Abstract
The utility model relates to a port connection structure of a steel pipe with Teflon anticorrosion liner, in particular to a port connection structure of a steel pipe with inner and outer Teflon anticorrosion liners. The utility model is characterized in that the port of an inner Teflon pipe is longer than the port of a steel pipe and an outer Teflon liner membrane of a certain thickness is melted at the outer surface of the exposed section between the steel pipe and the inner Teflon pipe. The utility model aims to design a port connection structure of a steel pipe with inner and outer Teflon anticorrosion liners that can enhance the connection strength of the inner liner and the outer liner. Compared with the prior art, the utility model has the advantages of reliable connection, long service life and easy manufacturing, which avoids the economic loss due to short service life and meets the demands of manufactures.
Description
Technical field
The utility model relates to the port linkage structure of lining teflon anti-corrosive steel tube, the port linkage structure of the inside and outside lined steel pipe of particularly a kind of teflon.
Background technique
The inside and outside lined steel pipe of tradition teflon is made the following method of the general employing of technology: the one, on the steel pipe of regulation, twine polytetrafluoroethylene film and thermal sintering earlier; The 2nd, the polytetrafluoroethyllining lining pipe that makes is inserted in the steel pipe, and the polytetrafluoroethyllining lining tube end is heated its flange 180. The 3rd, between inside and outside lining, put into the Meltability polytetrafluorethyletubular film, again with glass tape with inside and outside lining tighten, at glass tape external application flame the liner heating is dissolved up to the Meltability polytetrafluorethyletubular film then, behind the natural cooling glass tape is pulled down, the inside and outside lined steel pipe of teflon is made and is finished.Its deficiency: the port linkage structure of the inside and outside lined steel pipe of teflon is to rely on Meltability polytetrafluorethyletubular thin layer (its thickness 0.5mm) to connect the inside and outside lining of teflon, and its intensity is very limited, and working life is shorter.Especially be higher than 150 ℃ when serviceability temperature, cold and heat succeed each other when frequent, working life is then shorter, causes certain loss for producer's ordinary production.
Summary of the invention
The purpose of this utility model is a kind of port linkage structure that can strengthen the inside and outside lined steel pipe of teflon of interior outer lining join strength of design.
In order to achieve the above object, the utility model adopts following technical solution: the port linkage structure of the inside and outside lined steel pipe of a kind of teflon, comprise steel pipe, polytetrafluoroethyllining lining pipe, teflon outer film, it is characterized in that the polytetrafluoroethyllining lining tube opening is long more a bit of than steel pipe port, expose at steel pipe and polytetrafluoroethyllining lining pipe that fusion simultaneously is connected certain thickness teflon outer film on the outer surface of pipeline section.
Because directly clinkering one-tenth is whole under high temperature, high pressure with the inside and outside lining of teflon, the steel pipe port part forms interior outer lining tie layer, and its join strength is equal to parent, and reliability strengthens greatly, and obviously increase working life.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described in further detail.
Fig. 1 is the structural representation of present embodiment.
Embodiment
As shown in Figure 1, present embodiment comprises steel pipe (2), polytetrafluoroethyllining lining pipe (1), teflon outer film (3).Polytetrafluoroethyllining lining pipe (1) port is long more a bit of than steel pipe (2) port, this segment length is 25-35mm, steel pipe (2) port outer surface is a level and smooth chamfering, being convenient to the teflon outer film seamlessly transits, fusion is connected certain thickness teflon outer film (3) when steel pipe (2) and polytetrafluoroethyllining lining pipe (1) expose on the outer surface of pipeline section, make steel pipe (2) port part form in outer lining tie layer (4).
During manufacturing, insert the polytetrafluoroethyllining lining pipe made in the steel pipe and stretch out the about 25-35mm of steel pipe port, and in the polytetrafluoroethyllining lining port, put into supporting mould; On the steel pipe and on the polytetrafluoroethyllining lining pipe that stretches out, twine polytetrafluoroethylene film to certain thickness; Then the inside and outside lined steel pipe of the teflon of making is put into stove heat-agglomerating, be fused together fully up to the inside and outside lining of teflon.After treating natural cooling, take out the mould that is used to support in the port, get final product.
In sum, the utility model compared with prior art has the following advantages:
1, the reliability of bonding strength strengthens.
2, obviously increase service life, avoided sending out because of short economic loss in service life Give birth to.
3, manufacturing process is simple and convenient.
Claims (3)
1. the port linkage structure of the inside and outside lined steel pipe of a teflon, comprise steel pipe (2), polytetrafluoroethyllining lining pipe (1), teflon outer film (3), it is characterized in that polytetrafluoroethyllining lining pipe (1) port is long more a bit of than steel pipe (2) port, expose at steel pipe (2) and polytetrafluoroethyllining lining pipe (1) that fusion simultaneously is connected certain thickness teflon outer film (3) on the outer surface of pipeline section.
2. the port linkage structure of the inside and outside lined steel pipe of teflon according to claim 1 is characterized in that steel pipe (2) port outer surface is a level and smooth chamfering.
3. the port linkage structure of the inside and outside lined steel pipe of teflon according to claim 1 is characterized in that the length that PVF internal lining pipe (1) stretches out the steel pipe port is 25-35mm.
