In view of the special performance requirements of pipelines for natural gas transportation in sour oil and gas fields such as corrosion resistance (including CO2, H2S and other acid medium corrosion), high pressure resistance and other special performance requirements, a special flexible composite pipe with resistance to gas penetration and high barrier is designed. According to different processing techniques, it is divided into non-bonded flexible composite pipes and bonded solid-wall continuous composite pipes. According to the different media used, it is divided into high-barrier flexible composite pipes (suitable for sulfur-containing natural gas) and ordinary gas transmission flexible composite pipes.
