Production resources of the SARYARKA plant include 3 modern pipe production lines and a line for steel rolls cutting.

Produced products that meet the requirements of DIN EN 10219 are in high demand in the countries of the Customs Union and the European Union.

The well-established logistics of delivery of raw materials ensures the possibility of rapid fulfillment of urgent orders.

The process of manufacturing of electrically welded hollow sections and pipes begins with the supply of rolled sheet steel to the production department along its own railway line.

Rail cars are used for transportation, and the process of unloading raw materials is organized through special crane mechanisms. Rolls of steel fall on the sites of preliminary control, where the quality service checks the external condition of the rolls, the presence of marking, compares the actual parameters with the accompanying documents of the supplier.

Then the raw material is sent to the slitting line: the roll is unwound and cut into strips of the required width. The cutting speed reaches 100 meters per minute. The cut strips are stored in a dry warehouse.

At the next stage, rolled steel strips are moved to pipe lines and installed on a decoiler, and from there they move to a horizontal storage device. The ends of the strips are successively welded together by the "butt-end" argon-arc welding method, which ensures uninterrupted feeding of strips into the tube stand. Special molding rollers of different calibers gradually bend the edges of the metal, giving the steel bands a pipe shape. Longitudinal welding is carried out by high frequency currents, this method allows to achieve the highest quality of the welded joint and to accelerate the welding process up to 75 meters per minute.

After the formation of the welded seam and removal of the burr, the pipe is cooled in a special bath with an anti-corrosion coolant, and the calibration rollers give it a specified profile (round, square or rectangular) with precise geometric dimensions.

The resulting welded seam is tested by the non-destructive method of eddy current testing by means of a special flaw detector.

A flying saw cuts the pipe to the required length at a speed of up to 150 meters per minute. The finished pipe falls on a roller conveyor, where it is sorted and packed into packs for transportation.

Each bundle of pipes is tied with steel ribbons, marked and supplied with a special identification code that contains information about the batch, the date of receipt, the certificate number, the steel grade, the work shift and the production date, and also indicates the weight of the bundle gross and net, the size and length of the packed pipes.

After that, the products are loaded on trucks and sent to the covered warehouse of finished products.
