Abstract
Provided is a glass fiber reinforced plastic lined with a stainless steel composite pipe with thick-walled stainless steel connectors with external threads. The glass fiber reinforced plastic lined with the stainless steel composite pipe with the thick-walled stainless steel connectors with the external thread comprises a lining layer, reinforced layers and the two thick-walled stainless steel connectors, the lining layer is a thin-walled stainless steel pipe, the two thick-walled stainless steel connectors are connected at two ends of the lining layer and the threads are arranged on outer surfaces of the two thick-walled stainless steel connectors, and the reinforced layers are arranged on surfaces of the lining layer and the inner side portion of the two thick-walled stainless steel connectors and are made of glass fiber reinforced plastics. According to the glass fiber reinforced plastic lined with the stainless steel composite pipe with the thick-walled stainless steel connectors with the external threads, through mechanical processing to the surface of the upper thick-walled stainless steel connector to manufacture a structure with the external threads, when the glass fiber reinforced plastics are wound on the glass fiber reinforced plastic lined with the stainless steel composite pipe with the thick-walled stainless steel connectors with the external threads, the binding force between the hick-walled stainless steel connectors with the external threads and the glass fiber reinforced plastic lined with the stainless steel composite pipe are strengthened, and thus the axial anti-tensile strength and the anti-distortion strength of the double-layer composite pipe are increased. Besides, the glass fiber reinforced plastic lined with the stainless steel composite pipe with the thick-walled stainless steel connectors with the external threads has the characteristics of stainless steel materials and glass fiber reinforced plastics, namely, anti-corrosion and good resistance to high temperature, and thus corrosion to the inner wall and the outer wall of the composite pipe caused by internal mediums and external environment can be avoided.
Description
Technical field
The utility model relates to a kind of frp lining stainless steel composite pipe, particularly relates to a kind of frp lining stainless steel composite pipe with outside thread heavy wall stainless joint.
Background technique
the frp lining stainless steel composite pipe is a kind of internal and external anti-corrosive multiple tube of commonly using at present, the internal layer of this pipeline is thin-wall stainless steel, the internal layer two ends connect respectively a heavy wall stainless joint, skin is made by glass fibre reinforced plastic material, production method is first two heavy wall stainless joints to be connected to thin-wall stainless steel two ends, then at the surperficial fw frp material of thin-wall stainless steel and two heavy wall stainless joint inside lines and form skin, install in process of deployment is to adopt welding method to interconnect the corresponding heavy wall stainless joint on adjacent two double-layer compound pipelines.Its advantage is to have the good corrosion of anti-inside and outside and heat-resisting ability, but shortcoming is the surperficial smoother due to the heavy wall stainless joint, therefore the position combination force that combines with glass fibre reinforced plastic material on it is relatively low, thereby when double-layer compound pipeline is subject to axial tension and circumferential torsion, this position will because of axial tensile strength and anti-twist intensity is lower easily produces layering, thereby seriously affects the quality of whole pipeline.
Summary of the invention
In order to address the above problem, the purpose of this utility model is to provide a kind of frp lining stainless steel composite pipe with outside thread heavy wall stainless joint that can significantly increase its tension and anti-twist intensity.
In order to achieve the above object, the frp lining stainless steel composite pipe with outside thread heavy wall stainless joint that provides of the utility model comprises inside liner, reinforced layer and two heavy wall stainless joints; Wherein inside liner is thin-wall stainless steel; Two heavy wall stainless joints are connected to the two ends of inside liner, and outer surface is threaded; Reinforced layer is arranged on the surface of inside liner and two heavy wall stainless joint inside lines, and it is made by glass fibre reinforced plastic material.
The thickness of described heavy wall stainless joint is greater than the thickness of inside liner.
The length A of described heavy wall stainless joint is 50mm-500mm, and thickness is 3mm-15mm.
The frp lining stainless steel composite pipe with outside thread heavy wall stainless joint that the utility model provides is that the surface of heavy wall stainless joint on it is made with externally threaded structure by machining processes, just can strengthen like this combination force between the two when being wound around glass fibre reinforced plastic material thereon, therefore can increasing axial tensile strength and the anti-twist intensity of double-layer compound pipeline.In addition, this double-layer compound pipeline still has stainless steel material, glass fibre reinforced plastic material is corrosion-resistant, resistance to high temperature is good characteristics, can prevent that therefore interior media and external environment condition are to the corrosion of the inside and outside wall of multiple tube.
Description of drawings
The frp lining stainless steel composite pipe longitudinal cross-section sectional view with outside thread heavy wall stainless joint that Fig. 1 provides for the utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the frp lining stainless steel composite pipe with outside thread heavy wall stainless joint that the utility model provides is elaborated.
As shown in Figure 1, the frp lining stainless steel composite pipe with outside thread heavy wall stainless joint that provides of the utility model comprises inside liner 1, reinforced layer 2 and two heavy wall stainless joints 3; Wherein inside liner 1 is thin-wall stainless steel; Two heavy wall stainless joints 3 are connected to the two ends of inside liner 1, and outer surface is threaded; Reinforced layer 2 is arranged on the surface of inside liner 1 and two heavy wall stainless joint 3 inside lines, and it is made by glass fibre reinforced plastic material.
The thickness of described heavy wall stainless joint 3 is greater than the thickness of inside liner 1.
The length A of described heavy wall stainless joint 3 is 50mm-500mm, and thickness is 3mm-15mm.
When needs produce that the utility model provides with the frp lining stainless steel composite pipe of outside thread heavy wall stainless joint the time, at first weld respectively one with externally threaded heavy wall stainless joint 3 at the two ends of inside liner 1, then be wound around the upper glass Steel material and form reinforced layer 2 on the inside line of inside liner 1 and two heavy wall stainless joints 3 surface, and reserve the welded joint a that length is 20mm-30mm in the outer end of each heavy wall stainless joint 3, the connection when being used for laying this double-layer compound pipeline between adjacent channel.
