Technical Field
The utility model relates to a structure of compound steel pipe, concretely relates to wear-resisting compound steel pipe of high performance resistance to compression 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. But the existing steel pipe has poor wear resistance and pressure resistance in the using process, so that the actual using effect is influenced.
