Natural gas represents a significant part of total world energyconsumption, driven by both economic & ecological advantages.The reserves of natural gas are generally remote from the pointsof consumption, leading to major investments in transportationand storage.

Natural gas cooled to -162°C at atmospheric pressurecondenses to a liquid known as liquid natural gas or LNG.LNG is an efficient route for transportation and storage as theliquid gas occupies ~1/600th the volume of natural gas.

Material selection for LNG large storage tanksMaterial dedicated for storage & transportation of natural gasat cryogenic temperatures should have high ductility andresistance to cracking.

For economic reasons, a high strength steel grade is required inorder to reduce the section thicknesses and hence the weightof steel sections when building cryogenic storage tanks.

9%nickel steel is selected, in place of stainless steels, due tothe combination of high strength and reliable fracture toughnessat -196 °C. Due to the combination of a low carbon content andlow levels of impurity elements with a process route includingheat treatment cycles such as quenching or normalising followedby a tempering treatment, 9%Ni steel retains reliable mechanicalproperties at cryogenic temperatures.

9%Ni steel specifications and a summary of mechanicalproperties are shown below:

There are several types and designs of onshore tanks for thestorage of LNG, designed for single, double or full containmentin case of fire, or an in-ground system may be used, selected asappropriate for the surroundings of the tank. These LNG tanksare large structures, typically approximately 80 m diameter and40 m in height containing ~150,000 m3 of LNG, comprising aninner 9%Ni tank contained within an outer structural steel vapourbarrier, with an insulated cavity in between, within theslip-formed concrete tank. Design studies arein progress to confirm the possibilities oflarger onshore cryogenic tanks witha useable capacity of up to300,000 m3 of LNG.

During fabrication of an onshoreLNG tank, the dome roof isfabricated inside the structure andon completion is raised to the top.The plate thicknesses of the tankvary to accommodate thehydrostatic loading from the liquidgas, tapering from typically 27 mmat the bottom to 10 mm at the topof the tank.

9%Ni steels are easily and strongly magnetised, consequentlyarc blow caused by residual magnetism is a consideration. OERLIKON welding consumables for fabricating 9%Ni steelsare designed for operation on alternating current with all powersource technologies.

The fabrication sequence is to weld the horizontal seams in thePC position using the submerged arc process with AC polarity,simultaneously from both sides, with either OERLIKON OP 76/NIFIL 625 or OP F77/ NIFIL C276. The vertical and overheadseams, PE and PG positions respectively, are welded using themanual metal arc process with OERLIKON FREEZAL ENi9 withAC polarity. In these section thicknesses a low pre-heat only of+10 ºC may be required as there are large quantities ofaustenite in the plate microstructure and therefore thesusceptibility to hydrogen, cold, cracking is inherently low.The maximum interpass temperature used is generally 150 ºC.These applications are further illustrated with the typical weldingprocedures shown on pp 7 to 9.

Internally, below the dome roof is an insulated aluminium deckfabricated in alloy 5083, welded using the MIG and TIGprocesses with grade 5183 consumables. 5083 series wroughtaluminium alloys contain Mg as the major alloying element and

are used in LNG storage tanks for theconstruction of walkways, due to the

combination of weight andmechanical properties.

During fabrication using the MIG and TIG processes, attentionshould be given to shielding gas purity and cleaning techniques.The OERLIKON CITOWAVE power sources have specialoperating modes used when welding aluminium alloys,the Spray ModalTM and Cold Double PulseTM modes,which reduce the risk of micro porosity, increase penetrationand minimise distortion when welding, see pages 18 & 19.

ALUFIL AlMg4.5Mn and ALUROD AlMg4.5Mn are 5183 gradealuminium alloy MIG wire and TIG rod respectively usedfor welding 5083, and similar alloy grades, where a combinationof corrosion resistance with high joint strength and toughnessare required.

Within an LNG import terminal and regasification plant there isassociated pipe work, which is typically fabricated in 300 seriesstainless steels with expansion loops to accommodate the highcoefficient of thermal expansion. Typically, 304L pipe is joinedusing the MMA and TIG processes, for MMA, OERLIKONBASINOX 308LT and for TIG, OERLIKON INERTROD 308L.For dissimilar steel joints of 300 series stainless steels toC-Mn pipe work, MMA OERLIKON BASINOX 309L and TIGOERLIKON INERTROD 309L are preferred.

OERLIKON is regularly involved in engineering programmesto generate innovative solutions to new applications,in thiscase resulting in specialist welding consumables designedfor the fabrication of 9%Ni steel.

OERLIKON Welding Consumablesfor 9%Ni materialOERLIKON has developed welding solutions for 9%nickel steelsbased on both matching and nickel alloy material solutions.

Currently, matching solutions are not considered for thefabrication of large LNG storage tanks. 9%Ni matching solidand OERLIKON FLUXOCORD SAW wires in combination withthe GTAW or PAW processes have demonstrated the abilityto achieve high levels of weld metal toughness and tensilestrength, however the levels of deposition efficiency are notsufficient for the fabrication of large LNG storage tanks. Whenpost weld heat treatment is possible, the SAW process with9%Ni matching consumables becomes an option.

Large cryogenic storage tanks are subject to expansion andcontraction in service. The selection of welding consumablesis related to the capacity to limit the stress concentration inthe weld metal responsible for thermal fatigue. Therefore,non matching welding consumables should be selected withan expansion coefficient as close to 9%Ni steel as possible.

Comparison of thermal expansion for 9%Nickel steel and OERLIKONconsumables FREEZAL ENi9 & BASINOX 308 LT.

Stainless steel welding consumables are widely used forcryogenic applications, e.g. INERTROD 308L, INERTFIL 308L,BASINOX 308LT, but are not considered when fabricating largetanks because of the risk of failure linked to the differentialcoefficients of expansion in comparison to ASTM A 353/553or EN 10028-4 X8Ni9 grades.

OERLIKON MMA electrodeThe new OERLIKON FREEZAL ENi9 electrode is a nickel baseMMA electrode designed to deposit weld metal with acoefficient of expansion which is close to the 9%Ni steel usedfor large LNG storage tanks.

FREEZAL ENi9 has optimised mechanical properties, ductility andelongation, meeting the most stringent CTOD specifications with safeand reliable levels of lateral expansion required down to -196 °C.

The coating design and use of specialist raw materials reduces thelevel of residual and impurity elements responsible for hot cracking,FREEZAL ENi9 satisfies all stringent hot cracking tests, such asVarestrain.

OERLIKON FREEZAL ENi9 has a deposition efficiency of 150%enabling high levels of MMA productivity during fabrication in allwelding positions. OERLIKON DRY packaging ensures theseelectrodes are ready for use during on site storage tank construction.

Typical specification for weld metal mechanical properties:

which is achieved using the new OERLIKON consumables:

OERLIKON Flux & Wire solutionsfor SAW processOP 76 is a agglomerated fluoride basic type submerged arc fluxwith a Boniszewski basicity index of 2.7. The high basicity index willprovide a hot crack free weld metal. The metallurgical behaviourwith respect to carbon, manganese and silicon is neutral. OP 76 isused in combination with NIFIL 625 solid wire for welding 9%Nisteel for as welded applications, typically in the PC or 2G position.Stable operation on AC polarity, the weld deposit has a highresistance to hot cracking and excellent cryogenic weld metalfracture toughness.

OP F77 is a fused calcium silicate type submerged arc flux with aBoniszewski basicity index of 1.3. Especially designed by OERLIKONto give the best operating condition in the horizontal position, weldingboth sides simultaneously. The metallurgical behaviour with respectto silicon is neutral and manganese is reduced. Used in combinationwith NIFIL C276 solid wire for welding 9%Ni steel for as weldedapplications, this combination is optimised for welding in the PC or2G position with excellent slag removal. Stable operation on ACpolarity, the weld deposit has a high resistance to hot crackingvalidated by Varestrain testing and excellent cryogenic weld metalfracture toughness. OP F77 is ideal for tank construction because ofits non hygroscopic properties.

Both SAW solutions fullfill the most stringent engineering specificationin terms of CTOD and lateral expansion at -196 °C and hot crackingsensitivity testing.

Product Focus

The challenge when fabricating low alloy ferritic steels forcryogenic applications is to produce high strength joints withreliable fracture toughness at the design temperature, without riskof hydrogen induced cracking.

OERLIKON welding consumables are designed to satisfy the moststringent requirements in terms of diffusible hydrogen level.The manufacturing process has been designed by OERLIKONto produce very low hydrogen consumables with a high resistanceto subsequent moisture pick-up during use.

OERLIKON has a globally recognised expertise in the metallurgyand design of welding consumables for low temperature andcryogenic applications. The results of the many years ofsystematic R&D in this area are reported in published articles,where acicular ferrite is the microstructural constituent identifiedas critical for generating high levels of joint fracture toughnessat cryogenic temperatures in low alloy ferritic weld metal.

Weld metal acicular ferrite is not only optimised in OERLIKONconsumables by deposit chemistry and the selection of specialistdeoxidation systems in basic flux systems, but by the consistentsourcing of high quality raw materials. Raw material selection ispermanently in the focus of our experts to ensure weld metalswith very low levels of residual and impurity elements.

These advanced techniques applied to the design of OERLIKONwelding consumables have contributed to the global recognitionfor reliable and high quality low temperature construction whenusing OERLIKON welding products.

The processing of natural gas involves removal of propaneand other gases from the raw gas, in order to preventcondensation of these volatiles in natural gas pipelines.

Propane is a flammable non toxic gas, which is heavierthan air. It is a gas in normal atmospheric conditions, 15 °C,760 mm Hg, the boiling point is -42 ºC.

Liquid Propane Gas, LPG, is generally stored onshore in bothspherical and mounded pressurised storage, with the latterbeing the only solution allowed in many countries.

Welding solutions are based on optimised C-Mn and 1-2.5%Ninickel bearing weld metals delivering high toughness joints forservice temperatures in the range -50 ºC to -80 ºC.

Ammonia is a gas in normal atmospheric conditions, 15 °C,760 mm Hg, which is colourless, slightly flammable and toxicwith a pungent odour, the boiling point is -33 ºC. Ammonia isstored in its refrigerated form between -50 ºC and -80 ºC.

Welding solutions are based on optimised C-Mn and 1-2.5%Ninickel bearing weld metals delivering high toughness jointsfor service temperatures in the range -50 ºC to -80 ºC.The propensity to stress corrosion cracking is a designconsideration.

Ethane is a gas in normal atmospheric conditions, 15 °C,760 mm Hg, which is flammable and non-toxic, the boilingpoint is -89 ºC. The storage and handling requirementsof ethane are generally specified at a service temperature of-101 ºC.

When fabricating 3.5%Ni steels for ethane storage, matching3.5%Ni bearing weld metals are used.

Acetylene is a gas in normal atmospheric conditions, 15 °C,760 mm Hg, which is a colourless, non-toxic but narcotic, and ishighly flammable. Isolated in the pure state, it is a highly unstablecompound, and decomposes with ignition within a wide range ofpressures and temperatures, the sublimation point is -84 ºC.

The storage and handling requirements of acetylene are generallyspecified at a service temperature of -101 ºC.

When fabricating 3.5%Ni steels for acetylene storage, matching3.5%Ni bearing weld metals are used.

Carbon dioxide is a gas in normal atmospheric conditions,15 °C and 760 mm Hg, which is colourless, odourless,non-flammable of low chemical activity and toxic only in highconcentrations, the sublimation point is -79 ºC.

The storage and handling requirements of carbon dioxide aregenerally specified at a service temperature of -101 ºC.

When fabricating 3.5%Ni steels for Carbon Dioxyde storage,matching 3.5%Ni bearing weld metals are used.

Ethylene, also known as ethene, is a gas in normal atmosphericconditions, 15 °C, 760 mm Hg, which is flammable and non-toxic,the boiling point is -104 ºC. The storage and handling requirementsof ethylene are similar to LNG but at a generally specified servicetemperature of -120 ºC.

Welding solutions for liquid ethylene gas, LEG, are based on the20.16 composition for the welding of 5%Ni steels, due to theexcellent cryogenic fracture toughness, however the weldingsolutions given for fabricating 9%Ni steels are equally applicablefor joining 5%Ni steels.

Argon is a gas in normal atmospheric conditions, 15 °C and760 mm Hg, which is a colourless, odourless, non-toxic non-flammable and tasteless. It is distinguished by perfect physicaland chemical stability. At atmospheric pressure and temperaturesbelow the boiling point of -186 °C, argon is a colourless liquid,which is heavier than water.

Welding solutions are the same as those shown for LNG.

Oxygen is a gas in normal atmospheric conditions, 15 °C and760 mm Hg, which is colourless, odourless and tasteless.At atmospheric pressure and temperatures below the boiling point-183 °C, it is pale blue liquid, slightly heavier than water. Liquidoxygen, LOX, is stored in single containment tanks fabricated in9%Ni steel and because of the relatively small volumes, 304Lstainless steel may also be used for the prime container.

Welding solutions are the same as those shown for LNG.

SpeedShortArcTM

(SSA)

The Speed Short ArcTM allows a high travel speed due to a rigid arcand a cold regime. It is very effective for welding thin steel plates,working in position and in closed angle and filling bevels. TheSSATM is used for short circuit welding though the normal globularregime travel speed domain.

■ Increase in travel speed■ Reduced distortion

(thin steel sheets)■ Suited to welding in position■ Tolerance and usability

CITOWAVECITOPULS II

SoftSilencePulseTM

(SSP)

The Soft Silence PulseTM is a quieter pulsed mode mainly intendedfor stainless steel welding applications. The SSPTM produces asofter but very stable arc with good wetting of the weld bead.This waveform significantly reduces spatter and gives a very fineappearance to the weld bead.

■ Reduction of noise■ Good wetting of the weld bead■ Reduction of spatter■ Good weld bead appearance

CITOWAVE

ColdDoublePulseTM

(CDP)

The Cold Double PulseTM produces very high quality welds on thinmaterial while avoiding distortion. CDPTM gives a TIG appearance tothe weld and is very effective on very thin aluminium or stainlesssteel sheet (< 2 mm). The operating technique is made easier dueto good control of the weld pool even on badly-prepared sheets.This sequencer mode automatically chains hot arc and cold arcregimes together.

OXYTOME RS

PLASMATOMETWIN RS

Reinforced structurefor OXYTOME / PLASMATOME (RS)For plates wider than 4 m or for certain equipment,a reinforced structure is used to ensure movement stabilityand precision.

TWIN RS structure for OXYTOME / PLASMATOMEThe TWIN RS structure is designed as a double transversalbeam equipped with liner guides and bearing, located in asafety position away from heat radiation. This machine isspecially suitable for bevelling head applications requiring atransversal cutting stroke over 4 m or tool holder of 800 mm.Finally, the accuracy of this machine is particulary suitablefor HP plasma applications.

CYBERTOMEDesigned as a “machine tool” concept, stated in termsof accuracy and repeatability according to current standards.This design can be modified to accomodate special requirements,and allows sheet metal cutting of 8 m width and more.

PlasmalongitudinalThis system allows the

operator to manually tilt

the torch in order to work

plasma bevels along the

longitudinal axis.

PlasmastraightThis system is used to

work bevels along the

axes using a plasma torch.

3 models of table adapted to the process of cutting

Extraction table for dry cuttingThe AZURMATIC table with air extraction offers unrivalledefficiency in terms of fume extraction due to its unique systemof transverse extraction ducts.Robustly designed in one-piece or modular form, the table isdivided over its length into 1 metre sections, extraction takingplace across the full width of the table on the module inoperation only. Mechanical grills actuated by the displacementof the machine provide suction under the sheet at the place ofcutting only.This principle of operation guarantees optimum extraction,irrespective of the size of the sheet being cut, while maintaininga modest extraction air-flow rate.

Technical characteristics:

■ Transverse duct extraction system,■ Division into 1 metre sections over the length of the table

(500 and 750 mm sections on demand for intensive use),■ Removable slag boxes,■ Removable workpiece supporting frame with flat irons

(section 100 x 6 mm) and wire mesh grid (50 x 50 x 5 mm),■ Maximum capacity: sheet up to 300 mm thick.

Constant water level extraction tableVarious processes, especially plasma cutting with non-immersed water vortex, require a cutting table with waterrecovery and fume extraction.

This table provides both possibilities. This process (which ispatented) avoids the need for filtering equipment upstream offume extraction.


■ One-piece design divided into 630 mm sections,■ Standard lengths of 3 to 12 m,■ Standard widths: 1.5 - 2 - 2.5 and 3 m,■ Height: 700, 800 or 920 mm,■ Maximum capacity: sheet thickness 50 mm.


■ Modular construction in lengths of 1.5, 1.75 and 2 m,■ Widths to demand,■ Pivoting workpiece support frame for easier, faster cleaning.

Variable water level tablesVariable water level tables are specifically intended for immersedplasma cutting.This procedure limits pollution by solid or gaseous matterand gives protection against audible and visual stress.It improves accuracy of cutting while limiting distortion caused by heating of the workpiece.
