SAF™ 3007 for subsea umbilicals
SAF™ 3007 ( UNS S83072 ) is the latest addition to Alleima ’ s growing duplex family , a super-duplex stainless steel grade especially developed for subsea umbilicals . The new tube offers a safe , lighter , stronger and more efficient alternative to SAF™ 2507 , the current industry standard . To date , Alleima has delivered more than 160 million meters to all major fabricators and applications worldwide , equivalent to circling the globe three times . Due to its refined chemical composition , SAF™ 3007 not only cuts overall costs , but provides a lighter tube that streamlines the entire umbilical manufacturing process , making the statement of “ Less is More ” both true and relevant .
particularly in LNG . Alleima expects the LNG industry will be a serious game changer for Sanicro™ 35 as it is increasingly recognised as a longlasting , economical material for a wide range of equipment in corrosive environments . Barinder explains : “ The LNG sector has been a particular focus for Alleima for the past seven years , particularly FSRUs ( Floating Ship Regasification Units ). In the past , the LNG vaporisers in FSRUs experienced many corrosion issues . Our R & D team looked into the problems and found that we had existing grades which provided satisfactory solutions . Then in 2021 , we released Sanicro™ 35 , a superaustenitic stainless steel alloy which is easy to work with and bridges the gap between stainless steel and costly nickel alloys . It has proven to be ideal for FSRUs and we recently booked some nice orders for that application .” “ The grade is quickly gaining popularity because it bridges the gap between austenitic and high nickel alloys ,” continues Barinder . “ It ’ s much more economical to use than high nickel alloys yet offers the same long lifecycle and quality .” “ We are focusing on providing the full range of products needed to supply complete packages of Sanicro™ 35 , including pipes , tubes , flat products , fittings and forgings . We ’ ve learned from the past that providing complete packages will give customers the confidence to specify it widely .” “ We anticipate that Sanicro™ 35 will become the new workhorse for many industries ,” adds Jane . “ It ’ s a much more cost-efficient material with a lower nickel content and a correspondingly
smaller CO2 footprint . As it ’ s ideal for so many industries and applications , customers will save money because they won ’ t need to have multiple grades in stock ; they will only need this one alloy .” Barinder continues : “ It will also be a game changer for the hydraulic and instrumentation sector , which until now has used many different material grades . Sanicro™ 35 will provide significant savings as it replaces expensive alternatives such as Alloy 625 .” In a costconscious environment , Sanicro™ 35 can be considered an all-round tube solution to many H & I and HX challenges .
Heat exchanger express hollows program While heat exchanger tubes may only be a small part of a large and complex refinery , an unexpected failure can force a shutdown and a significant loss of income . To alleviate this problem for customers , Alleima recently launched its express hollows program to ensure it could offer rapid solutions to customers who urgently need stock . “ Delivery time to customers in Europe , the Middle East and Africa ( EMEA ) has been reduced to just eight weeks from order to placement ,” explains Jane . “ A supply of material hollows is maintained to be shipped with a very short lead time . The program also provides flexibility to rapidly send small quantities for emergency maintenance . The express hollow program has been a great success because it means customers can restart their equipment earlier and minimise production losses .”
