General IntroductionASME,ASTM Standards International EquivalentProminent Supplier of 9% Nickel Steel in ChinaThe 9% nickel steelis a low-carbon nickel alloy steel with nominal composition of 9Ni,which is particularly used for low-temperature or cryogenic pressure vessels and plants for processing,transportation,and storage of LNG down to -196°C [-320°F].The steel is originated from International Nickel Companys lab in 1940s.It has relatively higher strength and allowable stress than austenitic stainless steels,aluminum and steel.The 9% nickel steel exhibits excellent fracture toughness even at cryogenic temperatures.See more on metalspipingDevelopment of 9% Nickel Steel for LNG Applications - Kern Dec 13,2016·This article presents the development of 9%nickelalloyed highstrength steels for low temperature applications and gives an overview on their production,properties,and processing behaviour.Heavy plates of these steels meet the highest demands on strength,toughness and resistance against brittle fracture. results for this questionHow is stainless steel used in the LNG industry?How is stainless steel used in the LNG industry?Stainless steels for cryogenic applications down to liquid helium temperatures are well established and play an important role in LNG ships and in piping systems and associated equipment.Reference www-off-axis.fnal.gov/flare/technical_papers/welding_tanks.pdf results for this questionWhere is LNG stored?Where is LNG stored?The LNG is stored in the 9% nickel steel inner tank.The steel liner installed on the inside surface of the outer concrete tank provides the gas tightness.The boil-off rate is determined by the insulation system.In case of an LNG leakage, liquid may impact on the outer tank.DEVELOPMENT OF THE WORLDS LARGEST ABOVE results for this questionWhat kind of welding is needed for a LNG tank?What kind of welding is needed for a LNG tank?Some real test results from WPQR for an LNG Tank in 9% nickel steel are given in Table 5.The magnetic properties of 9% nickel steel mean that arc blow will be encountered when welding.AC welding is therefore often preferred with OK 92.55,but DC may also be used.Welding liquid natural gas tanks and vessels in 5% and 9% nickel steels
Figure 3 shows an aboveground,flat-bottomed,cylindrical LNG storage tank known as a PCLNG.This structure,widely adopted in overseas countries,has a surrounding wall made of pre-stressed concrete (PC),an outer shell and roof made of low temperature service carbon steel,an inner shell made of 9% Ni steel,and an inner aluminum deck that is suspended from the carbon steel dome roof on the (PDF) Electrodes for Welding 9% Nickel SteelThe use of cryogenic 9% nickel steels for building storage tanks for liquified natural gas (LNG) is discussed.LNG storage tanks consist of a cryogenic steel inner shell and a concrete outer shell.662 .767 - Nippon Steel CorporationNippon Steel has developed 9%Ni thick steel plates for large LNG storage tanks by applying not only intercritical heat treatment but also decrease of Si content and small addition of Mo.The commercially produced 50mm thick plate exhibits suffi-cient mechanical properties for LNG storage
Jun 19,2014·NSSMCs 7% Ni steel will be the first new steel sheet standard for LNG storage tanks in about a half century.The order for Soma LNG storage tank will be the third one,following an order received for the Senboku-I No.5 tank (Osaka Gas) in 2012 and an order received for the Chita Midorihama tank (Toho Gas) in 2013.CHALLENGES,PROPERTIES,AND FEATURES OF 9%9%Ni steel plate is the material of choice for the construction of Liquefied Natural Gas (LNG) storage tanks at export and receiving terminals all around the world.Fully ductile at -196°C,well below the boiling point of liquid methane,the traditional 9%Ni steel grade ASTM A553 type I or EN 10028-4 X7Ni9 also combines high strength andCited by 10Publish Year 2012Author Yong-Keun Yoon,Jae-Hoon Kim,Kyu-Taek Shim,Young-Kyun KimDEVELOPMENT OF LOW-NICKEL STEEL FOR LNGDEVELOPMENT OF LOW-NICKEL STEEL FOR LNG STORAGE TANKS Hitoshi Furuya Tomoya Kawabata Yasunori Takahashi Nine-percent nickel steel,which was developed by the International Nickel Company (INCO) in 1946 ,has [20,21]),nickel content was at 7.1%.The steel plates manufactured at Nagoya Works (notated as steel B ),nickel
A 9% nickel heavy plate for large LNG tanks was developed by applying intercritical quenching,an effective heat treatment method for improving the toughness of nickel-bearing steel.DEVELOPMENT OF MATERIALS OF CONSTRUCTION FORto highlight the potential for use in new LNG projects.INTRODUCTION .9% Nickel steel plate is the most common material used to construct the cryogenic containment system of tank bottom plates to the 60mm of some storage spheres pieces .The achieved yield to tensile ratio of 9% Nickel steel is about 90% and over,and does not give rise to Development of 7%Ni-TMCP Steel Plate for LNG StorageThe inner tank material for above ground LNG storage tanks have mostly been made of a 9% nickel steel plate over the last 50 years as it has excellent mechanical properties under the
ASTM A 645 Gr B achieves material properties equivalent to those of traditional 9% nickel steels in LNG storage but meets these requirements with roughly 30% lower nickel content.A further result is substantially reduced costs in the production of onshore and offshore LNG tanks and in the construction of LNG fuel tanks.How to Weld 9% Nickel Steel for cryogenic tanksA larger application of 9% nickel steel is for large LNG field storage tanks and for containment vessels on LNG tankers.Welding practices for field construction may be similar to shop procedures,although fabricators often develop proprietary welding procedures for certain welds.Including results for nickel steel plates 9 percent for lng storage.Do you want results only for nickel steel plates 9 percent for lng sorage?9% Nickel Steel for LNG and Cryogenic Applications·UK Steel distributor Masteel supplies 9% Nickel steel to both commonly used specifications ASTM A353,which comes in plate thicknesses up to 100mm,and ASTM A553 Type 1,which is generally limited to a plate thickness of 50mm.13 This high purity 9% Nickel steel is ideal for applications in the storage and production of LNG,oxygen,nitrogen and other cryogenic applications.

The spherical tanks for the Moss-Rosenberg type of liquefied natural gas (LNG) carriers are to be fabricated from rolled and forged nine percent nickel (9Ni) steels,with the former steel being used as tank shell-plate material and the latter as tank equator-ring material.Welding LNG tanks and vessels in 5% and 9% nickel steelsweld metals closely matches the 9% nickel steel itself.Some real test results from WPQR for an LNG Tank in 9% nickel steel are given in Table 5.The magnetic properties of 9% nickel steels make that arc blow might be en-countered during welding.AC welding will reduce the magnetic the recommended current type to use.Welding liquid natural gas tanks and vessels in 5% andmetals closely matches the 9% nickel steel itself.Some real test results from WPQR for an LNG Tank in 9% nickel steel are given in Table 5.The magnetic properties of 9% nickel steel mean that arc blow will be encountered when welding.AC welding is therefore often preferred with OK 92.55,but DC may also be used.OK 92.45 is only used with DC.
·In order to obtain less conservative design values,the results of high manganese steel and various nickel steels were compared to those of BS7910.As a result,the CTOD value of high manganese steel is higher than that of 9% nickel steel at cryogenic temperature.
