LNG Cryogenic Triple Eccentric Metal Seated

Triple eccentric design principleMetal seated high pressure butterfly valves provide bi-directional bubble tight shut off which achieved by introducing state of the triple eccentric disc geometry.The valve shaft is off set against the seat and the center line of the valve body respectively. The seating edges are machined with a continuously changing slope from an angle on top of the oval seat ring to an angle at the opposite side. This geometry ensures that the seat ring stays clear of the seat except at the final shut off position which results long life seat.

Metal to metal seatVarious metal seals are available to comply with each temperature and pressure service applications.Solid metal seals are often used for temperatures above 510 and up to 815 or Cryogenic service.The seal leakage meets API 598 or API 6D.The solid metal seating valve can be operated in a temperature range of -196 to +815 .Valve for cryogenic application shall be provided with extended stem.

Materials Specification for ACE Cryogenic ValvesAll materials supplied for the valve components are suitable for operation in LNG installations.such as stainless steel 316 or 316L, stainless steel 304 or 316 for LPG.Impact test is carried out on pressure retaining parts (body, bonnet, disc) of cast material, according to ASTMTesting Procedures, with Charpy V Specimen, at-(negative) 196 .

Following minimum test results are required:average (on 3 specimen) not less than 3.5 kgm/minimum (on 1 specimen) not less than 3 kgm/

Fire Safe DesignValve is designed to be fire safe construction.Sealing system is designed to have a KEL-F seal ring inserted into disc for sizes of 2” and larger. This KEL-F sealring is replaceable to make it possible easy maintenance.In addition, soft sealing by KEL-F seal will perform an excellent and flexible sealing characteristic with minimumleakage at critical service condition at temperature of negative 196 celsius.In emergency of fire accident, even if this KEL-F seal ring is destroyed, sealing system can be secured bysecondary metal to metal sealing.The valve provided with metal seat only shall be maintained the same condition in emergency of accident.

Physical Properties of "KEL-F"HIGH COMPRESSIVE STRENGTH AND SUPERIOR CREEPING RESISTANCE“KEL-F” (polychlorotrifluoroethylene: PCTFE) has high compressive strength and creeping resistance, and issuperior to “TEFLON”(polytetrafluoroethylen: PTFE), please refer to the attached data.Even under intense low temperature(liquefied H2 : -255 ), “KEL-F” has superior elastic memory and tendency.The valve provided with metal seat only shall be maintained the some condition in emergency of accident. RESISTANCE AGAINST LOW AND HIGH TEMPERATURE“KEL-F” is applicable under intense temperature condition from -200 to +200 without hindrance.

WATER AND MOISTURE RESISTANCE“KEL-F” is superior characters of anti-moisture and complete water resistance; moisture absorption is nil.Even in water or high humidity conditions, “KEL-F” has perfect stability of dimensional and electrical characters.

FACILITIES AGAINST IMPACT FORCE AND WEAR OUT“KEL-F” has superior facilities to resist impact force and wear out, and suitable for a long life service.

MINIMUM SHRINKAGEEven at liquefied N2 temperature (-196 ) condition, shrinkage and deformation are very small and ignorable.

CONCLUSION“KEL-F” is the most suitable material for seal-rings of cryogenic valves by above mentioned reasons.

Schema of Cryogenic Butterfly valveACE cryogenic valves are widely used throughout the world, from liquefaction plants, to liquefied gas carries, receiving tank terminals as well as peak shaving plants, in a critical and hazardous service conditions down to the temperature as low as -196 .The materials used throughout are of austenite stainless steel which maintains its strength at low temperature and the sealing system is a soft sealing, fire safe type incorporating Kel-F ring inserts into disc which ensures trouble-free operation.The metal seated exchangeable double eccentric or triple eccentric butterfly valve is available.The valves are of extended bonnet construction to create an insulation gas column between the plastic stem packing and the cold fluid.This prevents hardening and shrinking the packing and allows the external operating section of the valve remain “warm”The valve of butt-welding end has side entry maintenance system to make the replacement of sealing ring without removing the valves from the pipes.All valves are tested at cryogenic temperature which can examine the performance as critical as in an actual service condition.

Operations The following operation of the valve is available, the choice depending upon the valve location and the type of work and service for which the valve is used.

Manual lever operation Manual worm gear operation Single or double acting pneumatic actuator operation Hydraulic actuator operation Electric motor actuator operation

A - Nominal outside diameter of pipe, inches.AA - Nominal outside diameter for cast steel valves, inches (see table).B - Nominal inside diameter of pipe, inches.t - Nominal wall thickness of pipe, inches.C - A-0.031 - 1.75t - 0.010.Regardless of tolerances specified for dimensions A and B, the thicknessof the welding end shall never be less than 87 1/2 percent of the nominalthickness of the pipe.For complete dimensions, details, and tolerances, see ASME B 16.25.

When the thickness at the welding end of the valve is greater than that ofthe mating pipe, and when the additional thickness increases the outsidediameter, a taper weld having a slope not exceeding 1:3 may beemployed, or the greater outside diameter may be extended back in amanner within the maximum slope lines indicated in Figs. 1A and 1B.The trasmetion shall be of a shape avoiding sharp re-entrant angles andabrupt changes in slope. The profile of the outside contour shall be at themanufacturer’s option provided above conditions are met.

For a joint without a continuous backing ring, the inside contour of thevalve end shall be bored to a diameter B to a depth of 1½t. The insidediameter of a valve end beyond this machined surface may be eitherlarger of smaller than the inside diameter of the pipe. The trasmetion shallbe of a shape avoiding sharp re-entrant angles and abrupt changes inslope. See Figs. 1A and 1B. (Trasmetion shape also applies to Fig. 2 and3.)

For a joint with a continuous rectangular backing ring, the inside contourof the valve end shall be a straight bore of diameter C, ½in. deep. Thisdepth is based on a backing ring 3/4 in. wide; but if a wider ring is used,the depth shall be increased to provide the 1/8 in. minimum endclearance indicated. See Fig. 2.

For a joint with a continuous tapered backing ring, the inside contour ofthe valve end shall be taperbored from diameter C at the lip, taperling at10 deg. to a taper length of 7/32 in. minimum. Beyond this taper length,the bore may be a straight diameter of dimension B, or the 10 deg. tapermay be extended to the inside port diameter. See Fig. 3.

* See Figs. 1A and 1B for Outside Contours.
