Product Description Factory Supply Spiral Welded Pipe MillBack-swing spiral welded mill introduction: 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. The uncoiling, coil detaching, leveling, steel cutting and welding are working on the fly-welding carriage. When the steel is welded, the fly welding carriage moves forward in the same speed with the host equipments. The host machine will not have the stop. After the steel welding finishing, fly welding carriage backs forward to the original position t owait another coil. This mode is called continuous production method with high efficiency, high pipe quality, rare welding repair and other advantages.According to the different function of our products, the back swing spiral welded pipe mills are divides in to API standard model and national standard model. API standard 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. National 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 steel also are very high, second only to that of API standard.Summary The welded pipe mill is back swing continuous production spiral welded pipe mill with a flying welding car, a rear axle swing, and a steel plate edge positioning. This mill is our company's most advanced model, with the following new and patented technology: Forming machine automatic adjustment systemThis machine adopts the database + computer automatic control technology to adjust the machine when it changes the specification. According to the steel pipe specification range that the unit can produce, a complete database has been established. In the production of steel pipe of a certain specification, only the parameters such as plate width, pipe diameter and wall thickness need to be input on the computer, and all the adjustment parts will reach the correct position by themselves and start production directly. This reduces the need for adjustment, the reliance on experienced tuners, and the waste pipe. Due to the complexity of the equipment, the database data may not be completely suitable, so the system design has fine-tuning function and database correction function. After a certain specification is adjusted properly, the database can be modified and can be directly produced when it is re-produced.Joint clearance automatic control systemThe spiral welding unit is affected by factors such as camber and stress release during the production process, and the joint gap will change, which will affect the forming and welding. If the joint gap is small, the wrong side will be generated. If the joint gap is large, the weld penetration will occur and the welding will not be performed normally. The usual method is that after the worker sees the wrong side or the welding wear condition, the hydraulic swinging rear axle adjusts the joint gap by the jog button to achieve the purpose of stable welding. The adjustment of the manual adjustment is uncontrollable and is adjusted by experience, which will result in an increase in waste pipe. The welding seam gap automatic control system can measure the gap of the welding seam in real time by laser measuring the joint gap. According to the measured value and the theoretical value ratio 0.1-0.2mm), the system will automatically adjust the rear axle digitally when the theoretical value is exceeded. Control the joint gap to achieve stable welding and stabilize the pipe diameter.Intelligent quality file management system in steel pipe logistics processThis system is the intelligent quality management and steel pipe filing system in the process of steel pipe logistics developed by our company, which can make the steel pipe quality management intelligent, systematic and Instamatic. And can automatically generate every shift, every day, every month, every year of production statistics, convenient management to understand the overall operation of the unit.Steel pipe length after cutting, the system will assign a unique steel pipe coding for the tubing, and the coding spraying on the tube body, steel will use this encoding and subsequent finishing area of each equipment to communicate, and the steel tube in the finishing area by the craft route, the various process conditions, inspection, repair, repair again check all gather together into a tube quality files, this steel braided like id card, just enter the weave, the identity of all information will be presented, Including production date, production team, coil manufacturers, steel coil furnace number, material, diameter, wall thickness, welding speed, welding wire material, whether to have joint repair welding, X-ray, ultrasound, flat head chamfering, hydraulic pressure, pressing time, pressure curve, whether the defect repair welding and repair welding the re-inspection after all of the information, and so on. This file is stored in the system like the id card of the steel pipe. It can also be backed up in electronic form and delivered to the customer together with the steel pipe. This system is especially suitable for the production of high-grade steel pipes for oil and gas transportation and other purposes, because each steel pipe of high-grade steel pipe needs to be traceable. If there is a problem, the reason can be found, and the most reasonable solution can be designed for the cause of the defect.The system has established an identity card for each steel pipe, which can be easily traced back to the source, and the establishment of the steel pipe file is established by the system itself. There is no human factor, and the file has higher credibility. The system can also make the production management intelligent. The system will calculate the specifications, quantity, yield, number of defective tubes and defects of the steel tubes produced in this shift. When the shift is off work, a report will be automatically generated to show the production situation and quality. The management can also formulate measures based on the cause of the defect to improve the yield. Of course, the monthly total statistical table will be automatically generated every month to facilitate the high-level understanding of the overall operation of the unit.Pre-uncoiling designBecause the demolition work of thick-walled high-strength steel coils takes a long time, often causing downtime waiting and affecting production efficiency, the unit revolutionized the design of the pre-uncoiler. The pre-uncoiler can disassemble the head of the next coil during the normal production of the unit and lead a distance. When the unit coil production ends, the truck will directly transport the steel coil that has been taken out of the head to the unwinding. At the machine, the opened head is inserted into the pinch roller of the pinch leveler. After the taper head is inserted into the inner diameter of the coil, the steel strip can be directly transported forward. This greatly saves the time for the head to be removed, and the efficiency of the unit production is greatly improved.Uncoiler automatic centering functionThere is the centering button on the operation stand of uncoiler. When the button is switched on, the double cone heads will automatically centralize the mill centerline. Then, the coil center is consistent to the mill center. It is no need to adjust with the vertical rollers. The production efficiency is improved and the instability is decreased. In addition, the unit also has the uncoiler plate tail bending device to avoid the difficulty of passing the tail; the cutting and butt welding at the butt joint separate structure, truly realizes the bevel function of the butt-welded steel plate.The main objectives of the unit: product physical quality, production costs, various consumption indicators and labor productivity have reached the domestic advanced level.The unit equipment is a complete spiral welded pipe equipment integrating mechanical, electrical automation control and hydraulic control.The unit is designed and manufactured with safety protection devices for equipment and safety protection for operators. To protect the operational safety of important equipment and the safety of operators. For example, a pressure limit protection sensor is provided in the pressing mechanism of the leveling machine; the pressing mechanism of the delivery machine also has a self-protection function when the plate thickness suddenly changes.Since the whole control system uses the bus technology, the equipment operating parameters are digitized, combined with the various levels of power protection devices and various sensor components set on the hardware, through the management of the system software, the various operating parameters can be transmitted to the control in real time. The center analyzes and processes the operating status of the control equipment in time, and can display these parameters on the HMI synchronously for the operator to perform timely and effective operation, so that the operability and safety of the whole unit are qualitative. improve.The unit uses edge positioning.List of machineNo.NameQty1Pre-uncoiler12Detaching & Leveller13Uncoiler14Pinching & Leveler15Cutting & Burr Welding Machine16Submerged arc Welding Car17Vertical Roller on Fly-Welding Car18Pinching Device19Fly-welding Car & Rail Supporting Roller110Vertical Roller On The Ground111Precision Leveler112Rough Edge Miller113Precision Edge Miller114Steel Sheet Surface cleaner115Delivering Machine116Pre-bending &Guide Board117Forming Machine118Internal & External Welding Device119Lincoln Welder420Laser weld automatic tracking system121Welding flux supply and recovery system122Welding Flux handling device123Rear Axle& Centralizer Device124Fly Cutting Machine125Carried Pipe Car 26Anchor bolts and embedded parts in main machine 27Hydraulic System in main machine 28Electrical control machine in main machine Total (Main Machine Area) 29Vacuum type internal welding slag removal device 30Inside and outside welding seam grinding machine 31Pipe End Expanding Machine 32X Ray Inspection Device 333000T Hydrotester 34Φ3600 Pipe End Facing & Chamfering 35Φ1626 Tube End Flaring Machine 36UT Tester 37Pipe End X Ray filming 38Weighting, Measuring Marking device 39Carried Pipe Car 40Pipe Conveying Roll Bed 41Rotating Roller 42Pulling Pipe Device 43Receiving Pipe Device 44Rack 45Active Pulling Pipe Device 46Fixed Pulling Pipe Device 47Anchor bolts and embedded parts in Precision Area 48Hydraulic System in Precision Area 49Electrical control machine in Precision Area If you need detailed offer about the spiral welded pipe mill, please provide your reuqirments.Diameter: φ000mm-φ0000mmLength: xmm-xx mm
