industry

 

Meilong is a supplier of welded and redrawn, seamless and redrawn coiled tubing which are made from corrosion-resistant austenitic, duplex, super duplex stainless steels and nickel alloy grades. We have been specializing in manufacturing coiled tubing used in the oil and gas industry.
 

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.
