Description
One, technical field
The utility model relates to a kind of 12 cun two framework layer high-strength polyurethane flexible pipes, is a kind of low temperature resistant, two framework layer polyurethane flexible pipes of high-strength polyurethane.
Two, background technique
The flexible pipe product generally is made up of outer glue-line, framework layer and inner glue layer; Can be divided into following several by structure: fabric hose, spiral rubber hose, braided construction hose; Can be divided into rubber hose, thermoplastic elastomer hose and flexible pipe of composite material by the material formation.
1, fabric hose: the adhesive plaster of certain width or rubberized cord and film are wrapped on the metal frame according to the certain rules bar, odd number fiber reinforcement layer is opposite with even numbers fiber reinforcement layer winding direction, fiber reinforcement is counted more layer by layer, causes the wall thickness of sebific duct to increase, and bending radius is big, folding and curling difficulty, volume is big, and transportation is inconvenient, and adhesive plaster or rubberized cord intensity are low relatively, can not production high strength, bigbore rubber pipe; Be subjected to the restriction of vulcanizing equipment, the folder stringing can only be produced the sebific duct below 50 meters.
2, spiral rubber hose: spiral rubber hose has fiber spiral rubber hose and wire spiral rubber hose; The single fiber intensity of fiber spiral rubber hose is low, and poor fatigue properties can't production high strength, bigbore sebific duct; The framework material of wire spiral rubber hose is steel wire, and the steel wire common intensity is far above fiber, so wire spirally-wound hose compressive strength height, but the hardness of sebific duct is big, and the folding and difficulty of curling can not be produced heavy caliber winding steel wire sebific duct continuously.
3, braided construction hose: braided construction hose has textile braided hose and metal wire knitted sebific duct; Fibrage can weave the endless pipe, and fiber strength is low can not to weave high strength, bigbore sebific duct; Wire braided hose can weave the multilayer endless, but can not weave bigbore wire braided hose.
4, polyurethane tube: the polyurethane flexible pipe is coated in polyurethane (TPU) pellet in skeleton (pipe) fabric by expressing technique is disposable, outer two surfaces, a kind of thermoplasticity flexible pipe that forms, this flexible pipe has higher intensity, its sebific duct is a kind of nontoxic, environmental protection, ageing-resistant good characteristics, and it is strong to have applicability, development potentiality is very big, the starting evening of domestic polyurethane flexible pipe, the producer that produces has only three families, producing all is some small-bore polyurethane tubes below 5 cun, bigbore polyurethane tube is just under development, a spot of heavy caliber polyurethane tube all is double ends double weft structures, radially is difficult for expanding and distortion with weft direction, and polyurethane tube caliber and metal joint gap are big, sebific duct and and metal joint can not overlap fully, easily produce fold, flexible pipe uses clip not seal fully, but the seepage phenomenon appears in capsule; Polyurethane tube caliber and metal joint gap are little, and polyurethane tube and metal joint are installed difficulty.
Three, model utility content
The purpose of this utility model is that above-mentioned flexible pipe product weight is big, crooked in order to overcome, distortion, folding difficult, bearing strength is low, poor performance at low temperatures, defectives such as production length is restricted, a kind of 12 cun two framework layer high-strength polyurethane flexible pipes are provided, its have the intensity height, low temperature resistant, can curl and polyurethane flexible pipe that folding property is good.
The purpose of this utility model is achieved like this: it comprises: cover in the flexible pipe framework layer, in the flexible pipe framework layer, the overcoat connecting line, flexible pipe framework layer overcoat, the sebific duct inner glue layer, the outer glue-line of sebific duct is formed, cover is by in the flexible pipe framework layer in the flexible pipe framework layer, the overcoat connecting line is connected with flexible pipe framework layer overcoat, constitute two framework layers, cover connects the sebific duct inner glue layer in the flexible pipe framework layer, flexible pipe framework layer overcoat connects the outer glue-line of sebific duct, cover and flexible pipe framework layer overcoat in the described flexible pipe framework layer are made by certain Weaving pattern by its braiding warp and braiding parallel, and described Weaving pattern can be double ends or double weft or twill pattern.
The utlity model has higher-strength, cryogenic property good, yielding, can curl and fold, length can be according to user's requirement production; The inside and outside glue selection intensity of flexible pipe height, oil resistance excellence, the polyether-type TPUE that cryogenic property is good; The intensity of flexible pipe is mainly born by the made-up belt framework material, the framework material of made-up belt is selected particular importance, consider advantage such as polyester fibre has that Young's modulus is big, intensity is high, damp-suction is low, light ageing in anti-day, high temperature resistant, anti-low temperature are good from combination property aspects such as intensity
The two framework layer high-strength polyurethane flexible pipes of 12 cun of the utility model solve in particular cases the demand to high-strength pipe and the strong pipe of superelevation; That 12 cun two framework layer high-strength polyurethane flexible pipes have is in light weight, can curl and fold, and reservoir volume is little, transports and easy to use, and onsite moving does not need main equipment; The length of 12 cun polyurethane flexible pipes can be carried out big produced in lengths according to user's demand, flexible and the distortion of this pipe, can use in the different region of circumstance complication and lay, be not subjected to the restriction of landform, have good freedom, lay fast, simple and convenient, without special messenger's training, can operate, these 12 cun polyurethane flexible pipe sebific ducts can be used for the malleation of liquid under the industry complex environments such as oil, chemical industry and carry.
