Description
Technical Field
The utility model relates to a structure of compound steel pipe, concretely relates to compound steel pipe with function gives sound insulation belongs to compound steel pipe technical field.
Background
The pipeline transportation has the advantages of large, continuous, rapid, economic, safe, reliable and stable transportation amount, less investment, less occupied area and low cost, and can realize automatic control. Besides being widely used for long-distance transportation of petroleum and natural gas, the material can also be used for transporting ores, coal, building materials, chemicals, grains and the like. The pipeline transportation can save the broken joints in the water transportation or the land transportation, shorten the transportation period, reduce the transportation cost and improve the transportation efficiency. The current trend in pipeline transportation is: the caliber of the pipeline is continuously increased, and the transportation capacity is greatly improved; the transport distance of the pipeline is rapidly increased; the transportation materials are gradually expanded from fluids such as petroleum, natural gas and chemical products to non-fluids such as coal and ore. However, in the use process of the existing steel pipe, a large amount of noise is generated due to the passing of fluid, and the use effect is influenced.
SUMMERY OF THE UTILITY MODEL
The utility model aims at the not enough of above-mentioned prior art, provide a compound steel pipe with sound insulation function.
The technical scheme of the utility model as follows:
the utility model provides a compound steel pipe with sound insulation function, characterized by, this compound steel pipe includes the steel of inlayer from inside to outside in proper order and moulds inner tube, middle soundproof cotton, the outer steel of skin and mould the outer tube, the outer wall of steel-plastic outer tube has evenly arranged anti-skidding ripple, adopts novel ring flange to connect between the two adjacent sections compound steel pipe.
Further, the outer surface of the steel-plastic outer pipe is coated with a wear-resistant metal layer, and the anti-skid corrugations are arranged on the wear-resistant metal layer.
Furthermore, two end faces of the novel flange plate are respectively provided with a connecting structure matched with the end face of the composite steel pipe, and a through hole matched with the inner diameter of the composite steel pipe is arranged at the middle position of the novel flange plate.
Furthermore, the connecting structure comprises four circles of convex annular limiting walls, namely a first limiting wall, a second limiting wall, a third limiting wall and a fourth limiting wall from inside to outside in sequence; the clearance between first spacing wall and the second spacing wall is used for holding the tip of steel-plastic inner tube, and the clearance between second spacing wall, the third spacing wall is used for holding soundproof cotton's tip, and the clearance between third spacing wall, the fourth spacing wall is used for holding the tip of steel-plastic outer tube.
Furthermore, the fourth limiting wall is screwed with the steel-plastic outer pipe through threads, and a sealing washer is arranged.
In the utility model, the outer surface of the steel-plastic outer pipe is coated with the wear-resistant metal layer, so that the wear resistance of the composite steel pipe is enhanced; the anti-skid corrugations are uniformly arranged on the outer wall of the wear-resistant metal layer, so that the anti-skid performance is enhanced; the sound insulation cotton is arranged in the interlayer between the steel-plastic inner pipe and the steel-plastic outer pipe, so that the buffer performance of the steel pipe after being impacted is improved, and the sound insulation effect is achieved; the setting of ring flange can play fixed soundproof cotton's effect on the one hand, and on the other hand has increased the fastness that compound steel pipe connects.
The utility model has the advantages of simple and reasonable structure, the manufacturing is easy, the combination of multiple scheme, and the wear-resisting and resistance to compression and the sound insulation performance of compound steel pipe are promoted by a wide margin, have wide market space.
