Cold rolled seamless steel pipes are manufactured without any welded joints or seams. They are produced by piercing a solid billet of steel and then rolling it into a seamless tube. This seamless construction provides several advantages, such as improved strength, durability, and enhanced resistance to pressure and corrosion.

Cold rolled seamless steel pipes are available in a wide range of sizes, diameters, and wall thicknesses. This versatility makes them suitable for various applications, including oil and gas pipelines, machinery, automotive parts, construction, and structural components. The availability of different sizes allows for precise customization to meet specific project requirements.

The cold rolling process helps achieve a smooth, uniform surface finish on steel pipes. The absence of welds further contributes to the smoothness of both the interior and exterior surfaces. The smooth surface finish of cold-rolled seamless steel pipes reduces frictional resistance and facilitates the efficient flow of fluid or gas.

Cold rolling allows precise control over the dimensions of the seamless steel pipes. The manufacturing process ensures tight tolerances and consistent measurements throughout the length of the pipe. Cold-rolled seamless pipes have excellent dimensional accuracy, which is essential in applications where precise fit and alignment are required.

What Services Does Gnee Provide?

Gnee can provide the following measurement services for pipe:

1. Dimensional measurement: Measure the dimensional parameters such as length, width, and thickness by measuring instruments to ensure the pipe is qualified and meets the design requirements.
2. Surface measurement: Measure parameters such as flatness, unevenness, and surface roughness of pipe surface to help ensure that the quality and surface state of the pipe meet the requirements.
3. Thickness measurement: Use a thickness measuring instrument to accurately measure the thickness of the pipe to ensure that it meets the design requirements.
4. Material measurement: Use material analysis instruments to measure the chemical composition and mechanical properties of the product to ensure that the quality and performance meet the requirements.
5. Bending and Deformation Measurements: The degree of bending and deformation of the steel pipe is measured and monitored by using tools such as bending measuring instruments and displacement sensors to ensure that it is within the allowable range.

Ask Measurement service

Gnee can customize the size and shape of steel pipes for your project according to specific project needs. The custom design of the pipe is carried out by a professional engineer and design team. Based on the requirements and constraints of the project, they will use calculation and simulation tools, combined with experience and technical knowledge, to optimize the steel pipe design to meet the specific needs of your engineering.

● According to the strength requirements of structural design, adjust the thickness, width, and length of pipes.
