Abstract
The utility model relates to a glass reinforced plastic stainless steel compound pipe used as a pipeline. A stainless steel pipe is taken as a liner pipe. A glass fibre reinforced plastic layer is arranged outside the liner pipe. The liner pipe has an extended connection end for the convenience of connecting a pipeline. The thickness of the glass fibre reinforced plastic layer is thicker than the wall thickness of the liner pipe. The heat-insulating property of the glass fibre reinforced plastic layer is favorable for the heat insulation of the pipeline and for increasing the rigidity of the compound pipe. Because the stainless steel has higher price and thinner thickness, a stainless steel pipe is taken as a liner pipe which is thinner. Therefore, overall cost is reduced, and simultaneously requirements of easy corrosive medium are satisfied. The glass reinforced plastic stainless steel compound pipe is designed referring to pipelines which are easy to be corrupted. The glass reinforced plastic stainless steel compound pipe has performances of two pipes, and enables entire cost to be reduced.
Description
The utility model relates to a kind of pipe, particularly relates to a kind of glass fibre reinforced plastics---stainless steel composite pipe.
Pipeline is to be formed by connecting with the pipe that metal or other materials are made, and is used for conveying or discharge liquid, gas.Common have metallic conduit and a Glass Steel Tube, and wherein the Glass Steel Tube price is lower, has some performance of steel pipe, is widely used on the pipeline at present.But fiber reinforced plastic pipe is in long-term using process, is prone to agingly, and intensity is lower, and not anti-alkali corrosion connects inconvenience.At carrying different media, often need high-performance, high-intensity stainless steel pipeline, but Stainless Steel Tube costs an arm and a leg, the cost height, its thin-walled stainless steel tube intensity is little, is prone to problems such as distortion.
The purpose of this utility model is the problem that occurs at Glass Steel Tube and thin-wall stainless steel in long-term the use, and a kind of intensity, glass fibre reinforced plastics---stainless steel composite pipe that rigidity is big are provided, and can reduce the cost of pipeline, prolongs the spreadable life of pipeline.
The purpose of this utility model can reach by the following technical programs; Do bushing pipe with Stainless Steel Tube, on bushing pipe, be shaped on frp layer.
There is the connecting end of stretching out at above-mentioned single composite pipe lining Stainless Steel Tube two ends, and the thickness of frp layer is greater than the wall thickness of bushing pipe Stainless Steel Tube.This composite pipe has two pipe performances concurrently, and outer layer thickness is greater than the thickness of bushing pipe, and liner is a Stainless Steel Tube, meets the requirement of special fed sheet of a media to pipe performance, and pipeline cost is lowered relatively, thereby can realize its purpose.
The utility model is compared with above-mentioned present technology can have following advantage: owing to adopt composite pipe structure, have both the performance and the advantage of glass fibre reinforced plastics and Stainless Steel Tube.The overcoat frp layer is thicker, and do not contact, thereby, after long service life, be not corroded not by its corrosion with the medium that is transferred, thereby also just difficult aging, the long-term back of using influences less to its strength and stiffness; The good heat insulating of glass fibre reinforced plastics is made the overcoat of composite pipe with thicker glass fibre reinforced plastics, helps the insulation of pipeline; Its proportion is little, and it is light to make its body of composite pipe, easy construction.Liner is a Stainless Steel Tube, though its price is higher, wall thickness is thinner, and the relative material consumption is few; Liner is that Stainless Steel Tube is at the special media that is transferred or discharges, and does not reduce its performance after long-term the use, still has the characteristics that intensity is big, antiseptic property is strong; In addition, it is easy to connect.In a word, the two advantage embodies a concentrated reflection of on composite pipe.
Accompanying drawing is this composite pipe sectional drawing.
Below in conjunction with accompanying drawing will the utility model is described in further detail:
Shown in accompanying drawing, be used as the glass fibre reinforced plastics of pipeline---stainless steel composite pipe, adopt Stainless Steel Tube 1 to make bushing pipe, be shaped on frp layer 2 on it and form composite pipe.
Above-mentioned single composite pipe is in order to be linked to be pipeline, and there is the connecting end of stretching out 3 at the two ends of single composite pipe lining Stainless Steel Tube 1, and general the employing welded.The thickness of overcoat frp layer 2 is greater than the wall thickness of bushing pipe Stainless Steel Tube 1, and it is thicker that the thickness of overcoat is done, and helps the insulation of composite pipe, makes composite pipe have higher strength and stiffness simultaneously; And inner liner stainless steel pipe 1 is thinner what meet design requirement and do down as far as possible, and cost is lowered, and its wall thickness can be more than 1.5 millimeters.
Claims (3)
1, a kind of glass fibre reinforced plastics that is used as pipeline---stainless steel composite pipe has glass fibre reinforced plastics and Stainless Steel Tube, it is characterized in that: do bushing pipe with Stainless Steel Tube (1), frp layer (2) is arranged on it.
2, composite pipe according to claim 1 is characterized in that: single composite pipe lining Stainless Steel Tube (1) has the connecting end of stretching out (3).
3, composite pipe according to claim 1 and 2 is characterized in that: the thickness of overcoat frp layer (2) is greater than the wall thickness of bushing pipe Stainless Steel Tube (1).
