Abstract
The utility model relates to a glass fiber reinforced plastic pipeline connected with a steel flange, which comprises a glass fiber reinforced plastic pipeline, steel pipes and flanges, wherein both ends of the glass fiber reinforced plastic pipeline are formed by combining an inner lining layer and a structure layer. The two steel pipes are buried in composite layers at both of the two ends of the glass fiber reinforced plastic pipeline, and the two flanges are respectively welded at the outer ends of the two steel pipes. The flanges can be fixing flanges or movable flanges. The external surface of each steel pipe is extended with skidproof barbs. The welding positions of the flanges and the steel pipes are filled with inner lining material made of glass fiber reinforced plastic, so the utility model has the advantages that sealing performance is good, and voltage resisting capability is increased to more than 60 kilograms, pipeline connection is firm, the pipeline is convenient to install, and the performance of the original glass fiber reinforced plastic pipeline is kept. The utility model can be widely used in important industrial field, such as chemical industry, a power plant, municipal engineering, sewage treatment, etc., and especially, the utility model has obvious ascendancy in discharging water, filling pulp, pumping gas, etc. for a coal mine.
Description
Technical field
The utility model relates to a kind of pipeline, refers in particular to the fiber reinforced plastic pipe that a kind of steel flange connects.
Background technique
Glass fibre reinforced plastics is a kind of to mould the infant industry material of Dai Gang, it is with light weight, specific strength height, corrosion-resistant, tangible advantages such as surface friction drag is little, long service life, be widely used in essential industry fields such as chemical industry, power plant, municipal engineering, sewage treatment, especially the item industrial occasions such as draining, slip casting and gas pumping in the colliery are widely used especially.
Fiber twines and strengthens the thermosetting resin pressure tube, be a kind of in the glass fiber reinforced plastics product, it will have the winding sand of tension force to be wrapped on the core by twining curve with Stetch Wrapping Machine, the manual fiber reinforced plastic pipe of twining of the strength ratio of its tube wall strengthens greatly, but no matter the anti-pressure ability of tube wall has much, the pressure-bearing of glass fibre reinforced plastics flange has only 16 kilograms, can only use as low pressure pipeline.Because during greater than 90 kilograms, screw enters in the flange disk body screw on the glass fibre reinforced plastics flange, does not have the effect of two flanges of tight connection at distortion power.In addition in carrying and unloading process, glass fibre reinforced plastics flange sensitive for damages, these have all limited the widely-used of fiber reinforced plastic pipe.
Summary of the invention
The purpose of this utility model is: the steel flange that provide a kind of good seal performance, voltage endurance capability is strong, the pipeline connection is firm, easy for installation, does not influence former tube performance connects fiber reinforced plastic pipe.
For reaching the technological scheme that this purpose takes be: the fiber reinforced plastic pipe that a kind of steel flange connects, comprise fiber reinforced plastic pipe, steel pipe (1) and flange (2), the two ends of fiber reinforced plastic pipe are composited by inside liner (3) and construction layer (4), two steel pipes (1) are embedded in respectively in the composite bed at fiber reinforced plastic pipe two ends, and two flanges (2) are welded on the outer end of two steel pipes (1) respectively.The outer surface of steel pipe (1) is extended with the hangnail of projection, or is welded with steel wire, or is welded with the band steel.When flange (2) is welded on the end of steel pipe (1), be formed with concave station between the two, and be filled with the frp lining material.
The purpose of this utility model can also be achieved through the following technical solutions:
Flange (2) can be fastening flange, or is loose flange.
Compared with prior art the utility model has the advantages that:
1, good seal performance: because and the steel pipe of flange welding be to be embedded between inside liner and the construction layer by anti-skidding hangnail, be filled with the frp lining material in the concave station of flange and steel pipe weld, it is airtight that steel flange is connected with fiber reinforced plastic pipe, also realized docking of liner and liner when pipeline links to each other.
2, voltage endurance capability is strong: because between the steel flange when interconnecting, distortion power during its clamping bolt improves, connect closely, the whole voltage endurance capability that makes pipeline is by bringing up to greater than 60 kilograms less than 16 kilograms, pressure pipe road ranks during the application area of fiber reinforced plastic pipe is expanded to.
3, flange is not fragile: owing to adopt steel flange to connect, be difficult for making flange to be damaged in carrying, dismounting and work progress, the reusability of pipeline improves.
4, easy for installation: as owing to can adopt fastening flange, also can to adopt loose flange, make and align mounting hole when interconnecting between the flange easily.
5, kept former tube performance:, do not influence the advantage of bare glass steel pipeline in the glass fibre reinforced plastics body because medium still just flows in the pipe.

Fig. 1 is the structural representation that the utility model connects by fastening flange.
Fig. 2 is the structural representation that the utility model connects by loose flange.
Embodiment
Embodiment 1:
As shown in Figure 1, a kind of fiber reinforced plastic pipe that connects by fixing steel flange, comprise fiber reinforced plastic pipe, steel pipe (1) and flange (2), the two ends of fiber reinforced plastic pipe are composited by inside liner (3) and construction layer (4), two steel pipes (1) are embedded in respectively in the composite bed at fiber reinforced plastic pipe two ends, and two flanges (2) are welded on the outer end of two steel pipes (1) respectively.The outer surface of steel pipe (1) is extended with the hangnail of projection.When flange (2) is welded on the end of steel pipe (1), be formed with concave station between the two, and be filled with the frp lining material.
Working process of the present utility model is: make one long 8 meters, internal diameter is the fiber reinforced plastic pipe of 100mm, at first selecting internal diameter for use is that 108mm, external diameter are that 114mm, length are the steel pipe (1) of 20mm, at its outer surface car 3 circle hangnails is arranged, to prevent composite bed and steel pipe slippage.With internal diameter is that the flange (2) of 115mm is socketed in the distolateral of steel pipe, makes flange and steel pipe wrong 5mm outside axial direction, forms concave station, and with flange and steel pipe along the border firm welding.Again two flanges are inserted in the centre of core, the glass needled mat inside liner (3) of impregnated with resin is wrapped in two ends on the core, its coiling length overlaps flange (2) by the centre to two ends then greater than the about 50mm of length of steel pipe (1), and inside liner (3) is tamped the concave station of flange and steel pipe fitting.After inside liner (3) solidifies, in the outer wall fw frp construction layer of steel pipe (1) and inside liner (3).Unnecessary resin with flange (2) outerplanar concave station place polishes at last, forms the fiber reinforced plastic pipe finished product that steel flange connects after the demoulding.Identical fiber reinforced plastic pipe connects by steel flange, has good airproof performance, non-corrosive, is connected firmly, intensity height, characteristics such as not fragile, brings up to more than 60 kilograms for 16 kilograms when the pipeline pressure after its long distance connects can be connected by the glass fibre reinforced plastics flange.
