Risk-Based Inspection for Bellows-Type Compensator Manufacture and Testing
For the timely recognition of possible failures in the operation of the bellows equipment, regulatory documentation recommended only a continuous amount of acceptance tests. The use of a simplified inspection system by the method of independent random sampling from the party, with further extension of the results to all products is not allowed. Simplified inspection potentially reduces the reliability of the bellows compensator.
The simulation of testing processes allows, based on the calculated data, to optimize the sequence and order of testing with preservation of the required product quality and the requirements of regulatory and technical documentation.
