Seamless pipes (BS) are needed where strength and reliability are required. Pipes of this type are used in the oil industry, mechanical engineering, aviation.
Seamless pipes are made according to a special rental technology, which allows pipes without spiral or longitudinal seams that do not prevent fluid or gas passage.
Seamless pipes are hot -rolled (hot -formed) and cold -rolled (cold -deformed).
Hot -rolled pipes are made by rolling in hot condition. The material in hot state is subjected to minor mechanical deformations.
Cold -deformed pipes without a seam after rolling in a hot state are subjected to additional rolling in a cold state. This method allows you to make a product with greater accuracy, so cold -rolled seamless pipes are used in areas where the quality and accuracy of the material is important.
