- Seamless tube rolling machine
Seamless tube rolling machine is including a plurality of rolls, rolls rolling pipe or outside of billet; core-rod shaped internal tool, which is arranged with the coaxial line of tube or tube billet; the deformation zone is defined between the roll and internal tool, which are suitable for perforating the tube billet and extension pipe in sequence.
- Process flow
Tube billet → Cutting → Heating → Piecing → Tube rolling → Sizing/Reducing → Straightening → Head and end cutting → Inspection → Packing → Storage
1. Piecing machine
Tube billet piecing is the most important deformation process in hot rolled seamless tube production, its task is to roll solid tube billet into hollow capillary tube, according to the structure of piecing and deformation characteristics of perforation process, can be divided into: cross rolling perforation, push rolling perforation and pressure perforation, and cross rolling perforation is the most widely used.
2. Tube rolling machine
Capillary rolling is the main deformation of hot-rolled seamless steel tube production process, its function is to make the tube thickness is close to or reached the wall thickness, finished product and the elimination of capillary in the perforation of longitudinal wall thickness is uneven, it also can improve the quality of tubes inside and outside of surface, control of waste pipe diameter and roundness, capillary rolled into close to finished size tubes. The pipe rolling mode is divided into automatic pipe rolling machine, continuous pipe rolling machine, (MPM two rolls continuous pipe rolling machine and PQF three rolls continuous pipe rolling machine), Assel roll rolling machine, Accu roll rolling machine and Pilger mill.
3. Sizing/Reducing machine
It is the last hot deformation process in the production of hot rolled seamless pipe. Its main function is to eliminate the discrepancy of outer diameter caused by the previous process of rolling. So as to improve the precision and roundness of outer diameter of hot rolled finished pipe. The process of tube sizing, reducing and tension reducing is the continuous rolling process without mandrel. At present, the domestic advanced sizing/reducing machine all use there roller 120° equal roller, using this form of sizing/reducing machine pipe surface quality is good, more specifications of finished pipe.
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.
