KLINGER

Spiral Wound Gaskets

KLINGERmaxiflex mounting instructions

The principleThe KLINGERmaxiflex function isbased on the metal winding/ filler re-lationship and the flange surfaces.

The surface roughness should beapprox. Ra 3.2 µm. KLINGERmaxiflexgaskets can be used in flanges withlarger surface roughnesses, but in thiscase the bolt loads should be increa-sed so as to ensure proper function ofthe gasket.

When the KLINGERmaxiflex gas-ket is compressed during mounting,the homogeneous filler „flows“ intothe irregularities of the flange. Themetal windings enclose the filler and,at the same time, ensure the strengthand elasticity of the gasket.

If the gasket is equipped with anPTFE filler it must have an inner ringsince the PTFE permits no furthercompression, as is the case with otherfillers. On the one hand, it preventsthe gasket from springing open andon the other, penetration of the flo-wing PTFE in the pipeline. The largerthe surface roughnesses in the flangesurface, the larger the surface loadrequired to permit a flow of the PTFEin the irregularities.

MountingThe bolts should be free of damageand lubricated with high-temperatureresistant greases before mounting.

Insert the gasket and fasten boltsfinger-tight.

Next, tighten the bolts crosswise(see sketch) in at least 3 to 4 passes.The more passes you perform, themore uniform the force which is intro-duced into the flange-gasket system.

In the last pass, the bolts must betightened only clockwise.

Certified Fire Safe According to API 6FB!

Wide choice of materials for metal strip and filler. Suitable for high pressures and temperatures.Recommended for flanges with tongue and groove.

Type R

Solid metal outer ring used as a centerring device and compressionstop.Used on raised face and flat face flanges.

Type CR

Solid metal inner ring.Use with high pressures and temperatures.Male to female flanges.

Type RIR

This gives the gasket recoveryforces which provide for a reliablesurface load even at fluctuating oper-ating conditions.

In the present 8 versions, thebasic element is added by innerand/or outer rings as needed.

The design principle of theKLINGER Spiral-Wound GasketsThe basic element of every gasket isthe wound core. The V-shaped metalstrip is spirally wound with the soft-material filler.

To improve the mechanicalstrength and other sealing character-istics, some layers at the beginningand at the end are wound without softmaterial and spot-welded over thetotal circumference.

The constant tensile force duringthe complete winding process permitsa defined, constant thickness of thestructure.
