In the field of petroleum pipelines, building structures and machinery manufacturing, ERW tubes and seamless steel tubes, the “metal twins” have always been a hot topic for engineers. These two seemingly similar tubes are fundamentally different in terms of manufacturing process, performance characteristics and application scenarios. In this article, we will unveil the mystery of […]

I. A molding process (1) Seamless steel pipe Seamless steel pipe is made by piercing the solid billet or ingot, and then processed by hot rolling, cold rolling or cold drawing and other processes. As the whole process does not produce welded seams, hence the name “seamless”. Hot rolled seamless steel pipe is one of

Seamless tubes for fluid transportation are the preferred solution for piping systems in the petrochemical, energy transportation and industrial manufacturing sectors thanks to their excellent performance. These tubes, which are made through advanced processes that eliminate the weakness of welded seams, are particularly suitable for transporting high-pressure, high-temperature or corrosive media. In this article, we

I. Product Characteristics Structural seamless steel pipe is a kind of steel widely used in construction, machinery manufacturing and other fields, with the following characteristics: A: high strength and high toughness: structural seamless steel pipe is usually made of carbon steel or low alloy steel, with high tensile strength and yield strength, able to withstand

I. General Purpose Seamless Steel Pipe Seamless steel tube is a kind of long steel with a hollow cross-section and no welded seam around. It is perforated from the whole round steel, widely used in the transportation of fluids (such as oil, natural gas, water, etc.) and the manufacture of structural components, mechanical parts. II.

I. Preparation of raw materials The production of seamless steel tubes begins with high-quality steel billets, usually made of carbon steel, alloy steel or stainless steel. These raw materials are subjected to stringent chemical composition analysis and visual quality checks to ensure that they meet the production requirements. The billets are also truncated and centered
