Product Details

Seamless stainless steel pipe is a tubular product made from stainless steel materials through precision processes, characterized by seamless connections.1It inherits excellent properties of stainless steel such as corrosion resistance, high temperature resistance, and high strength, and due to its seamless structure, it has higher pressure-bearing capacity and longer service life.1.

Features1

Corrosion resistance : Stainless steel seamless pipes can resist corrosion from weak corrosive media such as air, steam, and water, as well as chemical media like acids, bases, and salts.5.

High precision : Compared to welded steel pipes, seamless steel pipes have higher precision, smoother inner and outer surfaces, and uniform wall thickness.

Economy : The thicker the wall, the more economical and practical the stainless steel seamless pipe is; the thinner the wall, the higher the processing cost.8.

Applicability : Suitable for fields such as high pressure, high strength, and mechanical structural materials.4.

Manufacturing process : Typically manufactured through hot rolling, cold rolling, or cold drawing (rolling) methods.

Applications1

Seamless stainless steel pipes are widely used in various industries such as petroleum, chemical, pharmaceutical, food, machinery, and construction, making them an indispensable material in modern industry.1.

Specification representation3

The specifications of seamless stainless steel pipes are usually represented by the outer diameter and wall thickness in millimeters, for example, the outer diameter of a 304 stainless steel pipe.Wall thickness (for instance, if the outer diameter of a 304 stainless steel pipe is 100mm and the wall thickness is 2mm, the specification is represented as 100mm.2mm)3.

Precautions

During the manufacturing process of stainless steel seamless pipes, limitations such as uneven wall thickness, low brightness of inner and outer surfaces, and high cost of fixed dimensions are determined by the process.8.

Detection and shaping usually require offline processing.4.

The rust prevention mechanism of stainless steel is that alloy elements form a dense oxide film, isolating oxygen contact and preventing further oxidation.3.

Stainless steel seamless pipes may corrode in specific environments (such as environments containing chloride ions), so it is necessary to choose suitable stainless steel materials based on the usage environment.3.
