AFP concept

Your location is:Nachuan Fittings  > AFP concept

AFP abbreviated for “All-Purpose Flexible Pipe”, can be applied in the extremely harsh environment such as ultra-deepwater or heavy oil exploitation.AFP shows unexceptional performance functioning as submarine risers, jumpers, downhole tubing and long-distance flowline, etc. The pipe system constructed from reinforced fibers and thermoplastic polymer is fully bonded with solid wall. With fibers embedded in the polymer matrix, this composite pipe can acquire strong interface adhesion between different layers. The pipe consists of an inner liner, thermoplastic composite reinforcement layers, a functional layer and an outer coating. All layers are of the same thermoplastic polymer and are welded together during the production process.

                              

      Inner liner: Single layer or three-layer co-extrusion solid wall; the selected materials for liner could be PP, PE, PA, PVDF, PPS, PEEK, etc.

Reinforcement layer: Thermoplastic polymer reinforced with fully-bonded fibers processed by continuous winding; the polymer raw materials include PP, PE, PA, PVDF, PPS, PEEK, etc, and the fibers are classified as glass fiber, carbon fiber or aramid fiber, etc.

Functional layer: Contained with electrical cable, optical fiber, various sensors or other function units, this layer plays an excellent role of data transmission, real-state monitoring and integrity control.

Outer coating: Polymer extrusion; the suitable polymer materials such as PP, PE, PA, PVDF, PPS and PEEK are adopted to produce outer coating.

 

       Through variations of materials selection and sectional structures design, AFP products are capable to cope with specific application under different circumstances.
