Abstract
The technical scheme includes that the stainless steel inner tube comprises a spiral steel band, a first seam and a second seam are arranged on two sides of the steel band respectively, the first seam and the adjacent second seam are meshed with each other, a fiber reinforcing layer is arranged on the outer surface of the stainless steel inner tube, and an impact resistant layer is arranged on the outer surface of the fiber reinforcing layer. The utility model utilizes the impact resistant layer to absorb impact energy and distribute stress, thereby protecting the whole pipeline well, improving the weather resistance of the pipeline and greatly enhancing the environmental adaptability of the pipeline.
Description
Technical Field
The utility model relates to the technical field of pipelines, in particular to an impact-resistant fiber reinforced stainless steel composite pipe.
Background
In recent years, fiber reinforced composite pipelines are more and more commonly applied, have lower price than traditional pipelines and good weather resistance, and are commonly applied in the fields of drainage and water supply. Although the rigidity is good, the requirement is high during construction, the impact resistance to sharp objects is general, and particularly when the concrete is paved and backfilled as an embedded pipeline, sharp stones, metal and other hard objects impact the pipeline instantly, so that the pipeline is easy to crack or even damage, leakage events are generated, and great hidden danger and serious loss are caused.
SUMMERY OF THE UTILITY MODEL
Aiming at the problem that the surface of a fiber reinforced composite pipe in the prior art is not impact-resistant, the utility model provides an impact-resistant fiber reinforced stainless steel composite pipe.
The utility model provides the following technical scheme: the impact-resistant fiber reinforced stainless steel composite pipe comprises a stainless steel inner pipe, wherein the stainless steel inner pipe comprises a spiral steel belt, a first seam and a second seam are respectively arranged on two sides of the steel belt and are mutually meshed with each other, a fiber reinforcing layer is arranged on the outer surface of the stainless steel inner pipe, and an impact-resistant layer is arranged on the outer surface of the fiber reinforcing layer.
Preferably, the fiber reinforced layer is a fiber reinforced thermosetting plastic tube or a fiber reinforced plastic sand inclusion tube.
Preferably, the impact resistant layer is an impact resistant plastic tube or rubber sleeve.
The utility model has the beneficial effects that: the fiber reinforced layer can increase the rigidity of the pipeline, the impact resistant layer covers the outer surface of the fiber reinforced layer, the effects of absorbing impact energy and distributing stress are achieved, the whole pipeline is well protected, the weather resistance of the pipeline is improved, and the environmental adaptability of the pipeline is greatly enhanced.

Detailed Description
The embodiments of the present invention will be described in more detail with reference to the accompanying drawings and reference numerals, so that those skilled in the art can implement the embodiments of the present invention after studying the specification. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.
The utility model provides an impact-resistant fiber reinforced stainless steel composite pipe as shown in figures 1-2, which comprises a stainless steel inner pipe 1, wherein the stainless steel inner pipe comprises a spiral steel belt 11, a first seam 12 and a second seam 13 are respectively arranged on two sides of the steel belt 11, the first seam 12 and the adjacent second seam 13 are mutually meshed, a fiber reinforced layer 2 is arranged on the outer surface of the stainless steel inner pipe 1, and an impact-resistant layer 3 is arranged on the outer surface of the fiber reinforced layer 2.
The composite pipe comprises a stainless steel inner pipe, a fiber reinforced layer and an impact resistant layer which are sequentially arranged from inside to outside. The stainless steel inner pipe is formed by winding a steel belt twisted into a spiral shape, a first seam and a second seam are respectively formed on two sides of the steel belt, and as shown in fig. 2, the adjacent first seam and the second seam are mutually meshed to form a stable tubular structure. The fiber reinforced layer covers the outer surface of the stainless steel inner pipe to enhance the rigidity and the sealing performance of the stainless steel inner pipe. The impact resistant layer can be made of an impact resistant plastic pipe or a rubber sleeve and covers the outer surface of the fiber reinforced layer, so that impact of sharp objects on the fiber reinforced layer during backfilling is prevented, and the fiber reinforced layer is protected.
Preferably, the fiber reinforced layer 2 is a fiber reinforced thermosetting plastic pipe or a fiber reinforced plastic sand inclusion pipe, and has light weight, good pressure bearing capacity and strong chemical and electrical corrosion resistance.
Preferably, the impact resistant layer 3 is an impact resistant plastic tube or rubber sleeve.
The foregoing is a detailed description of one or more embodiments of the utility model, which is set forth in more detail and is not intended to limit the scope of the utility model. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the spirit of the utility model, which falls within the scope of the utility model. Therefore, the protection scope of the present patent shall be subject to the appended claims.
