Bright ERW welded pipe vs. Ordinary welded pipe

Production process of bright ERW welded pipe and ordinary welded pipe:

Bright ERW welded pipe is a high-quality welded steel pipe, and the main production process is resistance welding or arc welding. During the welding process, the inner and outer surfaces of the pipe will undergo a series of cleaning and treatments, and the surface will be polished after high-temperature heating to make its inner and outer surfaces smoother and brighter. The ordinary welded pipe is produced by welding technology, and the production process is relatively simple, requiring pickling and annealing.

Characteristics of bright ERW welded pipe and ordinary welded pipe:

1. Different surface smoothness
Because the bright ERW welded pipe is polished, its surface is smoother, flatter and brighter, and it can achieve a high degree of cleanliness, while ordinary welded pipes do not have this feature.

2. Different processing performance
The processing performance of bright ERW welded pipe is better than that of ordinary welded pipe. Because of its high surface smoothness and easy welding, it can be processed more accurately and cut to size.

3. Different scope of use
Bright ERW welded pipes are mainly used in high-end decoration, precision machinery and other fields because of their beautiful appearance and good mechanical properties; while ordinary welded pipes are widely used in coastal areas, chemical industry, natural gas, refrigeration, machinery manufacturing, construction and other fields.

Prices of bright ERW welded pipes and ordinary welded pipes:

The price of bright ERW welded pipes is relatively high because its production process is relatively complex and the product quality is more stable and accurate. The production cost of welded pipes is low and the price is relatively low.

Precautions for purchasing bright ERW welded pipes:

When purchasing bright ERW welded pipes, pay attention to the following points:

1. Determine the specifications such as pipe diameter, thickness and length;
2. Understand the material, surface treatment, production process and other information of the product to ensure that it meets the use requirements;
3. Before purchasing, check the product information, certification certificates and other relevant materials;
4. Purchase products from regular channels to avoid buying counterfeit and inferior products.

Conclusion:

Bright ERW welded pipes and ordinary welded pipes are both common steel pipe products, which differ in their production processes and product characteristics. The choice of product should be based on its specific usage scenarios and requirements.
