The tie-bolts of connecting rods and their relevant contact areas with shank are the most stressed points of reciprocating compressor and engines. A normal FEA is not sufficient to accurately design these parts. CST designs these components within an elastic-plastic stress analysis, which results are then post-processed for evaluatìon of the fatigue safety coefficient.
The connection between piston rod and crosshead is one of the most stressed points of reciprocating compressors. CST designs this threaded connection by the aid of an elastic-plastic stress analysis whose results are post-processed for evaluation of the fatigue safety coefficient.
A lack of contact pressure between the two halves of the horizontally split compressor caused serious problems of toxic gas leakage. An accurate FEA allowed the restoration of an adequate contact pressure in the critical zones, guarenteeing the complete avoidance of dangerous leakages solving the problem experienced by the customer.
