The durability of straight seam welded pipes and spiral welded pipes is a relatively complex issue, as their durability is influenced by various factors, including usage environment, material, welding process, maintenance, etc. The following is a detailed analysis of the durability of both:

1. Usage environment

Under the same usage environment, such as similar conditions such as temperature, pressure, and medium, spiral welded pipes, due to the structure of their spiral welds, can withstand liquid pressure distributed on all sides of the pipe, thereby enhancing its strength. Therefore, in situations where it is subjected to greater pressure or stress, spiral welded pipes may exhibit higher durability.

However, in specific corrosive environments, such as acidic environments, the corrosion rate of spiral welded pipes may accelerate, and their lifespan may be correspondingly shortened. In contrast, the performance of straight seam welded pipes may be more stable in corrosive environments.

2. Material and Welding Process

The durability of straight seam welded pipes is greatly affected by the material and welding process. High quality steel and good welding processes can improve the durability of straight seam welded pipes.

Spiral welded pipes also rely on high-quality steel and exquisite welding techniques. Due to the longer length of the weld seam in spiral welded pipes, higher technical proficiency and quality control are required during the welding process to ensure the strength and durability of the weld seam.

3. Maintenance and upkeep

Reasonable maintenance and upkeep can extend the service life of both straight seam welded pipes and spiral welded pipes. This includes regular inspections, cleaning, anti-corrosion treatment, etc.

For spiral welded pipes, due to the special structure of their welds, more frequent maintenance and inspection may be required to ensure the integrity and strength of the welds.

4. Service life

The shelf life of straight seam welded pipes can usually reach more than five years, but the specific lifespan depends on the usage environment and maintenance situation. If subjected to significant impact or pressure during use, its lifespan may be shortened.

The service life of spiral welded pipes is generally over 10 years, and if used in a good environment and installed and maintained properly, the service life can reach over 20 years. But it is also affected by the usage environment and maintenance situation.

In summary, the durability of straight seam welded pipes and spiral welded pipes cannot be simply generalized. They may exhibit different durability characteristics under different usage environments and conditions. When choosing, it is necessary to comprehensively consider the specific application scenarios and requirements, while also paying attention to the impact of factors such as materials, welding processes, and maintenance on durability.

The price difference between straight seam welded pipes and spiral welded pipes is influenced by various factors, including raw material costs, production processes, market demand, etc. The following is an analysis of the price difference between the two:

1. Raw material cost

Both use steel as their main raw material, but fluctuations in steel prices can affect production costs, which in turn affect the final selling price. In terms of raw material costs, if steel prices do not fluctuate significantly, the difference in raw material costs between the two may not be significant.

2. Production process

The production process of straight seam welded pipes is relatively simple and has high production efficiency, so the production cost may be relatively low.

The production process of spiral welded pipe is relatively complex, including multiple links such as coiling, forming, welding, etc., and requires higher technical level and quality control, so the production cost may be relatively high.

3. Market demand and supply

Market demand and supply conditions can also affect the prices of both. If the market demand for a certain type of welded pipe exceeds the supply, the price may rise; On the contrary, if supply exceeds demand, prices may decrease.

4. Specific price comparison

In the actual market, the prices of straight seam welded pipes and spiral welded pipes may vary depending on specific specifications, quality grades, purchase quantities, and other factors. For example, in some cases, the price of straight seam welded pipes may be lower than that of spiral welded pipes; In other cases, the prices of the two may be similar or the price of straight seam welded pipes may be higher.

5. Price Trends and Purchase Suggestions

Due to the constantly changing market supply and demand, raw material costs, and other factors, the prices of straight seam welded pipes and spiral welded pipes may also fluctuate. Therefore, it is recommended to closely monitor market dynamics and price trends when making purchases.

When choosing welded pipes, in addition to considering price factors, it is also necessary to comprehensively consider various factors such as usage environment, material, welding process, maintenance, etc., to ensure the selection of the most cost-effective product.

In summary, the price difference between straight seam welded pipes and spiral welded pipes is influenced by various factors and cannot be simply generalized. When making a purchase, it is recommended to consider and choose based on specific needs and budget comprehensively.
