This is the third time that Schwarze-Robitec will be present at OSEA. Singapore is the ideal location for the trade fair, with the country seen as a hub for the Asian oil industry. Schwarze-Ro- bitec has been a reliable partner for oil and gas companies on the Asian market for many decades. The tube cold bending machines from the German company’s Heavy Duty series represent a power- ful solution for the fast, highly precise and efficient bending of

complex tube geometries. They enable users from the offshore industry to significantly increase production efficiency. The tube cold bending machines are spe- cially designed for continuous use under major strain. High-strength materials and very large, thick- and thin-walled tubes can be formed in various bending radii.
Complex tasks made simple
In terms of quality and support, Schwarze-Robitec is streets ahead of its competitors on the Asian
market. The company combines its decades of expertise and con- tinuous development to create bending solutions bearing the “made in Germany” hallmark.
The experts from Schwarze-Ro- bitec will be available at OSEA from 27 to 29 November 2018 at booth 1S3-08 to provide in-depth consulting in all matters related to tube bending in the oil and gas industry.
Strong, reliable booster bending machines for use in boiler and power plant construction
Schwarze-Robitec delivers ma- chines to Vietnam. Schwarze-Robitec has deliv- ered two of its booster bending machines for use in Vietnam’s boiler and power plant indus- tries. Martech Boiler Co., Ltd., an energy solutions provider, will now use a CNC 100 DB for the mandrel-free bending of thick- walled boiler tubes, and a FL 2000 for processing welded boiler walls. The machines, which are part of Schwarze-Robitec’s Boiler & Power series, are specially designed for the particular requirements of boiler and power plant construc- tion. They guarantee high-preci- sion bending performance and are designed for years of continuous operation.
Martech Boiler Co., Ltd., is a company based in Ho Chi Minh City, Vietnam, which specialises in the production of boilers and pressure vessels for the energy industry. Its portfolio of products includes waste heat boilers and boilers for fluidised bed combustion. For
years, Martech has been using a CNC 80 DB from Schwarze-Ro- bitec to bend tubes up to 88.9 mm in diameter. Impressed by the reliability and durability of the machine, Martech has again put its trust in Schwarze-Ro- bitec. Thanks to the new CNC 100 DB from the German company’s Boiler & Power series, Martech is now able to bend – without a mandrel – thick-walled tubes up to 114.3 mm in diameter at a wall thickness of 8 mm. One particu- lar stand-out feature is the com- pactly designed construction unit of the tube boost and integrated tube clamp element, which safely transfers the boost force to the tube. This enables, for instance, the mandrel-free cold bending of very small radii up to a radius of 1 x D with minimal reduction of wall thickness and optimum ovality. The Schwarze-Robitec method surpasses the tolerance speci- fications for wall thinning and ovality, for example, of the Euro- pean standard EN 12952 and the
American Society of Mechanical Engineers standard ASME B31.1 as well as all other international norms. This means that various media can be transported in the tubes in a consistently reliable manner.
Finned walls enable effective heat exchange
State-of-the-art power plant con- struction would not be possible without finned walls consisting of multiple tubes welded together, otherwise known as membrane tube walls. They ensure effec- tive heat exchange as part of a huge piping system. As part of this process, individual tubes are welded together to form bending membrane walls. They then undergo bending to align with boiler dimensions before being installed. To bend such finned walls, Martech uses the FL 2000 from Schwarze-Robitec. With mil- limetre precision, this machine processes entire bending mem- brane walls with a through-width of up to 2,000 mm in a single
