Line pipe coating to improve field joint bonds

anti-corrosion layer. The SureBond product line performs across a wide temperature range, from -70°C to 100°C, with low temperature bending and thermal cycling performance, a known limitation of three-layer systems. “SureBond opens up an important new category of line pipe coating,” said Cedric Oudinot, global product line manager at Bredero Shaw. “It offers significant benefits for operators – and it’s competitively priced, so they get a superior solution without having to pay more.” Bredero Shaw, a division of ShawCor, provides specialised coating systems and related services for corrosion protection, insulation and weight coating applications on land and marine pipelines, including highly engineered corrosion and insulation systems for deepwater applications.

Of the “special” products that it designs and makes, Galbiati has recently created an entire unit comprising a large-sized gear reducer for the facility at Marcegaglia, Boltiere, Italy, which specialises in the production of precision cold drawn tubes for the automobile sector and for hydraulic and mechanical applications. The gear reducer for drawing tubes designed for the customer, Marcegaglia SpA, inclusive of chain driving pinion and weighing a total of 63 tons, has an output rotation rate of 2 rpm and is powered by a 220kW electric motor. Main technical data: chain capacity 230 tons; primary diameter of chain driving pinion 740mm; motor power 220kW; and output rotation rate 2 rpm.

Since 1962, Galbiati Group has specialised in the design, production and revamping of large-sized components and finished products, gear reducers and speed multipliers for all those sectors that require advanced mechanical parts and/or machinery. The industrial applications vary from iron and steel to cement and grinding, and from energy to cableway. The Galbiati Group’s gear reducers for iron and steel applications are tailored to the customer’s specifications and are large with an extremely strong and sturdy structure. The power take off shafts often turn at a rate of less than 100 rpm and are powered by single or multiple electric motors even of several thousand kW. These turn the ladles of the cast iron-steel converters of the
