Description
Technical field
The utility model relates to a kind of Stainless Steel Tube, particularly a kind of petrochemical industry duplex phase stainless tube.
Background technique
Duplex phase stainless tube is widely used in the industrial fields such as petrochemical equipment, seawater and sewage treatment equipment, oil and gas pipelines, papermaking equipment.It has the advantages that yield strength is high, expansion coefficient is low.
Although duplex phase stainless tube has advantages of many, but in having the operating mode of Korrosionsmedium, petrochemical industry etc. works for a long time, also can make it occur the phenomenon of corrosion failure, at present, for the duplex phase stainless tube using in petrochemical industry, only rely on itself corrosion resistance cannot meet the needs of use, the calculating that can only slightly walk its service time, then within this time period, it is changed, just can guarantee the use of whole pipeline.
Summary of the invention
The deficiency existing for prior art, the utility model provides a kind of good corrosion resistance, petrochemical industry duplex phase stainless tube simple in structure.
For achieving the above object, the utility model provides following technological scheme: a kind of petrochemical industry duplex phase stainless tube, include body, in body, be provided with passage, the axial two ends of passage are provided with construction opening, it is characterized in that: anticorrosive PTFE layer has been sticked on the inwall of described body passage, the axial two ends of this anticorrosive PTFE layer extend to respectively the axial construction opening place of body, and anticorrosive PTFE layer is provided with the flange with the laminating of the axial both ends open of body place end face, between the inwall of anticorrosive PTFE layer and body passage, by dismountable link, be connected, in the passage of body, be provided with the filter assemblies that can be connected with the dismounting of anticorrosive PTFE layer.
Adopt technique scheme, by anticorrosive PTFE layer is set on the inwall at body passage, can prevent from being avoided body directly to contact by the Korrosionsmedium of process in body passage, make body protected, extend its working life; Between anticorrosive PTFE layer and body, removably connect is for convenient, anticorrosive PTFE layer to be changed, after using for a long time, anticorrosive PTFE layer also can be corroded wearing and tearing, now only need be by anticorrosive PTFE layer by removing and change in body, simple in structure, easy to operate; The setting of filter assemblies can be implemented to filter to medium, removes the impurity in medium.
The utility model is further set to: link includes the magnet on the inwall that is attached at body passage and is embedded in anticorrosive PTFE layer and the magnetic mutual with magnet.
Adopt technique scheme, easy accessibility is set like this, simple in structure, and low processing cost.
The utility model is further set to: filter assemblies includes and is inserted in the installing frame in passage and is arranged in the filter screen in installing frame, and installing frame is provided with some grafting bars, and anticorrosive PTFE layer is provided with the inserting groove with this grafting bar adaptation.
Adopt technique scheme, easy accessibility is set like this, simple in structure.
Below in conjunction with accompanying drawing, the utility model is further described.
Accompanying drawing explanation
Fig. 1 is the utility model embodiment's structural representation;
Fig. 2 is the I portion enlarged diagram of Fig. 1.
Embodiment
As Fig. 1, a kind of petrochemical industry duplex phase stainless tube shown in Fig. 2, include body 1, in body 1, be provided with passage 11, the axial two ends of passage 11 are provided with construction opening 12, anticorrosive PTFE layer 2 has been sticked on the inwall of body 1 passage 11, the axial two ends of this anticorrosive PTFE layer 2 extend to respectively the axial construction opening of body 1 12 places, and anticorrosive PTFE layer 2 is provided with the flange 21 with the axial both ends open 12 places end face laminating of body 1, between the inwall of anticorrosive PTFE layer 2 and body 1 passage 11, by dismountable link 3, be connected, in the passage 11 of body 1, be provided with the filter assemblies 4 that can be connected with 2 dismounting of anticorrosive PTFE layer.In such scheme, by anticorrosive PTFE layer 2 is set on the inwall at body 1 passage 11, can prevent from being avoided body 1 directly to contact by the Korrosionsmedium of body 1 passage 11 interior processes, body 1 is protected, extend its working life; Between anticorrosive PTFE layer 2 and body 1, removably connect is for convenient, anticorrosive PTFE layer 2 to be changed, after using for a long time, anticorrosive PTFE layer 2 also can be corroded wearing and tearing, now only anticorrosive PTFE layer 2 need be changed by the interior dismounting of body 1, simple in structure, easy to operate; The setting of filter assemblies 4 can be implemented to filter to medium, removes the impurity in medium.
In the utility model embodiment, link 3 includes the magnet 31 on the inwall that is attached at body 1 passage 11 and is embedded in anticorrosive PTFE layer 2 and the magnetic 32 mutual with magnet 31.It should be noted that, link 3 also can be Bond, but comparatively inconvenience of its dismounting, thus the utility model preferably the former.
In the utility model embodiment, filter assemblies 4 includes the installing frame 41 being inserted in passage 11 and is arranged in the filter screen 42 in installing frame 41, installing frame 41 is provided with some grafting bars 411, and anticorrosive PTFE layer 2 is provided with the inserting groove 22 with these grafting bar 411 adaptations.
