Abstract
A high-expansion-ratio anti-fatigue fluorinated ethylene propylene (FEP)/ poly-fluoroalkoxy (PFA) coil pipe comprises FEP/PFA fluorine plastic pipes which are spiral. The diameter of each FEP/PFA fluorine plastic pipe is 2 millimeters to 12 millimeters, the thread ditch is 2 millimeters to 12 millimeters, and the length of each FEP/PFA fluorine plastic pipe is 100 millimeters to 1 meter. The high-expansion-ratio anti-fatigue FEP/PFA coil pipe is high in expansion ratio, fatigue resistance and capable of prolonging using length of the FEP/PFA pipe.
Description
[technical field]
The utility model relates to a kind of high stretching rate antifatigue FEP/PFA spiral coil, refers to a kind of high stretching rate antifatigue FEP/PFA spiral coil especially.Be mainly used in.
[background technique]
FEP/PFA fluorine plastic tube antiseptic property is good, resistance to pressure is high, and transparency is good and moderate, is widely used in industries such as Aero-Space, mechanical industry, petrochemical industry, is used to carry lubricant oil, fuel oil, gas etc. to have certain corrosive fluid and liquid.But the stretching rate of FEP/PFA fluoroplastic is little, fragility is bigger, in the application of reality, because conveying corrosive fluid and fluid pipeline are longer, can be caused the fatigue fracture of FEP/PFA fluoroplastic pipeline by the stress of temperature variation generation.Limited the use length of FEP/PFA fluorine plastic tube.
[summary of the invention]
To the shortcoming of existing technology, the purpose of the utility model is to provide a kind of high stretching rate antifatigue FEP/PFA spiral coil.
The utility model solves the technological scheme that its technical problem adopted: a kind of high stretching rate antifatigue FEP/PFA spiral coil, comprise the FEP/PFA fluorine plastic tube, and it is characterized in that: said FEP/PFA fluorine plastic tube dish curl.FEP/PFA fluorine plastic tube caliber is 2mm～12mm, and pitch is 2-12mm, and the length of every FEP/PFA fluoroplastic coil pipe is 100mm～1m.
Like this, utilize the flexibility and the ductility of spiral coil, the delivered length of FEP/PFA fluorine plastic tube is greatly prolonged.
The beneficial effect of the utility model is: because spiral coil has bigger flexibility, ductility and scalable performance, enlarged the use length range and the space of FEP/PFA pipe.
[description of drawings]
Below in conjunction with accompanying drawing the utility model is done further to describe.
Fig. 1 is the structural representation of the utility model.
[embodiment]
Referring to accompanying drawing, a kind of high stretching rate antifatigue FEP/PFA spiral coil of the utility model comprises the FEP/PFA fluorine plastic tube, it is characterized in that: said FEP/PFA fluorine plastic tube dish curl.
In the embodiment of the utility model, FEP/PFA fluorine plastic tube caliber is 2mm～12mm, and pitch is 2-12mm, and the length of every FEP/PFA fluoroplastic coil pipe is 100mm～1m.
The embodiment of the utility model adopts following method to implement:
1. with pack into metal shaper and fixing of the FEP/PFA that is up to the standards pipe.
2. the FEP/PFA tubing that fixes is put into heating cabinet and heat, FEP to 200～220 ℃, PFA to the 280～300 ℃ time is incubated about 20 minutes and eliminates flexural stress.
3. in heating cabinet, take out and put into the typing of water cooling pond quick cooling simultaneously.
4. remove the metal shaper, obtain goods.
Claims (2)
