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:
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.
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.
