factory customized Alloy 825 Chemical Injection Line Tube - Super Duplex 2507 Chemical Injection Line Tube – MEILONG

Product introduction

One of the main challenges in the upstream processes of the oil and gas industry is to protect pipeline and process equipment against waxes, scaling and asphalthane deposits. The engineering disciplines involved in flow assurance play an essential part in mapping the requirements that reduce or prevent loss of production due to pipeline or process equipment blockage. Coiled tubing from Meilong Tube is applied to umbilicals and chemical injection systems play an effective role in chemical storage and delivery at an optimizing flow assurance.

Our tubing is characterized with integrity and quality to be specially used in subsea conditions in the industries of oil and gas extraction.

Alloy Feature

Corrosion Resistance

2507 Duplex is highly resistant to uniform corrosion by organic ac Super Duplex 2507 Plateids such as formic and acetic acid. It is also highly resistant to inorganic acids, especially if they contain chlorides. Alloy 2507 is highly resistant to carbide-related intergranular corrosion. Due to the ferritic portion of the duplex structure of the alloy it is very resistant to stress corrosion cracking in warm chloride containing environments. Through additions of chromium, molybdenum and nitrogen localized corrosion such as pitting and crevice attack are improved. Alloy 2507 has excellent localized pitting resistance.
