Description
Technical field
The utility model is related to non-metal composite pipe product manufacturing technical fields, are specially a kind of company with leakproofness connector
Continuous fibre-reinforced thermoplastic's multiple tube.
Background technology
With progressively going deep into for oilfield development process, surface gathering and transferring pipeline performance work condition environment is increasingly harsh, tradition
Carbon steel pipe faces severe etching problem.There is corrosion-resistant, long lifespan, nonmetallic and composite material tube easy for construction
Material (referred to as non-metallic pipe) is increasingly becoming the important aspect for solving oil gathering and transportation pipelines etching problem.Reinforced thermoplastics is answered
Pipe is closed because its is continuously shaped, it is single up to hundreds of meters, connector it is few, it is flexible, shock resistance is excellent, light-weight, transportation cost
Low, the series of advantages such as installation is quick and easy are used widely in oil gas field, become the nonmetallic of most development potentiality
Pipe.
The non-adherent that current China reinforced thermoplastics composite pipe body product enhances for steel wire/steel band or polyester fiber
Type structural tube, connector makes withholds mode using metal:Metal core pipe is inserted into compound inside pipe wall, is then filled using hydraulic pressure
The metal sleeve that compound pipe outer wall is sleeved on along multiple tube radial compression is put, by means of enough radial compression stress, realizes metal
The mechanical bond of connector and multiple tube.Although metal core pipe and metal sleeve have carried out special tooth Shape Design, while also apply
Enough radial pressures are added, but a large amount of laboratory tests and the field application for non-adherent infrastructure product are the results show that conveying
Medium can penetrate into metal sleeve along the interface of withholding of compound inside pipe wall and metal core pipe, and then penetrate into compound end surfaces, and along
Interface continues to circulate between composite pipe lining layer, structure sheaf and external protection.Accumulate in the pumped (conveying) medium meeting between each structure sheaf
Cause composite pipe structure unstability, the external protection bulge and then possibility to burst greatly increases.
It is the binding type reinforced thermoplastics multiple tube represented as solution using continuous fiber reinforced thermoplastic plastic multiple tube
Fabulous selection is certainly provided with top connection gate oxide integrity problem.Continuous fiber reinforced thermoplastic plastic multiple tube is by thermoplastic
Property polymer extruding pipe and continuous fiber reinforced thermoplastic plastic band winding bonding solid wall pipe is made, be bonded as between each structure sheaf
It can effectively avoid pumped (conveying) medium after one to circulate along the infiltration at interface, the sealing for improving multiple tube to a certain extent is complete
Property.But the connector production method and non-adherent infrastructure product of current the type multiple tube are substantially similar, can not fundamentally prevent
The infiltration of pumped (conveying) medium.It must take into consideration further optimization continuous fiber reinforced thermoplastic plastic composite pipe structure as a result, promoted multiple
The leakproofness at pipe fitting position is closed, could be to ensure multiple tube gate oxide integrity, product failure risk is reduced and important leverage is provided.
