Chemical pickling after production is standard at BUTTING. This guarantees pipes and components have optimum corrosion resistance. In addition, BUTTING offers mechanical surface treatments for pipes. Depending on the industrial application, we satisfy a wide range of requirements for outer surfaces and the weld seam area. Customer-specific requirements can be implemented by mechanical procedures, especially by grinding the outer surface.
External grinding is used mainly to meet optical requirements. BUTTING also has cylindrical grinding machines. We grind pipes in sizes from DN 15 to DN 300 and standard lengths from 4 m to 12 m. Here, particle sizes of 180 to 1 200 can be implemented, and optional fine grinding versions of Ra ? 0.5 microns are possible for special optical demands.
