Installation instructions for

KLINGER® gaskets

■ 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 < 25°C■ 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.

Installation instructions for

KLINGER® gaskets

■ 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.

We have devised a tried and tested method,

to guide you step by step to the right gasketfor your needs.

1. Applications overview:The gasket characteristics comparedwith the criteria to be met in typicalapplication.

2. Product documentation:A separate data sheet is supplied foreach gasket in our range.The pT diagrams are an invaluableaid to selecting the gasket most suitable for a particular application.

3. Data on chemical resistance:This section indicates the resistanceof the individual Klinger gaskets toover 200 chemicals in common use.

4. Technical information by Fax:Let us have the details of your particular gasket requirements andyou will receive a prompt reply, insome cases within 24 hours.

5. Sealing calculationson your PC:For the experienced specialist wehave developed a powerful programwhich will answer all your questionson gasket construction, design andmaintenance. We supply the softwarewith on-line help.

6. Ideally you should run your own tests:We will supply the materials youneed to carry out tests under yourown operating conditions.

7. On-sit advice:With particularly difficult problemswe shall be glad to advice you on-site. We can supply productsadapted from our existing range orcustom-formulated products.
