TIGHTNESS PREDICTION OF BOLTED FLANGED CONNECTIONS WITH ELASTIC WASHERS

摘要：

Bolted flanged connections are commonly used in industrial equipment and pipeline, and their failure is mainly caused by leakage. Elastic washer is a kind of elastic compensating element. It can effectively compensate creep deformation and relaxation of gaskets, bolts and flanges, thus improve the tightness of the joints operating at elevated temperature. The concept of the tightness of bolted flanged connections was proposed. The deformation compatibility equation of the joints was established, and the tightness prediction method of the joints with elastic washers at elevated temperature was proposed. The research results have been applied to the bolted flanged connections in some petrochemical plants, and the tightness of these joints was obviously improved.
