The gasket has to have the correctsize.

1. Gasket dimensions

Cut the bolt holes just a bit largerthan the bolts to simplify thecentralization of the gasket.

The inner diameter of the gasketshould not be smaller than the innerdiameter of the flange.

The gasket should be storedhorizontal to avoid tensions andpermanent warpage. Ideal storage conditions are: temperature < 25C air humidity 50 - 60% Darkened storage roomStore the gasket in a clean condition(ideally in a plastic bag).

All types of gaskets (metallic gas-kets, PTFE gaskets, fibre reinforcedgaskets etc.) should be handled withthe same care and attention. Avoid carrying small gaskets in apocket to protect the gasket fromdamage.

Do not bend the gasket and do notdamage the surface.

Carry ready cutted gasketscarefully, ideally in some form ofprotective cover.

Pay attention that all bolts which are designed for the flange areinstalled. Check if the used bolts are suitablefor the given operating temperatures. Tighten the bolts cross-wise withthe correct torque (calculation withKLINGER expert 5.1). Ensure that there is no corrosionon the bolts because this can effectthe function of the bolt. Never Re-use bolts.

Bolt properties

Use a nut which has a specifiedproof load 20% greater than theultimate strength of the fastener. Use standard threads, rather thanfine. Use the correct lubricant.

Nut properties

Use the same material for thewashers and the nuts. Use washers to: bridge slotted or oversized holes even interface forces between jointcomponets reduce problems of fatigue byspreading the load placed by thefastener on the joint.

Washers

At first make sure that thefollowing tools are available and ingood condition: the correct gasket chosen for thespecific application a calibrated torque wrench a wire brush lubricants for the bolts.

The tools

Make sure that the flange surfacesare clean. Check the bolts and the flangesurface if they are technically ok andfree from any seriuos defects. Always brush in the direction ofthe grooves. To avoid damage on the flangesurface please use a brass drift.

Cleaning of all flange surfaces

Make sure that the flanges areparallel and report all irregularities.

Flange conditions

Insert the gasket carefully betweenthe flanges. The gasket has to be centralized inthe flange. Ensure that the gasket is installedin a dry state. It is important that the gasket isnot pinched or otherwise damagedwhen bringing the flanges together.

Apply lubricant to the bolt and thenut threads as well as to the face ofthe nut to reduce friction whentightening Pay attention that the lubricantdoes not contaminate the gasket orthe flange surfaces. The recommended servicetemperature of the lubricant has to bewithin the process servicetemperature limits.

The required torque value can becalculated with KLINGER expert 5.1. Make at least 4 stages to therequired torque as follows: finger tighten bolts use 30% of the required torque use 60% of the required torque use the full torque Close the torquing with one finalpass in a clockwise sequence.

For safety reasons never re-use agasket. The cost of a gasket is minimalcompared with the costs which willcome into being of a down time of theplant.

If retightening is considerednecesary, this should only be done atambient temperatures before orduring the first start-up. Never retighten compressed fibregaskets at higher operating tempera-tures and longer operating times.
