Butting Duplex and Superduplex Pipes 

Since stainless steels were first developed, the production of high-quality longitudinally welded pipes has been the focal point of the business. 

When longitudinally welded stainless steel pipes are required, even in small numbers or in special sizes or materials, BUTTING manufactures them from steel plate. BUTTING has enlarged its stocks of the necessary pre-materials, to guarantee that they can satisfy individual pipe requirements with short delivery times at a high level of quality. 

As well as the standard materials, 1.4541 and 1.4571, the store also includes steel plates of TP 304L and TP 316L in Knesebeck. To cover your urgent requirements, the family owned company can produce pipes with wall thicknesses from 6.35 mm to 12.7 mm.  In addition, they have specialised in storing steel plate in duplex or superduplex. BUTTING can within a very short time manufacture duplex pipes (UNS 31803 or UNS 32205) for you in wall thicknesses from 4.78 to 22.7 mm. 

Superduplex steel plates (UNS S32760) in wall thicknesses from 4.78 mm to 12.7 mm are in store for the quickest possible delivery in sizes specific to your project. These newly stored steel plates mean that the store now comprises around 300 t.

In this area of production BUTTING uses not only the traditional TIG, Plasma-TIG and submerged arc welding technologies, they are also one of the few manufacturers in Europe to use the effective electron beam welding technology. 

BUTTING places great emphasis on the excellent quality of the products we supply: To ensure the best possible surface condition, only top quality pre-materials are used and the pipes are all supplied pickled and passivated.
