Our plant specializes in the production of circulation water pipelines, which are essential components of cooling systems at energy facilities such as thermal power plants, nuclear power plants, and hydroelectric power plants. We offer comprehensive solutions for the efficient supply and discharge of cooling water, ensuring high reliability and longevity of our products. The pipelines are manufactured using modern technologies and are reinforced with channel bar ribs, which guarantee their resistance to loads and long service life. The plant pays special attention to quality at every stage of production, allowing us to deliver products that meet the strict standards of the industry.

Steps of pipe manufacturing from a steel sheet (RU)

Manufacturing steps

Serpukhov Pipe Plant is equipped with high-tech European equipment, enabling the production of reliable and wear-resistant products. The pipes manufactured by the enterprise are of high quality and precisely meet the specified dimensions, fully meeting the needs of customers.

Step #1

Cutting of Steel Sheet

The sheet is placed on a plasma cutting machine, where metal is cut to the size of the future pipe.

Step 1. Cutting the steel sheet

Step #2

Preparing the Sheet for Welding

Operators use special equipment to clean the edges and ends of the sheet for the future welding seam.

Step 2. Preparing the sheet for welding

Step #3

Shaping the Sheet into a Cylindrical Form

The prepared sheet is sent to Italian rolling mills, where it acquires the necessary rounded shape.

Step 3. Shaping the sheet into a cylindrical shape

Step #4

Welding of the "Root Seam"

The obtained cylinder is placed on a semi-automatic welding machine. Here, operators weld the "root seam," securing the walls of the pipe.

Step 4. Root seam welding

Step #5

Welding of the Internal and External Seams

The pipe is sent to a welding complex produced in Sweden, where automatic welding of the internal and external seams under flux is carried out.

Step 5. Internal seam welding

Internal seam welding

Step 5. Outer seam welding

Step #6

Calibration of the Finished Pipe

The pipe is sent to rollers for calibration to give it a perfectly round shape.

Step 6. Calibration of the pipe
