Flexible Composite Pipe For Conveying Gas

Special flexible composite pipe for Shale gas/natural gas transmission

In response to the special performance requirements of pipeline corrosion resistance (including CO2, H2S and other acidic media corrosion) and high pressure resistance for natural gas transmission in acidic oil and gas fields, a special flexible composite pipe with high gas permeability resistance and 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.

Flexible composite pipe (suitable for sulfur-containing natural gas) with high barrier
Mainly designed for the corrosion of acidic media such as CO2 and H2S in the gas transported by oil and gas fields, high gas pressure, and complex transportation environment. High barrier non-metallic flexible continuous composite pipe is an upgraded product of traditional flexible composite pipe. The pipe is composed of five layers of co extruded inner liner transmission layer, reinforcement layer, and outer protective layer. The inner lining of the full diameter high barrier non-metallic flexible continuous composite pipe is formed by co extrusion of heat-resistant polyethylene (PE-RT), adhesive, and high barrier polyethylene (EVOH) in five layers; The reinforcement layer is formed by winding polyester fibers; The outer covering layer is made of high-density polyethylene (HDPE).
