Flexible composite high-pressure transport pipe (referred to as flexible composite pipe) is a non-metallic pipe with a multi-layer structure, generally consisting of The inner lining layer, the reinforcement layer and the outer protection layer are wrapped layer by layer. The flexible composite pipe has certain flexibility and can be coiled into several Hundreds of meters to several kilometers long, to achieve continuous laying, also known abroad as flexible composite pipe can be coiled enhanced plastic pipeline, enhanced Composite plastic pipe (RTP).Flexible composite pipe can be divided into flexible composite pipe for land and flexible composite pipe for downhole according to laying method; flexible composite pipe for oil and gas field can be divided according to usage. Flexible composite pipe for oil and gas fields and coal mines. According to the structure, it can be divided into bonded flexible composite pipe and non-bonded type flexible composite pipe.Translated with DeepL
