Description
Technical field
The invention belongs to pipe rehabilitation technology field, in particular to a kind of GRP pipe field repair component and reparation side
Method.
Background technique
In order to alleviate oil field etching problem, glass reinforced plastic road is as an effective way for solving ground transportation network etching problem
Diameter has had been more and more widely used in some new constructions and reconstruction and extension project.Glass reinforced plastic pipe have material specific gravity it is small,
The advantages that corrosion resistance is strong, inner surface is smooth, the coefficient of friction resistance is low, heat transfer coefficient is small, when so that glass reinforced plastic pipe becoming application at present
Between longest, the maximum non-metal pipe of dosage.According to the difference of epoxy curing agent, anhydride-cured glass reinforced plastic pipe can be divided into
With two kinds of arylamine curing glass steel pipe.The type of attachment of glass reinforced plastic pipe mainly include threaded connection, socket joint bonding, locking key connection and
The forms such as flanged joint, wherein being threadedly coupled more commonly used with socket joint bonding.Compared with other non-metallic pipes, major defect is to connect
Head performance and shock resistance are poor, so that glass reinforced plastic pipe failure event happens occasionally, this becomes the bottle for restricting its extension application
Neck.
And at present usually reply glass reinforced plastic pipe leakage, the failure modes such as booster maintenance it is basic there are two types of, one is ways
It is that the needled mat being wound after infiltrating resin using hand paste process to invalid position is repaired.Since glass reinforced plastic pipe failed
Along with the removing of fiber and resin matrix in journey, so that leakage path is one incessantly, the full wafer sweat formula infiltration that sets out often is presented
Leakage.All leakage paths thus cannot be blocked using needled mat canoe, in pipeline later period operational process, pressure-bearing function
Take on mainly by the needled mat of outer layer winding.In addition all scenes of the winding of needled mat have been manually done, former field working conditions
The conditions such as environment (low temperature) limit, and quality is difficult to ensure, the secondary generation leakage situation of pipeline after repairing frequent occurrence.
