Medium-thick wall high-frequency welded pipe: The wall thickness is generally between 3.0mm and 10.0mm.
Thick-wall high-frequency welded pipe: The wall thickness is generally above 10.0mm.
Classification by purpose:
High frequency welded pipe for structure: used for buildings, bridges and other structures.
High frequency welded pipe for fluid transportation: used for conveying fluids such as water, oil, and gas.
High frequency welded pipe for machinery: used for parts and accessories of mechanical equipment.
Classification by welding method:
Straight seam high frequency welded pipe: The welded joint is straight and suitable for most applications.
Spiral high frequency welded pipe: The welded joint is spiral-shaped and suitable for large diameter pipes.
Advantages
High production efficiency: High-frequency welding process can complete welding quickly, and its production efficiency is significantly higher than that of traditional welding methods, which is suitable for large-scale production.
Good welding quality: During high-frequency welding, the strength and sealing of the welding joint are better, the weld is uniform, and the occurrence of defects is reduced.
High material utilization rate: In the production process of high-frequency welded pipes, the material utilization rate is high, which reduces the generation of waste and reduces production costs.
Strong customizability: High-frequency welded pipes can be customized with different outer diameters, wall thicknesses and materials according to customer needs to meet diverse application requirements.
Wide adaptability: High-frequency welded pipes are suitable for a variety of materials (such as carbon steel, stainless steel, alloy steel, etc.) and can be used in different environments and conditions.
Good mechanical properties: The welded joints of high-frequency welded pipes have good mechanical properties and can withstand greater pressure and load.
Various surface treatments: High frequency welded pipes can undergo a variety of surface treatments (such as galvanizing, spraying, pickling, etc.) to improve their corrosion resistance and aesthetics.
Environmental protection: The high-frequency welding process is relatively environmentally friendly and reduces the emission of welding smoke and harmful gases.
Production process
Raw material preparation:
Choose suitable steel strip or steel plate as raw material, usually cold-rolled or hot-rolled carbon steel, stainless steel or alloy steel.
Cutting:
Cutting raw materials into required width and length for subsequent forming and welding.
Molding:
Forming machines are used to roll the cut strip or sheet into a tube. This process is usually done by passing it through several forming rollers, which gradually bend the material into the tube shape.
High frequency welding:
The formed pipe is welded by a high-frequency welding machine. The high-frequency current generates heat on the contact surface of the pipe, causing the material to melt and combine together at the contact point to form a weld.
Welding seam treatment:
After welding, the weld may be cooled and shaped to ensure the quality of the weld and the appearance of the pipe.
Annealing (optional):
Annealing treatment is performed on the welded pipe to eliminate the stress generated during the welding process and improve the mechanical properties of the pipe.
Cutting and trimming:
Cut the welded pipes into required lengths and trim the edges to ensure the pipes meet the required dimensions and appearance.
Surface treatment:
According to customer needs, the pipes are surface treated, such as hot-dip galvanizing, electro-galvanizing, spraying, pickling, etc. to improve corrosion resistance and aesthetics.
Inspection and testing:
Carry out quality inspection on finished products, including appearance inspection, dimension measurement, weld strength test, etc., to ensure that the products meet relevant standards and customer requirements.
Packaging and Shipping:
Pack qualified high frequency welded pipes and prepare to ship them to customers.
