Main Technological Characteristics Of Spiral Steel Pipe

a. During the forming process, the steel plate is deformed uniformly, the residual stress is small, and the surface is not scratched. The processed spiral steel pipe has greater flexibility in the range of diameters and wall thicknesses, especially in the production of high-steel grade thick-walled pipes, especially small and medium-diameter thick-walled pipes. It has advantages that are unmatched by other processes and can satisfy users. More requirements in terms of spiral steel tube specifications.

b. Using advanced double-sided submerged arc welding process, welding can be achieved in the best position, it is not easy to appear defects such as wrong edges, welding deviation, and under-welding, and it is easy to control the welding quality.

c. Carry out 100% quality inspection on the steel pipe, so that the entire process of steel pipe production is under effective detection and monitoring, which effectively guarantees the product quality.

d. All the equipment of the entire production line has the function of networking with the computer data collection system, realizing the real-time data transmission, and the technical parameters in the production process are controlled by the central control room. 

1. The principal requirement of spiral steel tube stacking is to palletize according to varieties and specifications under the premise of stable palletizing and ensuring safety. Different types of materials should be palletized separately to prevent muddy and mutual erosion;

2. It is forbidden to store items that have an erosive effect on steel around the spiral steel pipe stacking station;

3. The bottom of the spiral steel pipe stack should be high, strong and flat to prevent the material from being damp or deformed;

4. The same kind of materials are stacked separately according to the storage order;

5. Spiral steel tubes stacked in the open air must have wooden pads or stones underneath, the stacking surface is slightly inclined to facilitate drainage, and pay attention to the placement of the materials straight to prevent bending deformation;

6. The height of spiral steel pipe stacking, manual work should not exceed 1.2m, mechanical work should not exceed 1.5m, and stack width should not exceed 2.5m;

7. There should be a certain channel between the stacks, the inspection channel is generally 0.5m, and the access channel depends on the size of the material and the transportation machinery, generally 1.5 ~ 2.0m;

8. Angles and channel steels should be stacked in the open air, that is, with the mouth facing down, the I-beam should be placed upright, and the I-slot surface of the steel should not be facing upwards, so as to prevent rust from accumulating;

9. The bottom of the stack is high. If the warehouse is a sunny concrete floor, the height should be 0.1m; if it is mud, the height should be 0.2~0.5m. If it is an open field, the height of the cement floor is 0.3-0.5m, and the height of the sand surface is 0.5-0.7m. Quality inspection editing Spiral steel tubes should be tested for mechanical properties, flattening and flaring before they leave the factory, and must meet the requirements of the standard.
