DuplexSpecial Focus Update
Duplex World Steering Committee meets once more
The new tube product represents the next generation of super-duplex seamless tubing developed specifically for the offshore oil and gas industry . It builds on the success of market-leading SAF™ 2507 ( UNS S32750 ), which has become the industry standard . Meanwhile , SAF™ 3006 is a high-alloy duplex stainless steel tailored to enhance corrosion resistance in acidic and caustic environments . The new alloy is an upgrade to traditional super-duplex stainless steels . The main application is heat exchangers in the chemical and petrochemical industries . SAF™ 3006 will be produced in Alleima ’ s fully integrated value chain , from R & D to end product , with tight quality control and a strong focus on sustainable production . The tube is based on more than 80 % recycled steel and melted and produced using a high degree of fossil-free energy sources . Seamless tube and pipe in SAF™ 3006 will be supplied in standard heat exchanger dimensions .
In March , the Steering Committee for the Duplex World Conference & Expo 2024 met to evaluate the abstracts submitted in response to the Call for Papers and to formulate the advance conference program . Headed by chairman Dr Yassar Ghanimi , Head of R & D services , Group Quality and Safety Management at Andritz AG , the committee comprises some of the world ’ s leading experts in duplex stainless steel . Members represent end-users , researchers , manufacturers , academics and suppliers . They arrived from thirteen countries to shape the technical conference program which features high-quality presentations , market insights , and a look at where the future of this versatile family of materials is heading . Duplex World will be held at the same time and location as the Heat Exchanger World Europe conference & expo , taking advantage of the great synergies between these two sectors . The events take place 13 & 14 November 2024 in Rotterdam , the Netherlands .
Stamicarbon secures urea contracts
Alleima unveils SAF™ 3007 for subsea umbilicals
Alleima has added two new duplex stainless steels . SAF™ 3007 is a super-duplex stainless steel grade developed for subsea umbilicals . The new tube offers a safe , lighter , stronger and more efficient alternative to SAF™ 2507 , the current standard . With superior strength , fatigue properties and excellent corrosion resistance , SAF™ 3007 delivers superior performance in harsh deepwater environments .
Jiangsu Huachang has awarded Stamicarbon licensing and equipment supply contracts for a urea melt plant in China . The plant , located in Jiangsu province , will have a capacity of 1860 MTPD and use Stamicarbon ’ s Ultra-Low Energy design with a highly efficient pool reactor concept . Stamicarbon will provide the license , proprietary equipment , including highpressure equipment made of super duplex stainless steel , and associated professional services . The main advantage of Stamicarbon ’ s Ultra-Low Energy Design is that the high-pressure steam is used three times instead of two , making the process more energy-efficient than the conventional CO2 stripping . This heat recovery scheme results in a 35 % reduction in steam consumption and a 16 % decrease in cooling water use .
