Seamless Pipe Specifications for Different Shapes

Seamless pipe is a steel pipe made from steel ingots through multiple processes such as decarburization, impurity removal, preheating, perforation, three-round rolling, diameter reduction, cold drawing, annealing, etc. Compared with other steel pipes, seamless pipes have the advantages of higher dimensional accuracy, surface finish and strength, and are widely used in petroleum, chemical, aviation, machinery and other fields.

Specifications

The following are some common seamless pipe specifications of different shapes

1. Square pipe

Outer diameter: 10×10mm ~ 400×400mm

Wall thickness: 0.6mm ~ 20mm

Weight: 1.39kg/m ~ 74.55kg/m

2. Round pipe

Outer diameter: 6mm ~ 720mm

Wall thickness: 0.5mm ~ 120mm

Weight: 0.24kg/m ~ 120kg/m

3. Rectangular pipe

Outer diameter: 20×10mm ~ 400×300mm

Wall thickness: 0.6mm ~ 20mm

Weight: 1.43kg/m ~ 69.65kg/m

4. Oval pipe

Outer diameter: 25mm×15mm ~ 200mm×100mm

Wall thickness: 0.5mm ~ 12mm

Weight: 1.12kg/m ~ 28.58kg/m

It should be noted that different seamless pipe specifications need to be selected for different usage scenarios, such as large-diameter pressure pipes, thermal power station pipes, etc.

Application fields

Seamless pipes are widely used in petroleum, chemical, natural gas, nuclear power, aviation, aerospace, machinery, automobiles, heat exchangers, construction, high-pressure boilers, coolers, fertilizer equipment, cement industry, thermal power generation, medical equipment and other fields.

At the same time, with the continuous advancement of social science and technology, seamless pipes are gradually being used in the field of new energy, such as solar water heaters, wind power, solar photovoltaics and other fields.

Summary

In short, seamless pipes can be said to be one of the indispensable materials for industrial production, and their precision and quality play an important role in the production and development of related industries.
