Renowned customers such as Statoil, ConocoPhillips, Shell, BP, ExxonMobil and Chevron use our products.We are the only pipe manufacturer in the world that produces both longitudinally welded metallurgically clad and mechanically lined pipes.BUTTING also processes clad pipes into ready-to-install spools.Clad pipesYour contact personBrigitte BlechingerSales Oil & Gas Upstream Phone: +49 5834 50-230brigitte.blechinger@butting.de4Metallurgically clad pipesMetallurgically clad pipes offer the advantage of smaller wall thicknesses compared to austenitic solid-wall pipes and solid-wall pipes made from nickel-based alloys. Other benefits include considerable weight savings and reduced material costs.Metallurgically clad pipes are used, for example, as SCR, riser or process pipes, pipelines or pipes for elbows and fittings. Other application areas can be provided on request.BUTTING has been producing longitudinally welded metallurgically clad pipes in varying material combinations since the 1980s. Sizes range from OD 114.3 mm (4“) to OD 1 219 mm (48“), and wall thicknesses of up to 70 mm are achievable. The maximum wall thickness / outer diameter ratio is 1:10. The manufacturing lengths without circumferential weld are 6 m or 12 m. Using a circumferential weld, lengths of 18 m or 24 m can be achieved. We have already produced approx. 15 000 t of metallurgically clad pipes for projects worldwideOur facilities enable the production of up to 6 km of metallurgically clad pipes every monthCLAD PIPES5CLAD PIPESClad plates are used as raw material for the production of metallurgically clad pipes. The plates consist of a base material and a corrosion resistant alloy material. They are linked together fi rmly by a diffusion bridge.The plates are formed individually on a press brake, using the JCO process, into an open seam pipe and provided with a longitudinal weld by a number of different welding processes.We can also provide heat treatment for the clad pipes after the welding process, depending on the intended use.Within quality assurance, various non-destructive tests can be carried out on the fi nished pipe: dye-penetrant, magnetic particle, ultrasonic, X-ray, dimensions test and a test of the residual magnetism can be carried out.The production processBUTTING produces metallurgically clad pipes, mainly from roll-bonded plates; it is also possible to use explosion clad raw material. Cladding can be attached on one side, internally or externally, or on both sides (splash zone).© voestalpine6 CLAD PIPESThe benefit in cost-effectiveness terms of BuBi® pipes rises as the total piping system increases7CLAD PIPESMechanically lined BuBi® pipes The mechanically lined BuBi® pipe (BUTTING Bi-metal pipe) was launched by BUTTING as a market innovation in the mid-1990s.Compared to a corresponding solid-wall version, the use of BuBi® pipes can save 25 – 40 % of costs. Due to the manufacturing process and the raw material used, it is economically superior to the metallurgically clad pipe. Another advantage is the wide range of materials that can be selected for both inner and outer pipe. Highly variable combinations of the relevant materials are possible.The start of a success story: BuBi® pipes ready for shipment for the West Libya Gas ProjectBuBi rail express: For the Tyrihans Project of our customer Statoil, more than 500 wagons had to be loaded8 CLAD PIPESMechanically lined BuBi® pipesFor many years, BuBi® pipes have been used success-fully in the onshore and offshore areas of the oil and gas industry. Typical applications are pipelines or riser pipes; they are also installed as SCR pipes. Other areas of use are available on request.Up to now, BUTTING has produced more than 650 km of mechanically lined BuBi® pipes for a variety of projects. Our manufacturing facilities enable the production of up to 18 km of BuBi® pipes per month.© Statoil9CLAD PIPESIn the hydroforming process we developed, a corrosion resistant pipe is lined into a pipe of high strength carbon-manganese steel and expanded with the help of a hydroforming press. The hydraulic expansion process offers the advantage of uniform pressure distribution without damaging the pipe surface.In further processing, the BuBi® pipes are provided with a seal weld or a weld overlay at the pipe ends, to prevent moisture ingress.Sizes range from OD 114.3 mm (4“) to OD 660 mm (26“). Other sizes, even outside the standard, can be produced by agreement. We manufacture lengths of up to 12.2 m, any lengths beyond this up to 24 m are achieved through circumferential welding.The BuBi® pipe is suitable for various laying methods.Production process 0 12 3Main steps of the expansion processThe inner pipe and the outer pipe are expanded together by water pressure. Because of the normally more elastic resilience of the outer pipe, the inner pipe is placed under residual compressive stress. A secure mechanical tight fit is produced.10 CLAD PIPESUse as riser pipesIn the oil and gas industry, clad pipes are used, inter alia, as riser pipes.The riser pipes developed for use in deep-sea areas are especially exposed to dynamic stresses and high temperatures. They must not be susceptible to fatigue, must have excellent mechanical properties and a high degree of strength and corrosion resistance. When producing these pipes, it is therefore necessary to comply with the strictest tolerances and special quality standards.BUTTING is the market leader in this area. We achieve the strictest inner diameter tolerances of +/- 0.25 mm. Thus the displacement of the pipe-ends is minimal, the welding on the construction site is improved and the working life of the pipes increases.The tolerances are agreed according to current standards, e.g. API, ASTM, DNV or ISO, and even stricter tolerance requirements have already been implemented for a number of BUTTING projects.A milestone: for the major project Guará & Lula, BuBi® pipes are used for the first time in the world as riser pipes; we deliver a total of more than 84 km of BuBi® pipes and metallurgically clad pipes for the order from Brazil11CLAD PIPESBUTTING processes clad pipes into spools ready to install. For this we use semi-finished clad material such as welded flanges, elbows, tees and reducers.Prefabrication of clad pipes is used to optimise the pipeline quality and to reduce costs. At an early stage in the production plant, the corrosion resistant layer of the piping components is pickled and passivated and all the non-destructive tests are performed.This leads to considerable potential savings, especially during the subsequent installation of piping systems at the construction site.Ready-to-install clad spoolsThe direct additional processing of our pipe allows us to optimise the quality of the piping, and to supply you with products ready for laying at value-for-money prices BUTTING offers prefabrication of metallurgically clad spools at the highest quality level03 · 2012CLAD PIPESSpezialrohre und angearbeitete RohreKorrosionsbeständige Rohre und FittingsSpezialrohre und angearbeitete RohrePlattierte RohreEinbaufertige Komponenten und RohrleitungenBehälter, Tanks und KolonnenIpis volupiet, commos dolo ut ides dolorpo rereruntBUTTING GroupGifhorner Straße 5929379 KnesebeckGermany www.butting.com
