The production complex includes the steel plant, pipe rolling and smoothing of pipe. Such integrated structure allows to realize the company potential as much as possible. The main factory activity is connected with the production of steel jointless pipes of different sizes and diameters. Nowadays products of the factory are successfully used for the construction of pipelines by oil-and-gas, geological prospecting, machine building and industrial enterprises of Kazakhstan.

The rated capacity of the factory is 270,000 tones of steel jointless pipes per year. The steelmaking has the total productivity of 800,000 tones per year.
Let's move to the pipe rolling. The process of a pipe production is the following: a round cast workpiece is put onto a hot rolling line where it is cut, heated, stitched and rolled till a pipe of necessary size is ready.
This is a continuously cast round workpiece. Its diameter varies from 150 to 300 mm, length 5-12 meters. Steel jointless pipes are made exactly from these workpieces.
A hot rolling line is designed to transform cast workpieces into hollow ones with a certain diameter and thickness. At first a workpiece is placed in a carousel heat-treating furnace, where it is evenly heated to the temperature of 1280 °C.
