The data in this table are subject to becoming obsolete, so you should take advantage of available Chemical Resistance Assistant supplied by the manufacturer.
Two versions of Chemical Resistance Assistant are available:
- on-line version - available at http://www.klinger.co.at/mediaresistance/
- off-line version (Polish, English or German language version) - download from http://www.klinger.pl/oprogramowanie.html
Version to be installed on a PC with the ability to update the table of resistance.
Resistance Assistant allows you to:
- finding the right sealing material depending on the chemical, its concentration and temperature
- checking the resistance of the sealing material for different chemicals.
A warranty on the function of the gasket can not be given as the proper function of a sealing connection is dependent on many additional factors on which the manufacturer has no bearing.
A sufficient surface pressure is required in any case.
The following guidelines are designed to ensure the optimum performance of our gasket materials:
1. Choosing The Right Gasket
There are many factors which must be taken into account when choosing a gasket material for a given application including the chemical compatibility, temperature and pressure. Please refer to the information given in this catalogue or our software program; Klinger Expert for advice. If you have any questions regarding the suitability of material for a given application, please contact Klinger Technical Department.
2. Gasket Thickness
Gasket material should be as thin as possible. Increasing the thickness of the material decreases the load-bearing capacity of the gasket. Thinner materials also have better torque retention characteristics.
3. Flange Condition & Flange Surface Finish
Ensure all remains of the old gasket material are removed and the flanges are clean and in good condition. We typically recommend a flange surface finish of 3.2μm (125μ”) to 6.3μm (250μ”) for our gasket grades when used on standard pipe flanges. See page 26 for more details.
4. Gasket Compounds
Ensure all soft cut gaskets are installed in a dry state - the use of jointing compounds is not recommended. Releasing agents such as grease or oil containing compounds are not required and can adversely affect the material, lowering the torque retention properties. To aid gasket removal, Klinger materials have an antistick finish.
5. Gasket Dimensions
Ensure gasket dimensions are correct. The gasket should not intrude into the bore of the pipework and should be installed centrally.
Wire brush stud/bolts and nuts (if necessary) to remove any dirt on the threads. Ensure that the nuts can run freely down the thread before use. Apply lubricant with a known friction coefficient to the bolt threads, to the nut threads and to the face of the nut to be tightened.
7. Joint Assembly
It is recommended that the bolts are tightened using a controlled method such as torque or tension, this will lead to greater accuracy and consistency than using conventional methods of tightening. If using a torque wrench, ensure that it is accurately calibrated. For torque settings please refer the Klinger Expert or contact our Technical department who will be happy to assist you. Carefully fit the gasket into position taking care not to damage the gasket surface. When using torque, tighten bolts in at least three stages to the required torque as follows:
- Finger tighten nuts.
- Carry out tightening, making at least three complete diagonal tightening sequences i.e. 30%, 60% and 100% of final torque value.
- Continue with one final pass - torquing the bolts/studs in a clockwise sequence.
Provided that the above guidelines are followed retightening of the gasket after joint assembly should not be necessary. If retightening is considered necessary e.g. in the case of thicker gaskets which are more susceptible to creep, then this should only be performed at ambient temperature before or during the first start-up phase of the pipeline or plant. Retightening of compressed fibre gaskets at higher operating temperatures and longer operating times may lead to a failure of the gasket connection and should be avoided.
For safety reasons, re-use of gaskets is not advisable.
