Product introduction
RTP Pipe Application
Reinforced thermalplastic pipe have been developed for a spoolable high pressure pipeline, it is used in some applications to instead of the steel pipe because of its advantage of:
Anti-corrosive
Flexible and Spoolable
High pressure up to 15 MPa
Easy installation with a 300-400 meters length in reel
Structure of the RTP pipe
The basic sandwish structure of the RTP pipe is shown as the following figue which include the Liner tube, Reinforcement layer and Cover layer.
Liner tube can be selected for different applications like chemical corrosive, abrasion resistance, temperature resistance, etc. So you can use HDPE, PERT, PEX, PA, UHMWPE, such kind of materials to be the material of the functional tube.
The reinforced layer provide the main pressure against for the RTP pipe. There are some kinds of reinforcement could be selected, like aramid fiber, fiberglass roving, polyester fiber, steel cord...
The outer cover layer gives the protection of the pipe.
Reinforcement Material
The impregnated treatment fiberglass roving is used as the reinforcement, and it is packed in a standard bobbin with bigger diameter about DN300. The glass should select S-glass or E-glass grade. Weight of each bobbin is about 10-12kg, and length is about 2500-3000 meters, tensile of dry fiber is about 0.50N/tex, and after impregnated treatment the single filament tensile is average 2200-2300N. The impregnation material is a kind of polyethylene friend material which has good bonding surface between PE and fiber. One bobbin can produce 1400-1700 meters pipe, working for about 10 hours.
