BUTTING – Pipes made from plate

If longitudinally welded stainless steel pipes are required in small quantities (often in non-standard sizes and in special alloys), in diameters of over NB 600 or wall thicknesses of more than 12 mm, then these are made discontinuously from plates in either 6 m or 12 m lengths. Depending on the requirements, also clad plates are used.

Pipes having wall thicknesses of up to 70 mm max. and outside diameters of up to 3,000 mm can be produced and welded with our modern production facilities. For 6 m lengths, the maximum ratio of OD/wall thickness is 1.2:10.

Besides common weld procedures, like TIG, Plasma-TIG, SAW, the very efficient Electron Beam welding is used by BUTTING as one of the few manufacturers in Europe.
