INTRODUCTION

Steel pipes are a necessity in almost every industry. They are integral to accelerating industrial work and making processes more efficient.

Among the many steel pipes, seamless pipes are one of the most sought after. Due to their mechanical properties, they offer better durability than welded pipes. Since they come from a solid metal billet, they are more resistant to stress and breaking. They are often required in high-precision and high-pressure applications.

Continue reading this blog to learn more about seamless pipes and how they are made.

Stainless steel seamless pipes are engineered for demanding applications that require high strength, leak-free performance, and resistance to extreme temperatures and pressure. These pipes are extensively used in onshore and offshore oil and gas operations, particularly for casing, tubing, and line pipe systems. They're also ideal for petrochemical transport, marine fluid systems, and high-load mechanical structures in power plants.

What is a seamless pipe

Seamless pipes are a steel pipe variant manufactured without any welded joints, hence its name. Their lack of seams reduces the risks of breakage under intense pressure and stress. Unlike welded pipes, they offer smoother surfaces and uniform diameters.

These properties allow them to have superior durability and corrosion resistance. All these remarkable characteristics make them ideal for the oil and gas industry and construction.

Development history of seamless pipe

The history of seamless pipes can be traced back to the end of the 19th century. With the advancement of industrialization, various manufacturing processes have gradually developed. In 1885, the Mannesmann brothers invented a machine. It drilled holes through rollers. This allowed steel to be made into pipes without welding. This invention led to better rolling processes in 1891. It marked a new stage in making seamless pipes.

In 1903, Ritteriefel of Switzerland invented the automatic pipe-rolling machine, which further improved production efficiency. With the advent of extension equipment, the modern seamless steel pipe industry took shape. This was due to continuous pipe rolling mills and pipe jacking machines.

In 1930, the introduction of three-roll mills, extruders and cold rolling mills promoted the advancement of seamless pipe manufacturing technology. By the mid-20th century, stress relief machines and continuous casting blanks improved efficiency. This made seamless pipes more competitive than welded ones.

By the 1970s, the sales of seamless and welded pipes were basically the same. Seamless pipes have no welds and resist high pressure. They are widely used in high-strength fields. Their demand grows over 5% a year. They are becoming a core product in the global steel pipe market.
