HF ERW tube mill
HF ERW tube production line is mainly used for continuous production of straight welded pipe
- HF ERW tube mill
HF ERW tube production line is mainly used for continuous production of straight welded pipe, using high frequency induction or contact welding, not only can produce round pipe, but also can produce not more than the processing range of round pipe, square pipe and special-shaped pipe.
- Working principle
Steel tube of high frequency welding is using the skin effect of alternating current (AC) and adjacent effect, steel strip after rolling forming, the information of a cross section of broken circular tube billet, in the middle of tube billet inside near the induction coil rotating around one or a set of impedance, Impedance and tube billet was reluctant to form an electromagnetic induction loop, under the action of skin effect and the adjacent effect. A strong and concentrated thermal effect is produced at the edge of the opening of tube billet, which makes the edge of weld rapidly heated of the temp erature required of welding. After extrusion by the press roller, the metal in the molten state realizes indirect crystallization and forms a firm butt weld after cooling.

Cooperation Process
We engage in in-depth requirement communication with clients to understand their specific needs, project scope, requirements, and expectations. During this stage, we establish effective communication channels to ensure mutual understanding of the project.
Based on the client's needs and requirements, we provide customized solutions and product design proposals. Our technical team offers professional advice and solution designs to ensure feasibility and optimization of the proposed solutions.
After confirming the solution design and product specifications, we negotiate cooperation terms with clients, discussing key terms such as cooperation mode, pricing, and delivery time in detail. Once mutual agreement is reached, we sign the formal contract, outlining rights and obligations of both parties.
We commence production according to the contract and design requirements. Throughout the production process, we strictly adhere to quality management systems, conducting comprehensive quality control and supervision to ensure products meet client requirements and standards.
Upon completion of production, we package, transport, and deliver the products to clients on time. We provide user manuals and technical support to ensure clients can use the products correctly.
We commit to providing comprehensive after-sales service and maintenance support, including technical support, training services, and maintenance. We aim to establish long-term and stable cooperation with clients, offering continuous support and service to ensure long-term stable operation of the products.
We value client feedback and opinions, regularly communicating with clients to understand their user experience and changing needs.
