Basic configuration:Only includes the main body of the spiral welded pipe unit. The customer needs to configure or outsource the subsequent flat head chamfering, hydrostatic testing, and non-destructive testing equipment. This applies to manufacturers with limited budgets or existing rear equipment.Conventional/Mainstream Configuration:Spiral welded pipe unit+fully automatic flat head chamfering machine. This is a common "package" because welded pipes must be cut and chamfered to become transportable and usable single pipes. Hydrostatic testing and non-destructive testing may be outsourced or purchased.Complete production line configuration:Spiral welded pipe unit+fully automatic flat head chamfering machine+fully automatic steel pipe hydrostatic testing machine+ultrasonic flaw detection system (usually online or offline)+X-ray detection equipment.This is a configuration for customers in the mid to high end market who have high requirements for product quality and automation, such as the production of oil and gas pipelines, structural pipelines, etc. Equipment suppliers typically offer turnkey projects for the entire production line. If you are looking for customized solutions for spiral welded pipe units, please feel free to contact us and we will tailor a customized solution for you!

There are significant differences in appearance between direct insertion high-frequency straight seam steel pipes and submerged arc straight seam steel pipes, mainly reflected in appearance and fastening joints.From the appearance, the high-frequency steel pipe body is flat and wavy, without any composite skin adhesion.From the weld seam, the high-frequency straight steel pipe weld seam is an irregular saw shaped weld seam, with two types: extruded and serrated. Before leaving the factory, such welds are scraped off and need to be cleaned thoroughly.There are slight strip-shaped indentations on the appearance of submerged arc welded steel pipes, mainly distributed inside the pipes. The straight seam steel pipes buried in the arc welding fastening seam are arranged neatly, which is superior to the 1-3mm weld seam of the underlying metal.Before the completion of the factory, the fastening joints will be "polished" and removed according to customer requirements, leaving traces of grinding wheel polishing.

Recently, Dorco Heavy Industries successfully delivered a customized aluminum ring rolling machine to a client as scheduled.

The numerical control system has many highlights:Use electronic handwheel for operation.It can achieve multifunctional and multi station rolling.Input the dimensions of the ring and blank, and automatically generate the rolling curve.Easy to operate, only one electronic handwheel is needed to complete the entire rolling process.The dual screen displays the working status, and the new console has a wide field of view.Automatic CAR operation mode, the rolling process automatically matches the radial and axial rolling according to the rolling curve.

The automation configuration is as follows:1. Use a slide table with a single axis robot to grab the bars from the heating furnace and send them to the upsetting station of the press;2. Use a flat four axis robot to transfer workpieces at three workstations of the press;3. Single axis robots equipped with ejector devices and transition tables are used to unload and wait for materials at the three workstations of the press;4. Adopting a dual robot mobile platform for automatic loading and unloading of the ring rolling machine;5. Use KUKA210 robot for loading, unloading, and palletizing of ring components;6. Automation auxiliary equipment: waste conveying installation;7. Mold cooling and cleaning device;8. Raw material cooling conveyor line;9. Stacking pallets, etc.The system includes functions such as on-site monitoring, real-time production indicators, and equipment efficiency analysis. Through a visual dashboard, the on-site status can be easily and clearly understood.

The main difference between the assembly of high-frequency straight seam steel pipes and buried arc straight seam steel pipes is the use of different raw materials, forming methods, fastening methods, production units, and production processes. Submerged arc straight seam steel pipes are produced using the narrowest 1250mm coil, medium plate, and medium thick plate as production materials. High frequency straight seam steel pipes are produced from the widest 1500mm strip steel. Low content of strip steel. The forming method of buried arc straight seam steel pipe is JCOE cold stamping, which is characterized by gradually forming sheet metal in units of 50mm. J. C, O, and E represent the forming method of buried arc straight seam steel pipes.The forming method of high-frequency straight seam steel pipe can be a cold forming process using multiple rollers, which compresses and aligns the two ends of the strip steel. Its characteristic is that the molding method is uninterrupted and continuously fastened. The characteristic of the submerged arc fastening method is to use the electric shock along the wire and plate to fasten the filler. The characteristic of the fastening method for high-frequency straight seam steel pipes is to use the high-frequency electrical phenomenon of electric current to generate a temperature rise in the cross-section of the strip at both ends in a short period of time and cause the strip to self melt under external force. The high-frequency straight seam steel pipe production unit is on the same impact line as the uninterrupted production line, while the submerged arc fastening straight seam steel pipe has up to fifteen intermittent production processes. High frequency straight seam steel pipes have fewer specifications and thinner thickness. The buried arc straight seam steel pipe can produce any specification of 325-1600mm or more, with a thickness of up to 80mm.

In terms of implementing conventions, both forms of steel pipes follow the same execution standards: GB/T3091-2208,GB/T9711.1-2011,GB/T9711.1-2001,API 5L PSL1,API 5L PSL2； However, the certification certificates for these two forms of steel pipes are completely different. The high-frequency steel pipe certificate uses "ERW", and the submerged arc welded steel pipe certificate uses "ASWL".
