Abstract
The utility model belongs to the technical field of conveying pipe and discloses a flexible composite high pressure conveying pipe for petroleum and natural gas industries, which is characterized by comprising a nylon core. The outer wall of the nylon core is wrapped by a steel wire winding reinforcement layer and a protecting layer, an extensible pipe formed by meshing and rolling positive and negative type folding steel plates is arranged in the nylon core, a guide sleeve is sleeved with the extensible pipe, and the outer wall of the protecting layer is provided with an armour abrading layer. The flexible composite high pressure conveying pipe for petroleum and natural gas industries can bear negative pressure, has strong flexibility and is suitable for deep sea mining of petroleum and natural gas.
Description
Technical field
The utility model belongs to the conveyance conduit technical field, relates in particular to a kind of petroleum gas industrial flexible composite high pressure delivery pipe.
Background technique
The application of oil transport pipeline flexible pipe at present is more and more wider, and exploitation especially by land is poor day by day, and submarine oil exploitation proportion continues to increase the demand of ocean with flexible pipe increasing.Its structure of ocean flexible pipe of current use comprises nylon core, and the nylon core outer wall is coated with steel wire and twines enhancement layer and protective coating.The anti-negative high voltage poor performance of the ocean flexible pipe of this structure is difficult to adapt to deep-sea recover petroleum rock gas.
The model utility content
The technical problem that the utility model will solve just provides the petroleum gas industrial flexible composite high pressure delivery pipe that a kind of anti-negative high voltage performance is good, adapt to deep-sea recover petroleum rock gas.
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is: comprise nylon core, the nylon core outer wall is coated with steel wire and twines enhancement layer and protective coating, is provided with in the described nylon core by the folding steel plate interlock of pros-and-cons type and rolls the telescopic pipe that forms.
Its additional technical feature is: described telescopic pipe is with guide thimble; The outer wall of said protective coating is provided with armoured braid.
The petroleum gas industrial flexible composite high pressure delivery pipe that the utility model provides is provided with in the nylon core by the folding steel plate interlock of pros-and-cons type and rolls the telescopic pipe that forms.Telescopic pipe is 0.5 with thickness---the 1.2mm sheet metal, and adopt the folding interlock of pros-and-cons type to roll and form, both can carry negative pressure, also can bear radial pressure, axial tension and flexural stress.During variation on the composite pipe length that can also move in seabed laminar flow, geology, floating etc. brought buffering is provided, makes composite pipe have stronger toughness, adapt to deep-sea recover petroleum rock gas.And telescopic pipe is with guide thimble, makes telescopic pipe be easy to get into nylon core and nylon core is not damaged, and guide thimble adopts nylon PA material, polythene PE, polyurethane and polyether TPU class material to process.The outer wall of protective coating is provided with armoured braid, and armoured braid shield adopts 9 strands of every bundles, and the Stainless Steel Wire of single φ 1-1.2mm becomes 54 ° of 44' interlacings to form.Can bear big shearing stress, impact stress, flexural stress and transportation wearing and tearing.Joint adopts that cold-welding technique is powerful to be connected, and can effectively avoid the creep of the plastic resin layer that welding heat causes, and can effectively protect the durable stability of joint.In addition, steel wire winding enhancement layer is reverse acting spiral by two groups of adjacent layer materials and is entwined, and is not interweaved between material, can give full play to the material maximum strength.The winding number of plies is an even number, by different resistance to compression requirements, is divided into 2 layers, 4 layers, 6 layers.Protective coating adopts the anti-molten plastics of thermoplasticity, can stop the entering of Korrosionsmedium.
Description of drawings
Fig. 1 is the structural representation of the utility model petroleum gas industrial flexible composite high pressure delivery pipe;
Fig. 2 is the structural representation of telescopic pipe.
Embodiment
Below in conjunction with accompanying drawing the structure of the utility model petroleum gas industrial flexible composite high pressure delivery pipe is done further explain.
As shown in Figure 1, the utility model petroleum gas industrial flexible composite high pressure delivery pipe is followed successively by telescopic pipe 1, guide thimble 2, nylon core 3, steel wire winding enhancement layer 4, protective coating 5 and armoured braid 6 from the inside to the outside.As shown in Figure 2, telescopic pipe 1 is rolled by the folding steel plate interlock of pros-and-cons type and forms.
The petroleum gas industrial flexible composite high pressure delivery pipe that the utility model provides is provided with in the nylon core 3 by the folding steel plate interlock of pros-and-cons type and rolls the telescopic pipe 1 that forms.Telescopic pipe 1 is 0.5 with thickness---the 1.2mm sheet metal, and adopt the folding interlock of pros-and-cons type to roll and form, both can carry negative pressure, also can bear radial pressure, axial tension and flexural stress.During variation on the composite pipe length that can also move in seabed laminar flow, geology, floating etc. brought buffering is provided, makes composite pipe have stronger toughness, adapt to deep-sea recover petroleum rock gas.And telescopic pipe 1 is with guide thimble 2, makes telescopic pipe 1 be easy to get into nylon core 3 and nylon core 3 is not damaged, and guide thimble 2 adopts nylon PA material, polythene PE, polyurethane and polyether TPU class material to process.The outer wall of protective coating 5 is provided with armoured braid 6, and armoured braid 6 adopts 9 strands of every bundles, and the Stainless Steel Wire of single φ 1-1.2mm becomes 54 ° of 44' interlacings to form.Can bear big shearing stress, impact stress, flexural stress and transportation wearing and tearing.Joint adopts that cold-welding technique is powerful to be connected, and can effectively avoid the creep of the plastic resin layer that welding heat causes, and can effectively protect the durable stability of joint.In addition, steel wire winding enhancement layer 4 is reverse acting spiral by two groups of adjacent layer materials and is entwined, and is not interweaved between material, can give full play to the material maximum strength.The winding number of plies is an even number, by different resistance to compression requirements, is divided into 2 layers, 4 layers, 6 layers.Protective coating 5 adopts the anti-molten plastics of thermoplasticity, can stop the entering of Korrosionsmedium.
The utility model petroleum gas industrial flexible composite high pressure delivery pipe is not only applicable to the transfer oil rock gas, and is suitable equally in other field that needs conveyance fluid.
