materials. The industry has been using the traditional manufacturing method of casting billets, extrusion, pilger rolling and bench drawing reductions for many decades, but the latest manufacturing process is completely new. All produced materials comply strictly with the requirements of the ASTM, EN, GB and JIS standards. With all control systems in place, Golden Dragon will issue all required material certifications and on request initiate a third party inspection.

most demanding techniques, including new trenchless methods such as guided boring and horizontal directional drilling. These methods have a reduced impact on the environment, but they are more demanding of pipe properties, since surface damage during the installation process is more likely to occur. Apart from their good mechanical properties, 5924R and 5922R have unique rheological and morphological properties, created through a combination of proprietary catalysts and fine-tuned reactor and extrusion technology, that can provide processors with considerable energy savings. According to Jean Engels, business manager for HDPE at SABIC, processors will be able to make savings: “So, for example, a company already operating of these products in its home base of Xinxiang, in Henan Province, with a capacity to meet much of the world’s demands in these alloys. After continuously casting mother tubes, these are reduced with a patented system, after which they are reduced to final sizes on large spinner blocks. The produced coils are the basis for the final products, which will be level wound coils, pancake coils and straight lengths. Further newly developed and specially constructed equipment will reduce and finish the tubes to their final shape. An independent quality assurance control department continuously overviews the production and quality of all produced

SABIC’s latest Vestolen A Rely bimodal high density polyethylene grades are able to meet stringent requirements for typical pressure pipes, as well providing energy savings when producing the pipe. Two grades of SABIC ® Vestolen A Rely are currently available, both typically suitable for producing pressure pipe that meets the PE 100 standard. Vestolen A Rely 5924R delivers good low sag performance for large-diameter pipes and pressure pipes with a low standard dimension ratio (SDR). Vestolen A Rely 5922R helps customers meet the stringent slow crack growth requirements for pressure pipe, according to PAS (Publicly Accessible Standard) 1075. Certification to PAS 1075 enables the grade to be used for pipes intended for installation using the After a development period of many years, the China-based Golden Dragon Copper Corporation, a major producer of industrial copper tubes with several production units in Asia and America, has achieved a breakthrough in the production of copper alloyed condenser and heat exchanger tubes. The company has trusted Apeldoorn Metals International, also known as AMI-Dutchmetals, with the sale of these products in Europe and other areas of the world. Golden Dragon has developed and patented a cast and roll system for the production of copper nickel and aluminium brass condenser tubes, and has built a new factory for the production

a line at full capacity could be able to increase output by as much as 16% (compared with commonly used bimodal HDPE) while reducing electricity consumption. On the other hand, a pipe producer that does not need to raise production can realise energy savings by running at the same speed. Pipe size will also play a part in determining exactly how big the savings are.” Vestolen A Rely grades are currently available in black. For customers requir- ing fully coloured pipe, SABIC is working on the development of two coloured grades possessing enhanced resistance to slow crack growth propagation, to be commercially available in 2013.
