Seamless is used in many industries and in construction, and for the transportation of various liquid or gaseous media and to increase the rigidity of structures and buildings. The most common field of application is the installation of seamless pipes as basic units for water and gas supply mains, in which working environments are transported under pressure. Use in such cases of seamless pipes due to the fact that they, compared to welded, can withstand much larger pressures and sudden changes in temperature. They can be used in boiler plants. The greatest spread these products got in car production, shipbuilding, and the manufacture of cryogenic equipment. In other words, a seamless pipe is needed, where the strength calculations show that the use of welded pipes is impossible. Seamless pipe have high wear resistance and reliability even in the most intense and severe conditions.
