Seamless Steel Pipe

Seamless steel pipe is a steel pipe manufactured without welds. It is a product that is formed by heating a billet to a certain temperature and then forming the billet into a tubular shape by drawing or piercing.

Information such as dimensions, lengths, and pressure ratings of seamless steel pipes vary by application and standard specification.

Size:

The outer diameter (OD) and wall thickness (WT) of the seamless steel pipe are its main size parameters. Dimensions are usually given in inches (inch) or millimeters (mm).
Common seamless steel pipe outer diameters range from small to large and can be from 1/8 inch (3.175 mm) to over 36 inches (914.4 mm). The wall thickness also varies according to different needs, ranging from thin-walled pipes to thick-walled pipes.

Length:

The length of the seamless steel pipe is also determined according to the demand. Generally, the length of the seamless steel pipe is between 6 meters and 12 meters, but according to the project requirements, longer or shorter pipes can be produced.

Pressure rating:

The pressure rating of seamless steel pipe depends on the material, size and application scenario of the pipe. Common pressure rating standards include ANSI/ASME (American National Standards Institute/American Society of Mechanical Engineers), DIN (German Institute for Standardization), EN (European Standards), etc.

The pressure rating is generally represented by standard PN, Class or pressure rating, such as PN16, Class 150, 3000 psi, etc.

Material:

Seamless steel pipes can be manufactured using a variety of steel materials, such as carbon steel, stainless steel, alloy steel, etc. Different materials are suitable for different working environments and requirements.

It should be noted that the above parameters are only common ranges, and the specific dimensions, lengths and pressure levels may vary due to standards, manufacturing processes and customer needs. When selecting seamless steel pipe, it should be selected according to specific project requirements and specifications to ensure that the pipe can meet the required performance and safety requirements.

Features and Benefits:

1. Seamless structure: The seamless steel pipe is processed through one-time processing without welds, so it has higher strength and pressure resistance. The weld seam is one of the weak points in general steel pipes, prone to cracks and corrosion.
2. Superior mechanical properties: Since the seamless steel pipe avoids welding defects during the manufacturing process, it has a more uniform structure and higher mechanical properties, and can withstand higher pressure and temperature.
3. Wide range of uses: Seamless steel pipes are widely used in many fields, including oil and gas industry, chemical industry, nuclear industry, aerospace, automobile manufacturing, etc. Due to its high strength and reliability, seamless steel pipes are often used in occasions that need to withstand high pressure and high temperature.
4. Smooth internal and external surfaces: Since seamless steel pipes are manufactured by stretching or perforating processes, their internal and external surfaces are relatively smooth, which reduces fluid resistance and facilitates the flow of liquids and gases.
5. Wide range of sizes: Seamless steel pipes can be manufactured in various sizes and thicknesses according to different needs, so as to adapt to the use in different fields.
6. Corrosion resistance: Seamless steel pipe can enhance its corrosion resistance and prolong its service life through different surface treatments and coatings.

In a word, seamless steel pipes have been widely concerned and used because of their superior mechanical properties, smooth inner and outer surfaces, and a wide range of application fields. In industrial production and infrastructure construction, seamless steel pipes play an important role.
