Abstract
The utility model discloses a steel wire lining fluorine pipeline, including steel frame, polytetrafluoroethylene inside lining, a ETFE layer and the 2nd ETFE layer, the polytetrafluoroethylene inside lining is made by the polytetrafluoroethylene material, a ETFE layer and the 2nd ETFE layer are made by the ETFE material, steel frame becomes coiled tubular shape by the steel wire coiling, the outer cladding of steel frame has the polytetrafluoroethylene inside lining, the inside and outside both sides of polytetrafluoroethylene inside lining are provided with a ETFE layer and the 2nd ETFE layer respectively, a ETFE level is in inlayer, a ETFE layer is the same with the thickness on the 2nd ETFE layer, a ETFE layer with the ratio of the thickness of polytetrafluoroethylene inside lining is 1: 4. The utility model discloses the rigidity is strong, and hot expansion stress is little, long service life.
Description
Technical field
The utility model is related to a kind of pipeline, more particularly to a kind of steel wire Fluorine-lined pipeline.
Background technology
High temperature high vacuum pipe is needed during many Production in Chemical Plant.Common Fluorine-lined pipeline uses common pushing pipe and steel
The compound flange moulding process of pipe.Material can soften so that the rigidity of four fluorine tube drops significantly common four fluorine tube at high operating temperatures
It is low.If now there is vacuum in pipeline, common pipe can occur the deformation of creep, take out flat, block pipeline so that liquid can not by from
And increase the maintenance cost influence production of user.
Utility model content
Utility model purpose：The utility model is to solve the above problems, there is provided a kind of steel wire Fluorine-lined pipeline.
Technical scheme：A kind of steel wire Fluorine-lined pipeline described in the utility model, including in steel-wire carcass, polytetrafluoroethylene (PTFE)
Lining, the first ETFE layers and the 2nd ETFE layers；The polytetrafluoroethyllining lining is made up of polytetrafluoroethylmaterial material, an ETFE
Layer and the 2nd ETFE layers be made up of ETFE materials；The steel-wire carcass is by steel wire wound into helix；In the steel-wire carcass
It is coated with polytetrafluoroethyllining lining；The first ETFE layers and the is respectively arranged with inside and outside the polytetrafluoroethyllining lining
Two ETFE layers, the described first ETFE layers be located at innermost layer；Described first ETFE layers it is identical with the 2nd ETFE layers of thickness；Described
One ETFE layers is 1 with the ratio between the thickness of the polytetrafluoroethyllining lining:4.
Used as a kind of preferred scheme of the present utility model, the polytetrafluoroethyllining lining thickness is 3-8mm.
Used as a kind of preferred scheme of the present utility model, the steel-wire carcass is made up of stainless steel material.
Beneficial effect：The utility model compared with prior art, the advantage is that the utility model is using steel wire around city spiral shell
Coil shape, being clipped in carries out crystallization sintering in the middle of polytetrafluoroethylene (PTFE), steel wire is firmly embedded in the middle of polytetrafluoroethyllining lining so that poly- four
The rigidity of PVF liner is greatly increased, mechanical strength enhancing, flat, obscission will not be taken out, while thermal expansion stress is big
It is big to reduce, ETFE materials are molded inside and outside polytetrafluoroethyllining lining, the anti-wear performance of pipeline can be greatly improved, it is to avoid pipe
There is hard thing impurity in road in fluid, wear and tear tube wall, substantially increases service life of the present utility model, it is ensured that steel wire Fluorine-lined
The quality of pipeline.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Wherein, 1 is steel-wire carcass；2 is polytetrafluoroethyllining lining；3 is the first ETFE layers；4 is the 2nd ETFE layers.
Specific embodiment
With reference to the accompanying drawings and detailed description, the utility model is further elucidated.
Embodiment
With reference to Fig. 1, the utility model discloses steel wire Fluorine-lined pipeline, high temperature high vacuum pipe is mainly used as.This practicality is new
Type includes steel-wire carcass 1, ETFE layers 3 of polytetrafluoroethyllining lining the 2, the first and the 2nd ETFE layers 4；The polytetrafluoroethyllining lining 2
Be made up of polytetrafluoroethylmaterial material, the described first ETFE layers 3 and the 2nd ETFE layers 4 be made up of ETFE materials；The steel-wire carcass 1
Can be made up of stainless steel material, the steel-wire carcass 1 is by steel wire wound into helix；In the outer cladding of the steel-wire carcass 1
There is polytetrafluoroethyllining lining 2；The first ETFE layers 3 and second is respectively arranged with inside and outside the polytetrafluoroethyllining lining 2
ETFE layers 4, the described first ETFE layers 3 be located at innermost layer；Described first ETFE layers 3 it is identical with the 2nd ETFE layers 4 of thickness；It is described
The thickness of polytetrafluoroethyllining lining 2 is preferably 3-8mm.Described first ETFE layers 3 the ratio between with the thickness of the polytetrafluoroethyllining lining 2
It is 1:4.
Using steel wire around city helix, be clipped in carries out crystallization sintering to the utility model in the middle of polytetrafluoroethylene (PTFE), steel wire jail
Jail is embedded in the middle of polytetrafluoroethyllining lining 2 so that the rigidity of polytetrafluoroethyllining lining 2 is greatly increased, mechanical strength enhancing, will not
Flat, obscission is taken out, while thermal expansion stress is substantially reduced, ETFE materials is molded inside and outside polytetrafluoroethyllining lining 2
Material, can greatly improve the anti-wear performance of pipeline, it is to avoid there is hard thing impurity in fluids within pipes, and wear and tear tube wall, greatly improves
Service life of the present utility model, it is ensured that the quality of steel wire Fluorine-lined pipeline.
Various modifications to embodiment will be apparent for those skilled in the art, determine herein
The General Principle of justice can in other embodiments be realized in the case where spirit or scope of the present utility model are not departed from.Cause
This, the utility model is not intended to be limited to the embodiments shown herein, and is to fit to and principles disclosed herein
The most wide scope consistent with features of novelty.
