簡単な説明：

Welded steel pipe, also known as welded pipe, is a steel pipe made of steel coils or strip steel after crimping and welding, generally with a length of 6 or 12 meters. The production process of welded steel pipe is simple, the production efficiency is high, there are many varieties and welded steel pipe specifications, and the investment in equipment is small, but the general strength is lower than that of seamless steel pipe.

Welded Steel Pipe Advantages

The production process of straight seam welded pipe is simple, the production efficiency is high, the welded steel pipe cost is low, and the development is rapid. The strength of the spiral welded pipe is generally higher than that of the straight seam welded pipe, and the welded pipe with a larger diameter can be produced with a narrower billet, and different welded steel pipe dimensions can be produced with the same width billet. But compared with the straight seam pipe of the same length, the weld length is increased by 30~100%, and the production speed is lower.

Welded Steel Pipe Applications

Carbon welded steel pipes are widely used in water projects, petrochemical industry, chemical industry, electric power industry, agricultural irrigation, and urban construction.

液体の輸送、給水、排水に使用されます。ガス輸送用：ガス、蒸気、液化石油ガス。

構造目的: パイプや橋の杭として。埠頭、道路、建築物の配管など。

What Is Difference Between Seamless And Welded Pipe

The main difference between seamless and welded pipes lies in their manufacturing process and the structural integrity of the final product. Here are the key distinctions between seamless and welded pipes:

Manufacturing Process:

Seamless Pipes: Seamless steel tubes are manufactured through a process that involves piercing a solid billet or ingot to create a hollow tube. The tube is then elongated to the desired size using a mandrel mill or a rotary piercer. This process results in a seamless and uniform structure without any welding joints.

Welded Pipes: Welded pipes are manufactured by welding two or more pieces of steel together to form a tube. There are various welding methods used, such as electric resistance welding (ERW), submerged arc welding (SAW), and seamless pipe welding (SAWH). Welded pipes may have a longitudinal or spiral seam, depending on the manufacturing method.

Seam Presence:

Seamless Pipes: As the name suggests, seamless pipes do not have a welded seam. They are a continuous structure, which can provide better structural integrity and strength.

Welded Pipes: Welded pipes have a visible seam that runs along their length. The presence of a seam may affect the overall strength and integrity of the pipe, depending on the welding method used.

Strength and Performance:

Seamless Pipes: Seamless pipes are generally considered stronger and more reliable because they lack the weak points associated with welding. They are often preferred for applications where high pressure, high temperature, or corrosive environments are factors.

Welded Pipes: While welded pipes are suitable for many applications, they may have slightly lower strength compared to seamless pipes due to the presence of the welded seam. However, advancements in welding techniques have improved the performance of welded pipes in various scenarios.

Cost and Availability:

Seamless Pipes: The seamless pipe manufacturing process is often more complex and requires higher initial costs. As a result, seamless pipes are usually more expensive than welded pipes. Additionally, the availability of seamless pipes in larger sizes may be limited.

Welded Pipes: Welded pipes are generally more cost-effective and readily available, making them a common choice for less critical applications.
