The characteristics of steel pipes include geometric and technical parameters. Geometric parameters include: thickness, length and diameter of the pipe wall. These parameters differ depending on the purpose of pipes and production features. In accordance with the features of production, seamless and welded steel pipes are distinguished. By purpose, steel pipes are divided into main and water and gas pipeline.
Its weight depends on the thickness of the pipe, and on weight, in turn, the cost. Distinguish between light, ordinary and reinforced steel pipes. In the diameter of the wall, steel pipes are divided into: pipes whose diameter is small (up to 114 mm), pipes with a diameter of medium size (from 114 to 480 mm), pipes, the diameter of which is large (from 480 to2500 mm and more).The length of steel seamless pipes is measured (from 4.5 to 9m), multiple measured (from 1.5 to 9m), Nemertia (from1.5 to11.5 m). The shape of steel pipes can also be different. The section can be rectangular, flat or other.
In order to operate steel pipes in industry, it is necessary to use all the characteristics when choosing from a wide assortment during the construction of metal structures.
