High-quality spool prefabrication and shaped parts
FINOW Rohrsysteme has a long tradition as steel-processing company since being the very first pipeline construction company founded in Germany. Today company incorporates state-of-the-art know-how for manufacturing of high pressure piping systems and experience with the market and technology of the whole world.
For more than a century, we have been providing individual sustainable solutions for a wide range of applications - in the construction of nuclear and thermal power plants, in the chemical sector, the oil and gas industry.
Our products are used in the creation of energy-efficient and ecological projects: from green pipelines to the offshore wind sector.
Induction bending on our two bending machines lies at the heart of high-pressure spool prefabrication. FINOW uses these to produce pipe bends that often have better material properties than those of the original straight pipe. This means that pipe material of the same wall thickness can be used for both bends and straight sections.
FINOW processes all standard material grades in high-pressure piping construction up to an outer diameter of 1,220 mm or wall thickness of 120 mm. Our high-pressure prefabrication capacity totals approx. 4,500 t of piping spools per year.

Thermal power stations
Pipelines for the oil&gas industry

Induction bending
The central part of HP spool prefabrication is induction bending on our bending machines—Cojafex-PB-Special and Cojafex 1200 R—to bend pipes without molds, ring beams, or inner cones.​​

Cutting
A CNC plasma cutting plant covers the entire range of pipe-cutting tasks such as pipe lengths, weld edge preparation, nozzle cutouts, and saddle curves, which are often performed in a single machining operation. Finow has five different pipe-cutting systems in total at its fabrication facility.​​

Non-destructive and destructive testing (an in-house laboratory)
Work zones get checked for changes in wall thickness and inner defects using ultrasonic testing. Surfaces get checked for cracks using dye penetration or magnetic particle testing. Non-destructive material testing is available on request

Cold bending
Cold bent elbows from Finow are shaped parts to be welded. We manufacture them as elbows with long sides using seamless pipes. Their shape offers advantages compared to the well-known weld-in elbows. Also, we deliver elbows with specific dimensions for maintenance and repair purposes.

Heat treatment
We manufacture our products using high-grade materials according to technical standards. Further heat treatments such as normalization can be carried out on request. To ensure that the material features are optimal, we have two program-controlled car bottom annealing furnaces heated by natural gas and with various dimensions and temperatures.

Welding
Our core expertise is induction bending and welding piping elements. Finow is approved as an expert welding company in line with DIN 18 800 by SLV Berlin-Brandenburg.​​​​​
