Application differences of high-frequency resistance welded steel pipe

Application differences of high-frequency resistance welded steel pipe
The purpose of manufacturing the product is in order to meet certain social functional requirements, pipe production as well. At present, the welded steel pipe has been more and more used in the field of machinery, automotive, energy, large-scale engineering structure and re-processing. Take the development and application of Nippon Steel Pipe Company in the welded steel pipe field for example, its products are related to each of the major areas of industrial production.
The use of high-frequency resistance welded steel pipe is mainly small diameter structural steel pipe, tubing and casing, line pipe and boiler tubes, etc, and this need tends to classify refinement with the changes and advances in production technology and market demand.
In terms of the overall trend of steel pipe: mechanical and structural tube occupies a large proportion, and to maintain the momentum of growth; exclusive possession ratio remains at a certain level. This is closely related to manufacturing technology and its environmental and energy-saving high-strength materials for pipe, so do the leading steel manufacturing technology. Mechanical and structural pipe is right one of the main developing areas of application.
Small diameter welded steel pipe is mainly used in the field of institutional structures, automotive, petroleum, petrochemical, boiler, and high-performance products, high precision, good surface finish, good processing performance as the main direction of development; medium diameter welded steel pipe is mainly used in the field of the petroleum and petrochemical, marine areas, large engineering structures, and the high strength products, high toughness, high corrosion resistance, good weldability and security as the main direction of development. Differences on this demand will lead the medium and small diameter high-frequency resistance welded steel pipe technology tending to extend in different directions.
