Product Description Product DescriptionProduction process of welded pipes1. Material preparation: Commencing with the fundamental phase, the creation of welded pipes involves preparing a rich variety of materials, including wide steel strips, hot-rolled steel strips, and cold-rolled steel strips, establishing a solid cornerstone for quality. These essential materials undergo precision cutting, leveling, and meticulous cleaning in adherence to stringent process requirements, ensuring that they surpass the quality demands of the finished welded pipes.2. Curling forming: The carefully processed steel strip is expertly transformed into a smaller diameter tube through a sophisticated curling machine, paving the way for the subsequent stages of pipe creation.3. Welding process: Utilizing cutting-edge high-frequency induction welding or resistance welding techniques, the curled tube is seamlessly turned into an extended, robust welded pipe.4. Steel annealing: The critical phase of steel pipe annealing treatment follows, skillfully reducing the hardness while minimizing both the stress level and internal stress, enhancing the integrity of the finished welded pipe.5. Size cutting: The elongated welded pipe is then precisely cut to the required lengths, tailored meticulously according to exacting process specifications.6. Fine repair process: A meticulous fine repair phase ensues, involving sophisticated straightening, trimming, processing, and other intricate processes, refining the cut welded pipe to perfection.7. Coating treatment: Depending on the intended usage environment, the outer wall of the welded pipe receives a specialized coating, significantly enhancing its resistance to corrosion, wear, and other environmental factors.Application fields of welded pipes1. Construction field: As indispensable building materials, welded pipes find their extensive application in constructing building structures, steel frameworks, pipelines, power poles, and highway guardrails, among others.2. Automotive manufacturing field: A vital player in automotive manufacturing, welded pipes contribute to the creation of vehicle frames, chassis, exhaust systems, and more, signifying their integral role in the industry.3. Industrial manufacturing field: Welded pipes are pivotal in industrial manufacturing sectors, prominently including machinery, shipbuilding, and aerospace, where their outstanding strength and corrosion resistance are highly valued.In brief, welded pipes stand as a cornerstone in the realm of metal materials, boasting diverse production processes and an extensive array of application fields. The intricate process of manufacturing these welded pipes demands meticulous, unwavering control to assure the superior quality of the finished products. In terms of application, the scope of welded pipe usage is ever-expanding, heralding a promising market horizon filled with vast opportunities.Detailed Photos Product ParametersShapeRectangular:20*30-600*800mmSquare:20*20-600*600 mmThickness1.0-35 mmStandardGB/T3094-2000 GB/T6728-2002ASTM A500 JIS G 3466DIN EN 10210or according to customers' requirement.MaterialQ195,Q235,Q275,Q345,20#,45#,S235,S355St33,St37,St52A500,A513,A106,A36TechniqueHot Rolled, Cold Rolled,ERW, High-frequency welded, ExtrudedCertificationISO9001SurfaceBared, Oil, Galvanized, PaintLength6m, 12m, or according to customers' requirementsUsageMachinery manufacture, Roads and Bridges,Construction, TransportationIn order to make best quotation, Please kindly indicate length, width, thickness and the standard, material you required.
