Classification of steel pipes

Rolled steel pipes are subdivided by technology of its production, by technological application, as well as by cross-sectional profile. Steel pipes are subdivided into

• - Seamless and electrically welded. The former are considered more robust and are subject to higher tensile strengths. Seamless pipe, depending on the method of rolling can be:
• - Hot- or cold-rolled, as well as pressed, obtained by hot extrusion from a solid bar.

Extrusion and rolling

During extrusion, the billet is run through a horizontal piercing hydraulic press, after which the final shape is given - it is calibrated and rolled. At the final stage of deformation, the steel tube is lowered into water, and then it is calibrated in a cold state. Rolled tubular products may be cooled immediately after extrusion, in which case the pre-calibration takes place in a cold state. Then the semi-finished material is heated to recrystallization temperatures, as a result of which internal tensions in the material are removed. Final rolling also takes place at normal temperatures. The standard diameter range for hot-rolled steel pipes is 20 to 550 mm and for cold-rolled steel pipes is 5 to 250 mm.

Electric-welded pipe

It can have a straight or spiral seam. First the parent billet - strip - is deformed along the future seam, and then either directly welded (straight seam), or pre-twisted (spiral seam). Evek GmbH offers to buy tubular rolled products at an affordable price in a wide range. Provide delivery of products anywhere in the continent. Price is optimal.

Profile pipe

Pipe of square and rectangular cross-section is most often produced. They are most common in the construction industry, in the production of frame elements of buildings and structures. Profile pipes can be made by two technologies:

• Bending into the desired profile on a horizontal bending press, with subsequent welding of the edges;
• Rolling from a tube of round cross-section.

Profile pipe is distinguished by its exceptional resistance to longitudinal bending. Their product range is in a wide range of values: from 10x10 mm to 450x350 mm.

Application

Round steel pipe is used for the installation of a variety of water and gas pipelines. Water and gas pipes are used in pressurized and non-pressurized water mains and gas pipelines of medium and high pressure. Such pipes are distinguished by increased stiffness, and therefore are able to withstand considerable bursting loads of the working medium pumped through them. The maximum specific force under which such pipes retain their integrity, up to 45 ... 50 ata.
