Description

A kind of flange connects inner liner compound pipe
Technical field
The utility model is related to technical field of pipeline connection, specifically a kind of flange connection inner liner compound pipe.
Background technology
In daily life or production process, the tubing of water delivery, oil transportation etc. is required for certain connection member by their phases Connect and seal, have various connection to tubing such as plastic cement, metal, PAP or steel-plastics composite pipes at present Structure, these structures connected have the shortcomings that certain:Plastic pipe, plastic-aluminum steel-plastics composite pipe are easy to old when being bonded using glue Change, fastness is poor, sealing is poor, small-caliber metallic using easy-to-rust seepage during the connection such as screw thread, welding, dismount it is inconvenient, need to Special disassemblerassembler, cost are high, and bore metal pipe then dismounts inconvenient, complicated, profile when being connected using special joint Greatly unsightly, it is and all poor in the presence of sealing is easily caused when installing imprudence or inadequate precision.
Therefore, to overcome the shortcomings of that above-mentioned technology designs a simple in construction, convenient disassembly, good airproof performance, connection A kind of solid and reliable flange connection inner liner compound pipe, exactly inventor's problem to be solved.
Utility model content
In view of the shortcomings of the prior art, the purpose of this utility model is to provide a kind of flange connection inner liner compound pipe, and it is tied Structure is simple, convenient disassembly, good airproof performance, firm and reliable connection.
The utility model solves the technical scheme that its technical problem used:A kind of flange connects inner liner compound pipe, its Including carbon steel layer, polyethylene layer, the carbon steel layer outer layer is to be provided with PE flange sleeves, institute on polyethylene layer, the polyethylene layer State polyethylene layer end and be provided with boss, the PE flange sleeves and boss are in mating connection, the opposite side and metal of the boss Flange is connected, and the metal flange is provided with weld pad with carbon steel layer junction, between the PE flange sleeves and metal flange It is connected by bolt, nut, pad is provided between metal flange and the PE flange sleeve.
Further, it is provided with anti oxidation layer at the pipe joint of the metal flange.
The beneficial effects of the utility model are:
1st, the utility model is simple in construction, convenient disassembly, good airproof performance, firm and reliable connection, when pipeline is connected, by PE methods Orchid set is placed on the outside of polyethylene layer pipe, is connected by the boss of PE flange sleeves and polyethylene layer end head after welding, And metal flange is connected by welding with carbon steel pipe, after metal flange is connected by bolt with PE flange sleeves, revolved with nut Fasten, connection is reliable, the pad set between metal flange and PE flange sleeves can improve the sealing of its connection, prevent Leak when using.During dismounting, bolt only need to be unscrewed, PE flange sleeves and metal flange are separated, convenient and swift.
Brief description of the drawings
Fig. 1 is the utility model structural representation.
Description of reference numerals:1- polyethylene layers;2- bolts;3- nuts;4- pads;5- weld pads;6- carbon steel layers;7- boss; 8-PE flange sleeves;9- metal flanges.
Embodiment
With reference to specific embodiment, the utility model is expanded on further, it should be appreciated that these embodiments are merely to illustrate this Utility model rather than limitation scope of the present utility model.In addition, it is to be understood that reading the content of the utility model instruction Afterwards, those skilled in the art can make various changes or modifications to the utility model, and these equivalent form of values also fall within application Appended claims limited range.
It is the utility model structural representation, a kind of flange connection inner liner compound pipe of the structure, including carbon steel layer referring to Fig. 1 6th, polyethylene layer 1, the outer layer of carbon steel layer 6 is to be provided with PE flange sleeves 8 on polyethylene layer 1, polyethylene layer 1, and the end of polyethylene layer 1 is set Boss 7 is equipped with, PE flange sleeves 8 and boss 7 are in mating connection, opposite side and the metal flange of boss 7 are connected, metal flange The junction of carbon steel layer 6 is provided with weld pad 5, is connected between PE flange sleeves 8 and metal flange by bolt 2, nut 3, gold It is provided between category ring flange 9 and PE flange sleeves 8 at pad 4, the pipe joint of metal flange 9 and is provided with anti oxidation layer.
When pipeline is connected, PE flange sleeves 8 are placed on to the outside of the pipe of polyethylene layer 1, by PE flange sleeves 8 after welding with gathering The boss 7 of the end head of pvdf layer 1 is connected, and metal flange 9 is connected by welding with carbon steel pipe, and metal flange 9 leads to Cross after bolt 2 is connected with PE flange sleeves 8, be tightened with nut 3, connection is reliable, between metal flange 9 and PE flange sleeves 8 The pad 4 of setting can improve the sealing of its connection, prevent leak when in use.During dismounting, only bolt 2, PE flanges need to be unscrewed Set 8 is separated with metal flange 9, convenient and swift.
