There are several types of thin-walled pipes according to production technology, including:
- The characteristics of a steel pipe are: ductility, dimensional accuracy, strength, weldability. Their use is suitable for lightweight structures, in which a large load is not provided. Subdivided into welded and seamless. Accordingly, the first type is suitable for structures where plasticity is required. Seamless can be used in situations where strength is a priority.
Steel pipes can be made by hot or cold deformation.
- Electrofusion.
Pipes, the seams of which are connected by electric welding, are produced in a rather convenient way and are reliable in operation. The brazing of the pipe edges guarantees resistance to stress and environmental influences. The raw material for electrowelded steel is most often alloyed or carbon steel in sheets. Also, as in seamless, cold-deformed and hot-deformed pipes are distinguished. Cold-deformed is applicable in the furniture industry, which is facilitated by its flexibility and quality, but the cost exceeds that of hot-deformed pipes. The production of furniture thin-walled pipes in Kharkov is significantly developed and supplies products to various companies in this industry.
With regard to profile pipes, it is common to manufacture square, rectangular pipes, as well as oval, hexagonal and other shapes.
Production of shaped pipes can be made of steel, aluminum and other alloys. The billet for profiling is most often a regular steel seamless pipe or welded. Such pipes are widely used in construction due to the stiffness of the ribs and strength. By heat treatment, the pipe takes on one shape or another, but each method has its own nuances.
