Century choice of low-pressure fluid pipe: straight seam VS seamless
First
Recently, many friends have thrown a crucial question at me: in the field of low-pressure fluid transportation, can straight-seam steel pipes be put into use instead of seamless steel pipes? This problem is self-evident for many projects involving pipeline engineering. Today, we will thoroughly analyze this question in an all-round and deep-seated way and give you a clear answer.
Starting from the core principle of engineering design, the answer given is categorical-no! There are extremely strict reasons behind this. When design engineers devote themselves to engineering design, they rely on a set of interlocking and strict technical standards system, and also cover the comprehensive consideration of pipeline performance in the whole service life. These technical standards and the provisions of the service period are just like the supreme "law" for engineering construction, and all the design and construction links must be strictly followed, and there is no room for carelessness. For example, in the construction of some large-scale industrial workshops, if pipes are randomly selected because of ignoring these standards, it is very likely that in the subsequent production and operation process, serious production accidents will be caused due to problems such as insufficient pressure-bearing capacity of pipelines, which will not only cause huge economic losses, but may even endanger people's lives.

However, the actual situation of the project is often complicated and changeable. If there is no clear and binding requirement on whether to choose seamless steel pipe or straight seam steel pipe in specific engineering projects, then there is some flexibility and room for discussion. We can make a comprehensive balance and detailed analysis from multiple dimensions according to the actual situation of the project site.
One of the remarkable features of seamless steel pipe is its relatively high cost. This is mainly because its production process is more complicated, which requires high production equipment and technical level. However, its advantage is also outstanding, that is, it has super durability. Seamless steel pipe has excellent compressive capacity and can withstand greater internal pressure steadily. Taking some high-pressure pipeline transportation in petrochemical industry as an example, seamless steel pipe has become the best choice to ensure safe transportation because the conveying medium often has the characteristics of high pressure, flammability and explosion. It can run stably in long-term high-pressure environment, greatly reducing the safety risks such as pipeline leakage.
On the other hand, the biggest advantage of straight-seam steel pipe is undoubtedly that the price is close to the people. This is undoubtedly very attractive to many projects with limited budgets. Moreover, with the development of the times and the continuous progress of technology, welding technology has undergone earth-shaking innovation in the past ten years, and now it has reached a quite mature level. On the premise of fully meeting the basic requirements of the project, choosing straight-seam steel pipe to undertake the task of low-pressure fluid transportation can save considerable cost for the project. For example, in some small municipal water supply and drainage projects, due to the relatively low demand for pipeline pressure, the straight-seam steel pipe can not only meet the engineering demand, but also greatly reduce the project cost and improve the economic benefits of the project by virtue of its price advantage.
Summary
Therefore, as long as the conditions of the project permit, it is a completely feasible choice to choose straight-seam steel pipe for low-pressure fluid transportation. But the crux of the problem lies in how to accurately judge whether the engineering conditions are allowed? This actually involves a series of more professional and in-depth knowledge fields. It covers the comprehensive analysis and consideration of the geographical environment of the project site, the characteristics of the conveying medium, the specific requirements of pipeline laying and other factors.
