Description
Technical field
Pipeline field is the utility model is related to, especially a kind of RTP tube road.
Background technology
RTP tube road is the abbreviation of fiber reinforced thermolplastic multiple tube, is made of inner tube, fiber-reinforced layer, outer tube.Because of its tool
Have corrosion-resistant, high pressure resistant, light-weight, flexible high, the features such as can coiling, be widely used in land, oil, sewage, chemicals,
The fields such as fuel gas transmission, are even more to be applied to submarine oil feed-line in recent years.
Traditional two kinds of manufacture methods of RTP tube：
The first winds dry fibers yarn not gluing on HDPE resin outer wall of inner tube, and then pipeline outermost layer coats one layer again
PE resin outer tubes.Although internal pressure can be born by the RTP tube road of this kind of technique productions, because its structure sheaf does not have for two layers with inside and outside
Adhesive strength, so pipe ring ratio of rigidity is relatively low, under axial tension, ectonexine is easily separated from or shifts, which greatly limits
The connection mode of pipe joint, therefore can only use and be inserted into metal joint in HDPE internal diameter of the pipeline, to solve connectivity problem.
Second is that inner tube uses HDPE resin inner tube, and structure sheaf is wound using pre-soaking fiber band, Fiber Winding process
In, heated using hot wind, melt pre-soaking fiber belt surface, be bonded layer by layer, finally coat PE resin outer tubes, this kind of manufacturer again
Method shortcoming is：1 fiber with hot wind heating and fiber band is wound under motion state in fusion process is wound, institute
Incomplete to easily cause the fusing of pre-soaking fiber belt surface, the fiber band after winding can not bond completely with tube wall, in addition
When hot wind melts, hot wind, which can also slip into, forms bubble in colloid, this will cause pipe layers shear strength unstable.2 this kinds are made
Method is made because in process of production, production pre-soaking fiber band cost is higher, is the 3 of homo-fibers yarn using pre-soaking fiber band
Times.
The anti-shear ability deficiency in the RTP tube road of both the above structure, when connection, can only be connected by HDPE resin inner tube
