Clad pipes

Requirements

Impressively consistent

BUTTING uses clad materials when it comes to pipes with a maximum load-bearing capacity. Project-specific, material combinations in line with the requirementsfor every area of application guarantee high internal corrosion resistance and high external pressure resistance, along with cost savings of up to 40 % compared to solid-wall pipes.

Leading through experience

BUTTING is the global market leader for clad pipes. These are the first choice in industry when high dynamic loads, high pressures and a high aggressiveness of the transported media prevail. Companies worldwide rely on quality from BUTTING.

We have been processing clad materials into pipes and piping components for almost 40 years. As the global market leader for clad pipes, we manufacture mechanically lined BuBi® pipes (4" to 26"), glued mechanically bonded GluBi® pipes (6" to 18") and metallurgically clad pipes (4" to 48") at our site in Knesebeck. But we can also take on your individual challenge: together with you, we develop solutions for component parts.

Mechanically lined vs. metallurgically clad

In case of mechanically lined pipes, a longitudinally welded stainless steel inner pipe is inserted into an outer pipe made of carbon-manganese steel using mechanical processes. The advantages of mechanically lined pipes:

  • Cost savings of up to 40 % compared to solid-wall pipes
  • High internal corrosion resistance with high external pressure resistance
  • Project-specific, material combinations in line with the requirements

Metallurgically clad pipes are manufactured from appropriate plates in which the metal layers are metallurgically bonded by a diffusion bridge. The advantages of metallurgically clad pipes are:

  • Reduction in wall thickness
  • Cost benefits even with small dimensions compared to solid-wall pipes
  • Weight saving
  • Wide range of material combinations

Metallurgically clad pipe

As regards BUTTING pipes made from metallurgically clad plates, the metal layers are firmly bonded by a diffusion bridge. As a result, they combine high strength and special surface properties. They are suitable as SCR, riser, process or line pipes for laying in the S-lay, J-lay, bundle or reeling method.

Technical details at a glance:

  • Dimensional range OD 114.3 (4") to 1 219 mm (48")
  • Wall thicknesses up to 70 mm
  • Maximum wall thickness / outer diameter ratio 1:10
  • Production lengths of up to 24 m (6 m or 12 m lengths without circumferential weld)
  • Suitable for S-Lay, J-Lay, bundle or reeling installation methods

Clad spools

Optimise your piping system by using spools ready for installation from BUTTING. The combination of our clad pipes with weld-clad semi-finished products such as flanges, bends, T-pieces or reducers ensures consistently optimum quality and is particularly economical thanks to easier installation at the assembly site.

Advantages of clad spools ready for installation:

  • Use of high-quality semi-finished products from BUTTING production
  • High degree of automation and high reproducibility
  • First-class processing quality, e.g. thanks to consistent quality assurance
  • Savings due to less welds and assembly times on the construction site

Mechanically lined pipes

BUTTING bi-metal pipe (BuBi® pipe)

In the early 1990s, BUTTING developed the mechanically lined BUTTING-bi-metalpipe - BuBi® pipe for short. In this process, a corrosion-resistant BUTTING stainless steel pipe is inserted into a carbon-manganese steel pipe followed by mechanical bonding using a hydroforming system.

Technical details at a glance:


  • Dimensional range OD 114.3 (4") to 660 mm (26")
  • Production lengths up to 24 m (up to 12 m without circumferential weld)
  • Manufac tured in accordance with API, ASTM, DNV or ISO
  • Suitable for S-lay, J-lay, bundle or reeling installation methods
