EN10219 Pre Galvanized Square Pipe Making Process
1. Uncoiling
Select galvanized steel coils that meet the EN10219 standard for quality and performance as raw materials, carefully inspect the surface smoothness, width, batch number, and other production records of the steel strip, and record them in a book for quality traceability. Place the galvanized coil on the uncoiling equipment for uncoiling.
2. Edge trimming and butt welding:
Cut off the irregular or unqualified edge parts of the galvanized strip head, trim the heads of the two rolls and perform butt welding. After welding, manually check whether the welding is firm.
3. Straightening:
The connected galvanized strip is sent to the straightening machine equipment for straightening
4. Roll cold forming:
Galvanized strip steel is fed into a continuous forming roll equipment for continuous rolling of the shape, forming a square section without welding. The weld seam of this square section is a straight line.
5. High frequency resistance welding:
Align the welding head with the straight weld seam of the square section for high-frequency resistance welding, and use the skin effect and proximity effect to firmly weld the flux and weld seam into a whole.
6. Remove welding bars:
The welded square tube needs to remove excess welding bars quickly while it is hot to ensure the beauty and uniformity of the welded pipe weld.
7. Calibration:
The welded square tube is subjected to secondary sizing to ensure that the size meets customer requirements.
8. Water cooling:
Use clean water to cool the welded square tube.
9. Cutting:
Cut the length according to customer requirements.
10. Inspection:
Manual inspection is carried out, such as appearance, straightness, and size. Unqualified pre galvanized square pipes are picked out, and Yuantaide Run will also pick out the joint pipes.
11. Spray label storage:
Spray label according to customer requirements, then package and store for shipment. Please note that Yuantai Derun has strict packaging standards. To learn more about specific packaging standards, please click here: Packaging Standards
