OFFSHORE - WIND POWER - ENERGY

 

Steel pipe construction, pipelines and ship building in the North and Baltic Seas present the highest demands on material and weld seams. For these extreme demands of the wind, energy, oil and ship building industries, we stock HF and UP longitudinal welded as well as seamless steel pipe from reputed manufacturers.

Pipe can be delivered from stock according to the following standards and materials:

  • EN 10225: Material S 355 G 13 + N/G 9/G10 + N/G 15 + N
  • API 5 L: Material Grade X 52N PSL2 modified
  • EN 10208-2: Material L 360 NB modified

 

WELDED STEEL PIPES

 

We stock and supply longitudinal and spirally welded steel pipes for many different areas of application and segments in standard or commercially available lengths according to your requirements.

EGYEDI MÉRETŰ CSŐGYÁRTÁS
Lehetőség van speciális, nem szabvány szerinti méretű csövek gyártására, ennek minimum mennyisége mindig a
gyártandó mérettől függ.
Gyártási lehetőségek préseléses technikával (hosszhegesztett cső): Ø 406,4- 2000 mm átmérőig, hossz: 2000-15100
mm, falvastagság: 8-101 mm
Gyártási lehetőségek hengereléses technológiával (hosszhegesztett cső) Ø 1000-4500 mm, hossz: 1000-3500 mm, falvastagság:
10-130 mm
Egyedi (mag) lyukasztásos technológiával készített honolt és honolásra alkalmas hidraulikus, varratnélküli és hegesztett
csövek 1600 mm átmérőig, 22 méteres hosszig különösen alkalmas energia, olaj és gáz, gépipari, vízgépészeti,
anyagmozgatási célokra.

 

The advantage of steel tubes for precision applications is the high precision of their manufacturing, the good quality of their surface, and the guaranteed mechanical and technological properties. That is why the pipes are widely used in the machining industry and in the automotive industry. Welded pipes for precision applications are manufactured in the process of cold drawing.
