Numerical study for reliability assessment of a corroding pipe to flange weld joint over its lifetime

نویسندگان

چکیده

Numerical model of a corroded weld joint connecting pipe to flange using finite element method was developed, and coupled with usual stress models. The structure material has been characterized experimentally. Monte Carlo simulations, FORM SORM methods have applied for estimating reliability failure probability under corrosion residual effects. A numerical case various rates conducted determine the welded connection flange. obtained results show that heat affected zone is very sensitive effects due welding process.

A Stress Analysis of Pipe Flange Connections

The use of pipe flange connections is standardized in the codes of JIS, ASME, DIN and so on. However, these codes are almost entirely dependent on experience, and subsequently some problems concerning pipe flange connections have been encountered. In the present paper, the distribution of contact stresses which governs the sealing performance is analyzed as a three-body contact problem, using a...

Numerical study of slotted web drilled flange moment frame connection

Beam connections with reduced drilled section and slotted web have been presented after the Northridge earthquake (1994). Their new geometrical shapes have been resulted in weakening of beams and subsequently the bette rperformance of connections in the earthquakes. In this research, the advantages of both connections, mentioned above, have been studied in the Slotted Web Drilled Flange (SWDF) ...
