With the varying problems that occur during hook-up and commissioning or shutdown operations, it has become apparent that an integrated service is required. IMKOSAN’s response has been to form a team capable of finding and repairing leaks.The bolt load on the leaking flange is initially taken to the minimum acceptable level in accordance with specifications. The tension is then progressively increased in increments until the leak is sealed or until the maximum recommended bolt load is reached. If at this bolt load the leak has not sealed then this will be reported to the client to approve further bolt tensioning or allow inspection, gasket renewal or reworking. Procedures will be supplied including tensioning or torquing data sheets on specific classifications of joints and bolt material calculations.
