Description
Technical field
The present invention relates to a kind of pipework, particularly relate to the connecting means of socket joint sealed glass steel pipeline.
Background technique
Fiber reinforced plastic pipe has been come out more than 50 year, owing to the chemical stability of its resin material is widely used, especially has serious acid, alkali, salt, the chemical pipeline of severe corrosive, oil and gas pipes, obtain increasing extensive use in the pipework in field, oil field, U.S.'s fiber reinforced plastic pipe of more than 00 ten thousand kilometers of application 1s in each oil field wherein, and annual speed with 5%～10% is constantly increasing progressively, Japanese is big, all use fiber reinforced plastic pipe in the water supply line of medium caliber more than 25%, the various water deliverys of Middle East, blowdown, desalination of sea water and mordant industrial pipeline almost all adopt fiber reinforced plastic pipe.China also begins to widely apply fiber reinforced plastic pipe to come the substituted metal pipeline at each elephant, used more than 4000 kilometer by each oil field, the whole nation in the end of the year 2003, only Daqing oil field has been used more than 800 kilometer and annual all at the application quantity of Glass Steel Tube that is doubled and redoubled from now on.Because the corrosion-resistant characteristic of fiber reinforced plastic pipe has surmounted various metallic conduits, it not only has good anti-corrosion to pipeline internal medium, and the external environment condition that severe corrosive soil or highly corrosive are arranged is all had good resistance.Because its thermal conductivity only is 1% of a steel, therefore has good heat insulating ability; Because its inner wall smooth, the medium fluid resistance is little in the pipe, non-scaling, and wax deposition not, the many advantages of work such as easy cleaning, and extraordinarily pipework such as petrochemical industry and oil field, ocean are selected for use in a large number.
But the connectivity problem of fiber reinforced plastic pipe is a headachy thing always, does not have a kind of energy to realize absolutely leak free reliable connecting means all the time.The glass pipe connecting means of widespread usage at present divides two kinds, a kind of small-bore Glass Steel Tube that is diameter less than DN200, mostly adopt screw thread screwed connection method, the screw thread screwed connection requires screw thread should play the huge pulling force of bearing pipeline axial, bear the connection sealing under the high pressure again, prove through engineering practice for many years, thisly be threaded in that to bear the axial tension aspect no problem, but obvious some deficiency in sealing, reason is to be threaded to want to realize sealing, it is high that the processing quality of fit of necessary its intermeshing male and female screw thread is wanted, especially to high pressure pipe line require higher, and of this material of glass fibre reinforced plastics itself is by the combination of glass fiber and epoxy resin, when when Glass Steel Tube termination outer surface carries out the grinding screw thread, cut off the glass fibre that a lot of layers radially twine, this just makes the Facing material of each screw thread teeth can not reach unified even degree of compaction, so it is just not strange to occur seepage under high pressure yet.Another kind is that the on-the-spot glass fibre cloth that twines adds the on-the-spot bonding method of smearing resin, this method has plenty of and has made the short tube jacket casing in advance and be connected on two pipe terminations that connect, earlier spread resin glue, again the jointing place of socket is added the glass fibre cloth winding with resin and seal in pipe termination appearance.Have plenty of and add resin glue at the seam crossing of two butt tubes with glass fibre cloth and twine to smear and seal connection, this scene twines smears very trouble of combined techniques construction, especially almost can't construct cold winter in the north, and construction quality is undesirable, the leak-down rate of connection is than higher.Therefore though Glass Steel Tube is compared with metal tube, in chemical industry and oil and gas pipes, account for and have great advantage, owing to the connectivity problem of Glass Steel Tube fails to be well solved always, also influenced Glass Steel Tube and applied widely.
For the nothing that solves above-mentioned Glass Steel Tube is leaked connectivity problem, both at home and abroad the expert seeks solution invariably painstakingly with relevant manufacturer, but do not see that for a long time suitable design finished by development, and common product does not have a kind of suitable structure to address the above problem, and this obviously is the problem that the anxious desire of relevant dealer solves.
In view of above-mentioned existing Glass Steel Tube connects existing problem, the inventor is engaged on the practical experience basis of pipeline professional work for many years in summary, through prolonged and repeated innovation research, design repeatedly and pilot sample also thresh the test of various performance tests and engineering simulation to sample, finally in multiple design proposal, selected the sealing of spigot and socket type glue ring, the more satisfactory Glass Steel Tube connecting means of flange locking, and at the characteristics of Glass Steel Tube preparation process, designed the processing mode of three kinds of flange plate, can make Glass Steel Tube manufacturer select to be suitable for the flange plate structure of oneself according to the characteristics of own product processing technique.
The Glass Steel Tube that the Glass Steel Tube connecting means (being designated hereinafter simply as " connecting means of socket joint sealed glass steel pipe ") of spigot and socket type glue ring sealing flange locking is adapted to various calibers, various medium, various working pressure, all temps and various working environments connects, did performance test thousands of times, no matter the test of its water tightness and tightness or stretching resistance all can both reach design objective, reliable in quality, none leakage.Construction and installation are very convenient, fast, without any need for machinery, save the labour force during installation, no matter how abominable installation environment, not influencing normally carrying out of piping erection engineering, is one of mounting technique method of present optimal fiber reinforced plastic pipe in the world.
