Product Description Front Swing Spiral Welded Pipe Mill The steel coils are unfolded and leveled by the mill equipment. And they are sent to the forming machine in a certain angle. Supplemented by a certain angle, the continual pipes are formed in the principle of three-roll rolling machine. Continual spiral welding is welded by submerged-arc welding machine. When the uncoiling, coil detaching, leveling, steel cutting and welding are working, the host machine needs to stop and wait. After the steel welding finishing, the host machine starts to work again. The front-swing spiral welded pipe mill adopts intermittent production method with advantages such as low investment, and simple convenient. According to the different function of our products, the front swing spiral welded pipe mills are divides in to API model and standard model. API model mainly produces the delivery pipe with petroleum or natural gas (long distance). The material and quality of the steel pipe need to be very good. The requirements for mill equipment and testing equipment also are very high. The standard model produces the pipe used for short distance delivery of natural gas or water, the pipeline construction in the city, the structure pipe, column pipe and so on. The requirements for the material and quality of the coil also are very high.This mill is our company's most advanced model, with the following new technology.A. Forming Machine Automatic Adjustment SystemThe adjustment of the molding machine adopts database and computer automatic control technology. When changing specifications, it is necessary to adjust the front axle angle, the six-component roller angle, the six-group roller position, and the welding pad roller angle. The previous adjustment work was done by experienced workers, basically relying on workers' experience. In this way, it is easy to adjust improperly, resulting in more waste pipes, and a relatively large workload, which is very cumbersome. The angle and position of the front axle of the unit and the forming machine to be adjusted are controlled by the encoder. And according to the theoretical data in advance, a complete database has been established. When producing a certain specification of steel pipe, you only need to input parameters such as width, pipe diameter, and thickness on the computer, and all parts will reach the correct position by themselves and start production directly. This reduces adjustment work, reduces dependence on workers, and reduces waste steel pipes.B. Uncoiler Automatic CenteringThe uncoiler console of this unit is equipped with an "alignment" button. When this button is pressed, the double column head of the uncoiler will automatically align with the center line. In this way, the edge of the steel plate going in will be consistent with the center line of the unit, without adjusting the vertical roll. Improve production efficiency and reduce instability in the production process.Production Process:Loading Coil - Uncoiling - Leveling - Cutting and Coil Welding - Edge Milling Machine - Feeding Machine - Pre-bending and Guide Board - Forming Machine-Internal Welding - External Welding - Tracking and Cutting Off - Pipe Pulling Out - Welding Seam Grinding - Pipe End Expander - X-Ray Inspection - Hydraulic Testing - Pipe End Facing and Beveling - Ultrasonic Inspection - Pipe End Take Photo - Weighting, Measuring, Marking - Finished Product CollectionPre-Sales Services1) Answer the customers' questions about investment consulting on the field of tube machine.2) According to the production process requirements, plant management requirements and the company development, offering proposals and plant layout drawing for the customers.3) Customers can visit the tube production line in our factory for free.After-Sales Service1) Provide the relevant shipping charge information, take charge of loading and the relevant shipping procedure, focus on the safety of the goods and the shipping time.2) Provide the technical documents about machinery installation, maintenance, operation and so on.3) Provide the technical support about the machinery installation, maintenance, operation and so on.4) Provide the equipment list of the main components.5) Responsible for the equipment installation and commissioning guidance.6) Provide one year warranty.7) Provide post-paid warranty service after shelf life.
