a deep analysis of the differences and advantages between submerged arc welded steel pipe and high frequency steel pipe
In the field of steel pipe manufacturing, huayang steel pipe has always maintained a leading position in the industry with its rich experience and excellent technology. Among them, submerged arc welded steel pipe and high frequency steel pipe, as the two core products of the company, have their own unique characteristics and remarkable advantages, providing customers in different fields with diversified choices.
Submerged arc welding steel pipe has a unique manufacturing process, which uses flux to protect the weld and adopts arc hot melting technology with external welding wire. This welding method makes the weld neat and 1-3mm higher than the base metal, forming obvious weld bulge. In order to meet the specific needs of customers, the submerged arc welded steel pipe can be ground according to the customer's requirements before leaving the factory, leaving clear grinding marks with the grinding wheel, which not only ensures the smoothness of the weld, but also improves the aesthetics of the product. The production process of submerged arc welded steel pipe is flexible and changeable, and it can produce any specifications and wall thickness within the scope, even specifications and models that high-frequency steel pipes, spiral steel pipes and even seamless steel pipes can not produce, which makes submerged arc welded steel pipes widely used in heavy steel structure engineering and fluid pipeline engineering. Although its production cost is relatively high, compared with seamless steel pipe, the price of submerged arc welded steel pipe still has a larger preferential space, providing customers with a more cost-effective choice.
The high-frequency steel pipe is made by winding a long strip of steel into a round tube by a high-frequency welding unit and welding it straight. In the welding process, the steel at the edge of the weld is locally heated to a molten state, and the indirect grain bonding is realized after being extruded by the roller. The tube body of high-frequency steel pipe is flat and smooth, and there is no oxide scale attached, and the weld seam presents a jagged saw-like irregular shape. In order to improve the aesthetics and practicality of the products, the welds of high-frequency steel pipes will be scraped off before leaving the factory, leaving a flat and clear trace. High frequency steel pipe has the advantages of high production efficiency, narrow welding heat affected zone, beautiful welding forming and good mechanical properties, which makes it widely used in civil construction, petrochemical, light industry and other departments.
On the whole, submerged arc welding steel pipe and high frequency steel pipe have their own advantages and characteristics. Submerged arc welded steel pipe has excellent performance in specification flexibility, material adaptability and weld quality, which can meet the diversified needs of customers for high-quality steel pipes. High-frequency steel pipes, on the other hand, have more advantages in production efficiency, cost-effectiveness and aesthetics, providing customers with more cost-effective choices. Huayang Steel Pipe can provide customers with high-quality submerged arc welded steel pipes and high-frequency steel pipes with rich product categories, high-quality assurance, customized services and advanced production equipment to meet the individual needs of different customers. Whether it is heavy steel structure engineering or civil building, whether it is fluid pipeline engineering or petrochemical, light industry and other departments, Huayang Steel Pipe can provide customers with the most suitable steel pipe products and help customers achieve the success of the project.
